Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated:
1
00:00:09,706 --> 00:00:12,440
I'm just about to head through
the gates of one of Britain's most
2
00:00:12,465 --> 00:00:15,241
secret military establishments...
3
00:00:15,266 --> 00:00:17,640
...Faslane, on the west coast
of Scotland.
4
00:00:19,465 --> 00:00:22,801
This is Britain's Royal Navy
Submarine Base,
5
00:00:22,826 --> 00:00:26,281
and usually it would be impossible
for me to get in here,
6
00:00:26,306 --> 00:00:28,390
especially with a television camera.
7
00:00:29,415 --> 00:00:31,131
But today is different.
8
00:00:32,665 --> 00:00:35,921
I've been vetted to the highest
level and I've had to sign
9
00:00:35,946 --> 00:00:37,570
the Official Secrets Act...
10
00:00:37,595 --> 00:00:41,281
...because behind this fence
is Britain's most secret
11
00:00:41,306 --> 00:00:43,851
and most powerful weapon of war.
12
00:00:53,595 --> 00:00:57,921
Security at Faslane is tight
because this is the home
13
00:00:57,946 --> 00:01:00,491
of Britain's nuclear
submarine fleet,
14
00:01:00,516 --> 00:01:03,721
and our Trident nuclear missiles.
15
00:01:05,056 --> 00:01:09,211
Welcome to the most secure
operational base in the UK.
16
00:01:11,236 --> 00:01:14,770
We operate from here, a nuclear
deterrent for NATO
17
00:01:14,795 --> 00:01:16,801
and the UK and her allies.
18
00:01:16,826 --> 00:01:20,241
And if you've got that level
of sophistication,
19
00:01:20,266 --> 00:01:24,211
technology and power in one place,
20
00:01:24,236 --> 00:01:27,801
you've really got to protect
it and protect the knowledge
21
00:01:27,826 --> 00:01:29,770
that goes with it.
22
00:01:32,026 --> 00:01:35,721
Over 6,500 people work here
at the base,
23
00:01:35,746 --> 00:01:39,921
but access to the nuclear submarines
is highly controlled.
24
00:01:41,545 --> 00:01:44,961
After months of discussions, I've
been given permission to film
25
00:01:44,986 --> 00:01:48,520
on board one of the UK's
Trident submarines.
26
00:01:53,746 --> 00:01:55,921
So what happens now for me, exactly?
27
00:01:55,946 --> 00:01:58,961
Well, you're going to join HMS
Vengeance going through the last
28
00:01:58,986 --> 00:02:02,131
of her training sessions at sea.
29
00:02:02,156 --> 00:02:05,031
But before we get there, we've got
to go into the secure area,
30
00:02:05,056 --> 00:02:07,520
So I'm going to tell you to cut
the camera now
31
00:02:07,545 --> 00:02:09,801
because you can't film inside
a secure area.
32
00:02:09,826 --> 00:02:10,961
Sorry, yeah.
33
00:02:20,585 --> 00:02:24,801
Some hours later, I'm being taken
out into the Irish Sea,
34
00:02:24,826 --> 00:02:28,281
which is where I'll transfer
to HMS Vengeance.
35
00:02:33,236 --> 00:02:35,721
I don't know where we're heading,
I don't know how long
36
00:02:35,746 --> 00:02:37,131
I'm heading out for here.
37
00:02:39,236 --> 00:02:40,440
I'm...
38
00:02:40,465 --> 00:02:43,281
...l'm really nervous, I don't mind
admitting that at all.
39
00:02:52,876 --> 00:02:54,961
It's there... Right there!
40
00:02:58,335 --> 00:03:00,310
That is HMS Vengeance.
41
00:03:04,026 --> 00:03:06,001
Oh
42
00:03:06,026 --> 00:03:07,721
Unbelievable!
43
00:03:10,795 --> 00:03:13,131
Oh, my word, just look
at the size of it.
44
00:03:19,876 --> 00:03:23,310
HMS Vengeance is 150 metres long...
45
00:03:23,335 --> 00:03:26,560
...and weighs 15,000 tonnes.
46
00:03:26,585 --> 00:03:30,281
She's one of four Vanguard
class submarines.
47
00:03:38,106 --> 00:03:40,001
Ready t0 go on?
Yeah, if you're happy.
48
00:03:40,026 --> 00:03:41,601
Thank you.
49
00:03:41,626 --> 00:03:46,921
In just a few clays, HMS Vengeance
will begin her patrol...
50
00:03:46,946 --> 00:03:50,411
...where she takes over as the UK's
nuclear deterrent.
51
00:03:51,795 --> 00:03:54,201
She'll disappear deep into the ocean
52
00:03:54,226 --> 00:03:57,801
in case our nuclear missiles
are ever called upon.
53
00:03:57,826 --> 00:03:59,411
Big box.
54
00:03:59,436 --> 00:04:01,560
It's not heavy, like,
it's just cumbersome.
55
00:04:01,585 --> 00:04:02,921
Happy for me to go down?
56
00:04:02,946 --> 00:04:04,921
Yeah, thank you.
57
00:04:04,946 --> 00:04:06,161
Now...
58
00:04:06,186 --> 00:04:07,491
Yeah.
59
00:04:08,626 --> 00:04:11,491
All right, this is it then,
there is no turning back now.
60
00:04:11,516 --> 00:04:13,520
Last breaths of fresh air.
61
00:04:13,545 --> 00:04:14,721
God!
62
00:04:16,876 --> 00:04:19,851
For four clays and nights,
I'll be living with the crew
63
00:04:19,876 --> 00:04:22,881
on the final leg of their
undersea preparations...
64
00:04:22,906 --> 00:04:25,491
INAUDIBLE CHATTER
65
00:04:25,516 --> 00:04:28,951
...before they head off on their
tour of duty.
66
00:04:28,976 --> 00:04:31,161
OK, at ease...
67
00:04:31,186 --> 00:04:34,201
I've already been told that
I won't see everything.
68
00:04:35,386 --> 00:04:39,520
So much on this boat is
classified as top secret.
69
00:04:46,665 --> 00:04:50,281
Captain Darren Mason is in charge
of HMS Vengeance.
70
00:04:50,306 --> 00:04:54,131
It's his first time in command
of a Trident submarine.
71
00:04:57,357 --> 00:04:58,932
Hello. Well, come on in.
72
00:04:58,957 --> 00:05:00,840
I thought I'd better
come and let you know
73
00:05:00,865 --> 00:05:03,040
I am here, yes. Firstly,
welcome to the submarine.
74
00:05:03,065 --> 00:05:04,660
Thank you very much for having
me on board.
75
00:05:04,685 --> 00:05:07,070
It's fantastic to see you, well,
welcome to HMS Vengeance.
76
00:05:07,095 --> 00:05:09,840
So what I thought we'd do, is show
you around the submarine in a bit.
77
00:05:09,865 --> 00:05:12,910
But first things first, show you
where we control the submarine from,
78
00:05:12,935 --> 00:05:15,070
affectionately known
as the control room.
79
00:05:15,095 --> 00:05:16,480
Yeah, thank you very much.
80
00:05:16,505 --> 00:05:19,400
What should I call you? What should
I refer to you as?
81
00:05:19,425 --> 00:05:21,710
Most of my ship's company
just address me as Captain.
82
00:05:21,735 --> 00:05:23,990
I will call you Captain.
That will be brilliant, Rob.
83
00:05:24,015 --> 00:05:25,790
I will call you, Rob. Please do.
84
00:05:30,215 --> 00:05:31,710
So this is a control room.
85
00:05:31,735 --> 00:05:34,190
It's effectively the nerve centre
of the submarine.
86
00:05:34,215 --> 00:05:35,400
Look at this.
87
00:05:35,425 --> 00:05:37,710
On the left-hand side, this is where
all the information
88
00:05:37,735 --> 00:05:39,150
gets fed into these terminals.
89
00:05:39,175 --> 00:05:41,660
And then the team in front
of you use their knowledge,
90
00:05:41,685 --> 00:05:44,449
their wisdom and their experience
to take that information
91
00:05:44,474 --> 00:05:47,250
to draw me, effectively, a picture
of what's going outside,
92
00:05:47,275 --> 00:05:50,549
all without physically seeing it.
93
00:05:50,574 --> 00:05:52,270
It's very stable, on bored.
94
00:05:52,295 --> 00:05:54,480
I mean, I don't feel like we're
rocking round,
95
00:05:54,505 --> 00:05:56,870
we are gently moving, I seem to
remember, through the water?
96
00:05:56,895 --> 00:05:59,790
Absolutely, we're going about
walking pace at the moment.
97
00:05:59,815 --> 00:06:02,150
So we're not going to outrun
anyone at the moment.
98
00:06:02,175 --> 00:06:04,580
But she can go quite fast
if she needs to,
99
00:06:04,605 --> 00:06:07,580
but the faster we go, the more
risks of detection exists.
100
00:06:07,605 --> 00:06:10,350
The whole idea, the whole
credibility of the nuclear deterrent
101
00:06:10,375 --> 00:06:13,090
is stealth and slowly,
slowly catchy monkey.
102
00:06:13,115 --> 00:06:15,170
Battle, tile, starboard.
103
00:06:18,735 --> 00:06:21,990
At this point, all the screens
and lights and flashing lights
104
00:06:22,015 --> 00:06:25,299
going around here, it is quite
dark inside, isn't it?
105
00:06:25,324 --> 00:06:28,759
Yeah, so the only real place you're
ever going to see any daylight,
106
00:06:28,784 --> 00:06:31,429
I'm afraid, is up on the fin,
which is an icon position
107
00:06:31,454 --> 00:06:33,710
where we navigate, where
we're on the surface.
108
00:06:33,735 --> 00:06:36,350
So if we can go up there now
and I'll show you some fresh air,
109
00:06:36,375 --> 00:06:38,790
perhaps the last time
for a little while.
110
00:06:38,815 --> 00:06:41,350
That sounds like an invitation
I can't refuse.
111
00:06:41,375 --> 00:06:45,270
The conning tower is the highest
point on a submarine.
112
00:06:45,295 --> 00:06:48,710
To get there, I need to climb
the longest ladder on board.
113
00:06:49,895 --> 00:06:52,480
So I'm up for probably one
of the most unique views
114
00:06:52,505 --> 00:06:54,629
I've ever have in my life.
115
00:06:54,654 --> 00:06:56,679
But it is straight up.
116
00:06:56,704 --> 00:06:58,830
Oh, God, it's miles as well.
117
00:07:00,855 --> 00:07:02,190
Oh, knees.
118
00:07:05,784 --> 00:07:08,400
Right, Captain, you've brought
me up to what is almost
119
00:07:08,425 --> 00:07:10,580
the highest point
on the boat here.
120
00:07:10,605 --> 00:07:12,910
I mean, it's an opportunity
well, for me anyway,
121
00:07:12,935 --> 00:07:16,270
to get a bit of a glimpse
of the scale of this boat.
122
00:07:16,295 --> 00:07:17,940
It stretches back so far.
123
00:07:17,965 --> 00:07:21,220
It's hard to appreciate
just how big this boat is.
124
00:07:21,245 --> 00:07:22,790
Well, absolutely.
125
00:07:22,815 --> 00:07:25,120
She is undoubtedly akin
to an iceberg.
126
00:07:26,735 --> 00:07:29,270
She is a fantastic weapon system...
127
00:07:29,295 --> 00:07:31,940
...she's a fantastic submarine,
she's also home to us all.
128
00:07:31,965 --> 00:07:33,270
Yeah.
129
00:07:33,295 --> 00:07:35,629
She looks after us, feeds us,
keeps us watered
130
00:07:35,654 --> 00:07:37,120
and breathing safely.
131
00:07:40,065 --> 00:07:44,350
HMS Vengeance is home to over
160 submariners,
132
00:07:44,375 --> 00:07:49,350
who work endless shift patterns
of six hours on six hours off.
133
00:07:49,375 --> 00:07:52,470
But because of the secrecy
of their mission,
134
00:07:52,495 --> 00:07:55,350
few people on board will
ever know the details.
135
00:07:56,375 --> 00:07:58,759
How long do you think you're going
to be away from your family
136
00:07:58,784 --> 00:08:00,190
on this particular mission?
137
00:08:00,215 --> 00:08:01,910
I'll be away a while. A while?
138
00:08:01,935 --> 00:08:03,759
We can't be any more specific
than that.
139
00:08:03,784 --> 00:08:07,400
Not now. No. No.
OK, that's that.
140
00:08:07,425 --> 00:08:10,150
And do you know where you're going
to be heading off to?
141
00:08:10,175 --> 00:08:13,509
Somewhere down that direction,
maybe left or maybe right.
142
00:08:13,534 --> 00:08:15,830
But I know where I'm going.
143
00:08:15,855 --> 00:08:18,040
Very few people know where
I'm going.
144
00:08:18,065 --> 00:08:20,400
And that is obviously not at liberty
to be discussed,
145
00:08:20,425 --> 00:08:22,070
especially to your viewers.
146
00:08:23,454 --> 00:08:26,190
I can continue this,
this line of questioning.
147
00:08:26,215 --> 00:08:28,629
I don't think I'm going to get
any further than the generals,
148
00:08:28,654 --> 00:08:30,710
are we, Captain? Probably not.
149
00:08:30,735 --> 00:08:32,990
My team have a vague idea
where we might be.
150
00:08:33,015 --> 00:08:35,910
And over time that becomes more
and more vague.
151
00:08:35,935 --> 00:08:39,190
And that is the whole principle
of deterrent, that only a very few
152
00:08:39,215 --> 00:08:42,679
people know where it is,
therefore our security
153
00:08:42,704 --> 00:08:45,120
and our stealth is absolute.
154
00:08:48,855 --> 00:08:50,990
ET Dooley cited on the bridge.
155
00:08:51,015 --> 00:08:52,940
RADIO CHATTER
156
00:08:55,015 --> 00:08:57,350
Our interview is interrupted.
157
00:09:01,095 --> 00:09:05,710
A foreign warship has been spotted,
approaching our location.
158
00:09:05,735 --> 00:09:07,110
Where to?
159
00:09:07,135 --> 00:09:08,220
Port side.
160
00:09:10,425 --> 00:09:12,990
And it's heading right for us.
161
00:09:13,015 --> 00:09:16,910
HMS Vengeance must now get
under water... Fast.
162
00:09:19,245 --> 00:09:21,429
There's a warship heading
towards us,
163
00:09:21,454 --> 00:09:25,190
and I think we're going to dive
sooner than was originally planned.
164
00:09:25,215 --> 00:09:29,020
To get out of the way and not be
found and not be seen.
165
00:09:29,045 --> 00:09:30,820
Diving now, diving now.
166
00:09:43,900 --> 00:09:47,405
I've been given unprecedented
access to HMS Vengeance,
167
00:09:47,430 --> 00:09:51,155
one of the Royal Navy's four
Trident submarines.
168
00:09:52,669 --> 00:09:57,335
But moments after coming on board,
a foreign warship has been spotted,
169
00:09:57,360 --> 00:09:59,045
heading straight towards us.
170
00:10:20,110 --> 00:10:23,644
The executive officer is Vengeance's
second in command.
171
00:10:23,669 --> 00:10:25,925
He wants to dive the boat.
172
00:10:29,360 --> 00:10:32,405
This is real, this is genuine,
this isn't a drill, or anything.
173
00:10:32,430 --> 00:10:35,694
There is a foreign ship out there
and a risk we would be spotted?
174
00:10:35,719 --> 00:10:38,235
Absolutely, and we don't want to
be spotted on the surface.
175
00:10:38,260 --> 00:10:40,875
We want to be underneath the water
where we can track her
176
00:10:40,900 --> 00:10:42,365
rather than she tracks us.
177
00:10:42,390 --> 00:10:44,564
We're not good on the surface,
where we are good is
178
00:10:44,589 --> 00:10:47,365
underneath the waves, where we can
be quiet, where we can be stealth.
179
00:10:47,390 --> 00:10:50,085
The captain gives the order.
180
00:10:50,110 --> 00:10:52,255
Navigator, diving brief.
181
00:10:54,510 --> 00:10:56,125
Helmsman. Captain, Sir.
182
00:10:56,150 --> 00:10:57,694
Diving summary?
183
00:10:57,719 --> 00:11:00,795
Roger, diving now, diving now.
184
00:11:08,820 --> 00:11:10,875
Half turn.
185
00:11:10,900 --> 00:11:13,764
A submarine the size
of HMS Vengeance
186
00:11:13,789 --> 00:11:17,444
can take up to ten minutes
to completely submerge.
187
00:11:20,150 --> 00:11:22,514
Two down. Leaving the bubble.
188
00:11:24,469 --> 00:11:26,894
We now have one degree of bow
up, so the stern of the boat's
189
00:11:26,919 --> 00:11:28,235
beginning to sink.
190
00:11:28,260 --> 00:11:30,405
Three hands off.
191
00:11:32,230 --> 00:11:33,615
Down planing.
192
00:11:33,640 --> 00:11:35,485
Happy?
193
00:11:35,510 --> 00:11:37,875
With the foreign warship
that was nearby
194
00:11:37,900 --> 00:11:39,845
is that of concern at all?
195
00:11:39,870 --> 00:11:42,285
My objective in command of
HMS Vengeance is to remain
196
00:11:42,310 --> 00:11:44,925
undetected at all times.
197
00:11:44,950 --> 00:11:48,085
Anything that's not me is not
necessarily friendly.
198
00:11:48,110 --> 00:11:50,845
It could be a yacht, it could
be a ferry.
199
00:11:50,870 --> 00:11:52,514
It could be a warship.
200
00:11:52,539 --> 00:11:55,365
Any asset belonging to any country,
I would try and avoid it.
201
00:11:57,260 --> 00:12:00,615
West target set up on your contact,
last merchant vessel
202
00:12:00,640 --> 00:12:02,725
you have left-hand side.
203
00:12:05,230 --> 00:12:07,125
You can see...
204
00:12:07,150 --> 00:12:09,514
It's getting closer towards
us, isn't it?
205
00:12:11,950 --> 00:12:14,485
Oh, we're under.
206
00:12:14,510 --> 00:12:18,684
That's it, the Vanguard's
now underwater.
207
00:12:18,709 --> 00:12:20,875
Roger, not held sonar.
208
00:12:20,900 --> 00:12:24,485
HMS Vengeance is now fully
underwater...
209
00:12:24,510 --> 00:12:27,725
...away from the prying eyes
of the foreign warship.
210
00:12:29,070 --> 00:12:32,235
And I can get my first chance
to properly look around.
211
00:12:35,360 --> 00:12:38,725
How are you doing, all right?
Yeah, very well, thank you.
212
00:12:53,750 --> 00:12:55,365
There's four decks onboard...
213
00:12:55,390 --> 00:12:57,085
...as far as I know, anyway.
214
00:12:57,110 --> 00:12:59,285
And I'm right in the middle here.
215
00:13:02,360 --> 00:13:04,514
Hello. Hello.
216
00:13:04,539 --> 00:13:07,285
Just chilling out. Thank you.
All right. Leave you to it.
217
00:13:24,000 --> 00:13:27,615
I've not been on board very long at
all, and first impressions,
218
00:13:27,640 --> 00:13:30,684
it kind of reminds me of the
International Space Station.
219
00:13:30,709 --> 00:13:34,514
All these pipes and cables and tubes
and panels,
220
00:13:34,539 --> 00:13:38,125
all doing stuff that's obviously
deeply complex.
221
00:13:38,150 --> 00:13:42,405
But the reality is that all of this
very nearly never happened
222
00:13:42,430 --> 00:13:45,255
because just over 100 years ago,
223
00:13:45,280 --> 00:13:48,065
submarines weren't taken
seriously at all.
224
00:13:51,020 --> 00:13:54,385
In the early 20th century, Britain
had the largest Navy
225
00:13:54,410 --> 00:13:57,175
the world had ever seen.
226
00:13:57,200 --> 00:14:00,385
Hundreds of ships maintained an
empire that stretched
227
00:14:00,410 --> 00:14:02,505
from Australia to Canada.
228
00:14:08,809 --> 00:14:12,945
But the one thing the Navy had
little faith in was submarines.
229
00:14:14,729 --> 00:14:18,584
They were notoriously dangerous and
could only stay under water
230
00:14:18,609 --> 00:14:20,995
for a few minutes at a time.
231
00:14:24,050 --> 00:14:25,745
This is Holland 1...
232
00:14:27,370 --> 00:14:30,025
...the Royal Navy's first ever
submarine.
233
00:14:32,120 --> 00:14:35,425
She was built in Barrow-in-Furness
in 1901
234
00:14:35,450 --> 00:14:38,505
and measures just 20 metres
in length.
235
00:14:38,530 --> 00:14:42,664
You could fit around 150
Holland 1's inside HMS Vengeance.
236
00:14:45,370 --> 00:14:49,065
The eight crew could barely stand
and would be enveloped
237
00:14:49,090 --> 00:14:52,784
by exhaust fumes from the petrol
engine.
238
00:14:52,809 --> 00:14:56,505
They couldn't stay under water for
long or they'd suffocate
239
00:14:56,530 --> 00:14:59,425
and the risk of an explosion
was high.
240
00:15:00,970 --> 00:15:05,425
The Royal Navy decided that compared
with their massive surface ships,
241
00:15:05,450 --> 00:15:08,175
submarines weren't worth the effort.
242
00:15:11,660 --> 00:15:14,425
But other navies were
less sceptical.
243
00:15:14,450 --> 00:15:19,025
Germany believed that stealthy subs
could play a pivotal part in war.
244
00:15:20,660 --> 00:15:24,385
They called their submarines
undersea boats,
245
00:15:24,410 --> 00:15:26,584
U - boats.
246
00:15:26,609 --> 00:15:31,315
They were faster, quieter and safer
than anything Britain had tried.
247
00:15:32,500 --> 00:15:37,275
Two weeks into the First World War,
the Germans put them to use.
248
00:15:37,300 --> 00:15:42,605
A loan U-boat stalked British ships
into the Firth of Forth.
249
00:15:42,630 --> 00:15:45,884
It launched a single torpedo at a
British ship,
250
00:15:45,909 --> 00:15:50,035
sinking her and killing over
250 of her crew.
251
00:15:53,090 --> 00:15:57,884
Suddenly, the submarine had become a
genuine weapon of war.
252
00:16:01,340 --> 00:16:05,395
HMS Vengeance has the Spearfish
torpedo system.
253
00:16:05,420 --> 00:16:08,634
With a range some 20 times greater
than the one that caused
254
00:16:08,659 --> 00:16:12,424
so much destruction over
100 years ago,
255
00:16:12,449 --> 00:16:16,195
and with much more sophisticated
technology.
256
00:16:16,220 --> 00:16:18,554
Tell me a bit more about these
torpedoes.
257
00:16:18,579 --> 00:16:20,355
What would you use them for?
258
00:16:20,380 --> 00:16:23,395
So, we'd use these against
submarine targets
259
00:16:23,420 --> 00:16:26,065
and ship surface targets.
260
00:16:26,090 --> 00:16:29,525
They're designed so that they can be
guided from a submarine.
261
00:16:29,550 --> 00:16:32,424
In layman's terms, how big a bang
would these torpedoes make?
262
00:16:32,449 --> 00:16:34,835
Oh, a big enough bang
to sink a ship.
263
00:16:34,860 --> 00:16:38,145
So, there's about 300 kg of
explosives in it.
264
00:16:38,170 --> 00:16:42,674
OK, so that is enough to sink, what,
even some of the biggest warships?
265
00:16:42,699 --> 00:16:45,674
Uh, yeah. There's two different
methods that we can use for that.
266
00:16:45,699 --> 00:16:47,395
Go on, then, what are they?
267
00:16:47,420 --> 00:16:50,595
So, one is where we would...
It would just basically slam
268
00:16:50,620 --> 00:16:53,705
into the side of a target and the
other is where it would
269
00:16:53,730 --> 00:16:56,705
explode underneath and it would
cause an air bubble,
270
00:16:56,730 --> 00:17:00,395
break the back of the ship and,
basically, it would snap it in half.
271
00:17:00,420 --> 00:17:03,035
It would sink.
272
00:17:03,060 --> 00:17:06,345
But torpedoes are only one of the
reasons modern submarines
273
00:17:06,370 --> 00:17:08,884
are now so powerful.
274
00:17:18,370 --> 00:17:23,915
Their ability to see underwater has
revolutionised their effectiveness.
275
00:17:23,940 --> 00:17:26,035
It's called sonar.
276
00:17:27,500 --> 00:17:30,424
Now, what is sonar and
how does it work?
277
00:17:30,449 --> 00:17:34,115
OK, sonar is basically the eyes and
ears of the submarine.
278
00:17:34,140 --> 00:17:37,035
It works by hydrophones that set up
in various locations
279
00:17:37,060 --> 00:17:40,995
around the submarine and we are
listening to a vessel -
280
00:17:41,020 --> 00:17:43,315
a merchant vessel, a fishing vessel
warships, submarine
281
00:17:43,340 --> 00:17:45,065
or whatever it is out there.
282
00:17:45,090 --> 00:17:48,345
And that noise is transmitting from
that vessel onto our hydrophones,
283
00:17:48,370 --> 00:17:50,315
flitting onto our screen.
284
00:17:50,340 --> 00:17:52,525
How do you identify what that
soundis?
285
00:17:52,550 --> 00:17:54,955
A merchant vessel, you feel the
diesel engine rubs in on it
286
00:17:54,980 --> 00:17:57,345
and you'll sometimes be able to hear
the propeller moving.
287
00:17:57,370 --> 00:17:59,754
When it comes to warships,
imagine licking your finger
288
00:17:59,779 --> 00:18:02,345
and rubbing it round the edge of a
wineglass, that whiney sound.
289
00:18:02,370 --> 00:18:05,035
Oh, a much higher pitch?
Yeah, a real high-pitch sound, yeah.
290
00:18:05,060 --> 00:18:07,915
And how far away can you actually
listen?
291
00:18:07,940 --> 00:18:12,195
How far away can you build up a
picture of what else is out there?
292
00:18:12,220 --> 00:18:14,065
It depends on the body of water
you're in.
293
00:18:14,090 --> 00:18:17,705
If you're in deep water, it can
certainly go to 100,000 yards.
294
00:18:17,730 --> 00:18:20,475
Up to 100,000 yards?
Yeah, about 50 nautical miles.
295
00:18:20,500 --> 00:18:22,345
WQW!
296
00:18:22,370 --> 00:18:25,955
The sonar system on HMS Vengeance
is a direct descendant
297
00:18:25,980 --> 00:18:29,595
of the technology that helped
Britain in her darkest hour...
298
00:18:31,060 --> 00:18:33,145
...The Battle of the Atlantic.
299
00:18:35,659 --> 00:18:39,195
In 1939, as World War ll started,
300
00:18:39,220 --> 00:18:41,634
Britain depended on its
Merchant Navy
301
00:18:41,659 --> 00:18:44,345
to bring supplies and ammunition
from abroad.
302
00:18:47,040 --> 00:18:50,965
It was all controlled from this
secret location,
303
00:18:50,990 --> 00:18:53,795
Western Approaches in Liverpool,
304
00:18:53,820 --> 00:18:58,125
and it's here that many believe
World War ll was actually won.
305
00:19:01,310 --> 00:19:05,125
This room was the command centre
which coordinated the trade ships
306
00:19:05,150 --> 00:19:07,285
bringing goods into the UK.
307
00:19:11,459 --> 00:19:15,644
Hitler realised those ships were
vulnerable to submarines.
308
00:19:17,310 --> 00:19:21,245
He ordered his U-boats to attack
with devastating results.
309
00:19:24,430 --> 00:19:27,535
Hundreds of British ships were sunk
310
00:19:27,560 --> 00:19:31,045
and it seemed like Germany might
actually win the war.
311
00:19:34,630 --> 00:19:38,434
Winston Churchill said that Germany
U-boats were the only things
312
00:19:38,459 --> 00:19:40,965
that really frightened him
during the war.
313
00:19:47,459 --> 00:19:52,434
But it was British ingenuity that
helped turn the tide.
314
00:19:52,459 --> 00:19:56,814
By 1943, a forward step in
underwater technology
315
00:19:56,839 --> 00:20:01,605
meant the Royal Navy could track and
destroy the U-boats more frequently.
316
00:20:03,459 --> 00:20:06,634
Today, we know this technology
as sonar.
317
00:20:15,870 --> 00:20:19,285
Erm, right, this in me here, is it?
Yeah, that's you. Yeah, put them on.
318
00:20:19,310 --> 00:20:23,485
I'm intrigued to listen to the
sounds of sonar for myself.
319
00:20:23,510 --> 00:20:25,355
See what I can find, then.
320
00:20:30,270 --> 00:20:32,605
So, what you're listening to now
is a merchant vessel.
321
00:20:32,630 --> 00:20:34,175
I'm listening to a merchant vessel?
322
00:20:34,200 --> 00:20:36,715
That's a merchant vessel right now.
It just sounds like fuzz.
323
00:20:36,740 --> 00:20:39,175
Yeah, to the untrained ear it will
probably sounds like fuzz
324
00:20:39,200 --> 00:20:41,325
but there's a bit of diesel behind
it, can hear a bit of
325
00:20:41,350 --> 00:20:42,995
diesel from the engine.
326
00:20:43,020 --> 00:20:44,455
Hang on.
327
00:20:45,990 --> 00:20:49,405
I'm really trying to hear
diesel in that.
328
00:20:49,430 --> 00:20:51,125
That's different.
329
00:20:52,459 --> 00:20:55,205
It definitely changes as I scroll
through here.
330
00:20:55,230 --> 00:20:57,434
That sounds a lot heavier.
331
00:20:57,459 --> 00:20:59,325
Yeah, I think what you're
listening to there's
332
00:20:59,350 --> 00:21:01,205
like a large merchant vessel.
333
00:21:01,230 --> 00:21:03,564
If you listen really carefully,
you should be able to get
334
00:21:03,589 --> 00:21:05,485
a revolution spinning count,
if you listen.
335
00:21:05,510 --> 00:21:08,075
Is it kind of... Like a rhythmic
beat, yeah, that's it.
336
00:21:10,909 --> 00:21:12,634
This other one I've found here,
then,
337
00:21:12,659 --> 00:21:15,355
sounds a lot higher pitched, almost.
338
00:21:15,380 --> 00:21:17,564
Let me see... Let me hear with that
one.
339
00:21:20,659 --> 00:21:22,684
Yeah, that was it.
That's higher pitched.
340
00:21:22,709 --> 00:21:25,434
That sounds like it's going, like
their revolution is a lot faster.
341
00:21:25,459 --> 00:21:27,634
It'll be a small merchant vessel,
a fishing vessel.
342
00:21:27,659 --> 00:21:29,965
You can hear it's moving much
quicker through the water.
343
00:21:29,990 --> 00:21:32,605
OK, yeah, there's something in
there. Something behind it, yeah.
344
00:21:32,630 --> 00:21:34,635
Something that's identifiable.
345
00:21:34,660 --> 00:21:39,005
But, for me, it's just a continuous
noise.
346
00:21:39,030 --> 00:21:41,644
It is for everyone until they start
doing the training properly.
347
00:21:41,669 --> 00:21:44,725
The younger lads would be able to
crossfire this, no problem.
348
00:21:44,750 --> 00:21:48,215
So, this is my first time sat at any
kind of sonar system like this.
349
00:21:48,240 --> 00:21:50,444
How am I doing, Dale, how's...?
350
00:21:50,469 --> 00:21:54,005
You haven't done bad, Rob, but I
wouldn't give up your day job.
351
00:21:54,030 --> 00:21:57,535
HMS Vengeance needs one of the most
powerful sonar systems
352
00:21:57,560 --> 00:22:02,415
in the world because of what this
submarine carries inside it.
353
00:22:07,750 --> 00:22:11,694
I can't quite get my head around
where I'm stood -
354
00:22:11,719 --> 00:22:14,365
right in the heart of HMS Vengeance.
355
00:22:14,390 --> 00:22:19,215
These are the missile tubes that
house Trident nuclear missiles.
356
00:22:20,469 --> 00:22:23,185
In here are nuclear warheads.
357
00:22:25,000 --> 00:22:28,574
And it's surreal to stand so close
to something so terrifying...
358
00:22:30,210 --> 00:22:32,774
...something so deadly.
359
00:22:43,978 --> 00:22:48,752
I'm on board the Royal Navy's
HMS Vengeance Submarine,
360
00:22:48,777 --> 00:22:51,833
which is carrying Trident
nuclear missiles.
361
00:22:54,058 --> 00:22:58,983
To understand how we got them in the
UK and why they're on board,
362
00:22:59,008 --> 00:23:01,672
we need to go back 50 years.
363
00:23:11,058 --> 00:23:16,033
By the early '60s, Britain was
eager to become a nuclear power.
364
00:23:16,058 --> 00:23:19,313
Prime Minister Harold Macmillan
flew to the Bahamas
365
00:23:19,338 --> 00:23:21,903
to convince President
John F. Kennedy
366
00:23:21,928 --> 00:23:24,593
to share their nuclear missile
secrets.
367
00:23:26,058 --> 00:23:30,183
The deal they struck became known as
the Polaris Sales Agreement.
368
00:23:32,817 --> 00:23:35,953
Britain would be given Polaris
nuclear missiles
369
00:23:35,978 --> 00:23:40,113
and the Americans would gain access
to several Scottish lochs.
370
00:23:44,058 --> 00:23:46,903
But a new challenge immediately
arose.
371
00:23:46,928 --> 00:23:51,153
We needed a place to house and
launch these new nuclear missiles.
372
00:23:52,817 --> 00:23:56,792
It was decided that the only truly
secure place
373
00:23:56,817 --> 00:23:59,872
was deep at sea on a submarine.
374
00:24:02,928 --> 00:24:06,833
50 years ago in 1969, the British
Submarine Service
375
00:24:06,858 --> 00:24:09,752
began carrying nuclear missiles,
376
00:24:09,777 --> 00:24:13,113
becoming the UK's strategic nuclear
deterrent.
377
00:24:14,498 --> 00:24:19,183
HMS Vengeance is the latest
generation of these submarines.
378
00:24:19,208 --> 00:24:22,752
The missiles she carries are
called Trident.
379
00:24:22,777 --> 00:24:26,542
They're the most powerful weapon
Britain has ever had.
380
00:24:35,208 --> 00:24:36,953
These are the Trident nuclear
missiles?
381
00:24:36,978 --> 00:24:38,752
Trident ll D5 nuclear missiles.
382
00:24:38,777 --> 00:24:41,183
Right around us? Yeah.
383
00:24:41,208 --> 00:24:44,513
The weapons engineering officer is
responsible for looking after
384
00:24:44,538 --> 00:24:47,433
Tridents on HMS Vengeance.
385
00:24:47,458 --> 00:24:51,033
How many missiles do we have on
board here, then?
386
00:24:51,058 --> 00:24:52,983
On Vengeance?
387
00:24:53,008 --> 00:24:54,872
Uh, I couldn't tell you that.
OK.
388
00:24:54,897 --> 00:24:57,823
Up to 16. Up to 16?
Yeah.
389
00:24:57,848 --> 00:25:00,903
Do we know how many nuclear warheads
we have on board?
390
00:25:00,928 --> 00:25:04,263
So, we can have up to 40 warheads on
board at one time.
391
00:25:04,288 --> 00:25:07,723
When it comes to these missiles,
is there any way
392
00:25:07,748 --> 00:25:10,233
of describing the amount of
firepower that that is?
393
00:25:10,258 --> 00:25:12,542
I don't know, it's just hard to get
that as a concept.
394
00:25:12,567 --> 00:25:15,153
So, Nagasaki and Hiroshima, if you
think of those... Yeah.
395
00:25:15,178 --> 00:25:18,343
...there's more than both of them put
together around us now. Wow.
396
00:25:20,458 --> 00:25:22,792
Do you ever get used to the fact
you're living and working
397
00:25:22,817 --> 00:25:27,033
around the most deadly weapons
ever created?
398
00:25:27,058 --> 00:25:29,542
That's quite sobering for me
stood here.
399
00:25:29,567 --> 00:25:31,542
I don't know how that is for you.
400
00:25:31,567 --> 00:25:33,903
Yeah, it's...
401
00:25:33,928 --> 00:25:35,903
Yeah, it is.
402
00:25:40,538 --> 00:25:43,823
If he came to it, then, once you
actually press fire,
403
00:25:43,848 --> 00:25:46,113
what actually happens with these
missiles?
404
00:25:46,138 --> 00:25:48,542
How do they work?
405
00:25:48,567 --> 00:25:51,983
So, once the trigger's pressed,
the hatch will open.
406
00:25:52,008 --> 00:25:56,073
Once that opens the missile launches
up into space,
407
00:25:56,098 --> 00:26:00,033
then the bombs, so to speak, will
follow out to the targets.
408
00:26:02,458 --> 00:26:04,622
You are part of that process,
are you, that firing?
409
00:26:04,647 --> 00:26:06,363
So, I'm the end of the firing
chain, yes.
410
00:26:06,388 --> 00:26:08,542
Ultimately, on the end of the
trigger,
411
00:26:08,567 --> 00:26:10,953
starts with the Prime Minister,
finishes with me.
412
00:26:14,817 --> 00:26:19,033
The nuclear deterrent must always be
ready to fire on the orders
413
00:26:19,058 --> 00:26:22,033
of the Prime Minister and at a
moment's notice.
414
00:26:25,258 --> 00:26:26,792
ALARM BEEPS
415
00:26:28,008 --> 00:26:29,903
Panel stations, panel stations.
416
00:26:29,928 --> 00:26:32,183
Panel stations, missile training,
on our guidance
417
00:26:32,208 --> 00:26:34,433
with the launch...
418
00:26:35,777 --> 00:26:38,463
The crew test the nuclear missile
firing procedure
419
00:26:38,488 --> 00:26:40,463
on a regular basis.
420
00:26:42,138 --> 00:26:45,313
All positions secure from returning
the periscope down.
421
00:26:47,058 --> 00:26:50,953
Search condition one, scuba training
with our guidance with launcher.
422
00:26:50,978 --> 00:26:54,872
Captain Darren Mason is authorised
to test fire Trident.
423
00:26:56,058 --> 00:26:58,073
Rogen
424
00:26:58,098 --> 00:26:59,983
What is actually going on here?
425
00:27:00,008 --> 00:27:05,433
OK, so for this, we're simulating
a weapon system readiness test,
426
00:27:05,458 --> 00:27:08,792
which is proving to the outside
authorities that the weapon system
427
00:27:08,817 --> 00:27:11,263
is incredible for its task, which
we're required to do.
428
00:27:11,288 --> 00:27:13,463
So, the weapon system, we're talking
about our...?
429
00:27:13,488 --> 00:27:15,313
Ballistic missile system,
the deterrent.
430
00:27:15,338 --> 00:27:16,903
Our nuclear deterrent?
431
00:27:16,928 --> 00:27:19,433
And by doing so, we've got to battle
stations missile,
432
00:27:19,458 --> 00:27:22,872
which was the general alarm,
the angry doorbell, as we call it.
433
00:27:22,897 --> 00:27:25,073
Why is it important to do
this exercise?
434
00:27:25,098 --> 00:27:29,953
Well, if we didn't do the exercise,
we wouldn't know it worked.
435
00:27:29,978 --> 00:27:32,343
CODED RADIO COMMAND
436
00:27:36,618 --> 00:27:39,153
The encrypted order to test fire is
transmitted
437
00:27:39,178 --> 00:27:43,513
to HMS Vengeance and given to two
of her most senior officers.
438
00:27:45,567 --> 00:27:50,033
The order is printed and carried to
the control room in plain sight,
439
00:27:50,058 --> 00:27:54,353
so there's no possibility it can
be interfered with.
440
00:27:54,378 --> 00:27:59,183
Then, behind a screen,
its contents are decoded.
441
00:28:08,738 --> 00:28:10,672
2.5.
442
00:28:10,697 --> 00:28:12,903
So, the doctor's just give me the
latest update
443
00:28:12,928 --> 00:28:15,792
of the target packages that are in
the computer.
444
00:28:15,817 --> 00:28:18,183
I have just been given the assurance
that my understanding
445
00:28:18,208 --> 00:28:20,433
of what's going on in the
submarine's computer system,
446
00:28:20,458 --> 00:28:22,393
in my little black book, which,
unfortunately,
447
00:28:22,418 --> 00:28:24,542
you can't look at, is exactly the
same as being held
448
00:28:24,567 --> 00:28:26,073
in the weapon system.
449
00:28:26,098 --> 00:28:28,672
So, by comparing and contrasting
this and my black book,
450
00:28:28,697 --> 00:28:31,103
I know categorically the weapon
system is going to do exactly
451
00:28:31,128 --> 00:28:33,033
what I expect it to do.
452
00:28:34,288 --> 00:28:35,953
So four by three metres.
453
00:28:37,378 --> 00:28:39,153
Come on.
454
00:28:40,458 --> 00:28:42,033
Come on at 1SQ.
455
00:28:43,338 --> 00:28:44,983
Shipping 1SQ.
456
00:28:47,488 --> 00:28:50,183
So, the submarine's now been brought
up to a certain launch depth,
457
00:28:50,208 --> 00:28:52,672
and been slowed down, we're now,
ultimately, stopped. Mm.
458
00:28:52,697 --> 00:28:56,033
This 13,000 tonne submarine is
physically stopped in the water,
459
00:28:56,058 --> 00:29:00,033
hovering, which means at 1840
on this clock, on the top,
460
00:29:00,058 --> 00:29:03,353
we will be able to be ready,
in all respects,
461
00:29:03,378 --> 00:29:05,263
to simulate a strike.
462
00:29:05,288 --> 00:29:07,463
And for the purposes of this
exercise,
463
00:29:07,488 --> 00:29:09,073
you will give that command,
will you?
464
00:29:09,098 --> 00:29:10,672
I will give that command.
465
00:29:10,697 --> 00:29:14,033
With the final checks made,
the weapons engineering officer
466
00:29:14,058 --> 00:29:16,353
can pull the test trigger.
467
00:29:16,378 --> 00:29:19,002
Weapons con. My permission to fire
at your 1SQ report.
468
00:29:19,027 --> 00:29:20,823
Con weapons.
469
00:29:20,848 --> 00:29:23,433
Weapon systems ready for
strategic launch.
470
00:29:23,458 --> 00:29:24,992
Weapons con.
471
00:29:28,058 --> 00:29:30,183
Launching condition
1SQ for strategic launch.
472
00:29:30,208 --> 00:29:31,713
Launch of weapons. Roger.
473
00:29:31,738 --> 00:29:34,713
Weapons supervisor, request you...
474
00:29:34,738 --> 00:29:37,463
If it came to it, then, have you
thought through
475
00:29:37,488 --> 00:29:42,263
how you might feel if you had to
pull that trigger, fire the trigger?
476
00:29:43,647 --> 00:29:46,353
That's my job, I've worked long time
to get here,
477
00:29:46,378 --> 00:29:49,353
and if I wasn't going to do what
I was ordered,
478
00:29:49,378 --> 00:29:51,313
then I wouldn't be here.
479
00:29:55,378 --> 00:29:57,033
Ten seconds to launch.
480
00:29:57,058 --> 00:29:59,823
Five, four, three,
481
00:29:59,848 --> 00:30:02,433
two, one...
482
00:30:02,458 --> 00:30:04,313
Bombs away.
483
00:30:07,897 --> 00:30:10,263
Happy with that?
484
00:30:10,288 --> 00:30:11,953
Away.
485
00:30:11,978 --> 00:30:13,593
Permission to fire removed.
486
00:30:13,618 --> 00:30:15,713
...outside.
487
00:30:18,817 --> 00:30:20,992
The test is now complete.
488
00:30:21,017 --> 00:30:24,233
They're coming back down to
a safe depth
489
00:30:24,258 --> 00:30:26,283
and, ultimately, carrying
on with our patrol.
490
00:30:26,308 --> 00:30:30,103
When would you know in the case that
this was a real scenario?
491
00:30:30,128 --> 00:30:31,713
God forbid.
492
00:30:31,738 --> 00:30:35,713
When would you know the time to
fire, to give the order to fire?
493
00:30:35,738 --> 00:30:37,233
That's a very good question.
494
00:30:37,258 --> 00:30:39,153
So, these things don't just happen.
Yeah.
495
00:30:39,178 --> 00:30:42,313
There would be a significant
escalation or deterioration
496
00:30:42,338 --> 00:30:44,903
of political instability. Yep.
497
00:30:44,928 --> 00:30:48,823
We would notice that extra units of
the Royal Navy were at sea,
498
00:30:48,848 --> 00:30:51,672
there would be a whole narrative of
the story developing.
499
00:30:51,697 --> 00:30:54,713
I would expect that I would be
anticipating that the order
500
00:30:54,738 --> 00:30:56,742
to launch might be occurring.
501
00:30:56,767 --> 00:31:00,153
With it comes this enormous
responsibility.
502
00:31:00,178 --> 00:31:02,903
How well does that sit
with you as...
503
00:31:02,928 --> 00:31:04,953
...as a person?
504
00:31:04,978 --> 00:31:08,593
Urn, it's not a conversation I
routinely have with people. Mm.
505
00:31:08,618 --> 00:31:11,383
It is a job I am expected to do.
506
00:31:11,408 --> 00:31:14,073
I'm trusted to hold those keys.
507
00:31:14,098 --> 00:31:15,903
I'm just to deliver that capability.
508
00:31:15,928 --> 00:31:18,433
But have absolute confidence that
when I'm tasked to deliver
509
00:31:18,458 --> 00:31:22,463
that effect, that decision is made
in good faith by the right people,
510
00:31:22,488 --> 00:31:25,313
with the right intelligence,
with the right outcome in mind.
511
00:31:25,338 --> 00:31:28,383
I am simply the tool that delivers
that capability.
512
00:31:34,538 --> 00:31:40,263
Before today, I've never fully
contemplated the end of the world,
513
00:31:40,288 --> 00:31:44,953
but, actually, if it were to happen,
it would play out almost exactly
514
00:31:44,978 --> 00:31:47,153
as I've just seen.
515
00:31:47,178 --> 00:31:50,742
Surrounded as I am by these weapons
of mass destruction,
516
00:31:50,767 --> 00:31:54,463
it would fall to the people I've met
on here to carry out
517
00:31:54,488 --> 00:31:57,633
this most horrific of orders.
518
00:31:57,658 --> 00:32:01,383
That's what resonates with me
and what I find
519
00:32:01,408 --> 00:32:03,792
difficult to reconcile.
520
00:32:03,817 --> 00:32:07,073
That the crew on this sub help
keep us all safe
521
00:32:07,098 --> 00:32:11,313
every single day, but they also
hold this terrifying,
522
00:32:11,338 --> 00:32:15,233
destructive power and unimaginable
responsibility.
523
00:32:16,658 --> 00:32:20,263
For 50 years, they've patrolled in
silence.
524
00:32:20,288 --> 00:32:23,903
But it would only take one day
and one act
525
00:32:23,928 --> 00:32:27,103
to end life on Earth as we know it.
526
00:32:34,338 --> 00:32:36,542
ALARM BEEPS
527
00:32:38,178 --> 00:32:40,463
There's no rest for the crew today.
528
00:32:42,618 --> 00:32:45,253
On the back of the Trident firing
drill,
529
00:32:45,278 --> 00:32:47,012
the fire alarm sounds.
530
00:32:47,037 --> 00:32:49,792
ALARM CONTINUES BEEPING
531
00:32:51,978 --> 00:32:53,872
A fire can cripple a submarine...
532
00:32:55,738 --> 00:32:58,073
...and burn up precious oxygen.
533
00:32:59,928 --> 00:33:02,023
ALARM CONTINUES
534
00:33:09,848 --> 00:33:11,733
Get that down.
535
00:33:11,758 --> 00:33:13,453
ALARM CONTINUES
536
00:33:14,998 --> 00:33:17,713
MUFFLED TANNOY ANNOUNCEMENT:
The fire's now...
537
00:33:17,738 --> 00:33:19,992
The submarine is safe.
538
00:33:20,017 --> 00:33:22,872
Fortunately, this was a drill.
539
00:33:24,658 --> 00:33:28,542
...but the crew's response is
reviewed as if it were real.
540
00:33:28,567 --> 00:33:32,103
When the fire pipe came out, the
noise level starts to increase.
541
00:33:32,128 --> 00:33:34,953
But considering the amount of people
in here right now,
542
00:33:34,978 --> 00:33:37,383
the noise levels very quickly
dropped back down again
543
00:33:37,408 --> 00:33:40,513
to a manageable level and the team
effort in here,
544
00:33:40,538 --> 00:33:43,353
you were backing each other up,
which is good to see.
545
00:33:43,378 --> 00:33:46,672
The crew did well
but it wasn't perfect.
546
00:33:46,697 --> 00:33:50,273
Safety must always be the captain's
primary concern.
547
00:33:50,298 --> 00:33:53,023
I worry about the material state
of the submarine.
548
00:33:53,048 --> 00:33:55,593
I worry about the wellbeing of my
ship's company.
549
00:33:55,618 --> 00:33:58,183
I have 167 people who look to me
to give them
550
00:33:58,208 --> 00:34:00,713
the assurance and safety
and that's my job.
551
00:34:06,048 --> 00:34:09,103
Just gone nine o'clock in the
evening and I have to keep
552
00:34:09,128 --> 00:34:11,713
looking at my watch because there's
no other means to tell you,
553
00:34:11,738 --> 00:34:13,672
there's no daylight.
554
00:34:13,697 --> 00:34:16,073
It's just such an alien environment.
555
00:34:17,738 --> 00:34:21,183
Well, it's been an insight
into what happens on board.
556
00:34:21,208 --> 00:34:25,023
I'm absolutely knackered just from
taking everything in,
557
00:34:25,048 --> 00:34:27,792
but I'm quite looking forward to
waking up in the morning
558
00:34:27,817 --> 00:34:29,973
because there's so much more
about this sub
559
00:34:29,998 --> 00:34:32,733
that I still want to understand.
560
00:34:32,758 --> 00:34:33,762
ALARM BEEPS
561
00:34:35,428 --> 00:34:37,682
Moments after we finished
filming,
562
00:34:37,707 --> 00:34:39,973
the general alarm sounds again.
563
00:34:39,998 --> 00:34:42,403
But this time, it's for real.
564
00:34:44,068 --> 00:34:47,093
There's a leak in the engine room,
an area of the boat that's
565
00:34:47,118 --> 00:34:49,733
off limits to our cameras.
566
00:35:08,707 --> 00:35:11,533
As the leak is frantically being
plugged,
567
00:35:11,558 --> 00:35:14,533
I stumble across the man
who discovered it.
568
00:35:14,558 --> 00:35:16,932
He's been moved to a safe
compartment.
569
00:35:16,957 --> 00:35:19,293
What did you see? How did you...?
570
00:35:19,318 --> 00:35:21,253
A spray of hydraulic oiL
571
00:35:21,278 --> 00:35:23,453
You could smell it in the air before
you got there.
572
00:35:23,478 --> 00:35:25,762
Quite intense as soon as you
got down by the shaft,
573
00:35:25,787 --> 00:35:27,733
so you knew it was coming from
there.
574
00:35:27,758 --> 00:35:31,613
So ljust grabbed a rag and
dived in and stopped
575
00:35:31,638 --> 00:35:34,123
the hydraulic turning into a mist,
because that's when it's at
576
00:35:34,148 --> 00:35:36,043
its most dangerous.
577
00:35:36,068 --> 00:35:37,843
So it was all over me,
over my hair,
578
00:35:37,868 --> 00:35:40,012
and it you could just taste it in
the atmosphere.
579
00:35:40,037 --> 00:35:41,932
Are you all right? Yeah, yeah, good.
580
00:35:41,957 --> 00:35:44,333
My shoulder's a bit sore.
Why's that?
581
00:35:44,358 --> 00:35:47,812
I think I cracked it as I went
in for the leak, like.
582
00:35:47,837 --> 00:35:49,892
Wow, listen, mate...
583
00:35:49,917 --> 00:35:52,733
Look, you go and make sure you get
yourself sorted out. Yeah, I will.
584
00:35:52,758 --> 00:35:55,373
The engineer's quick thinking
stopped the leak
585
00:35:55,398 --> 00:35:57,583
from turning into a fire.
586
00:36:00,608 --> 00:36:03,483
But the boat's hydraulics are now
compromised.
587
00:36:03,508 --> 00:36:05,373
Well, your worst case, you've got
everything
588
00:36:05,398 --> 00:36:07,733
on the one hydraulic system.
589
00:36:14,998 --> 00:36:18,012
If the crew can't find a solution
underwater,
590
00:36:18,037 --> 00:36:20,093
they'll have to return to port,
591
00:36:20,118 --> 00:36:23,203
making them late for their nuclear
deterrent patrol.
592
00:36:26,957 --> 00:36:30,043
Fixing this problem is now top
priority.
593
00:36:46,638 --> 00:36:48,173
ALARM BEEPS
594
00:36:52,278 --> 00:36:56,493
HMS Vengeance is at emergency
stations in the middle of the night.
595
00:37:02,917 --> 00:37:06,493
It's suffered a hydraulic leak
that's just been plugged,
596
00:37:33,468 --> 00:37:36,563
Senior officers must decide
what to do.
597
00:37:36,588 --> 00:37:39,493
Either they trust the quick fix
they've just done to hold
598
00:37:39,518 --> 00:37:41,923
for the next few months at sea,
599
00:37:41,948 --> 00:37:44,613
or delay their mission and head
home.
600
00:38:03,468 --> 00:38:04,972
So, what happens now?
601
00:38:04,997 --> 00:38:07,563
We've briefed the captain and now
there's a plan going in place,
602
00:38:07,588 --> 00:38:10,283
which means that we revert some of
our systems,
603
00:38:10,308 --> 00:38:13,203
albeit to an abnormal line up,
it's still a safe line up
604
00:38:13,228 --> 00:38:16,083
and the submarine will still work
as it normally would.
605
00:38:16,108 --> 00:38:20,563
Which means that you can continue
on as was planned with the sub?
606
00:38:20,588 --> 00:38:22,772
Just with backup systems?
Absolutely, yeah.
607
00:38:22,797 --> 00:38:25,283
A backup system for the main
system and there's a backup system
608
00:38:25,308 --> 00:38:27,693
for the backup system, it's all
built on an emergency mode.
609
00:38:27,718 --> 00:38:29,363
So it's just about picking
the right one.
610
00:38:29,388 --> 00:38:31,613
There's never a dull moment, is
there? There is not, no.
611
00:38:31,638 --> 00:38:34,283
I did have my head down at that
stage, as well, I was fast asleep,
612
00:38:34,308 --> 00:38:36,203
and it gives you a bit of a fright.
613
00:38:36,228 --> 00:38:38,912
I can share that, likewise!
Yeah.
614
00:38:42,588 --> 00:38:45,642
The decision has been made
to continue the mission.
615
00:38:50,278 --> 00:38:53,053
But the following day, there's some
bad news for the engineer
616
00:38:53,078 --> 00:38:55,173
who found the leak.
617
00:39:45,588 --> 00:39:48,203
The engineer's quick response
prevented a fire
618
00:39:48,228 --> 00:39:50,972
in HMS Vengeance's engine room.
619
00:39:50,997 --> 00:39:55,426
But his injury means his time on
board is now over
620
00:39:55,451 --> 00:39:58,129
and my four clays and nights
on the submarine
621
00:39:58,154 --> 00:40:01,279
are also coming to an end.
622
00:40:01,304 --> 00:40:04,658
The submarine's just surfaced, which
means that I can take a peek
623
00:40:04,683 --> 00:40:06,559
with the periscope.
624
00:40:06,584 --> 00:40:09,279
There's a horizon there, which is
something I've not seen
625
00:40:09,304 --> 00:40:11,279
for a fair while.
626
00:40:13,274 --> 00:40:16,449
It's actually quite a personal
moment, though,
627
00:40:16,474 --> 00:40:19,638
because I'm very aware that as my
visit here on the sub
628
00:40:19,663 --> 00:40:24,559
draws to a close, the crew's mission
is just beginning
629
00:40:24,584 --> 00:40:28,729
and this is close to home as they're
going to get for a good few months.
630
00:40:32,044 --> 00:40:36,279
Once I leave, HMS Vengeance will
head out on patrol,
631
00:40:36,304 --> 00:40:39,249
along with her nuclear deterrent.
632
00:40:39,274 --> 00:40:43,609
For the crew, their mission has only
just started.
633
00:40:45,274 --> 00:40:50,088
To spend weeks, months, maybe,
out at sea,
634
00:40:50,113 --> 00:40:54,888
away from normal life, away from
family and friends and loved ones,
635
00:40:54,913 --> 00:40:57,049
I think I'd find really, really
difficult.
636
00:40:57,074 --> 00:40:58,549
Really, really difficult.
637
00:40:58,574 --> 00:41:00,549
It is the people that make the
submarine,
638
00:41:00,574 --> 00:41:02,559
as the family make the submariner.
639
00:41:02,584 --> 00:41:05,329
Driving away from the house,
I would lie to you if I didn't
640
00:41:05,354 --> 00:41:08,049
stop the car and I don't have to
think about it. Mm.
641
00:41:08,074 --> 00:41:11,049
And a few leaky eyeball moments and
then, unfortunately,
642
00:41:11,074 --> 00:41:14,838
you have to accept your divinity
and move on.
643
00:41:19,104 --> 00:41:22,999
The weekly highlight for everyone on
board will now be a short message
644
00:41:23,024 --> 00:41:25,529
from loved ones at home.
645
00:41:25,554 --> 00:41:28,999
Even that's censored and there's no
means to reply.
646
00:41:30,663 --> 00:41:33,249
It's certainly not a life
I could lead.
647
00:41:36,584 --> 00:41:40,249
For over 50 years, Royal Navy
submariners
648
00:41:40,274 --> 00:41:45,449
have secretly kept our nuclear
deterrent at permanent readiness,
649
00:41:45,474 --> 00:41:47,559
but these boats are now ageing.
650
00:41:49,194 --> 00:41:52,768
So, whatever we might feel about the
nuclear deterrent,
651
00:41:52,793 --> 00:41:55,379
its future is already decided.
652
00:41:57,094 --> 00:41:59,479
Will there be a next 50 years of
at sea deterrent for the UK,
653
00:41:59,504 --> 00:42:01,169
do you think?
654
00:42:01,194 --> 00:42:06,279
Well, I'm going to say,
perversely, sadly,
655
00:42:06,304 --> 00:42:08,169
we are planning that.
656
00:42:08,194 --> 00:42:11,768
And I say that because nobody wants
nuclear weapons, really.
657
00:42:11,793 --> 00:42:15,049
The same as we want a blue planet
free of plastics, you know?
658
00:42:15,074 --> 00:42:18,919
But we are planning on having a
nuclear deterrent
659
00:42:18,944 --> 00:42:21,359
capability for the next 50 years.
660
00:42:21,384 --> 00:42:24,918
You know, we have a new submarine
being built, HMS Dreadnought.
661
00:42:24,943 --> 00:42:27,619
It'll be far more sophisticated
than Vengeance.
662
00:42:30,803 --> 00:42:33,539
Looking back on my few clays on
board,
663
00:42:33,564 --> 00:42:36,259
I've been astonished by what
I've seen.
664
00:42:39,114 --> 00:42:40,848
7,000 yards.
665
00:42:45,284 --> 00:42:46,819
ALARM BEEPS
666
00:42:46,844 --> 00:42:48,289
Five, four, three...
667
00:42:48,314 --> 00:42:50,728
Weapons has my permission
to fire.
668
00:42:50,753 --> 00:42:53,339
...two, one. Bombs away.
669
00:42:53,364 --> 00:42:57,209
It's been a bewildering and moving
experience,
670
00:42:57,234 --> 00:43:01,728
but it's focused my mind on what
HMS Vengeance really is.
671
00:43:06,753 --> 00:43:10,539
For me, HMS Vengeance is a real
paradox.
672
00:43:10,564 --> 00:43:13,978
As an engineering masterpiece,
it is one of the most
673
00:43:14,003 --> 00:43:18,918
complex technical creations mankind
has ever accomplished,
674
00:43:18,943 --> 00:43:21,419
and it's certainly thrilling.
675
00:43:21,444 --> 00:43:25,739
But at the same time, it is
the deadliest of weapons.
676
00:43:25,764 --> 00:43:30,098
And if it were ever called into use,
it would likely represent
677
00:43:30,123 --> 00:43:32,539
the end of life as we know it.
678
00:43:34,594 --> 00:43:38,898
Either way, it does exist and I
can't imagine it
679
00:43:38,923 --> 00:43:41,489
being in better hands.
680
00:43:41,514 --> 00:43:44,339
The people I met down on
HMS Vengeance
681
00:43:44,364 --> 00:43:48,179
are amongst the most capable
I've ever met.
682
00:43:48,204 --> 00:43:52,898
And if we are to have this kind of
weapon for the next 50 years,
683
00:43:52,923 --> 00:43:56,179
these are exactly
the kind of people to run it.
684
00:44:23,954 --> 00:44:26,419
