US Navy testing an ASROC NDB in 1962 |
One of the things that is talked about
in hush tones about the Falklands Conflict is the deployment of nuclear weapons
by the British with their task force.
This of course is done for good reasons, one they could have been
violation of the Treaty of Tlatelolco, which makes Latin America a nuclear
weapons “Free Zone”, and secondly the public relations backlash if they did
confirmed that nuclear weapons were indeed with the task force. Even today, the Ministry of Defence (MoD)
official statement is that they can either confirm or deny the presence of
nuclear weapons, but that the task force was instructed not to enter the
territorial waters of the Falkland Islands with their nuclear weapons
(violating the Treaty of Tlatelolco).
But in an official document from the MoD states the nuclear weapons that
were part of the task force did not arrive back the UK until two to six weeks after
the hostiles had ended on the RFA Fort Austin and RFA Resource, respectfully. A PDF of the eight page MoD’s document can be
found here (link - click on the link "View the item you were looking for"). In this entry, I am going to write up a bit
about these nuclear weapons, what happen with them during the conflict, and how
will this will play into my upcoming Falklands naval games (and bit more on
that too). I am hoping that anyone
playing a combined arms Falklands campaign can use this information to make a
more interesting campaign.
So, what
nuclear weapons did the British have?

WE.177A nuclear depth bomb - inert |
According to
the MoD, they only had the WE.177A
nuclear depth bombs (NDB), or the official nomenclature, “Bomb, Aircraft, HE
600lb, MC (Medium Capacity)” To my
knowledge, the Royal Navy did not have nuclear armed torpedoes for their
submarines.
The WE.177A was designed to be dropped
from either an RAF or a RN aircraft or helicopter, with either a 0.5 kt or a 10
kt warhead depending on the depth or location of the enemy forces. The WE.177A was also designed for either air
burst, ground burst, or submerge burst.

Westland Wasp carring a WE.177A |
As I am only interested in discussing
the immediately availability of the NDB’s by the task force at the time of the
Falklands operation, I am limiting the following list of aircrafts capable of
delivering the NDB within the task force at that time. Those aircraft include for depth charge
attacks only: the Westland Wessex HAS.3, the Westland Wessex HUS, and the
Wessex Wasp. The Sea Harrier FAS.1 was
capable of dropping the WE.177A in laydown (parachute to delay impact),
retarded (time fuze to detonate after impact) to allow the jet more time to
escape. Also, the HMS Bristol was able
to deploy the WE.177A with its Ikara missile system.
What ships had the NDB’s?
HMS Hermes and Invincible in 1982
In the MoD’s document, they show which
ships were carrying live NDB’s, training NDB’s, and surveillance rounds. I am only interested in the live rounds for
now, so the following ships had live NDB’s assigned to them prior to sailing
for the Falklands: Invincible, Hermes,
Broadsword, Brilliant, Fort Austin, Regent, and Resource. It should be noted that the Broadsword removed her training NDB’s prior to sailing, but the
live NDB’s did set sail with her towards the Falklands. It should also be noted that these ships were
carrying a significant percent of all of the NBD’s in the Royal Navy
inventory. I will be touching on how
many in my next section.
Why did the ships not off load their
NDB’s at shore, either the UK or Ascension Islands?
There was a major argument to fully
off load the NDB’s to a safe land location would have delayed the Falklands
operations and put the time schedule in jeopardy (remember, they were in a rush
to beat the sever winter conditions which could have stopped all
operations.) The ships had only 24 hours
at port and it was determined that it would take another 36 hours more to
safely removed all of the NDB’s. This
delay could have also alerted the Argentine forces that the RN was located at
the Ascension Islands and to be better prepared for their arrival.
What happen to the NDB’s in the task
force?
According to the MoD, most of the NDB’s
were transferred at sea (by helicopter or Landing craft) to ships in the task
force with deep magazines (deep in the ship and most heavily protected from
bomb attacks.) Those ships with the deep
magazines were the following: Hermes,
Invincible, Fort Austin, and Resource. The Hermes
was the most heavily protected and it was expected that only had a moderate
chance of damage from a mine or torpedo and minimal chance from an Exocet
missile. The protection on the other
ships had a greater chance of damage from torpedoes. In the MoD’s document, it shows when and
which ships transferred their NDB’s to which specific ship with a deep
magazine. By the end of the transfers
the Hermes was carrying 40% (!) of
the entire RN’s NDB’s inventory (not the task force, the whole RN!), the
Invincible was carrying 25% (!), and
the Fort Austin and Resource was carrying even more, but not
noted. So just between the two task
force carriers, 65% of all the RN’s NBD’s was located.
What would have happen had one the
ships with the NDB’s been hit?
HMS Brillant, only ship damaged with NDB's aboard, but they were the training type
According the MoD, there would not
have been an nuclear explosion (which would be true, look at my previous entry
on my visiting of the atomic bomb site that was dropped on Mars Station,
SC.) However, there could have been
radioactive release; if the ships were still afloat, immediate decontamination
of any radioactive material and the removal of the remaining NDB’s to any of
the remain deep magazine ships; if the ship sank, the NDB’s were either
temporary or permanently lost for NATO operations, and possible recovery by
Argentine salvage operations. This is
not even including public relations nightmares for the British and could
cripple their future of having ships visit other ports.
How will this fit into a Falklands game
or campaign?
I have the rules set, Shipwreck, based
on the recommendations by Rusty Nail over at his blog, "Hurry Up and Wait!" (link) (If you are interested in the Falklands, I highly recommend it!). I also got to play it a couple of times while I was working in Savannah,
GA. I really like the system and plan to
use that for my Falklands naval campaign.
I have 1/6000 ships from Hallmark that I will use, but might consider
bumping up to 1/3000. But the cost,
size, and availability of the ships used in the Falklands conflict got me to
buy the 1/6000. I am going to try to
start painting these up myself (!) over the holidays as they should be fairly
easy to paint. But I digressed from the
topic…
I am looking at a board scope for my
Falklands games and the naval action is a major part of it. First off, I am fairly confident that
Thatcher would have never authorized the use of the NDB’s during the Falklands
conflict, so the RN can’t use them for what they are designed for against the
Argentine forces. So, the first thing is
do I off-load the NDB’s at Ascension? If
I do, that means add two more days to arrive in the area of operations, plus a
greater chance of detection by the Argentine’s 707 recon plane. This will also mean a more aggressive land
operation for when I am doing that to reach Port Stanley before winter
conditions forces the operation to end.
Do I remove the NDB’s to the deep magazine ships? There should be a chance to lose a NDB during
the transfer and that will cause some political loss of Victory Points to
reflect the need to go back and recover the lost NDB. If chose not to transfer, I need to keep
track of which ships have their NDB’s for possible air/submarine attacks. If a ship with NDB’s is hit, is there a
radioactive release (this will be a greater chance in a ship without a deep
magazine)? Do I have to I have to assign
helicopters to transfer the undamaged NDB’s inside of have them for a
anti-submarine screen? Needless to say,
if the Hermes is hit and sinks before
a transfer could take place, there would be a major Political loss for various
reasons. I have not figure up any hard points or rules for any of this, but
this is brain food for people to think about.
