Royal Navy Deployed Laser Weapons During the Falklands War

Posted by Unknown on from the zap-zap-you're-dead dept.

Zothecula writes "Despite recent demonstrations by the US Navy, we still think of laser weapons as being things of the future. However, previously-classified British documents prove that not only were the major powers working on laser weapons in the 1970s and 80s, but that they were already being deployed with combat units in war zones. A letter from the Ministry of Defence released under the 30-year rule reveals that laser weapons were deployed on Royal Navy ships during the Falklands War in 1982, and that the British government was concerned about similar weapons being developed behind the Iron Curtain."

    They were only strong enough to "dazzle" pilots, not do any actual damage.

      the only Argentinian I've discussed this with (I'm British BTW) said he'd never heard of the Falklands or the Malvinas until the miltary government decided to start a war over them. Ditto me in the UK. The populace in neither country knew or cared.

      Supposedly the RAF tactics were to let the Argentine fighter bombers complete their attack runs while the ships were defended with chaff and decoys.

      And who, exactly, claims that?

      I'm not aware of any Harrier pilot who's ever said they deliberately let the Argentinians attack ships before they engaged. Nor was speed a big issue when they were primarily using Sidewinder missiles, and the Argentinians didn't have enough fuel to fly supersonic for long and still attack.

      "no actual damage"? They could permanently blind pilots.

      Look on the bright side. When they were blinded while flying fifty feet off the ground, they would only have about two seconds to worry about whether their eyesight would ever return.

      That's funny. I'm American, and I'd heard of the Falklands prior to the war. We had been told, in a physics class, about the first battle of the Falklands and how the British had to correct for Southern Hemisphere coriolis effects manually by scratching new lines into their sights (which only had northern hemisphere corrections).

      The other funny thing is - that story may not even be true! There are no good historical references to this; plus it's not like the British in WWI were exactly strangers to the seas below the equator... But in any case I already knew where the Falklands were located as the rhetoric heated up.

      You have to remember this was back when the pickets ships were the primary means of defence of the fleet still, you don't want your own ships accidentally shooting down their own air cover, so they positioned the picket well forward. Not necessarily the best plan, but you can see the problem - ultimately the goal is to defend the carriers, not the picket ships. The picket ships actually took out a number of enemy aircraft with missiles because that's their job.

      No one likes to say 'sorry, but your job is to get killed before someone on a bigger more important ship' but that's very much the job of destroyers and frigates. You force the enemy to destroy the escorts first, or take the risk of flying over them and getting shot down.

      The royal navy suffered very much from several problems, one of having some engineering problems with their ships (turns out aluminium can catch fire), two that they couldn't lock on to ships coming in low, and three couldn't deal with exocet missiles.

      The royal navy faced the unenviable challenge of not having enough aircraft (only about 50 total). The Argentine situation meant they could (early on at least) put 30 or 40 aircraft anywhere in a large area of operations. That's a serious problem. You can't have too wide an air cover, you'd have too many aircraft spread out and not be able to defend, and you can't risk a carrier. That problem is overcome by defeating the enemy in detail in small pieces until he doesn't have the force to concentrate. Which is what the royal navy did essentially, they traded destroyers and frigates for aircraft kills until the Argentinians didn't have enough aircraft or exocets, at which point the british had air superiority for a ground invasion.

      The Argentine subs 'wreaking havoc'?!!? Argentina had TWO subs total. The 1st sub, the ARA Sante Fe was used to land some commandoes then later was caught on the surface by a helo and was too stupid to dive and so damaged by the helo's rockets and depth charges that it had to be beached on the coast with the crew later being captured. The 2nd sub, ARA San Luis, did patrol and did make three attacks on British ships but never hit ANY targets and were counter-attacked for over 20hours. The sub was in bad shape as its fire-control systems were completely down requiring all attacks to be calculated and launched manually. There were problems with torpedoes, equipment, etc. Argentinian submarines didn't do much and didn't effect the outcome of the war at all. Now the British had three subs in the area with 2, the HMS Spartan and HMS Splendid being mainly used as successful scouts of the location and movement of Argentinian naval vessels. And the 3rd sub, the HMS Conqueror, not only engaged but also sunk the Argentine Cruiser ARA General Belgrano with heavy loss of life. It did this using WWII vintage straight-running torpedoes instead of modern torps. It easily left the scene while the Belgrano sank. After the loss of the Belgrano, all Argentinian Naval ships stayed within 12 miles of the Argentine coast for the rest of the war. The Argentinians on the Belgrano and escorts had no idea the Conqueror was even there until her torpedoes stuck. Where as the British surface ships could detect and defeat the Argentine subs and were not detered by them at all. Argentinian subs - did nothing to really help their side and in fact lost half of their sub fleet while doing no damage to any British vessels but British subs had no losses, sank an enemy cruiser after which the entire Argentine Navy stayed within 12 miles of their own shores never venturing out to even hint at engaging the British. British subs sinks one cruiser and the Argentinians give up the entire naval engagement/war. Heck, just the threat of British subs in the area of the Falklands kept Argentine merchant vessels from the area denying any sea-lift / support from Argentine ground forces.

      I will bet they didn't, due to lack of air to air radar - the RAF operated the GR-type Harrier, suitable for ground attack and recon only, while the air defence force was made up of Royal Navy FRS Harriers, which were equipped with radar as part of their fleet defence ability.

      As a member of the UK public at the time, most of us didn't care what direction the Belgrano was heading, if it was the vessel of an enemy which had occupied UK territory then we wanted it sinking. It was being ambiguous which had got the UK into trouble in the first place, so something as unambiguous as a torpedo was sending the right message as far as we were concerned.

      i think that's unlikely, personally.

      I believe the Argentine navy would, had it not been savaged earlier, parked its carrier within operating range of the Falklands as soon as the landings started. Some loss of life was inevitable from the moment the Argentinians decided to invade the Falklands and not agree to leave. Also the Argentine submarine San Luis fired a torpedo at British ships the day before the sinking, so both sides were on the same page as far as hostilities were concerned.

      The Sun headline is agreeably controversial. Whilst regretting the loss of life, I think it expressed some relief that we were on the right side of the scoreboard.
