    You think a subsonic weapon would penetrate 6 inches of armour. Honestly?. Do you know how thin hull plating is for a modern warship?. If it would penetrate 6″ of ordinary hull plate, let alone hardened armour, it would have been right through the Stark and the Sheff before the warhead detonated!.

    5-10mm for the hull plating i’d assume. From memory Aluminium hulled boats for inland are 2-3mm from memory.

    Precisely how much trouble do you think?. IF it took 6 repeated impacts on precisely the same plate and penetrated what damage do you think an Exocet would do to a ship with that kind of mass?.

    About the same that happened to the County class Destroyer, a few burnt out compartments. As in, the same damage as if hit by a couple of shells.

    Think about that. ‘Sunk her’ is the hint.

    Yup, I think a famous person once said ships are sunk by letting in water, not by letting in air.

    You think that their WW2 vintage Oerlikons would be less effective than the WW2 Oerlikons we were using on their Skyhawks do you?.

    Depends how many and how they were guided, there were only three ships.

    Destroyed it if they got into guns range. Exocet could not have dealt with the threat on its own – we’d seen how vulnerable it was to softkill seduction already ourselves. Plus we were facing an Exocet threat against us from their DD’s although mitigated by the same softkill factor. Taking Exocet out of the equation you are looking at 4.5″ Mk6’s and Mk8’s (and the Mk8 was no great shakes in ’82 believe me!) taking on a cruiser while the carriers try to run. Its not a pretty scenario.

    When were Belgrano’s engines last refitted? How fast was she? Scatter the fleet train and maintain the carriers and escorts a safe distance away while you await the arrival of [insert SSN name].

    How precisely could sea skua be targeted? could it be guided to a specific part of a target vessel?

    Sirius? I thought her Deck was pretty much unusable due to wind flow issues or something similar?

    just a forward screen of T42s

    There would have been more Radar pickets as well, plus the RN CAP, plus additional Harriers on standby on the Carriers.

    Remember that you are talking about 7 A4’s with dumb bombs, charging straight into the middle of an RN task force with Sea Cat, 40mm guns, 4.5″ guns, plus the Sea Dart on the T42’s as well as on Invincible herself.

    Half a chance that the RN Harriers would outnumber the A4’s by the time they got to Invincible as well.

    $$$$$$$

    Or they don’t want to risk a problem with one particular engine taking out their entire fleet.

    I’d say an Argentine attack would be fought off by Harriers and the Escorts. Assuming the Argentines actually found the actual main task group.

    The British has more Harriers then the Argentine Carrier can embark.

    Half a chance the Argentine carrier would get sunk by a British Submarine if it stayed at sea.

    I got a bit bored and thought I’d have a crack at this design stuff.

    What I did here was add a flight deck to the standard Caiman200 design which I do seem to favour for this project. The aft is slightly enclosed aka Tobruk fashion but the landing grappels are still exposed, I moved the comms antenas around a bit to allow flight ops and I added an MRH-90 (borrowed it from Stan Hyd’s Mornington Class OPV design) to give the desired effect.

    The added internal area would create extra room for the surgery mentioned on one side of the vessel and on the other side the increased fresh water equipment and possibly some extra storage room- maybe even enough room for a holding room for immigrants or unlawful people.

    The question is though, how stable would it be after that change?

    Would it turn turtle in a 1metre swell let alone a 10 metre swell? πŸ˜€

    The last voyage of ” Old Lady”, when Jeanne d’Arc met Charles de Gaulle.

    And an elegant old lady she is.

    If we were to go with the US (again), by leasing the LA Class, what submarines does the US have to offer that we might ultimately buy?

    The Virginia Class, but I prefer the Astute as they seem to have a more flexible weapons loadout, Virginia is less flexible IMO, because of her VLS.

    The R22 and R44 are marginal as it is here in Australia in hot climates….
    I doubt they would be any use in the desserts of Iraq etc..

    Arent those the ones with the habit of falling out of the Sky out west?

    Could diesels(sp) have provided a viable powerplant?

    Possibly but i’m guessing the weight/volume/power/fuel efficiency trade offs all said GT’s would be better, or they would have used diesels in the first place.

    Oh, its probably easier to replace a GT then it is a diesel….

    If u move the island to the center of the flight deck, would it inhibit air operations? It still takes up the same area, but now its smack in the center of the landing area……but the area is the same.

    How is it in the middle of the landing area? Both islands are on the starboard side of the flight deck. The rear island looks about the same location as a nimitz class lsland and the forward one is on the other size of a hanger lift.

    Wanshan, if you could find deck plans I wouldn’t be surprised if the total area taken up by the two islands on QE is very similar to the area taken up by the one island of Cavour.

    Would be interesting to know anyway. But just becase you have two superstructures doesnt mean the total area used will be higher then if there is one.

    But didnt and never has. That was 60 years ago. US practice is to have as little encumberance as possible of the flight deck. That philosophy has worked pretty well since the 1930s.

    The US isnt using gas turbine generators in there carriers, they never have. Remember that gas turbines require massive air intakes to run through the superstructure to the engine rooms. So as long as it was going to Use Gas Turbines it was going to have a large superstructure.

    What they have done is take advantage of it to increase the survivability of the ship by separating the Gas Turbines around the ship and giving multiple places to control the ship from.

    The area of flight deck taken up would have been the same either way

    eg. Look at the size of the stacks on the image of the invincible class below

    Would that matter much, if the smoothed-out superstructure remains vertical rather than angled (just making a larger reflecting surface, though with less scatter)?

    I don’t know how they are doing it, but if they are going to the effort of putting these in , I assume they would be sloped….

    I read somewhere that they were getting screens fitted to the sides of the superstructure to smooth out the structure and make them more stealthy. From what was said, the models havent had all the latest changes added to them yet.
