    Not quite sure how we've ended up on the topic of "frickin' lasers...", but that's a bit of a silly and naive comment, gadget. At deck-level, you're talking about a horizon in excess of 11nm. For a 'munition' travelling at the speed of light, that's more than enough reaction time against an incoming threat, particularly as that threat will itself be above sea level. The possibility for laser weapons is very interesting, but is still firmly in realm of fantasy fleets for now.

    Maybe a little excessive, distance to horizon is 3.57 times the square root of the height above sea level, so unless the deck is 31m above sea level, 11nm is a stretch. At sea level the horizon is only 3-4 miles away.

    I'll be honest, I had forgotten the formula and the exact waterline-to-deck height of QE, so took a stab. I suspect it's not far off. That said, it doesn't particularly matter in the context of light-speed defensive weapons.

    At mach 2.5 or so and 3-4 miles distance before you start shooting it's going to be burn-through time that's going to get you.

    Interesting article about the simulators the crew are being trained on to operate the carriers.

    Yeap as the V stands for Vertical as used in the AV-8B.

    Anyway the interesting factor which may need to be taken into account for Crowsnest is what the USN do about this :-

    If the USN decides to go for the V-22 solution over the Greyhound then i suspect the UK would give it serious consideration as a possible Utility/AEW platform, should the USN go with the revamped Greyhound then they will stick with the Merlin as a platform.

    I can confirm its NOT John Prescott OR LUSTY LOL
    You sure its not Lusty? I see from AIS that she is just off Dundee in the North Sea along with HMS Bulwark and a Dutch naval vessel. Or were you referring to Bulwark?
