I doubt on those stories, in all these years i never read nothing about the acs frigate etc. but the other frigates of spanish navy the f80 i think modernised, are perry something, i am sure they are us design.well, I heard some stories that Gibbs & Cox used to designed an ACS frigate (a frigate with a PESA/AESA based on a Perry hull) for the Taiwanese navy, which eventually Taiwanese didn't build the ship. G&C furter developed that design and later sell the idea to Spanish and becomes the F100.
The newest issue of the Defence today did mentioned the 4th AWD, a 3rd LPD but not a single word about F-35 on LPD. So if the possibility of the 4th AWD, a 3rd LPD is slim, I will say the idea of F-35 on LPD is very likely long dead. Even I myself is a big fan of that idea2
let me say, i do not repeat myself, i want to give my vote, that if the price of f100 is for example, 400 mill euro, and a burke 500 mill euro, australia saves 300 mill euro for the 3 ships, and a harrier cost for example 35 (probably less) mill euro, australia can buy 5 harriers for examples, and refits to us or uk, for the distances in australian region, the speed, range and capabilities of aircraft for small price, for "special operations", we can imagine to integrate the tomahawk or the missil taurus in the harriers (for example 3 mill euro) and for small price we have a briliiant scalpel, really intimidating, at 2000+ km distance shot in a couple of hours with few meter precission etc, ...ok i could go on more comments about the contras stated by some, human effort is "free", and they have saved some cash, but i prefer to leave it as a vote.
Sorry as you see i am not a professional, i like pc games.
cheers!
