With the proposed US cut backs and our own carriers not coming on line for at least 7 years why not just go the whole hog and either buy or borrow a s/h carrier complete with an airwing to 'tide' us over until the F35 is in full production and our own super doper flat tops have been launched, gone through their workup and had all the niggly bits fixed.
Cull a few more Admirals and their hangers on and we may even be able to afford two.
Tis only a thought...
