Re: USS Bonhomme Richard (Wasp-class amphibious assault ship) is on fire

I don't see the Ponce or the Puller as viable for the F-35 as it needs a rolling take off to carry a useful war load. Neither of them offer that possibility. The recently retired Peleliu is the most likely candidate for regeneration, but it would take a LOT of resources to make it work for F-35 acti...

Adding to Ozair's statement, with regard to the B-52, the only reason that an engine swap is even being discussed there is that supporting the TF-33 is getting more and more difficult as the platform ages. Going to a modern engine will certainly bring greater efficiency with respect to fuel and emis...
