Now we are the 6th generation threshold where CAD computers can tough it out with a new breed superseding the F-22. MY proposal is simple:
Build 300 F-51 Mustang II's for the USAF(200) and (Navy's 100) a few (?) with a lift mechanism for the UNSMC austere capability for its amphibious force offloading ships from the USS 6 America class Landing Ship Dock without an amphibious deck included. It would have the capability of the world's toughest fighter not unlike the F-22's own chops. Invisible to radar imaging and exceptional situational awareness and having extreme offensive capabilities when like to all other weapon systems in the battlespace. If a prototype was built now it would be just in time by 2030. Of course new engines!
