The plane in these pictures is still officially the 'Air Vehicle Number 1', a prototype, on board the USS George
Washington CVN-73 for catapult fit checks. Not exactly still Top Secret but certainly not yet made public..
It will be known as the F/A-37. Although specs are classified, it is believed to be Mach 3.5 (top speed in the
Mach 4 range), super-cruise stealth fighter/bomber/interceptor with approximately a 4,000nm range. Awesome!
