It took a long while for a redo of the AS-8 from god knows how long ago. So other than a full redo of the Aircraft, I was able to make actually detailed engines (but note i do not use normal Jet engines).
Specs:
Price=$673,000,000,000.00
Top speed= (Mach 4+ @ 12 km) (Mach 1+ @ 1km(25% throttle))
Range=Yes (don't know, but its Big)
Weapons=
-6 standard missiles (Custom made for the small weapons bays)
-4 Advanced Missiles (near immune to flares)
-1 Repeating Laser (110 shots per second, 5 shots to break stock fuselage parts)

Notes=
-At it's top speed, it becomes impossible to turn on low physics.
-The plane has very low yaw stability(expect fishtailling at lower speeds)

ENJOY
