This is will probably be my best build in a while and I'm not complaining

The Solaris F-57 Black Falcon Mark-3
A multi-role Fighter for the modern age

Ag1 TVC and post stall stuff
Ag2 Canopy
Ag3 Weapons bay
Ag5 SuperSonic Mode

Instructions are also in the game but one tip:
Thrust at 30%, AG1 and keep speed between 350 to 290 for PSM, although the plane will not like what your doing

Back story: After the eventual mediocrity of the A-11, Solaris was on it's last legs and with one last contract they had 2 options; Knock it out of the park or face bankruptcy. After using every contact and using all the resources they had, they eventually developed the Falcon Mark-3, a multi-role Fighter which went on to win wars... The MK-III essentially proved the point that "necessitty is the mother of innovation" so go Capitalism lol. And ironically the Chinese bought a few
