The Quinjet is one of the most powerful transports and assault vehicles ever built. Incorporating the best Stark technology and dozens of systems developed by S.H.I.E.L.D., it gives the Avengers supersonic access to the entire world. It has supersonic top speeds and powerful weapon capabilities.
It is able to fit at least two in the forward cockpit and can fit a squad of fully armed soldiers in the back. It also has a nose-mounted retractable mini-gun.
