S.H.I.E.L.D. Helicarrier

Design
The S.H.I.E.L.D. Helicarrier serves as Nick Furys flagship of his fleet and sometimes headquarters of the Avengers. It can dive underwater, fly with its huge four turbined fins, and uses a cloaking device to turn invisible. It has a hangar at back to send s.h.i.e.l.d. fighter jet planes into battle or arming them with nuclear missiles to destroy an army or enemy base, and a landing plane for aircraft to land on.
