Yak-38 Forger [Russia]

Former Soviet Union's (Russia) first operational VSTOL aircraft, this plane shocked the West Bloc by first appearing in the Mediterranean Sea in 1976. The plane had an exceptionally unusual engine layout.
It had 1 turbofan and 2 turbojets. The turbofan engine had vectored-thrusting, while the turbojets performed their functions as lift-jets only. Since the turbofan was working all round the clock, the intake for the engine was a common one (on the sides). But the turbojets were placed just behind the cockpit, and it had a hatch that opened when it hovering mode, with an outlet just below it for the exhaust. The only drawback was that the lift-jet engines served as a burden rather than an asset during foward flight.(See pictures)
