Of all the aircraft shown by Russia at this year's Farnborough air show, the most technically advanced was Yakovlev's venture into supersonic V/STOL, the Yak-141 'Freestyle'. The Bureau made no secret of the fact that this surviving prototype was displayed to engender some interest in the project and that unless support was forthcoming from a prospective user, development will he halted and the design cancelled. The aircraft is shown hovering with flaps and slats extended.
Underwing pylons were fitted to the display aircraft and pictures have shown them carrying missiles although weapons trials have not proceeded very far.
The heavily-forged main gear legs which were designed with carrier landings in mind. The tyre shows the usual wear seen on many Russian aircraft.

A view of the aerodynamic and recirculation strakes just forward of the main undercarriage leg. Also visible is the semi-buried 30mm cannon offset to port.
Only one public display was performed by the Yak-141 at this year's Farnborough and during its hover and transition stages it remained much higher that the altitude more usually associated with the only other pure V/STOL aircraft, the Harrier.
The main undercarriage doors form part of the lower strake which has additional transverse surfaces extending when the main engine nozzle deflects to act as extra recirculation dams.
