The Yak-141, being the world's first supersonic STOVL (short take-off/vertical landing) aircraft, has three engines: one lift-cruise R-79 with a thrust of 15500kg and two small-sized RD-41 of 4100kg each. The powerplant allows the plane to lift off vertically with a weight of up to 15800kg. Alternatively, the Yak-141 can perform short take-offs (60-120m) with a weight of up to 19500kg. In the latter case the combat radius increases by 1.5-2 times and patrol time in the combat zone by two times. The pilot can use afterburner even when the nozzles are deflected. The Yak-141's integral flight-control system sets power and deflection of the nozzles so as to optimise making vertical/short take-offs and landings.
The Yak-141M was meant primarily for ground-basing. Introduction of new flight regimes, as well as new take-off/landing techniques, has entailed changes in the airframe, leading to a new design, the Yak-141M. The Yak-141 had its maiden flight some 25 years ahead of the timeframe set by foreign manufacturers for creation of such a plane. After the show in Farnborough, Yakovlev design bureau worked together with Lockheed on Joint Strike Fighter (JSF) programme. As a result, Lockheed's final JSF proposal resembles... the Yak-141M.

" the temperature would be very high to the point to damage
the flight deck. "
Don't hover!!
Work.

The Yak-41 (o-141) during its tests in the "Admiral Gorshkov", used in
hovering the afterburners to plenary session? This was possible dice
the enormous push, 14.000Kg, unbalanced the pitch attitude? I
believe that the temperature would be very high to the point to damage
the flight deck.
