La-176 by S.A.Lavochkin

The La-176 was a swept-wing fighter similar to the La-168, but with increased wing sweep (45°). The La-176 was one of intermediate stages on the way to supersonic fighter. Trials started with with the RD-45F engine, later replaced by the VK-1 engine. It was fully armed and equipped fighter, not just a 'clean' record setting craft.

It became the first Soviet (World??) fighter to demonstrate sustained horizontal supersonic flight (after shallow dive acceleration). This happened December 26, 1948 with pilot I.E.Fedorov on controls. Later speed M=1.02 was demonstrated by O.V.Sokolovskij in shallow dive.
Trials were interrupted by fatal accident, when canopy was opened on takeoff and O.V.Sokolovskij was killed.
Gained experience helped in development heavier La-190 and La-200 supersonic jets.
One built.
