| Combining a fuselage essentially similar to that of the
Lavochkin La-168 with wings sweptback 45 at
quarter-chord, the La-176 was flown in September 1948
with a 2270kg RD-45F turbojet, and
armament comprising one 37mm N-37 and two 23mm
NS-23 cannon. Re-engined with a Klimov VK-1 turbojet
of 2700kg, the La-176 was claimed to have
exceeded Mach=1.0 in a dive from 9050m to
6000m on 26 December 1948. It was initially
believed that an ASI error had been involved, but the
process was repeated six times during January 1949,
1105km/h being recorded at 7500m, this being equivalent to Mach=1.02. The
La-176 thus became the first Soviet aircraft to achieve
supersonic flight. Further development was abandoned
shortly afterwards when the canopy locks failed
at high speed, resulting in test pilot V Sokolovsky losing
his life.
