Gr-1 (Grushin-1) by P.D.Grushin

Single-seat two-engine long range escort fighter of conventional twin-tail layout. Gr-1 was an all-metal aircraft with armored cockpit. It was very compact for two-engine plane (see table), and wing load was very high for the time (182kg/m2).

Gr-1 carried formidable barrel armament (salvo 3.7kg/sec), RS-82 or RS-132 rockets and 500kg of internal bombload.

Design process and construction were done in record short time (nine months). Static trials were performed in Spring 1941. War outbreak forced to stop flight tests and evacuate the aircraft. On the way train carrying Gr-1 was destroyed by the Luftwaffe bombers...

I wonder if the G-38 (Grokhovskij) materials were not transferred to Grushin, when the former team was disbanded...
