In the mid-1930s, the concept of the ‘cruiser fighter was very popular in design and planning circles. The Grokhovsky G-38 was one of many examples of this class of fighter that never left the drawing board. It was a twin-boom, multi-seat heavy fighter comparable in concept to the Dutch Fokker G.1 or American Lockheed XP-58 . The G-38, however, was remarkable in a number of respects, most significant of which was the execution of the twin-book concept. The Fokker and the Lockheed were large, bulky, even clumsy aircraft, as was the original take on the G-38. When Grokhovsky hired the young Pavel Ivensen to work on the project, however, the aircraft was transformed into something rather exciting. The new G-38 was tiny for a three-seat aircraft, with a wingspan of 13.4 m (compared with 16 m for the P-38 and 17 m for the Fokker G.1) and ultra-neat packaging. The crew were contained in a torpedo-shaped pod faired into the broad wing centre-section, and the two Gnome-Rhone radial engines tapered to super-slender booms. It had an incredibly low frontal area for an aircraft of its class, and a high wing loading for the time, and it’s safe to say that it would have been fast. Most remarkable of all was the fact that the preliminary designs were approved in 1934, making the highly modern looking G-38 contemporary with the Hawker Hurricane and Curtiss P-36. Had it not been cancelled (for ‘unknown reasons’, around the time of the major Stalinist purges), it is intriguing to consider what the aircraft might have done for the otherwise lacklustre heavy fighter class.
