Sukhoi Su-9 (1946)

From Wikipedia, the free encyclopedia

This article describes the first aircraft to carry the Su-9 designation. For the later supersonic interceptor, see Sukhoi Su-9.

The Sukhoi Su-9, or model K was an early jet fighter aircraft built in the Soviet Union shortly after World War II. While it bore a superficial resemblance to the Messerschmitt Me 262, it was not related to that aircraft. The first flight took place on November 13 1946 and trials the following month proved promising. Rather than put it into production, however, Sukhoi abandoned it to develop a refined version instead, designated the Su-11 (1947). Not to be confused with the later 1960s Su-11.

Note: Some aviation texts suggest that Josef Stalin rejected the Su-9 due to derogatory comments by Aleksandr Yakovlev, calling the Su-9 "just another copy of the Me 262."
