Bell P-76
The Bell P-76 was the proposed designation for a production model derivative of the XP-39E, a single-engine American fighter aircraft prototype of World War II. == Design and development == On 26 February 1941 the United States Army Air Corps (USAAC) placed a contract with Bell for two prototypes (41-19501 and 41-19502) that were intended to be a major improvement on preceding P-39s. In particular, the XP-39E was intended to address the poor high-altitude performance of the Airacobra.
