Aug 22, 2013 · Both P-39 and P-63 were, at least when compared with other US aircraft, very light. With plenty of power available from late 1942 and late 1943 respectively (up to 1450 and up to 1850 HP, respectively), we are bound to see good climb figures.

Based on the preceding Bell P-39 Airacobra, the P-63's design incorporated suggestions from P-39 pilots and was superior to its predecessor in virtually all respects. The P-63 was not accepted for combat use by the United States Army Air Forces.

Jan 7, 2022 · P-39/P-63 two very different airplanes that looked very similiar. P-39 rounded tail/rudder, much smaller, 3 bladed prop. P-63 much larger, four blade prop, clipped tail/rudder.

The P-39 would be produced in large numbers, though it would be most prominently used by the USSR; the same was true of the P-39's improved successor, the similar "P-63 Kingcobra". This document provides a history and description of the Airacobra and the Kingcobra.

Dec 12, 2024 · The P-39 Airacobra and P-63 Kingcobra were manufactured by the Bell Aircraft Corporation on April 6, 1938, and December 7, 1942, respectively. The P-39 was innovative in multiple ways:

While the P-63 looked similar to the P-39, it was a larger and heavier airplane. Unlike its earlier cousin, which was originally envisioned as a fighter/interceptor, the P-63 was designed as a ground-support/fighter-bomber from the beginning.

Innovative tactics and motivation, coupled with the P-39′s sturdy construction and adequate firepower, proved successful for the Soviets. The P-39 was in Soviet service since 1942; nearly 5,000 were supplied and used on the Soviet-German front, along with 2,400 P-63 Kingcobras, which saw only limited action against Japan at the close of the war.

The Bell P-63 Kingcobra was a considerable improvement over the P-39 Airacobra and although both airplanes looked similar, the P-63 was a larger and heavier aircraft. It was not accepted for combat use by the United States Army Air Force (USAAF), but it was used successfully on the Eastern Front by the Soviet Air Force.
