The Lockheed P-400: A Forgotten Hero of World War II


The annals of World War II aviation history are replete with iconic aircraft, many of which have achieved legendary status. However, among the stars of that era, there are hidden gems often overshadowed by the more famous names. One such aircraft is the Lockheed P-400, an unsung hero of World War II.

In this blog post, we’ll delve into the history and significance of the Lockheed P-400, a plane that deserves recognition for its role in the conflict.

The Lockheed P-400: A Brief Overview

The Lockheed P-400, also known as the Model 322, was an American fighter aircraft developed during the early 1940s. While it didn’t achieve the same fame as its contemporaries like the P-51 Mustang or the P-47 Thunderbolt, it played a notable role in the war effort, particularly in the Pacific theater.

Key Features and History

Derived from the P-38 Lightning: The P-400 was based on the P-38 Lightning, one of the most recognizable aircraft of World War II. However, it featured a single engine, unlike the P-38’s twin-engine configuration.

Light Armament: The P-400 was equipped with a 20mm cannon and two .50-caliber machine guns, which were considered lighter armament compared to some other fighters of the time.

Operational Service: The P-400 served with various Allied air forces, including the United States Army Air Forces (USAAF) and the Soviet Air Force. It was actively deployed in regions like the Aleutian Islands, New Guinea, and the Philippines.

Soviet Service: The Soviet Union received a significant number of P-400 aircraft as part of the Lend-Lease program. They were used on the Eastern Front and in the defense of Moscow. The P-400 was designated as the Bell P-63 Kingcobra in Soviet service.

Significance of the Lockheed P-400

Versatile and Durable: The P-400, with its single-engine design, was versatile and relatively easy to maintain. It proved capable of withstanding the harsh conditions of the Pacific theater, where it often operated from remote airfields.

Critical Defense: In the early years of World War II, the P-400 played a vital role in defending against Japanese forces in the Pacific. It was often tasked with intercepting enemy bombers and providing cover for ground operations.

Soviet Contribution: The Soviet use of the P-400 (designated as the P-63 Kingcobra) on the Eastern Front played a significant role in the defense of Moscow and in the fight against the Luftwaffe.

Legacy: While the P-400 might not have become as famous as some other aircraft, its legacy endures in the form of the P-63 Kingcobra, a development of the original design that continued to serve in various air forces post-war.


The Lockheed P-400 might not be as celebrated as other aircraft of its era, but it should not be forgotten. This unsung hero played a pivotal role in the defense of Allied territories in the Pacific and contributed to the war effort on multiple fronts, including the Eastern Front in Europe.

Its versatility, durability, and service record exemplify the spirit and dedication of the men and women who served during World War II. The Lockheed P-400 deserves recognition as a testament to the ingenuity and resilience of the era’s aviation industry and the bravery of those who piloted it into combat.
