Mitsubishi F1M (Pete) History

Imperial Japan's military aviation industry caught up with the world on the road to World War II (1939-1945). This meant buying foreign products over a period of time while observing changes in the major military powers of the time, some of which were visited directly by Japanese representatives.

All of this happened in an attempt to build a viable local aviation industry that would bring the Japanese Air Force into the modern era. This commitment ultimately proved fruitful, as the early war planes on display by the Empire were some of the best of their kind in the world, and served the vast Japanese war machine during Japanese campaigns to conquer large swathes of the Pacific and Asia.

Mitsubishi is best known for its classic A6M Zero fighters at the end of the war, but the company also produced several notable bombers and experimental aircraft. One of his seemingly little-known (or largely forgotten) contributions became the popular F1M seaplane, used primarily for water reconnaissance and firing at warships. Work on the aircraft began in 1934, and the biplane's first flight was recorded in June 1936, followed by service in 1941.

About 1,118 aircraft were used by the Imperial Japanese Navy (IJN) in the ensuing world war.

Made four prototypes of the F1M1 model that proved the design wasn't flawless. Directional stability was left to be improved, and water handling characteristics were not entirely acceptable, requiring extensive testing and modifications, during which many aspects of the aircraft were modifiedoften for the better.

The extra commitment resulted in a much improved F1M2 brand, which developed into an excellent aircraft under the pressure of the war. A two-seater version of the brand followed in the form of the F1M2-K.

Mitsubishi managed IJN's early production program, producing a total of 524 aircraft before the load fell to the 21st Naval Air Arsenal (Sasebo), with the remaining 590 aircraft subsequently completing a total of 1,118 aircraft (including four prototypes) .The aircraft served on a variety of Japanese warships and became a recognized performer, playing roles large and small in a variety of major events (including submarine hunters and search and rescue) - from supporting amphibious assault operations to participating in naval battles such as The famous Battle of Midway in June 1942. They played a role in the vast Pacific campaign until the war ended in August 1945 - such is their battlefield value.

At the end of the war, with the Japanese initiative almost lost to the advancing Allied wave, the remaining F1M seaplanes were deployed as a localized defense over the Japanese mainland, where it used its value against stronger, higher quality aircraft used by the enemy.

The F1M was recognized by the Allies under the codename "Pete". The aircraft is also partly used by the armed forces of Indonesia and Thailand.
