The Nakajima B6N Tenzan ( Japanese: 中島 B6N 天山 - "Heavenly Mountain", Allied reporting name : Jill) was the Imperial Japanese Navy's standard torpedo bomber for the final years of World War II. It was a development of the Nakajima B5N and replaced that aircraft in service. Although a highly-effective torpedo bomber, by the time it reached service, the US Navy had already achieved air superiority over the Pacific, and the type never really had the opportunity to display its full potential.
The B5N's weaknesses had shown themselves early in the Sino-Japanese War and as well as updating that aircraft, the Navy began seeking a replacement. In 1939, it issued a specification to Nakajima for an aircraft that could carry the same weapons load as the B5N but do it faster and over a longer range. The design was restricted by the fact that it also had to fit into the flight-deck elevators of existing aircraft carriers - which the B5N already almost filled. This latter restriction resulted in the characteristic shape of the B6N's tail fin with its forward-sloping rudder.
Unlike its predecessor, development was long and fraught with problems, including serious instability shown by the prototypes after flight testing began in early 1941, engine problems, and problems associated with carrier take-offs and landings. Rectifying these issues would mean that two years would pass before the aircraft was finally ready for squadron service. Even then, the aircraft's weight meant that it could only operate from the largest carriers in the fleet.
The B6N1's combat debut was nothing short of disastrous. The Battle of the Philippine Sea had them operating in an environment where the US had such air superiority that they failed to inflict any significant damage whatsoever, whilst taking massive losses from the US Navy's new F6F Hellcat fighter. Following this debacle, the Navy ordered several changes to the design, most notably a new engine, resulting in the B6N2.
By this point, small improvements in the B6N's performance were amongst the least of the Japanese Navy's problems. When the new model became available in mid 1944, it had already lost most of its large carriers, and was becoming desperately short of experienced pilots. The vast majority of B6N2 operations therefore took place from land bases, and failed to achieve any major successes. They were extensively used in the Battle of OkinawaThe Battle of Okinawa fought on the island of Okinawa in the Ryukyu Islands (south of the four big islands of Japan) was the largest amphibious assault during the Pacific campaign of World War II. It was the largest sea-land-air battle in history, running, where they were also used for kamikazeKamikaze ( from kami meaning "god" and kaze meaning "wind") is a Japanese word — usually translated as divine wind — which came into being as the name of a typhoon that saved Japan from a 1281 Mongol invasion fleet led by Kublai Khan. However, when used i missions for the first time.
With the Navy's priorities now shifting to the impending defence of the home islands, a final version of the aircraft was produced for land-only use, sacrificing its carrier operations features in exchange for a little more performance due to weight savings. Two B6N3 prototypes were completed, but Japan surrendered before this variant could be put into production.
A total of 1,268 B6Ns were completed, almost all of them B6N2s.
