with the end of the 1940s and official end of the Second World War, it was very clear to the higher ups of the Imperial Japanese Navy that a large rationalization was in order after such a prolonged period of conflict, during this rationalization, it was found that certain aspects of the imperial navy, were woefully underdeveloped with the biggest one of these being anti-submarine Warfare, despite the Americans not having the largest submarine Fleet in the world, it was found that many losses could have been prevented if suitable anti-submarine aircraft and warships would have been available, as a result starting in 1951, began work into designing a new dedicated carrier based ASW aircraft, after finalising the requirements the contract was put out to many of the Japanese aircraft manufacturers, with the entry from Yokosuka Naval Air Technical Arsenal, proving itself to be the superior aircraft during trials.
The Q4Y would very quickly find an opportunity to prove itself, when in 1958 a year after its introduction, a Chinese maritime Defence Force diesel-electric submarine would go rogue after reports of Japanese brutality in several cities and villages, as a result the full anti-submarine might of the Imperial Japanese Navy was called into track down the rogue submarine, after a two-week long Chase the submarine would be sited 64 miles off the coast of mainland China buy a pair of World War II vintage h-6k flying boats operated by the Chinese advents Force, the location of the submarine would be transmitted to the 1st carrier division which was operating in the area at the time, a squadron of 6 Q4Y's would be dispatched from the carrier kaga, after a further 2 hours of searching the submarine would be located on the surface, however as the aircraft closed in for their attack run, the submarine initiated a crash dive, the aircraft of the group Q4Y (へ-516), would manage to score a hit on the diving submarine, with the submarine submerged aircraft return to the carrier, after the submarine not having been cited for several days and a large patch of while being spotted at the approximate location of, it was concluded that the hit on the submarine was indeed a fatal one with the submarine sinking to the bottom, as a result vindicating that still new Q4Y in the eyes of the Navy.
with the success of the Q4Y, it was decided by the Imperial government to to sell a slightly modified export version of the aircraft too many of its Partners in the co-prosperity sphere, with the largest order of 68 going to the Pacific States of America, which despite not having an aircraft carrier of its own, the aircraft still prove themselves reliable and effective at the mission they were designed for, another large-scale operator of the aircraft was the Philippine maritime Defence Force, with the Q4Y 3's operating of the navy's only carrier BRP Gregorio del Pilar starting in 1960, throughout the rest of the 1960s the aircraft would be operated by a number of countries in the co-prosperity sphere, surprisingly a few aircraft even be sold to Benirteixo Republic, one of the few countries in the world not directly under control of either the Germans or Japanese, however by the beginning of the 1970s the Q4Y was beginning to look it's age, as a result starting in 1973 the Imperial Japanese Navy began looking into replacing the old but reliable bird, with this enquiry eventually leading to the Q8K aircraft in 1976.
by the mid 1980s the Q4Y had been completely replaced by its successor, however many of the aircraft that were taken out of service, were stored in a aircraft rehabilitation centre in northern Australia just in case they were needed again in the future, this decision would pay off in 1984 when the Japanese army and Air Force agreed to help Indian communist rebel cells in destabilising the control of the greater germanic reich in northern India, to do this many aircraft most of which were old and outdated were employed with markings that were hastily painted over, Q4Y was chief among them, with a total of 36 ex Navy aircraft being retrofitted for ground attack, despite not being designed as a ground attack aircraft Q4Y proved itself to be a reliable aircraft in this role, having a confirmed total of 128 armored targets destroyed between the 38 aircraft, with only 4 aircraft being lost in the 6-month operation, however with a full-scale southern Indian counterattack on the Japanese side of the border in late August 1984, many of the aircraft would either be abandoned at the airfield they were stationed at by the retreating Japanese forces or would be flown to other Japanese held air bases in Southern China, however by 1985 the Japanese army and Air Force had managed mustards forces and repel the southern Indian advance, and with their duty fulfilled the remaining Q4Y's would be retired for the final time, bringing an end to the almost 30 year service of the remarkable aircraft.
