In the event of an emergency, it was supposed to take charge of the defense of Tokyo Bay, and from February 1944, when the war situation demanded it, the unit was also involved in combat.

The "Naval Aviation Research Committee", which was established in 1912, has laid the foundation for the Imperial Japanese Navy Air Service.

On 1 June 1930 the first class of naval flight reserve trainees joined the service, and after that preparatory training was conducted in Yokosuka until 1945.

The remaining service members returned to Yokosuka by transport plane, but some stayed on Iwo Jima and lost their lives defending the island.

Afterwards the unit was moved to Kyushu and engaged in kamikaze attacks and air defense battles in the Kantō area.
