Japan Air Self-Defense Force
Encyclopedia
The , or JASDF, is the aviation
branch of the Japan Self-Defense Forces
responsible for the defense of Japanese airspace
and other aerospace operations. The JASDF carries out combat air patrols around Japan
, while also maintaining an extensive network of ground and air early warning radar
systems. The branch also has an aerobatic team known as Blue Impulse
and has recently been involved in providing air transport in several UN
peacekeeping missions.
The JASDF has an estimated 45,000 personnel in 2005. As of 2010, the JASDF operates 805 aircraft, 374 of them being fighter aircraft.
, Japan did not have a separate air force
. Aviation operations were carried out by the Imperial Japanese Army Air Service
and the Imperial Japanese Navy Air Service
. Following World War II the Imperial Japanese Army
and Navy
were dissolved and replaced by the JSDF with the passing of the 1954 Self-Defense Forces Law with the JASDF as the aviation branch.
The Air Defense Command has northern, central, and western regional headquarters located at Misawa
, Iruma, and Kasuga, respectively and the Southwestern Composite Air Division based at Naha on Okinawa. All four regional headquarters control surface-to-air missile units of both the JASDF and the JGSDF located in their respective areas.

airborne early warning aircraft.
The nation relies on fighter-interceptor aircraft
and surface-to-air missile
s to intercept hostile aircraft. Both of these systems were improved from the beginning of the late 1980s. Outmoded aircraft were replaced in the early 1990s with more sophisticated models, and Nike-J missiles have been replaced with the modern Patriot PAC-2 system.
The JASDF also provides air support for ground and sea operations of the JGSDF
and the JMSDF
and air defense for bases of all the forces. Although support fighter squadrons started being modernized in 1989, they lacked precision-guided weapons for support of ground operations and attacks on hostile ships, and JASDF pilots receive little flight training over oceans to prepare for maritime operations. Base defenses were upgraded in the late 1980s with new surface-to-air missiles, modern antiaircraft artillery and new fixed and mobile aircraft shelters.
The JASDF is not allowed to have strategic bombers for that would go against the self defense–only policy.
