Completion of the development of fixed-wing patrol aircraft P-1 and assignment to MSDF Atsugi Air Base

The MOD possesses fixed-wing patrol aircrafts, which are used mainly for constant wide-area monitoring and patrolling in the sea surrounding Japan. They carry out diverse missions, including disaster deployment and search of vessels in distress. The aircraft are assigned to five bases throughout Japan, such as MSDF Atsugi Air Base in Kanagawa Prefecture.

Since FY2001, the MOD has been developing the next generation fixed-wing patrol aircraft (P-1) in response to the aging of the existing fixed-wing patrol aircraft P-3C, which have been used since FY1981. On March 12, 2013, the development of P-1 was finally completed following the ground tests and test flights.

On March 29, two P-1 aircraft were assigned to MSDF Atsugi Air Base. The location of the base allows for swift deployment to sea areas in all directions from Japan for the execution of various missions, including surveillance operations.

The P-1 has improved detection performance, flight performance, data processing ability, attacking ability and quietness compared to the P-3C. It is expected that the P-1 will more effectively carry out the continuous operations of information collection and surveillance of the sea areas of Japan under peace time and other circumstances.

East Asian Strategic Review 2013

On March 29, the National Institute for Defense Studies (NIDS), a research and educational institution of the Ministry of Defense, released the East Asian Strategic Review (EASR) 2013.

This year’s report marks the 17th publication since 1996. Every year, the EASR analyzes the key security issues of the previous year among the countries of East Asia. This year’s report highlights the leadership transitions in East Asia, as well as the security situation that has been severely aggravated in East Asia. The EASR is widely recognized as an annual security report on East Asia and is cited by international research papers. It is also utilized as a textbook at colleges, universities and graduate schools in Japan and overseas.

The views presented in the EASR are solely those of NIDS researchers and do not necessarily represent the official position of the Ministry of Defense.

Printed copies of the EASR in both Japanese and English are available for purchase. The both editions are also available on the NIDS website.

Return of land areas south of Kadena

On April 5, with attendance of Prime Minister Abe, Japan and the U.S. jointly announced a consolidation plan that the two countries have coordinated for the return of land areas south of Kadena.

For each area the plan details conditions and sequence as well as timelines for return, as part of the realignment of U.S. forces to mitigate their impact on local communities in Okinawa while maintaining deterrence. This was done according to the three categories of returns confirmed in the April 2012 Joint Statement of the Security Consultative Committee (SCC) with regard to the six facilities and areas south of Kadena Air Base, which were to be considered for total or partial return under the May 2006 SCC document entitled, “United States–Japan Roadmap for Realignment Implementation.”

The plan sets forth a specific roadmap for the return of sizable lands (approx. 1,048ha) in densely populated areas.
