Japan MOD to Explore Acquisition of Common Engagement Capability

By Ben Rimland
The Mainichi Shimbun reports that Japan’s Ministry of Defense (MOD) is in the midst of studying the feasibility of equipping its next-generation Aegis destroyers and E-2D Advanced Hawkeye AWACS with Cooperative Engagement Capability (CEC).

CEC is a “sensor netting” system that links together detection and tracking sensors of aircraft and ships to provide an “integrated fire control capability” for warships. The system is specifically designed to facilitate allied air defense efforts by transforming AWACS platforms into extensions of an allied surface ship’s own sensor suite.

MOD is currently set to procure four E-2D Advanced Hawkeyes and two new Aegis destroyers in 2019-2020. The Mainichi reports that acquisition of CEC for the two new Aegis vessels is scheduled, while installation of CEC capability for the E-2D is under study. The report further notes that consideration of CEC comes at approximately the two year anniversary of the promulgation of limited collective self defense for the Japanese Self-Defense Forces, capability that came into force a year after the 2015 passage of the national security-related laws.

A CEC capability would allow Japan’s Aegis-equipped destroyers to remain in the rear area of a potential engagement, allowing their missiles to be guided by faster-moving assets closer to the fight. At present, Japan’s Aegis vessels are capable of utilizing only their own radars for guidance and detection of enemy missiles and aircraft. CEC would both expand the detection range of Japan’s Aegis vessels and strengthen interoperability with American assets.
