Lockheed Martin and Fujitsu Limited have finalized the first purchase order for a critical component of Japan’s Aegis System Equipped Vessel (ASEV) SPY-7 radar antenna, formalizing Fujitsu as a supplier for the SPY-7 Subarray Suite Power Supply Line Replaceable Unit. The agreement was marked by a signing ceremony and follows a memorandum of understanding signed in May 2025 establishing Fujitsu as a source for the SPY-7 PS LRU, advancing co-production and Japanese industrial collaboration.

 

“Lockheed Martin’s collaboration with Fujitsu cements our commitment to establishing a Japan-based supply chain for ASEV’s SPY-7 radar that will keep the fleet mission-ready for decades,” said Chandra Marshall, Vice President and General Manager at Lockheed Martin. “This is a continuation of our contribution and Fujitsu’s shared commitment to strengthening Japan’s defense capabilities.”

Lockheed Martin’s SPY-7 solid-state radar technology is designed to address evolving threats with advanced detection and tracking capabilities, while enabling simultaneous engagement of multiple targets. The system delivers several times the performance of traditional SPY-1 radars and is used by domestic and international customers, including Japan, and is interoperable with other radars and platforms such as the Aegis Combat System.

 

 

“Fujitsu is honored to commence the mass production of the PS LRU, a critical component of the SPY-7 radar system and contribute to the strengthening of Japan’s defense sector domestic production and maintenance infrastructure,” said Kenichiro Miyazaki, SVP, Head of National Security Business Unit, Fujitsu Limited. “Fujitsu remains committed to solidifying Japan’s long-term defense capabilities and further enhancing Japan’s national security through this partnership with Lockheed Martin.”

Securing a Japan-based supplier for the SPY-7 system underscores the companies’ stated goal of strengthening Japan’s defense capabilities and technological capacity. As the security environment in the Indo-Pacific continues to evolve, the partnership between Lockheed Martin and Japan is positioned as a key element in supporting regional security and prosperity.
