Tokyo and Kawasaki, Japan – Lockheed Martin and Fujitsu Limited, a Japanese multinational leader in information technology solutions, finalized the first purchase order for a critical component of Japan’s Aegis System Equipped Vessel (ASEV)’s SPY-7 radar antenna.
A signing ceremony between the two companies formalized Fujitsu as a supplier for the SPY-7 Subarray Suite Power Supply Line Replaceable Unit (PS LRU), marking a significant step in 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.”
In May 2025, the two companies signed a memorandum of understanding to establish Fujitsu as a source for the SPY-7 PS LRU.Lockheed Martin’s SPY-7 solid-state radar technology allows users to respond to evolving threats with advanced detection and tracking capabilities, while enabling simultaneous engagement of multiple targets.
SPY-7 provides several times the performance of traditional SPY-1 radars and is being utilized by domestic and international customers around the world, including Japan. SPY-7 is also interoperable with other radars and platforms, including 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 SPY‑7 supplier for the ASEV fleet highlights Lockheed Martin and Fujitsu’s joint dedication to elevating Japan’s defense strength and technological edge.
As the security environment in the Indo-Pacific region continues to evolve, the collaboration between Lockheed Martin and Japan will remain a critical factor in enabling regional security and prosperity.
Through a true partnership between Lockheed Martin and Japan’s defense community, both nations are strengthening Japan’s role in the Indo-Pacific and the broader regional security architecture.
