Fujitsu secured a contract to manufacture power supply components for Lockheed Martin’s SPY-7 radar systems, the latest move in Japan’s push to expand domestic defense production capabilities.
The Japanese technology company will produce core power supply units for the radar system, which contains more than 1,200 such components. The systems are scheduled for installation aboard Japan Self-Defense Forces Aegis-equipped vessels in 2027 and 2028, with initial deployments using Lockheed-made components before transitioning to Fujitsu’s parts for replacements.
The arrangement comes as Japan approved a record ¥8.7 trillion ($55 billion) defense budget for 2025, marking the 13th consecutive annual increase. Tokyo aims to eventually double military spending to around ¥10 trillion ($63 billion), which would make it the world’s third-largest defense spender behind the United States and China.
Fujitsu reported consolidated revenues of ¥3.6 trillion ($23 billion) for the fiscal year ended March 31, 2025. The company’s entry into defense manufacturing reflects Japan’s broader strategy to reduce reliance on foreign military suppliers while building up its domestic defense industrial base.
Lockheed Martin already delivered the first SPY-7 radar antenna to Japan’s Ministry of Defense in January, part of the country’s response to what officials describe as the most severe security environment since World War II.
