On February 12, Lockheed Martin and Japanese technology company Fujitsu signed a contract for the initial procurement of components that supply power to the modular Subarray Suite (SAS), a critical element of the SPY-7 radar selected for the Japan Maritime Self-Defense Force’s (JMSDF) Aegis System Equipped Vessels (ASEV). A signing ceremony held in Tokyo formalized Fujitsu as a supplier of the SPY-7 Subarray Suite Power Supply Line Replaceable Unit (PS LRU). The PS LRU is a mission-critical naval radar assembly that delivers stable and regulated electrical power to the radar’s SAS modules, supporting reliable performance in demanding maritime operating conditions.
The contract follows a Memorandum of Understanding (MOU) signed in May 2025 covering supplier selection and industrial partnership arrangements for the SPY-7 program. Under that framework, this marks the first procurement agreement between the two companies. The SPY-7 radar, developed by Lockheed Martin, is based on a scalable gallium nitride (GaN) Active Electronically Scanned Array (AESA) architecture designed to support ballistic missile defense (BMD) and integrated air and missile defense (IAMD) missions.
