The total value of the agreement could reach a maximum of $3 billion. No funding was launched at the time of signing, with individual production batches to be ordered under separate implementing contracts.
The agreement remains valid until the end of June 2031. This opens the way for future orders, including potential purchases by export customers through the U.S. Foreign Military Sales procedure.
Serial deliveries of Sentinel A4 radars from the initial production batch began in 2022. The manufacturer is currently working under a second agreement covering 19 units.
The Sentinel A4 radars are intended to improve situational awareness by detecting and tracking airborne objects. These include manned and unmanned aircraft, cruise missiles, and artillery and mortar rounds.
The radar’s new operating modes are intended to allow it to track three types of threats at the same time. The system is also planned to be integrated with the Integrated Battle Command System, known as IBCS.
According to Lockheed Martin’s concept, advanced technical solutions used in the AN/MPQ-64 Sentinel A4 and AN/TPY-4 radars may be attractive for U.S. armed forces and export customers. The framework agreement therefore supports both domestic production needs and possible future international demand.
The Sentinel A4 program is linked to efforts to strengthen air and missile defense detection and tracking capabilities. The framework structure gives the Department of War a route to place production orders over several years while keeping funding tied to future implementing contracts.
