Representatives from Missile Defense Agency (MDA) and U.S. Navy Aegis Technical Representative (TECHREP) witnessed a successful Mid-Release 2 Demonstration in Moorestown, New Jersey. The software release for the Japanese J7.B Aegis Weapon System will allow Japan to have a ballistic missile defense (BMD) using the ASEV.

During the demonstration, Aegis Baseline J7.B with SPY-7 proved its ability to engage ballistic missiles using the SM-3 Block IIA interceptor.

Aegis Baseline J7.B successfully implemented critical fire-control functions, including missile acquisition, guidance commands, and two-way missile communications, simultaneously with SPY-7 radar operations.

J7.B with the SPY-7 showed that it has the capability to properly search and track very large raids of BMD threats.
