Lockheed Martin Takes Next Step Toward PAC-3 MSE Integration with Aegis Weapon SystemMOORESTOWN, N.J., July 10, 2023– For the first time, Lockheed Martin’s Patriot Advanced Capability – 3 (PAC-3) Missile Segment Enhancement (MSE) interceptor successfully communicated with the AN/SPY-1 Radar, a key component in the Aegis Weapon System. “This successful test is a major step forward to fully integrate PAC-3 MSE into the Aegis Weapon System,” said Tom Copeman, vice president, Naval Systems, Lockheed Martin Missiles and Fire Control. The SPY-1 radar operates on an S-band frequency, which required Lockheed Martin to convert PAC-3 MSE’s existing dual-band datalink to a tri-band datalink to communicate at S-band. This successful test, funded internally by Lockheed Martin, validates the initial integration of this capability. In 2022, Lockheed Martin opened a new 85,000-square-foot building expansion at the Camden, Arkansas, facility to support increased production capacity for PAC-3 MSE.
