Lockheed Martin will build shipboard Aegis air defense and radar systems for Navy cruisers and destroyers

WASHINGTON- The on-board electronics experts at Lockheed Martin Corp. will build and deliver Aegis combat systems for U.S. Navy cruisers and destroyers as part of a $92.5 million order announced Monday.

Naval Sea Systems Command Washington officials direct the Lockheed Martin Rotary and Mission Systems segment in Moorestown, NJ, to design, develop, integrate, test, and deliver Aegis Advanced Capability Build (ACB) 20.

The Aegis Combat System uses powerful computers and radars to track and guide weapons to destroy enemy targets. More than 100 Aegis-equipped ships have been deployed in five navies around the world. Aegis, not an acronym, refers to the shield of the mythical Greek god Zeus.

Aegis, developed in the 1980s, integrates the AN/SPY-1 radar, MK 99 fire control system, weapons control, command and decision suite and the SM-2 Standard missile family, which includes the basic standard RIM-66, the RIM-67 extended range missile and the newer RIM-161 designed to counter ballistic missiles.

The Aegis air defense system was developed by RCA’s Missile and Surface Radar Division, which after a series of acquisitions became part of Lockheed Martin in 1995.

Lockheed Martin engineers are installing additional capabilities into the Aegis weapon system, such as Ballistic Missile Defense (BMD) 5.1, which incorporates a 21-inch-diameter variant of the SM-3 missile called the SM-3 Block IIA. BMD 5.1 will also improve Aegis data links to enable remote track data engagement.

Lockheed Martin’s work also integrates the SPQ-9B surface search and fire control radar into the Aegis weapon system. The SPQ-9B detects and tracks incoming targets at sea level, water surface for fire engagement or navigation.

The work also integrates the Lockheed Martin MH-60R Seahawk anti-submarine warfare (ASW) helicopter into the Aegis system, and improves the electronic warfare (EW) capabilities of the system through the electronic warfare enhancement program surface (SEWIP).

Lockheed Martin experts will also expand Tactical Data Link (TDL) capability with Link 22 on the Aegis system for better interoperability and improve onboard training capability through Total Ship Training Capability (TSTC).

Previous Aegis upgrades installed commercial off-the-shelf (COTS) computers to enhance combat capabilities such as simultaneous anti-aircraft warfare and ballistic missile defense.

On this contract amendment, Lockheed Martin will perform the work in Moorestown, NJ, and is expected to be completed by December 2022. For more information, contact Lockheed Martin Rotary and Mission Systems online at, or Naval Sea Systems Command at
