AN/SPY-3 Tracks Drone, Reaches Milestone (May 4)

TEWKSBURY, Mass. --- The U.S. Navy’s first shipboard active phased array multifunction radar, AN/SPY-3, successfully achieved a significant performance milestone recently during testing at the Navy’s Land Based Test Site at Wallops Island, Va.

The Raytheon-designed radar performed precision track of a low altitude BQM-74 test drone during multiple inbound and outbound flights. The SPY-3 is being developed as part of the DD(X) program, headed by Northrop Grumman Ship Systems.

The SPY-3 is an active phased array X-band radar designed to meet all horizon search and fire control requirements for the 21st century fleet. The multifunction radar combines the functions provided by more than five separate radars currently aboard Navy combatant ships. SPY-3 supports new ship-design requirements for reduced radar cross-section, significantly reduced manning requirements, and total ownership cost reduction. The SPY-3 radar is being designed for the DD(X) class of surface combatants, the transformational aircraft carrier CVN-21, and the Navy’s next-generation amphibious warfare ships. Raytheon serves as the electronic and weapons systems integrator for DD(X) as a subcontractor to Northrop Grumman Ship Systems.

Development of the SPY-3 began in 1999 and was delivered to the Navy’s test site in early 2003 for its two-year testing program. Work was performed at Raytheon’s Integrated Air Defense Center in Andover, Mass., its Surveillance and Sensors Center in Sudbury, Mass., and its Integrated Defense Systems Headquarters in Tewksbury, Mass.

Based in Tewksbury, Mass., Integrated Defense Systems is Raytheon’s leader in mission systems integration. With a strong international and domestic customer base, including the U.S. armed forces and the U.S. Missile Defense Agency, Integrated Defense Systems provides integrated solutions for the air, surface and subsurface battlespace.
