The DD(X) National Team, led by Northrop Grumman Corporation, has introduced the U.S. Navy's first shipboard active phased array multifunction radar, AN/SPY-3, designed to meet all horizon search and fire control requirements for the 21st century fleet. The SPY-3 multifunction radar, designed by Raytheon Integrated Defense Systems and introduced in a ribbon-cutting ceremony here yesterday, combines the functions provided by more than five separate radars currently aboard Navy surface combatants. SPY-3 supports new ship design requirements for a reduced radar cross section, significantly reduced manning requirements, and total ownership cost reduction. "We've been making tremendous progress with all of the critical technologies in the DD(X) program," said Capt.
