McKINNEY, Texas, June 6, 2006 /PRNewswire/ -- The U.S. Navy has granted new nomenclature -- AN/APY-10 -- to Raytheon Company's maritime surveillance radar for the P-8A Multi-mission Maritime Aircraft (MMA).

Typically, new nomenclature results when systems change significantly. Although the APY-10 has all the capabilities of the Navy's AN/APS-137 maritime surveillance radar, Raytheon Space and Airborne Systems (SAS) believed extensive modifications to the P-8A radar justified a request for new nomenclature.

The APY-10 will display weather information in color, provide better performance in track-while-scan and target detection modes, and allow full on-line direction by Boeing's Mission Control and Display System for the P-8A. The APY-10 will also be substantially smaller and lighter that the APS-137.

"APY-10 represents improved technology and expanded mission capability for the P-8A and our Boeing and Navy customers," said Craig Young, chief engineer for the P-8A MMA Radar program. "The APS-137 certainly has name recognition in the Navy and international maritime surveillance community, and it is known for its high-performance detection and imaging capabilities. However, there are too many innovations associated with APY-10 for the old nomenclature to be appropriate."

Raytheon delivered the APY-10 software design lab (radar) protocol emulator to Boeing in February and expects to finish construction in July of a mission systems integration laboratory for the P-8A radar.

Raytheon SAS is the leading provider of sensor systems giving warfighters the most accurate and timely information available for the network-centric battlefield. With 2005 revenues of $4.2 billion and 13,000 employees, SAS is headquartered in El Segundo, Calif., with additional facilities in Goleta, Calif.; Forest, Miss.; Dallas, McKinney and Plano, Texas; and several international locations.

Raytheon Company (NYSE: RTN), with 2005 sales of $21.9 billion, is an industry leader in defense and government electronics, space, information technology, technical services, and business and special mission aircraft. With headquarters in Waltham, Mass., Raytheon employs 80,000 people worldwide.

Note to Editors:

American military equipment is designated by the Department of Defense according to the Joint Electronics Type Designation System (JETDS), which indicates the applicable platform and capabilities of a particular system. While the AN/ prefix remains from the previously used Joint Army-Navy Nomenclature System, APY-10 can be explained by JETDS as follows:

A - indicates that the equipment is for installation on a piloted aircraft.

P - means the equipment is a radar.

Y - indicates Surveillance (search, detect and multiple target tracking) and Control (fire and air), whereas the S in APS-137 stands for Detecting/Range and Bearing, Search. This third letter indicates the equipment's purpose, and the change from S to Y reflects the P-8A radar's expanded mission application.

  10 - sequential number for next AN/APY provided by the Navy.
