Griffon Corporation (NYSE:GFF), announced today that Telephonics Corporation, its electronic information and communication systems subsidiary, received a $71.5M order from Lockheed Martin Systems Integration - Owego for development of increased capabilities and functional enhancements to the AN/APS-147 Multi-Mode Radar (MMR) and IFF Interrogator Systems for the U.S. Navy's MH-60R Maritime Strike Helicopters. The program, called Automatic Radar Periscope Detection and Discrimination (ARPDD), will develop a next-generation Telephonics AN/APS147 multi-mode radar that will feature new capabilities to detect very small, low visibility targets using advanced algorithms and additional hardware and software improvements. The contract is a follow-on to an existing $17.5M Navy development contract awarded to Telephonics in 2006.

"This is a very important enhancement to the already extremely capable AN/APS-147 MMR. ARPPD will bring unprecedented performance against these most difficult contacts and enable new mission capabilities in the Maritime Strike Helicopter," said Joseph J. Battaglia, President of Telephonics. "We are proud to be a part of this important program and look forward to continuing our support to Lockheed Martin and to the U.S. Navy."

Telephonics Radar Systems Division is a world leader in lightweight, highperformance, multi-mode maritime surveillance systems. In addition to the AN/APS-147, Telephonics produces the AN/APS-508 for the Canadian CP140 Aurora aircraft, the APS-143C(V)3 for various U.S. and International operators including the U.S. Coast Guard, the RDR-1700B lightweight MMR now in service with the Japanese Coast Guard, and a range of search and rescue and weather radar for civil and military applications.
