Telephonics Corporation, a wholly owned subsidiary of the Griffon Corporation (NYSE:GFF); announced today that its Radar Systems Division received a $99.3M follow-on order from Lockheed Martin for the purchase of AN/APS-147 Multi Mode Radar System and subsystem spares. The radar includes a fully integrated Identification Friend or Foe (IFF) interrogator system.

The integrated system is deployed on U.S. Navy MH-60R multi-mission helicopters whose principal mission is to protect the fleet from submarines and surface vessels. The radar provides the helicopter with long-range search, imaging and tracking of surface vessels, a periscope detection mode, and the IFF to identify other aircraft in flight.

The systems and spares are part of a multi-year contract awarded to Lockheed Martin Systems Integration in Owego, NY in 2007 to integrate the avionics and mission systems onto 139 MH-60R helicopters through 2013.

"The high reliability of the AN/APS-147 Radar/IFF subsystem increases the availability and mission effectiveness of the MH-60R helicopter fleet wherever it is deployed around the world," said Joseph J. Battaglia, president of Telephonics. "We look forward to a long and successful program supporting Lockheed Martin and the U.S. Navy."
