Telephonics Awarded ARPDD Retrofit Program

June 21, 2017

Telephonics Corporation, a wholly owned subsidiary of Griffon Corporation (NYSE: GFF), announced today that it has been awarded year two of a multi-year, Indefinite Delivery Indefinite Quantity (IDIQ) production contract valued at approximately $37M from Lockheed Martin for AN/APS-153(V)1 radar retrofit kits with Automatic Radar Periscope Detection and Discrimination (ARPDD) capability. As part of the U.S. Navy’s ARPDD Retrofit Program – Phase Three, year two, this award is a follow-on phase to a previously awarded multi-year contract. Telephonics ARPDD systems will be installed on the U.S. Navy’s MH-60R Sea Hawk helicopters, providing advanced maritime and littoral surveillance.

The AN/APS-153(V)1 is the successor to the AN/APS-147 and in addition to ARPDD, provides other advanced search capabilities including small target detection, Inverse Synthetic Aperture Radar (ISAR) imaging and a fully integrated Identification Friend or Foe (IFF) interrogator. Initial deliveries of the retrofit kits begin in spring 2018 and kits include one Radar Data Processor (RDP), one Antenna Pedestal (AP) and one Receiver Transmitter (RT).

“Telephonics is extremely proud to continue our support of this critical naval program, providing a surveillance system designed to meet the demanding mission needs of U.S. Navy crews around the globe,” said Mr. Kevin McSweeney, President of Telephonics. “The AN/APS-153(V)1 will provide enhanced capabilities to the Navy, enabling increased maritime and littoral domain awareness in all types of weather conditions, both day and night.”
