Telephonics Corporation, a wholly owned subsidiary of the Griffon Corporation (NYSE:GFF); announced today that it has been awarded a Multi-year contract from the Boeing Company for the Intercommunication System (ICS) for the CH-47F Chinook helicopter.

Telephonics will supply its advanced Secure Digital Intercommunications (SDI) system. SDI is a TEMPEST-qualified ICS that manages all of the crew audio communication and radio/navigation resources aboard the aircraft. Telephonics has been supplying the SDI ICS to Boeing since the first CH-47F was built.

The contract covers the delivery of production aircraft to the U.S. Army from 2009 to 2013 and options for systems for spares. U.S. Government or direct commercial sales are also included in the contract.

Telephonics' SDI has been selected by the U.S. Army as the Common Digital Intercommunication System. In addition to its use in the Chinook cockpit, it is being installed on all U.S. Army UH-60M Black Hawks, the UH-60M COMHAWK Command and Control helicopter and the MH-47's and MH-60's of the 160th Special Operations Aviation Regiment (Airborne). The U.S. Coast Guard is also participating in the program and is having SDI incorporated into all of its MH-60T Jay Hawk helicopters. Use of the common ICS will lead to savings in logistics and training and an improvement in aircraft readiness.
