PPGI makes missile-warning sensors for ATK

NORTHVALE, N.J., 30 Sept. 2005. Photonic Products Group, Inc. announced today that its INRAD business unit has been awarded a series of follow-on production contracts in recent months from ATK Missile Systems' Clearwater, Fla. facility.

PPGI will deliver more than 5,500 of two types of ultra violet (UV) waveband optical filter elements for ATK's upgraded AN/AAR-47 Missile Warning Systems.

ATK Missile Systems, a division of Alliant Techsystems, is the developer and prime contractor for production of this enhanced performance system for protection of low and slow-flying aircraft from a variety of missiles. In low-rate production beginning in 2002 and in high rate production at present, these components will be incorporated into systems for U.S. Navy, Air Force, and allies' aircraft. The dollar value of the contract was not disclosed.

The subject ultra-violet filters are specialty optical components made from high purity and high uniformity single-crystals of a proprietary material which absorbs all wavelengths except those in the UV region of the electro-magnetic spectrum. This synthetic crystal material was developed by INRAD expressly for such applications, has the highest temperature stability and mechanical stability of any alternative material, and is patented for this end-use. These filters are a key optical component of airborne electro-optical missile warning sensors.

INRAD has been the sole provider of these elements for the present generation of system for slow-flying aircraft, and had previously produced many thousands for the prior generation of systems. INRAD as well provides proprietary UV filters for systems that protect high-speed aircraft.

Dan Lehrfeld, president and CEO of Photonic Products Group commented, "We are pleased to be a critical component supplier to the ATK team, a customer that makes our team a true 'supply chain partner.' These recent orders, in the aggregate, represent the highest annual buys from us to date on this program, and cover deliveries that commenced in July. Our team is proud to have contributed, at least in part, to making ATK's newest AN/AAR-47 system a success."
