(17 June 2005 – Dayton Ohio) – Lockheed Martin (NYSE: LMT) recently awarded Spectral Systems Incorporated (SSI) a letter subcontract to begin work on the development of a sensor subsystem for the Aerial Common Sensor (ACS). ACS is the Army’s next generation airborne intelligence, surveillance, and reconnaissance (ISR) system. ACS will replace the Army’s Guardrail Common Sensor and Airborne Reconnaissance Low systems. Tentative plans also call for ACS to be used as a replacement for the Navy’s EP-3 reconnaissance platform.

SSI is providing Lockheed Martin with a modular, reconfigurable, state of art system. Under the SD&D phase, SSI will develop and deliver five mission ready systems as well as a Systems Integration Lab (SIL) unit. The System Development and Demonstration (SD&D) phase runs through 2007 followed by low rate initial production.

Dave Sharpin, chief engineer of SSI said, “We look forward to working with Lockheed Martin on the ACS program and are proud to be a member of their team. The ACS development leverages our technology into a new application that will fully utilize its performance and reconfigurability. We will provide Lockheed Martin and the US Army customer with a high performance and cost effective solution. As always, we are committed to technology advancement and satisfying our customer’s requirements, but more importantly, to getting the best equipment into the hands of our service men and women.”
