Lockheed Martin won an $311 million follow-on production contract from the U.S. Army to provide Arrowhead systems, an electro-optical system for AH-64 Apache combat helicopter pilots. The agreement includes production of 158 Arrowhead kits for some of the remaining U.S. Army and foreign military sales inventory, as well as wartime replacement Modernized Target Acquisition Designation Sight/Pilot Night Vision Sensor (M-TADS/PNVS) systems for new aircraft. The contract also includes spares for both. Lockheed Martin said the kit modernizes the U.S. Army’s TADS/PNVS by upgrading the infrared sensors and associated electronics. Lockheed Martin will produce Lot 4 in Orlando and Ocala, Fla. The final deliveries will occur in December 2009. For related news
