VACCO Industries has been awarded a five-year contract worth up to $35 million to supply T-700 anti-icing valves for use on U.S. Army UH-60 series Black Hawk helicopters. Based on the Army's historical usage patterns for this product, and previous T-700 contract quantities delivered, VACCO expects to receive additional purchase orders for the full quantity of products over the term of the contract. VACCO's anti-icing valves are designed to provide hot airflow for engine anti-ice protection during flight and to bleed air from the engine during start-up. T-700-powered Black Hawk helicopters are used extensively by the U.S. Army domestically and in overseas operations. T-700 engines are also used on the U.S. Navy's Naval Hawk and the U.S. Coast Guard's Seahawk variations of the Black Hawk, as well as the Army's AH-64 Apache helicopters.
