CPI Aerostructures, Edgewood, N.Y., said Sikorsky Aircraft added new requirements to an existing long-term agreement for Hover Infra Red Reduction System (HIRRS) module assemblies, for use on the UH-60 Black Hawk helicopter. This contract is expected to satisfy Sikorsky's anticipated requirements through early 2009. There are two HIRRS assemblies used on each helicopter, and there are about 1,500 UH-60 Black Hawk helicopters currently using this HIRRS configuration. The initial order for the HIRRS assemblies, valued at $4.4 million, was awarded to CPI Aero in September 2006. The company said it anticipates additional requirements will be added during the term and total HIRRS requirements will ultimately have a value in excess of $20 million by the end of 2010.
