This is a procurement for five aircraft air seals, which are a critical safety item, with delivery required on or before February 15, 2027. The government intends to solicit and negotiate with only one or a limited number of sources, specifically noting Raytheon Technologies Corporation as an approved source. A previous contract for similar items listed a unit price of $3,506.95. The notice states this is not a request for competition, but proposals received within 45 days of the synopsis publication will be considered. Specifications are incomplete, and the acquisition involves export-controlled technology with a military application.
