The Department of Defense, through the NAVSUP Weapon Systems Support office, intends to procure one unit of an Air Cycle, specifically NSN 1650-016647237-H5, from Sikorsky Aircraft Corporation, the sole source for this item. This procurement is critical as the Air Cycle is an essential component for aircraft hydraulic, vacuum, and de-icing systems, and no alternative sources are approved to manufacture this part due to the lack of available data and drawings. Interested parties are encouraged to submit capability statements or proposals within 45 days of this notice, with the anticipated award date set for February 2024. For further inquiries, contact Lauren N. Phillips at lauren.n.phillips@navy.mil or by phone at (215) 697-6566.
