The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 16 units of the Motor, Alternating Current (NSN 7R-6105-011820435-EY). This procurement is critical as the item is flight critical, and the government requires source approval prior to contract award, limiting solicitation to previously approved sources only. Interested parties must submit comprehensive documentation demonstrating their capability to produce the item, as the government does not own the rights to the necessary technical data for alternative sourcing. Proposals must be submitted within 45 days of this presolicitation notice, and inquiries can be directed to Katlyn M. Galetto at (215) 697-6549 or via email at katlyn.galetto@navy.mil.
