The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support Mechanics, is seeking to procure a power supply under the presolicitation notice titled "61--POWER SUPPLY, IN REPAIR/MODIFICATION OF." The procurement involves a single source contract for one unit of NSN 7H-6130-015425974-GL, with delivery required to DLA Distribution in New Cumberland, PA. This power supply is critical for military applications, and the government has determined that it is uneconomical to reverse engineer or purchase the data rights for this part. Interested parties are encouraged to submit their interest and capability statements within 45 days of the notice, with the primary contact for inquiries being Heather R. Jones at heather.jones2@navy.mil. The opportunity is set aside for small businesses, and the government will consider all proposals received within the specified timeframe.
