The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting proposals for the procurement of new manufacture spare parts, identified as "17--NRP,STRAINER,SUCTIO." This procurement is a sole source requirement, indicating that the government does not possess sufficient data to contract with any source other than the current approved supplier. The items are critical for aircraft ground servicing and require government source approval prior to award, necessitating that potential bidders submit detailed information as outlined in the NAVSUP WSS Source Approval Brochure. Interested parties should direct inquiries to Danielle Junod at danielle.m.junod.civ@us.navy.mil, and proposals must remain valid for a minimum of 120 days following submission.
