The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting bids for the procurement of new manufacture spare parts, specifically a cylinder tensioner, classified under NAICS code 336413. This procurement is critical as the components are designated as Flight Critical, requiring engineering source approval from the Naval Air Systems Command, which means only approved manufacturers will be eligible for award. Interested vendors must submit a Source Approval Request along with their proposals, which will be evaluated based on lead time, price, past performance, and capacity. The closing date for submissions is set for 2:00 PM EST on the specified deadline, and inquiries can be directed to Alexis Healy at 215-697-1143 or via email at Alexis.Healy@navy.mil.
