The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 104 specialized shipping and storage containers, identified by NSN 6K-8145-015637030-YR. This presolicitation requires that all bidders be previously approved sources due to the flight-critical nature of the item, and any new sources must submit comprehensive documentation for source approval alongside their proposals. The successful contractor will be responsible for delivering the containers FOB Origin, and the award will only be made if the offeror meets all qualification requirements at the time of award. Interested parties should contact Patrick Horan at (215) 697-0275 or via email at PATRICK.J.HORAN1@NAVY.MIL for further details and to ensure compliance with the necessary submission requirements.
