The Department of Defense, through the NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 13 units of a flight-critical vane axial fan, identified by NSN 7R-4140-013293428-VH. This procurement requires government source approval prior to contract award, as the technical data available does not support full and open competition, and only previously approved sources will be considered. The item is essential for operational readiness, and potential suppliers must submit detailed documentation regarding their production capabilities and prior approvals, as offers lacking the necessary information will not be considered. Interested parties should contact Svitlana Shvets at (215) 697-6278 or via email at svitlana.shvets@navy.mil for further details and guidance on the submission process.
