The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of a flight-critical commercial item identified by NSN 1R-1680-LLF02K511-P8, with a quantity of one unit required for delivery FOB origin. This item is classified under miscellaneous aircraft accessories and components, and it necessitates government source approval prior to contract award due to its critical nature and the inadequacy of available technical data for full and open competition. Interested vendors must provide the necessary documentation for source approval along with their proposals, as offers lacking this information will not be considered. For inquiries, Katlyn M. Galetto can be contacted at (215) 697-6549 or via email at KATLYN.M.GALETTO.CIV@US.NAVY.MIL, with a proposal submission deadline of 45 days from the notice publication date.
