This is a sole-source procurement for 2 units of NSN 7R-6110-016670469-H5, with delivery on an FOB origin basis. The item is flight critical and requires Government source approval prior to award, so only currently approved sources are being solicited. If you are not an approved source, you must submit the detailed source approval information from the NAVSUP WSS brochures with your proposal, and offers lacking that documentation will not be considered. New source approval typically cannot be completed in time to allow for award, so approval may not be granted before the Government’s needs are met. The acquisition may also be subject to Free Trade Agreements and other trade agreement provisions depending on the solicitation clauses included.
