The government intends to negotiate with only one source for a quantity of two units of this NSN, with delivery on an FOB origin basis. The item is flight critical and requires Government source approval; only previously approved sources have been solicited, and new sources must go through qualification procedures that cannot delay award. Interested parties may submit capability statements or quotes, which the government will consider for determining whether to conduct competitive procurement. The government is not using commercial acquisition procedures, but interested parties may identify commercial item capabilities. This notice is for information and planning purposes only, not a request for competitive quotes.
