The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of four units of the Panel Assembly, Airc, identified by NSN 1R-1680-015320857-V2 and reference number 901-069-300-104. This procurement requires government source approval prior to contract award due to the flight-critical nature of the item, and only previously approved sources will be considered for this solicitation. Interested parties must submit the necessary documentation for source approval along with their proposals, as failure to provide the required information will result in disqualification. The deadline for proposal submissions is 45 days from the publication of this notice, and all inquiries should be directed to Taylor M. O'Connor at (215) 698-2198 or via email at TAYLOR.M.OCONNOR2.CIV@US.NAVY.MIL.
