The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of two Ice Detector Probes (NSN 7R-1680-015854864-P8, REF NR 0871BN3-10). This procurement involves a commercial/non-developmental item that is critical for flight operations, requiring government source approval prior to contract award due to its importance and the inadequacy of available technical data for full and open competition. Interested vendors must provide necessary documentation for source approval along with their proposals, as offers lacking this information will not be considered. For further inquiries, interested parties can contact Marisa L. Tetkowski at (215) 697-2644 or via email at MARISA.TETKOWSKI@NAVY.MIL.
