The Department of Defense, through the NAVSUP Weapon Systems Support office, is seeking to procure a sole source item, specifically the CONNECTOR-SWITCH AS, under the National Stock Number (NSN) 7R-5999-013013224-LA. The procurement involves a quantity of one unit, with delivery terms set as FOB Origin, and is intended for a Foreign Military Sales (FMS) buy for Australia. This item is critical as it is the only known source available from L3Harris Technologies Inc., the Original Equipment Manufacturer, and no drawings or data are available for alternative sourcing. Interested parties must submit their capability statements or proposals to the primary contact, Michael J. Keith, via email at michael.j.keith40.civ@us.navy.mil, within 45 days of this notice, as the government intends to negotiate with only one responsible source. This procurement is not set aside for small businesses and will utilize electronic procedures for solicitation.
