The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 10 units of the Antenna Assembly (NSN 7R-5985-015874866-P8, REF NR 131K876G01). This procurement requires government source approval prior to contract award due to the flight-critical nature of the item and the inadequacy of available technical data for full and open competition. Interested vendors must provide detailed technical data and documentation as outlined in the NAVSUP WSS Source Approval Information Brochures, as offers lacking this information will not be considered. For inquiries, interested parties can contact Sarah E. Crompton at (215) 697-5809 or via email at sarah.crompton@navy.mil.
