The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting proposals for the procurement of six Mission Relay Assemblies (NSN: 7RH 1680 015752561, P/N: 96550-01031-042). This sole source requirement necessitates that interested vendors provide comprehensive data as outlined in the NAVSUP WSS Source Approval Brochure, as the government lacks sufficient data to contract with sources other than the current supplier. The procurement is critical for maintaining operational capabilities, and proposals must be submitted via email to Dana Scott at dana.l.scott14.civ@us.navy.mil by the specified deadline. For further inquiries, interested parties can contact Dana Scott at 215-697-0273.
