The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking a contractor for the repair and modification of transformer assemblies, identified by NSN 7H-5950-014382603-GL. The procurement involves a quantity of six units, which will be delivered to NAVSUP FLC Jacksonville in Florida, and is classified under the PSC code 5950 for coils and transformers. This contract is crucial as the government does not possess the necessary data or rights to procure these parts from alternative sources, making it essential to engage a qualified vendor for this specific requirement. Interested parties are encouraged to contact Christian D. Spangenberg at (717) 605-5192 or via email at CHRISTIAN.SPANGENBERG@NAVY.MIL, with proposals due within 45 days of the notice publication, as the government intends to negotiate with only one source under FAR 6.302-1.
