The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support MECH, is seeking to procure four units of an Uninterruptible Power Supply (NSN 7H-6130-016939440) under a presolicitation notice. The procurement is limited to a single source due to the Government's lack of adequate data or rights to data necessary for competitive contracting. These electrical converters are critical for ensuring uninterrupted power supply in various military applications. Interested parties are encouraged to submit their capabilities and interest to the primary contact, Rachael Costanzo, at RACHAEL.L.COSTANZO.CIV@US.NAVY.MIL, within 15 days of this notice, as the Government intends to negotiate with only one source under FAR 6.302-1.
