The Department of Defense, specifically the Department of the Army, is seeking sources for TACAN 154 Repair Services, which are critical for the Army fleet Blackhawk UH-60A/L helicopters. The procurement involves supplying new TACAN units, with a focus on ensuring that any items meet airworthiness certification and function satisfactorily for their intended military purposes. The Government does not possess the technical data package for the parts, and interested parties are required to submit documentation demonstrating their capability to supply the necessary items by January 9, 2026.
