Request for Interested Manufacturers AN/ALQ-172 Redesigned LRU-4 Countermeasures Transmitter; NSN 5865-01-718-3672, PN 2688804G002, Redesigned LRU 8 Antenna Control Subassembly: NSN 5985-01-734-3532, PN 2624708G007, Redesigned LRU 21 Control, PN2680721G005

The United States Air Force is conducting market research to identify potential sources for the manufacture of the Radio Frequency Amplifier, AN/ALQ-172 Redesigned Line Replaceable Unit (LRU)-4 Countermeasures Transmitter, and Redesigned LRU-8 Phased Array Antenna. The AN/ALQ-172 is a countermeasure set used in various aircraft, and the redesigned LRU-4 and LRU-8 are critical components of this system. The Radio Frequency Amplifier is responsible for increasing the power of incoming RF signals, and the Redesigned LRU-4 and LRU-8 provide high-level amplification of Pulse Radar (PR), Pulse Doppler (PD) or Continuous Wave (CW) ECM signals. The Government intends to procure these items using Other Than Full and Open Competition as prescribed by FAR 6.302-1, Only One Responsible Source and No Other Supplies or Services Will Satisfy Agency Requirements. Key points to consider: • The original equipment manufacturer (OEM) for these items is L3Harris Technologies, Inc. • The Government does not own any data, drawings, schematics, or any other releasable technical data in support of this requirement. • L3Harris Technologies, Inc. is the only known source with adequate knowledge of the Redesigned LRU-4 and LRU-8 and its performance requirements, sufficient production level technical data, and necessary production level test equipment and capabilities needed to produce this item and ensure compatibility of the equipment at the ALQ-172 system level. • Interested parties may identify their interest and capability to respond to the requirement no later than 2 Feb 2026.
