About this opportunity
The Defense Logistics Agency Aviation is preparing to conduct market research on sole-source production of up converter and down converter assemblies for the AN/ALQ-161 Electronic Warfare System installed on B-1B aircraft, with interested-manufacturer responses due October 23, 2026. The contracting office intends to award a sole-source contract to Spectrum Microwave (CAGE 60979) under FAR 6.302-1, Other Than Full and Open Competition, due to that firm's exclusive possession of the manufacturing-level Technical Data Package and configuration control by part number; the Government holds source control drawings but lacks the manufacturing data required for competitive production.
The requirement covers 54 up converters (NSN 5895-01-683-8777, P/N SM1138) and 36 down converters (NSN 5895-01-683-8776, P/N SM1137). Both items are dual-output double mixers specified by control drawings 037-003066 and 037-003100, respectively. A redesign and First Article Test were completed in 2024; this procurement is for production of the approved configurations only. Other interested parties may demonstrate capability and express interest by emailing Kellen Miliner (kellen.miliner.1@us.af.mil) no later than October 23, 2026. This is market research; no competitive solicitation is currently planned absent a successful alternate-source response.
Notice text
SUBJECT:
Market research is being conducted to identify potential sources that may possess the expertise, capabilities, and experience to meet the requirements for production of the following items:
ITEM DESCRIPTION
- NSN: 5895-01-683-8777
Nomenclature: Double Mixer, UP CONVERTER
Specification Control Drawing: 037-003066
Part Number: SM1138 (CAGE 60979)
Estimated Quantity: 54 each
- NSN: 5895-01-683-8776
Nomenclature: Double Mixer, DOWN CONVERTER
Specification Control Drawing: 037-003100
Part Number: SM1137 (CAGE 60979)

These items are used on the AN/ALQ-161 Electronic Warfare System installed on the B-1B aircraft. A redesign of these configurations and First Article Testing was successfully completed in 2024. This requirement is for production of the approved configurations.
Impediment to Competition:
The Original Equipment Manufacturer (OEM) is Spectrum Microwave (CAGE 60979), which maintains configuration control by part number. The Government possesses source control drawings but does not own the manufacturing-level Technical Data Package (drawings, schematics, or other releasable manufacturing data) for these items. As a result, Spectrum Microwave (CAGE 60979) is the only known source with adequate knowledge and possession of the required technical data and capabilities needed to produce these items and ensure compatibility with the higher-level assembly.
INTEREST
