The Department of Defense, through the Defense Logistics Agency (DLA) Aviation at Philadelphia, PA, is soliciting proposals for the procurement of a pre-amplifier unit, classified under NAICS code 336413, which pertains to Other Aircraft Parts and Auxiliary Equipment Manufacturing. This solicitation emphasizes the need for government-approved sources, as proposals from non-approved suppliers will be deemed technically unacceptable; thus, authorized distributor letters must accompany submissions from dealers or distributors. The procurement is critical for supporting military operations, as the components will be delivered to foreign military sales customers, retaining ownership throughout their lifecycle. Interested vendors should direct inquiries to Malcolm Fils at 215-737-0422 or via email at MALCOLM.FILS@DLA.MIL, and must adhere to the submission guidelines outlined in the solicitation.
