The Department of Defense, through the Defense Logistics Agency, is seeking to procure turbochargers and similar replacement parts, specifically NSN 7H-2950-123960720, with a total quantity of 28 units. The procurement is intended to be a sole-source contract with Rolls-Royce Solutions America Inc. as the approved supplier, due to the government's determination that it is uneconomical to acquire the data or rights necessary for competitive sourcing. These parts are critical for maintaining operational readiness and performance of military equipment. Interested parties may submit their capabilities or proposals within 45 days of this presolicitation notice, and inquiries should be directed to Cerrill McMeekin at CERRILL.MCMEEKIN@DLA.MIL.
