The Defense Logistics Agency at Redstone Arsenal, Alabama, is conducting market research to identify qualified manufacturing/supply sources for a compressor-dehydrator (NSN 4440-01-388-5626, PN 11474244) supporting the Patriot Weapons System under NAICS 333994 with a 500-employee size standard. The acquisition is currently being pursued under FAR 6.302-1(a)(2) due to a limited number of responsible sources, and all offerors must meet prequalification requirements. The government encourages all business types—including 8(a), small/disadvantaged, SDVOSB, HUBZone, and women-owned small businesses—to identify themselves and seek source approval through the Army DEVCOM Aviation & Missile Center’s System Readiness Directorate. The contractor will be responsible for recurring and nonrecurring engineering to become a qualified source and for all manufacturing/production aspects, including supply chain management, logistics, forecasting, long-lead procurement, obsolescence, and final delivery. Foreign firms must process solicitation requests through their embassies, and this sources-sought notice is for informational/planning purposes only, imposes no government commitment, and provides no funds for response preparation.
