DLA Aberdeen, on behalf of Army ILSC/SCMD/SSD, intends to acquire PATRIOT Missile Defense System parts, specifically electrical generator parts kits for 400 Hz generator sets and a power distribution-reference signal group (NSN 5840-12-429-1386, P/N 420.02.0899) for PATRIOT radar subsystems. The Government does not possess or release the technical data package for these parts. The electrical parts kit NSN 6115-01-691-9801 was last purchased on 9/15/2025 in a quantity of 60, and the power distribution item was last purchased on 9/23/2026 in a quantity of 72. This is a sources sought/market research announcement, not a request for quote or proposal, and no contract will be awarded or costs reimbursed based on responses; it is intended to determine whether responsible sources exist and inform acquisition strategy, including competitive or Small Business set-aside decisions. Interested sources should email documentation showing capability to manufacture or supply the same or similar parts/services—such as a questionnaire, drawings, test results, past Government/commercial contract information, data rights, company name, CAGE code, and technical point of contact—to the listed points of contact, with no phone inquiries accepted.
