This Sources Sought Synopsis is market research, not a solicitation, to assess responsible sources and a possible small-business set-aside strategy for repair of NSN 5840-01-659-4499. The contractor must furnish all facilities, parts, materials, equipment, and services to inspect and, if necessary, restore the item to serviceable condition under a firm-fixed-price contract with a 320-day period of performance after receipt of order. The requirement is limited-source because the Government lacks data/software rights and reverse engineering is uneconomical; the approved OEM is Applied Systems Engineering Inc. (CAGE 3Z966), located in Benbrook, Texas. The applicable NAICS code is 811210 with a $34M average annual receipts size standard, and the Government seeks responses from all small-business categories including 8(a), SDVOSB, HUBZone, and WOSB. Interested parties should submit a capability statement (PDF preferred, maximum five pages) covering business status, similar experience, pricing/historical pricing, GFP handling, teaming arrangements, required data/documents, top risks, and expected proposal preparation time.
