This sources sought is for market research only to identify capable sources and market conditions for software programming support for the MPST computer program; no proposals are requested or accepted and no contract will be awarded from this synopsis. Contractor personnel must be eligible for Top Secret/SCI/SAP access with a current adjudicated background investigation and must be familiar with MPST software programming, RQ-170 aircraft survivability, Blue/Gray/Red ground and airborne threat systems, and Suppressor modeling. Work will be performed primarily at the ARA facility in Albuquerque, NM, with periodic on-site visits to Creech AFB, NV, Palmdale, CA, Littleton, CO, and other classified locations as determined by the government. The period of performance is one base year plus four option years beginning 30 September 2026; support from the contractor’s facility must be provided within one business day of request, and modifications generally within 14 days of a COR request unless mission needs require a shorter timeline. The effort is under NAICS 541511, and the market survey seeks interest and qualifications from small businesses, including 8(a), HUBZone, SDVOSB, and EDWOSB concerns.
