USSOCOM’s Technology Application Contracting Office is conducting market research via a sources sought notice to assess qualified sources for an increased scope of Collins Aerospace Life Cycle Contractor Support Services for the Tactical Mission Networking program. The Government intends to award a sole-source modification to incumbent Collins Aerospace (Cedar Rapids, IA) under FAR 6.302-1 because it lacks the technical data needed for full and open competition. The modification would increase procurement of new core components and the number of items actively managed and repaired under LCCS. This is not an RFP, and interested capable sources may submit a Statement of Interest and Capability (limited to 10 pages) demonstrating qualifications and relevant past performance. NAICS code 334511 applies, with a standard business size of 1,350 employees, and sources may recommend other NAICS codes.
