Respondents must be capable of managing full production cycles including component procurement, inspection, testing, packaging, shipping, and addressing supply chain challenges such as diminishing manufacturing sources and long-lead parts acquisition, with potential responsibility for nonrecurring engineering costs to qualify as an approved source. The procurement is classified under Federal Stock Class 1650 and NAICS Code 336413, which carries a size standard of 1,250 employees. The place of performance is Tinker AFB, Oklahoma, and all communications must be directed to the designated workflow email, [email hidden].
