Respondents must demonstrate substantial nuclear-submarine industrial infrastructure, including certified graving or floating drydocks, heavy module fabrication shops, gantry crane systems, qualified shipbuilding design personnel, quality management systems, nondestructive testing capabilities, and certified welding procedures for submarine-grade steels and advanced non-ferrous alloys. Interested vendors must complete the attached assessment and submit it electronically through DoD SAFE; the notice is for market research only and does not constitute a solicitation or commitment to award a contract.
