Their work directly enables base operating support and environmental compliance, aligning with the agency’s strategic priorities in resilience, modernization, and force readiness. Sithideth maintains consistent working relationships with a core group of established contractors, including KANAGAWA NABCO PTY.

These partnerships reflect a preference for proven, high-capacity vendors capable of delivering complex, multi-site services across remote and forward-deployed locations.

Sithideth’s procurement portfolio is entirely non-set-aside, with 100% of awards issued under full and open competition.
