DZSP 21 LLC specializes in facilities support services and port and harbor operations, delivering mission-critical infrastructure sustainment for federal agencies. The contractor provides comprehensive base operations support, including facility maintenance, utilities management, fuel delivery, water and electrical services, and ship arrival/departure coordination. Their technical expertise lies in integrated logistics support for military and scientific maritime assets, ensuring seamless operational readiness through disciplined facility management and port infrastructure coordination. A key differentiator is their ability to execute complex, geographically dispersed operations under stringent federal compliance frameworks, particularly in austere or remote locations such as Guam. The company has established a consistent presence with the Department of Defense, delivering sustained base operations support for naval and military installations, including administrative reissuance and continuity of services under evolving contract structures. They also serve the Department of Commerce, specifically supporting NOAA’s research vessel operations through port services that require precise scheduling, environmental compliance, and real-time logistics coordination for scientific missions. Their primary industry focus is on NAICS 561210 (Facilities Support Services), where they deliver integrated facility sustainment, and NAICS 488310 (Port and Harbor Operations), where they provide specialized maritime support for federal vessels. This dual focus positions them as a niche provider of hybrid land-sea infrastructure services, particularly suited for defense and scientific agencies requiring coordinated operational support in isolated or high-tempo environments. DZSP 21 LLC is structured as a 2L entity headquartered in Chantilly, Virginia, with no public certifications on record. Their operational footprint is concentrated in U.S. defense and scientific maritime zones, with demonstrated capability to manage mission-critical infrastructure in geographically challenging locations. The company maintains a focused government market positioning centered on reliability, continuity of service, and technical execution in high-stakes federal environments.
