What DZSP 21 does
DZSP 21 LLC is a Delaware-incorporated, privately held government services contractor and a subsidiary of Amentum that delivers Base Operations Support (BOS) services to the U.S. military on Guam. Founded in 2005 and headquartered at Naval Base Guam with a mailing address in Hagåtña, the company operates under a single integrated service platform rather than a modular product offering, performing port operations support, facilities maintenance and operations, transportation fleet management, and utilities operations (high-voltage power distribution, demineralized water production, potable water treatment and distribution, wastewater collection and treatment) across eight installations: Naval Base Apra Harbor, Naval Base Munitions Site, Naval Hospital, Naval Base Telecommunications Site, Naval Base Barrigada, Nimitz Hill, Santa Rita Navy Complex, and Andersen Air Force Base.
The underlying technology stack is grounded in proven facility and utility operations practices rather than proprietary software or AI systems, with service delivery organized around program management, public works, and environmental compliance functions including hazardous waste management and a Navy Water Quality Laboratory. The company employs 501-1,000 personnel, with long-tenured staff and a leadership bench comprising West Point graduate and PMP Charles B. Hazzard III as President & CEO, Six Sigma-trained Shiela Concepcion as Business Director, and retired U.S. Navy Civil Engineer Corps officer Mark Lopez as Public Works Director.
Revenue is generated through a managed-services government contract model with the U.S. Navy as the primary customer, supplemented by work for the U.S. Air Force at Andersen Air Force Base and the Guam National Guard. Pricing is fixed-price/cost-reimbursable under federal procurement and is not publicly disclosed. Go-to-market is direct enterprise field sales targeting government partners, with the company positioning itself as the Navy's BOS "contractor of choice" through performance, cost control, and continual process improvement.
