The Navy has awarded DZSP 21 LLC a $138,004,329 cost-plus-award-fee modification to keep base operations running across Joint Region Marianas in Guam, pushing the contract's cumulative face value to $908,108,425.
Background
DZSP 21 LLC, headquartered in Chantilly, Virginia, holds the base operations support services contract for Joint Region Marianas, the joint command that oversees Navy, Marine Corps, and Air Force installations on Guam. The contract, numbered N40192-25-C-5400, is managed by Naval Facilities Engineering Systems Command Marianas and covers the day-to-day work that keeps the island's military installations functioning: facilities maintenance, utilities, grounds keeping, custodial services, and other recurring base support functions.
The July 29, 2026 award exercises Option Period Six of the underlying contract. Guam's installations have expanded steadily as the Department of War shifts more force posture toward the Indo-Pacific, and DZSP 21's base support work has grown alongside that buildup. A year earlier, in July 2025, the Navy exercised Option Period Five on the same contract with a $116 million modification that brought the cumulative value to $849 million at the time. The new $138 million action continues that pattern of annual option exercises, each adding tens of millions of dollars to the contract's cumulative face value as Guam's basing mission expands.
Joint Region Marianas sits at the center of the Pentagon's Pacific posture, encompassing Navy, Marine Corps, and Air Force installations across Guam. Base operations contracts like this one are the connective tissue that keeps those installations livable and mission-ready as the Pentagon's Indo-Pacific force posture continues to grow.
DZSP 21 has held the incumbent role on this contract across multiple option periods, giving the company a long operating history on Guam and deep familiarity with the logistical challenges of sustaining installations on an island roughly 6,000 miles from the continental United States. That incumbency matters in a market where shipping delays, limited local labor pools, and typhoon-driven facility damage can complicate base operations work in ways that mainland contracts rarely encounter. The company's continued selection for Option Period Six, rather than a shift to a new provider, suggests the Navy has been satisfied with performance under the prior five option periods.
Key Details
The modification is structured as a cost-plus-award-fee action, meaning DZSP 21 is reimbursed for allowable costs plus a fee tied to performance evaluations rather than a fixed lump sum. That structure is typical for recurring base operations support work, where scope can shift month to month based on installation needs.
Of the $138,004,329 total award value, the Navy obligated $32,726,022 at time of award, drawn from fiscal year 2026 operations and maintenance funds spread across the Navy, Marine Corps, and Defense accounts. Those funds expire at the end of the current fiscal year, which is standard practice for O&M dollars that must be obligated and executed within the year they are appropriated, even when the underlying option period extends further into the future.
The modification carries an estimated completion date of July 2027, consistent with a roughly one-year option period. Naval Facilities Engineering Systems Command Marianas, based in Guam, is the contracting activity responsible for administering the award. The Department of War listed the action in its official "Contracts for July 29, 2026" release, which also included the contract number N40192-25-C-5400 tying the modification to the base award.
The year-over-year comparison illustrates the trajectory of the contract's growth. The July 2025 Option Five modification was valued at $116 million and brought the cumulative face value to $849 million. One year later, Option Six adds $138 million and pushes the total past $908 million. That roughly $22 million increase in the size of a single annual option, from $116 million to $138 million, tracks with the broader expansion of Guam's basing infrastructure as military construction and other Indo-Pacific initiatives continue to add facilities that require ongoing operations support.
The contract's cumulative growth trajectory now spans multiple years of option exercises, each adding a nine-figure sum to the total. At $908,108,425 cumulative face value, the DZSP 21 award ranks among the larger recurring base operations contracts in the Pacific theater, and it illustrates how quickly base support spending can scale on an installation experiencing sustained force posture growth. The contract number, N40192-25-C-5400, ties this modification directly to the base award record maintained by Naval Facilities Engineering Systems Command Marianas.
What It Means for Contractors
The DZSP 21 award is a reminder that base operations support contracts, while less visible than major weapons programs, represent some of the largest and most durable revenue streams in the government contracting market. A single contract now approaching $1 billion in cumulative value demonstrates how option-year structures compound over time, particularly at installations undergoing active growth.
For companies competing in the base operations support space, Guam remains one of the most active markets in the Indo-Pacific theater. The steady annual option exercises on this contract, each larger than the last, signal that Naval Facilities Engineering Systems Command Marianas expects the scope of work at Joint Region Marianas to keep expanding rather than plateau. Firms holding or pursuing similar base operations, facilities maintenance, or logistics support contracts in the Pacific should expect continued demand growth tied to evolving force posture and the military construction pipeline feeding new facilities that will eventually need their own operations and maintenance coverage.
The award also underscores a practical funding dynamic worth tracking: even multi-year option contracts are funded incrementally with annual O&M dollars that expire at fiscal year-end. Subcontractors and teaming partners working under prime base operations contracts should watch for the same pattern of partial obligation followed by incremental funding actions throughout the option period, rather than assuming the full modification value is available for invoicing immediately.
Finally, the contract's growth curve offers a useful benchmarking data point for any firm pricing recompetes or follow-on proposals for Guam-based support work. An increase from $116 million to $138 million across one option year is a meaningful signal of cost growth in the market, whether driven by labor rates, material costs, or expanded scope, and should factor into cost estimates for firms preparing bids on comparable Pacific basing support requirements in the near term.
