Naval Information Warfare Systems Command has awarded a $452.9 million multiple-award indefinite-delivery, indefinite-quantity contract to five companies for production, spare parts, software, and upgrades to the Automated Digital Network System — the backbone communications network linking Navy surface ships, submarines, aircraft, and shore sites into a single tactical wide-area network. The awardees are Leidos, Serco, Systems Engineering Support Co., Management Services Group (doing business as Global Technical Systems), and VT Milcom, a subsidiary of VT Group Holdings.
The ADNS program is not a household name in defense contracting circles, but it quietly underpins nearly every Navy tactical communications exchange at sea. The system allows warships, submarines, patrol aircraft, and land-based command nodes to share data across the same wide-area network during operations. Without ADNS functioning reliably, the Navy's ability to coordinate distributed maritime operations would degrade significantly. The new IDIQ contract covers the full lifecycle of keeping that infrastructure healthy — from manufacturing new build-to-print units to sustaining existing hardware in the field.
What the Contract Covers
Under the new agreement, the five contractors will compete for individual task orders across a range of services. Those services include production of new ADNS units, integrated logistics support, configuration management, quality assurance, installation support, supply chain risk management, factory acceptance testing, and cybersecurity compliance activities. The combination of production and sustainment work under a single IDIQ vehicle gives the Navy flexibility to ramp up either capability depending on fleet demands without renegotiating separate contracts.
Work will be performed primarily in California and Virginia, the two states where Naval Information Warfare Systems Command maintains its major operations. The ordering period runs eight years, through May 2034, giving all five contractors a long runway for task order competition. The $452.9 million figure represents the ceiling across the entire vehicle — individual task order values will determine what each company actually earns.
This award follows a prior ADNS Increment III support contract worth approximately $492 million that was issued in 2017 to Leidos, Leonardo DRS, SAIC, and Serco. Two of those firms — Leidos and Serco — have now secured spots on the follow-on vehicle as well, reflecting their demonstrated experience with the program. The addition of Systems Engineering Support Co., Global Technical Systems, and VT Milcom broadens the competitive pool and introduces new entrants who can challenge for individual task orders.
What It Means for Contractors
For the three smaller awardees — Systems Engineering Support Co., Global Technical Systems, and VT Milcom — landing a spot on this IDIQ is a significant win that opens the door to Navy tactical communications work for nearly a decade. IDIQ vehicles of this type function as long-term licenses to compete: the hard part is winning a place on the contract, and these firms have done exactly that. The challenge now shifts to building the program relationships and proposal capabilities needed to win individual task orders against established competitors like Leidos and Serco.
Firms that were not selected should note the structure of the prior 2017 vehicle and this new award. The Navy has consistently favored a multi-awardee approach for ADNS support, spreading work across several companies rather than consolidating it with a single prime. That pattern suggests the agency values competitive pressure on task order pricing. Contractors interested in future ADNS opportunities should track Naval Information Warfare Systems Command solicitations closely, as task orders under this ceiling can flow for eight years.
Cybersecurity compliance was specifically called out as an area of required work, which reflects the broader Defense Department push to harden tactical communications systems against adversary intrusion. Contractors pursuing task orders under this vehicle should expect robust cybersecurity requirements in each statement of work, including supply chain risk management provisions that may require vetting of component sources. Firms with established CMMC and SCRM programs will be better positioned than those still building those capabilities.
For larger primes like Leidos and Serco, the new contract preserves their established positions while opening competition to newer entrants. Both firms will need to price task orders competitively to defend market share they held under the previous vehicle. The introduction of VT Milcom, a company with deep roots in military communications hardware, adds a technically credible competitor that primes should not underestimate on production-focused task orders.
