Navy wins $453m ADNS contract

The U.S. Navy has handed five companies places on a contract vehicle worth up to $452.9 million to keep building and updating one of its core tactical networking systems. The awards cover the Automated Digital Network System, or ADNS, a long-running Navy program used to move data across ships, shore sites and airborne routing systems. The contracting notice says the work includes production units, components, commercial software, spares and future cyber-threat upgrades. The ordering period runs through May 2034. ### Which companies actually won spots on the contract? The Pentagon’s daily contract announcements named Management Services Group, doing business as Global Technical Systems, Leidos, Serco, Systems Engineering Support Co. and VT Milcom as the five awardees. The companies are based in Virginia Beach, Reston, Herndon, San Diego and Virginia Beach, respectively. Each received an indefinite-delivery/indefinite-quantity, firm-fixed-price contract under the same vehicle. (news.clearancejobs.com) The Naval Information Warfare Systems Command, or NAVWAR, is managing the procurement. The contract numbers listed in the award notice run from N0003926D9501 through N0003926D9505. ### What is ADNS, and where does it sit in the Navy’s network stack? ADNS is a Navy program of record that adapts commercial off-the-shelf and government off-the-shelf hardware and software for tactical wide-area networking. (news.clearancejobs.com) A July 2025 statement of work described the system as supporting the acquisition, integration, delivery and sustainment of tactical network infrastructure for fleet combat-support systems under Program Executive Office C4I and PMW 160, the Navy office for tactical networks. Older Navy program descriptions say ADNS provides wide-area network gateway services for surface ships, submarines, aircraft and shore locations. The current solicitation material indicates the system is fielded in different variants across those platforms because of configuration and technical upgrades. ### What work will the contractors be competing to do? (govconwire.com) The May 21 award notice says task orders can cover ADNS production units, components, commercial off-the-shelf software, spares, lab material, cyber-threat upgrades and mission-focused upgrades. The same notice says the work is intended to support required target inventory objectives for shore and afloat platforms and airborne routing systems. (afcea.org) GovConWire, citing the Navy’s statement of work, reported that the scope also includes integrated logistics support, configuration management, quality assurance, installation support, supply-chain risk management, factory acceptance testing and cybersecurity compliance. The work is build-to-print, meaning contractors will manufacture and deploy systems using government-provided technical data packages.

The new vehicle carries an eight-year ordering period ending in May 2034, according to the award notice. The ceiling value is slightly below the prior ADNS Increment III support contract, which GovConWire said was a $492.4 million IDIQ awarded in 2017 to Leidos, Leonardo DRS, SAIC and Serco. (govconwire.com) AFCEA’s report on that earlier award said ADNS Increment III was intended to increase network capacity by taking advantage of higher-bandwidth satellite communications. That earlier history helps explain why the latest contract blends production with modernization and cyber upgrades rather than treating the system as a finished product. (news.clearancejobs.com) ### Why does a networking contract like this matter to naval operations? The Navy’s own solicitation language ties ADNS to tactical network infrastructure used across fleet combat-support systems. In practice, that makes it part of the communications layer that links platforms, routes data and keeps software-defined services running across deployed forces. (afcea.org) The next step is task-order competition among the five winners. NAVWAR will issue those orders over the life of the contract, with individual awards determining how much of the $452.9 million ceiling each company ultimately books.
