Secretary of the Navy John Phelan announced on December 9, 2025 a $448 million strategic investment in a Shipbuilding Operating System, known as Ship OS, intended to accelerate the construction of Navy ships, according to the Navy's December 9, 2025 announcement. The initiative applies artificial intelligence and autonomy software to production scheduling, supply chains, and yard floor operations across the shipbuilding industrial base. Phelan said in the announcement that the investment "provides the resources our shipbuilders, shipyards, and suppliers need to modernize their operations" and that adopting AI and autonomy tools at scale would help the industry "improve schedules, increase capacity, and reduce costs."
What is Ship OS meant to do?
Ship OS is a software platform designed to connect data across shipbuilders, yards, and suppliers so that production bottlenecks become visible in near real time. The Navy's announcement described goals of improving production schedules, increasing shipbuilding capacity, and reducing costs, the three shortfalls most often cited in Navy assessments of delayed deliveries. American shipyards have struggled for years with late parts, out-of-sequence work, and workforce shortfalls, and department leaders have argued that digital tooling can compress schedules without new facilities. The announcement positioned the investment as an industrial-base measure rather than a weapons program, directing money at how ships get built rather than what gets built.

Why the Navy is buying software before hulls
The December 2025 announcement followed a year of department statements on delayed submarine and frigate deliveries and on the administration's push to expand the fleet through reconciliation funding. Phelan, confirmed as Secretary of the Navy in 2025, made shipbuilding throughput a signature theme of his tenure, arguing in public remarks and congressional testimony that capacity, not design, was the binding constraint. The $448 million figure puts the initiative in the range of the department's shipyard-infrastructure line items rather than its acquisition accounts, and the Navy did not publish a per-yard breakdown in the announcement. Press reporting on the initiative identified commercial AI software as the underlying technology, though the Navy's own release did not name vendors.
How the investment fits the wider shipbuilding push
The initiative lands alongside larger streams of money moving to the industrial base: the fiscal year 2026 reconciliation law added roughly $26.5 billion for ship construction, and separate workforce and facility investments are underway at the four public shipyards and at private builders. Software does not build hulls on its own, and the announcement's goals depend on yards adopting the tools across their supply chains. The Navy's release described adoption as an industry-wide effort, with suppliers as well as prime contractors in scope. Watchers of the program will track whether schedule metrics the department reports for lead ships and follow-on hulls improve over the next several budget cycles.
What to watch next
The department had not announced milestone dates, contractor selections, or per-yard deployment schedules for Ship OS as of early 2026. Implementation detail is expected to surface in future budget justification documents and in testimony before the Senate and House armed services committees during the fiscal 2027 budget cycle.
