A shipbuilding programme is mostly a question about capacity, and capacity is mostly a question about things that take longer than a budget cycle to change — dry docks, welders, forging capacity, a supplier two tiers down who makes one part for everybody. That is why appropriations and deliveries come apart, and why comparisons between national fleets are usually comparisons between order books rather than output. These analyses start from the yards: what is under construction, what is holding it up, and which of those bottlenecks more money can actually clear.
Yard capacity and throughput · skilled trades · order books versus deliveries · maintenance backlogs · comparative output
Final assembly for every nuclear-powered US Navy vessel runs through just two certified shipyards — Electric Boat in Groton, Connecticut and Newport News in Virginia — and no upstream fix adds a third dry dock.

Australia's entry into the US submarine steel chain so far amounts to one documented order worth roughly $2 million, turning raw plate into submarine-grade steel — a qualification step, not yet a scaled supply line.
The US Navy obligated $76.6 billion in July 2026 to the same two shipyards that have been building attack submarines below the funded two-boats-a-year rate since 2022, and there is no third certified yard.

The Navy estimated $15.1 billion for the first of its new battleships; Congress's budget office, pricing it nuclear-powered, says $23.4 billion for that one hull and $275 billion for 15 ships through 2056.
Congress's budget office warns that assembling the new battleships at Newport News would use the dock now building aircraft carriers, extending delays on three Ford-class carriers already behind schedule.
China wins this matchup on capacity it already owns — its yards took over 80% of global new ship orders in early 2026, while the US Navy's four public shipyards already miss existing destroyer and frigate schedules.

37 percent of the US attack submarine fleet reportedly cannot deploy because of maintenance backlogs, before the Navy adds a $275 billion battleship program and reclassified strike submarines to the same yards.
The $275 billion battleship program the US Navy is pursuing may not be buildable in American yards, according to independent analysis, and the allied yards that could build it are restricted by Buy America rules.
Navy shipbuilding drew more than 2 million applications to produce roughly 10,000 hires, then 50 to 60 percent of new industrial-base workers quit within their first year — the constraint is retention, not recruiting.

Ingalls Shipbuilding gave production workers an immediate 18 percent base wage increase, with total pay set to rise 35 to 47 percent through 2031 — after Navy officials blamed attrition on uncompetitive entry pay.
The widely repeated claim that submarine shipbuilding needs 140,000 more workers comes from BlueForge Alliance, a Navy-funded nonprofit whose own contract, worth up to about $980 million, pays for recruiting campaigns.
The acting head of the U.S. Navy told the Senate he needed more shipyards, not more money — only two American yards are certified to build nuclear submarines, and no third one exists to absorb extra funding.

U.S. attack submarine production is running at about 60% of its target rate despite contracted funding, and the Navy's own review found the shipbuilding industrial base needs 174,000 new workers this decade.
China has more warships than the United States, but by tonnage — a rough proxy for combat power — the U.S. lead is closer to 2-to-1 today, narrowed from roughly 3-to-1 a decade ago.
