Why does defense spending matter to the economy?

The Department of Defense has requested $850 billion for fiscal year 2026, a sum larger than the entire gross domestic product of Switzerland, and that money flows directly into machine shops, shipyards, software firms, and testing ranges across the United States. When the Pentagon buys late and over budget, the costs ripple through every supplier and shrink the skilled workforce that builds both military and civilian technology. A weapons program delayed by two years leaves engineers idle, cancels orders for steel and semiconductors, and weakens the industrial base that private companies also rely upon. The same machine shops that mill parts for fighter jets also make medical equipment and power-plant turbines. The same welders who join submarine hulls also build pipelines and bridges. The defense industrial base is not a separate island. It is one of the most advanced and most fragile pieces of the national economy. When it rusts, the whole country pays.

How bad is the shipbuilding gap?

The United States Navy wants a fleet of 381 ships by 2045, but current construction rates make that target look distant. The Congressional Budget Office has warned that reaching even 350 ships would require sustained spending far above recent levels, while the Office of Naval Intelligence estimates that Chinese shipyards now produce roughly 200 times more commercial and naval tonnage each year than American yards. The Columbia-class ballistic missile submarine program alone is expected to cost about $132 billion, and delays there threaten both the nuclear deterrent and the shipyard workforce in Connecticut and Rhode Island. General Dynamics Electric Boat, which builds the Columbia class, has warned that the specialized welding and pipefitting trades needed for nuclear submarines take years to train and cannot be replaced by imports. Every lost month at the yard is a lost month for the regional economy. Newport News, Bath Iron Works, and the dozens of smaller shops that feed them all depend on a steady rhythm of contracts. That rhythm is broken.

What is the F-35 telling us?

The F-35 Lightning II program is the most expensive weapons system in American history, with the Government Accountability Office estimating total life-cycle costs above $1.7 trillion. Yet the program still struggles with engine reliability, software updates, and spare part shortages, and each grounded jet represents thousands of hours of labor at Lockheed Martin facilities in Texas and at suppliers across 45 states. When the Pentagon accepts a plane that cannot fly, it pays for metal that sits on a ramp instead of defending airspace. The problem is not only waste. It is a misallocation of engineering talent that could be building drones, missiles, and sensors that the Indo-Pacific competition actually demands. The F-35 is a case study in how a single procurement failure can tie up a generation of American manufacturing capacity. It is also a warning. If the Defense Department cannot manage a program it has run since 2001, what hope does it have for the artificial-intelligence and hypersonic weapons programs of the 2030s?

Can NATO spending ease the burden?

NATO leaders agreed at the 2024 Washington summit to move toward defense spending of at least 2.5 percent of gross domestic product, up from the old 2 percent guideline. Germany, long a laggard, reached 2 percent in 2024 and plans to push higher with a special fund for the Bundeswehr. The United States still shoulders roughly 16 percent of NATO's direct common funding, but the bigger issue is capability. European allies buy American missiles, radars, and aircraft, so higher NATO budgets can help U.S. factories run at fuller capacity and spread research costs across a larger market. That only works if American industry can deliver on time. If the Pentagon cannot fix its own procurement, no amount of allied spending will rescue the industrial base. The export market will shrink, and allies will look to South Korea, Israel, or even joint European ventures for equipment they once bought from American firms. Reputation is capital. The Pentagon is spending it.

What should Washington do now?

Congress should stop treating the defense budget as a jobs program and start treating it as a productivity program. That means fixed-price contracts for mature designs, multi-year procurement for ships and munitions, and real penalties for contractors that miss deadlines. It also means investing in the workforce through apprenticeships at shipyards and technical colleges, not just through weapons line items. The federal government spent more than $6 trillion in fiscal year 2025 and paid hundreds of billions in interest on the national debt. A defense dollar wasted is a dollar that cannot go to a border, a road, or a Social Security check. Taxpayers deserve weapons that work, not schedules that slip and budgets that balloon. The Pentagon's procurement slowdown is not a Beltway annoyance. It is a slow leak in the hull of the American economy. The longer Washington waits to patch it, the more expensive the repair becomes. And in the meantime, Beijing builds.
