The Pentagon’s Trillion-Dollar Paradox

Months before American missile stocks became a political controversy, Defense Secretary Pete Hegseth stood before an audience in Washington and offered an unusually severe diagnosis of the system responsible for building America’s weapons.

The Pentagon, he argued, had become dependent on a defense industry characterized by limited competition, vendor lock, cost-plus contracts, unstable budgets and slow procurement. Companies had learned to operate like the bureaucracy they served: cautiously, slowly and with little incentive to expand production before government money was guaranteed.

His alternative could be summarized in two words; speed and volume. The Pentagon would give manufacturers larger and longer contracts, accept weapons that met 85 percent of requirements rather than waiting years for theoretically perfect systems, encourage multiple suppliers and demand that major contractors invest their own capital in expanded factories.

“Unstable demand signals,” Hegseth said, had helped produce an industry that was risk-averse and lethargic. The Pentagon needed companies capable of scaling production in a crisis.

At the time, this sounded like another Pentagon acquisition reform initiative. But months of high-intensity warfare with Iran have consumed substantial portions of American inventories of Patriot and THAAD interceptors, Tomahawk cruise missiles, JASSMs and Army long-range missiles. Some systems will require years to return to their previous stockpile levels.

The resulting question is how can a country requesting $961.6 billion for its Defense Department in 2026 find itself short of missiles? The answer lies partly in decisions made more than three decades ago.

The Last Supper

America once organized its defense economy around almost the opposite principle. During World War II, spare capacity was not regarded primarily as an inefficiency. Industrial mobilization itself was a weapon.

After Pearl Harbor, the Army’s Rock Island Arsenal moved to production 24 hours a day, seven days a week. Workers sometimes ate sandwiches beside their machines rather than stopping production. Employment there eventually reached 18,675, with women comprising 68 percent of the workforce by the end of the war.

That was the material basis of Franklin Roosevelt’s famous description of America as the “arsenal of democracy”: a civilian industrial economy capable of being transformed into enormous wartime productive capacity.

Half a century later, American policymakers faced the opposite problem. The Soviet Union had disappeared. Defense budgets were falling. Hundreds of factories and dozens of competing military contractors suddenly looked excessive.

On July 21, 1993, Defense Secretary Les Aspin and his deputy William Perry invited executives from the country’s leading defense companies to dinner at the Pentagon. The evening became legendary in the defense industry as “the Last Supper.”

Perry displayed a chart showing executives that the Pentagon could no longer afford all of them. There were too many companies chasing too few aircraft, missiles, satellites and armored-vehicle contracts. Washington effectively encouraged them to consolidate.

Over the following years, companies merged with extraordinary speed. Lockheed combined with Martin Marietta. Boeing absorbed McDonnell Douglas. Northrop acquired Grumman. Raytheon became increasingly dominant in missiles.

The Pentagon later calculated that the number of major aerospace and defense prime contractors fell from 51 to five: Lockheed Martin, RTX, General Dymanics, Boeing and Northrop Grumman. Today, roughly 90 percent of American missiles come from only three sources.

Commercial defense-industrial output fell by roughly 35 percent during the 1990s, while government facilities were closed or reduced. At the time, this was not necessarily irrational. Maintaining several factories capable of producing the same weapon was expensive, while empty production lines require buildings, machinery and specialized workers even when nothing is being ordered. America consequently exchanged redundancy for efficiency.

The wars America expected

Iraq and Afghanistan reinforced a particular model of American warfare. The United States, possessing overwhelming air superiority and precision weapons, managed to destroy important targets efficiently. Adversaries would have limited capacity to threaten American bases.

America therefore needed extraordinarily capable weapons, but not necessarily enormous quantities of every weapon. Factories produced missiles at relatively low, predictable peacetime rates. Inventories could be replenished gradually. Capacity sitting unused in anticipation of an unlikely great-power war looked financially wasteful.

Meanwhile, Pentagon money increasingly flowed toward expensive platforms, research and technology. The 2026 Pentagon request illustrates the distinction. Of $961.6 billion requested for the Defense Department, about $153 billion belonged to the base procurement account. Hundreds of billions instead finance personnel, operations, maintenance, R&D and other responsibilities.

Even within procurement, ammunition must compete with submarines, aircraft, satellites and vehicles. A fighter aircraft is politically attractive. It operates for decades, generates jobs across congressional districts and visibly demonstrates American power.

The Ukrainian alarm

Within weeks of Russia’s invasion of Ukraine, the United States had transferred so many Javelin anti-tank missiles that analysts estimated roughly one-third of the American inventory might already have been sent abroad.

At the production rate then in place, Javelin replacement would take years. Even reaching the manufacturer’s theoretical maximum production rate required additional time. New missiles had delivery lead times measured in years rather than months.

The Stinger surface-to-air missile provided an even more striking anecdote. America had stopped buying significant numbers of new Stingers around two decades earlier. When Ukraine suddenly needed thousands of them, Washington discovered that a weapon could remain operational in the military inventory even though the industrial ecosystem needed to manufacture it at scale had largely disappeared.

This is where the shortage becomes a technical problem rather than merely a budgetary one. A Patriot interceptor contains rocket motors, guidance electronics, seekers, specialized explosives, batteries, actuators, semiconductors and precision-manufactured components sourced through a complicated network of subcontractors.

The production line can move only as quickly as its slowest indispensable supplier. Solid rocket motors are among the clearest bottlenecks. Decades of consolidation left only a small number of major American manufacturers. Similar shortages exist throughout the supply chain.

For one missile program examined by the Government Accountability Office, lead times for electronic components increased from 19 months to 34 months.

The wrong incentives

Hegseth’s criticism of contracting addresses another part of the puzzle. Defense manufacturers have historically had little incentive to maintain substantial unused production capacity. Expanding missile output requires large upfront investments in factories, specialized machinery, skilled labor and supplier networks, while Pentagon demand can fluctuate sharply from one budget cycle to another.

Without long-term procurement commitments, companies risk investing heavily to meet a temporary wartime surge only to find themselves operating oversized production lines once demand subsides. This uncertainty has encouraged an industrial model built around relatively predictable peacetime orders rather than the spare capacity required for rapid wartime expansion.

This is why Hegseth has placed such emphasis on multiyear procurement agreements. By committing the Pentagon to sustained purchases over several years, the government gives defense manufacturers the predictable demand they need to justify investments in new factories, additional production lines and larger supplier networks. The objective is to replace short-term emergency orders with a more stable industrial policy capable of expanding output before the next crisis.

The most troubling lesson, however, concerns consumption itself. Modern high-intensity warfare burns ammunition at rates that peacetime procurement systems were never designed to match. Iran can launch relatively inexpensive drones and ballistic missiles. The United States may respond with Patriot, THAAD or sophisticated naval interceptors costing millions of dollars each and requiring years to manufacture in quantity.

America can therefore win the tactical exchange, destroying the incoming missile, while losing the industrial exchange. The Iran war has exposed this contradiction more dramatically than Ukraine because the United States is consuming many of these weapons itself rather than transferring them to another military.

Hegseth’s criticism therefore reaches beyond Pentagon bureaucracy. The United States has constructed an entire defense economy around assumptions inherited from the post-Cold War era such as relatively short wars. That model produced extraordinarily sophisticated weapons.
