The Pentagon is putting fresh pressure on America’s defence industry to dramatically accelerate weapons production, as the continuing war with Iran consumes large quantities of some of the United States’ most important munitions.

A Defense Department memo obtained by The Washington Post shows Deputy Defense Secretary Steve Feinberg directing industry leaders to develop significantly faster production and delivery schedules for critical military capabilities. Companies were reportedly given no more than 21 days to submit their proposals.

The message from Washington is increasingly clear: the United States wants its defence-industrial base operating much faster than the traditional procurement system has allowed.

“Years-long development cycles are not acceptable,” Feinberg wrote in the memo, according to The Washington Post, calling for schedules and production capacity to be accelerated.

Why the Pentagon is moving now

The urgency comes amid mounting concern over the rate at which the United States has consumed sophisticated missiles during the Iran conflict.

The Washington Post reports that during the first month of the war alone, the United States fired more than 850 Tomahawk cruise missiles, more than 1,000 Patriot and THAAD air-defence interceptors, and more than 1,300 Army tactical ballistic missiles in the opening weeks of fighting.

Those numbers matter because many advanced missiles are complex, expensive and slow to manufacture. Unlike ammunition that can simply be replaced in huge volumes relatively quickly, modern interceptors depend on sophisticated electronics, propulsion systems, sensors and specialised manufacturing lines.

The result is a major challenge: weapons can sometimes be fired much faster than factories can replace them.

According to figures cited by The Washington Post from an analysis by the Center for Strategic and International Studies, the global inventory of Patriot missiles had fallen from around 2,200 before the war to fewer than 827, while THAAD interceptor stocks reportedly fell from 452 to fewer than 278.

Those figures illustrate why the Pentagon is now treating production capacity as a strategic issue rather than simply a procurement problem.

Pentagon wants factories expanded

The new directive reportedly goes beyond simply asking defence contractors to work faster.

Companies have also been asked to identify potential capital investments, factory expansions and other measures that would allow the industry to sustain much larger orders over time. The Pentagon wants manufacturers to present the fastest realistic schedules for delivering projected weapons orders while simultaneously increasing production capacity.

Several major American defence companies are already involved in efforts to expand missile production.

The Pentagon recently announced framework arrangements involving Lockheed Martin and Northrop Grumman aimed at increasing production of Patriot PAC-3 and THAAD interceptors. Lockheed Martin has also received a contract worth up to $58.6 billion connected with plans to triple PAC-3 production by 2030, according to The Washington Post.

The Pentagon has also been working with newer defence technology companies as it searches for ways to manufacture lower-cost missiles and other weapons at much greater scale.

Money remains a major obstacle

Producing more weapons is not simply a matter of telling factories to increase output.

Defence companies need long-term contracts before committing billions of dollars to new facilities, equipment, workers and supply chains. Some of the Pentagon’s announced arrangements remain dependent on Congress approving additional defence funding.

The Washington Post reports that a $1.15 trillion defence spending bill remains caught in congressional disagreement, complicating efforts to convert some Pentagon framework agreements into firm purchases.

That creates a difficult situation for defence manufacturers. Companies may be asked to expand production immediately, but major investments carry financial risk if promised government orders are delayed or never fully funded.

A broader strategic concern

The issue extends beyond the Iran battlefield.

The United States maintains military commitments across Europe, the Middle East and the Indo-Pacific, meaning Washington must maintain sufficient weapons not only for current fighting but also for other possible crises.

Every interceptor fired today must eventually be replaced if the United States wants to preserve sufficient reserves for tomorrow.

That is especially significant for missile defence. Patriot and THAAD systems are designed to defend military bases, troops and strategic locations against incoming ballistic missiles. If inventories fall too far, military commanders could face harder decisions about where limited interceptors are deployed and which threats receive priority.

The Pentagon therefore appears to be confronting a problem that has been building for years: America’s defence industry was largely structured around predictable peacetime production schedules, while modern conflicts can consume advanced weapons at an extraordinary rate.

Can American industry keep up?

The Pentagon’s latest demand amounts to a test of whether the world’s largest military can transform its industrial base quickly enough for a prolonged high-intensity conflict.

The United States possesses enormous technological and manufacturing capability, but expanding advanced missile production cannot happen overnight.

New factories have to be built. Supply chains have to expand. Skilled workers must be recruited. Specialised components must be manufactured, tested and certified.

And while those production lines are being expanded, the war continues consuming weapons already sitting in American inventories.

The Pentagon is now telling industry that the traditional timetable is no longer sufficient.

The question is whether America’s factories can respond quickly enough.

If the Iran war continues for months longer, can the United States rebuild its weapons stockpiles as fast as it is using them?
