Six major US defence contractors have agreed to sharply increase production of advanced weapons following a meeting with US President Donald Trump, as tensions escalate during the ongoing conflict with Iran.

In a post on Truth Social, Trump said the companies had committed to quadrupling production of what he described as “exquisite class weaponry” in order to rapidly boost US military stockpiles.

“We just concluded a very good meeting with the largest U.S. defense manufacturing companies where we discussed production and production schedules. They have agreed to quadruple production of the ‘exquisite class’ weaponry so we can reach the highest levels of quantity as quickly as possible,” Trump wrote.

He added that expansion of production capacity had already begun months earlier, with new plants and manufacturing lines already under development.

“We have a virtually unlimited supply of medium and upper-medium grade munitions, which we are using, for example, in Iran and recently used in Venezuela. Regardless, however, we have also increased orders at these levels,” Trump said.

Major defence firms attend White House meeting

The meeting included chief executives from some of the largest US defence contractors, including BAE Systems, Boeing, Honeywell Aerospace, L3Harris Missile Solutions, Lockheed Martin, Northrop Grumman and RTX Corporation.

Trump said states across the US are already competing to host new production facilities as the defence industry prepares for expanded manufacturing.

A follow-up meeting between the White House and industry leaders is expected to take place in two months.

Questions over new agreements

It was not immediately clear whether the meeting resulted in any new contracts beyond production increases already announced earlier by the Pentagon.

Earlier this year, the US Department of Defense signed multiyear agreements with several companies to boost the production of key missile systems. Lockheed Martin agreed to significantly increase output of PAC-3 missiles and THAAD interceptors, while RTX Corporation secured deals to expand production of weapons such as the Tomahawk cruise missile, AIM-120 AMRAAM and Standard Missile systems.

The Pentagon has also announced plans to invest $1 billion into a spinoff of L3Harris’s missile solutions business, which manufactures solid rocket motors and other key components used in advanced munitions.

Push to replenish weapons stockpiles

The discussions come during the first week of US military strikes against Iran, which have raised concerns about the pace at which American munitions are being used in the conflict.

US officials have been under pressure to accelerate weapons production after multiple global conflicts — including the war in Ukraine and fighting in the Middle East — depleted portions of US military stockpiles.

Trump has repeatedly insisted that US stockpiles remain sufficient but said production must increase to ensure the military maintains overwhelming capacity during prolonged conflicts.

Analysts say the decision signals a broader push by Washington to rapidly expand defence manufacturing as geopolitical tensions rise worldwide.
