U.S. Pauses $14B Taiwan Arms Sale to Preserve Iran War Munitions

The Trump administration has paused a planned $14 billion arms sale to Taiwan, with the Acting Navy Secretary citing the need to preserve munitions for the ongoing Iran campaign. The pause adds fresh uncertainty to a deal that has been sitting on the President’s desk for months and could ripple through U.S. defense primes with major Taiwan exposure.

What was said

Acting Navy Secretary Hung Cao said Thursday the U.S. is pausing a $14 billion arms sale to Taiwan because of the Trump administration’s war with Iran. The remarks came during a Senate Appropriations Defense Subcommittee hearing.

“Right now we’re doing a pause in order to make sure we have the munitions we need for Epic Fury — which we have plenty,” Cao told Sen. Mitch McConnell. Cao said any decision to move forward with the sale – which would be the largest ever weapons transfer to Taiwan – would be made by Secretary of Defense Pete Hegseth and Secretary of State Marco Rubio.

Why it matters for stockpiles

The United States has reportedly burned through thousands of missiles since the Iran war began on Feb. 28, using nearly all of the long-range stealth cruise missiles left in Washington’s stockpile and depleting its stores of Tomahawks, Patriot interceptor missiles, Precision Strike and ATACMS ground-based missiles.

The White House is planning to ask Congress for a reported $80 billion to $100 billion supplemental for the war in Iran — with a significant chunk meant to backfill costly and sophisticated weapons expended in the now 12-week conflict, which since early April has settled into a tense ceasefire. That backfill is the trade angle for defense investors watching missile and interceptor producers.

The China angle

The move adds fresh uncertainty to a deal that’s been awaiting President Trump’s sign-off for months and includes PAC-3 air defense missiles and other surface-to-air systems. Trump has publicly called the package “a very good negotiating chip” with Beijing and has not committed to approving it.

Xi is reported to have issued a strong warning at the meeting with the US leader, telling him that the “Taiwan question” is the most important issue in US-China relations and that the two nations could “have clashes and even conflicts,” if the issue isn’t handled properly.

Taiwan reaction

Cao acknowledged he hasn’t spoken with Taipei, and Taiwanese officials said Friday that they hadn’t been notified about any pause in the planned arms sale.

For Taiwan, the suspension adds to an already substantial backlog of undelivered U.S. military equipment. By December 2025, outstanding U.S. defense deliveries to Taipei had exceeded $21.45 billion. Taiwanese officials had already acknowledged delays involving multiple systems scheduled for delivery in 2025, including F-16 Block 70 fighters, AGM-154C glide bombs, Patriot missile systems, and MK-48 torpedoes.

Options market and stocks to watch

Watch LMT for any flow tied to the PAC-3 and F-16 Block 70 programs, both of which are central to the stalled Taiwan package and the Iran backfill story.

Watch RTX on Patriot interceptor and Tomahawk demand, given the reported stockpile drawdown and a possible $80B–$100B supplemental ask.

Watch NOC and GD for broader munitions and shipbuilding read-throughs, plus LHX on precision-strike and electronic-warfare exposure. For other market headlines, see Unusual Whales news.
