Taiwan has been awaiting approval of a U.S. weapons package that Reuters previously reported could be worth as much as $14 billion. The issue has drawn increased attention after President Donald Trump said earlier this month that he had not yet decided whether to authorize the proposed sale following talks with Chinese President Xi Jinping in Beijing.

Questions over the status of the package intensified after Acting U.S. Navy Secretary Hung Cao told a Senate Appropriations Defense Subcommittee hearing on Thursday that arms sales to Taiwan had been paused to ensure sufficient munitions were available for Operation Epic Fury, the military campaign launched by the United States and Israel against Iran in February.

A source familiar with the matter disputed that characterization, saying arms transfers to Taiwan require years of planning, review and implementation and are unrelated to the conflict with Iran.
“These sales take years to process and are unrelated to Operation Epic Fury,” the source said, adding that the U.S. military maintained adequate munitions inventories to support the administration’s strategic objectives.

The comments come as Washington seeks to balance support for Taiwan’s defense capabilities with broader management of relations with Beijing. China regards Taiwan as part of its territory and has repeatedly opposed U.S. arms sales to the island, urging Washington to halt such transfers.

The United States, while maintaining unofficial relations with Taiwan, is obligated under the Taiwan Relations Act to provide the self-governed island with the means to defend itself.

Following Trump’s meeting with Xi, U.S. officials reiterated that Washington’s policy toward Taiwan remains unchanged.

Taiwan’s government said on Friday it had not received any information indicating delays to pending U.S. arms sales.

Taipei rejects Beijing’s sovereignty claims, maintaining that only the island’s people can determine their future.

Speaking at a congressional hearing, Cao said foreign military sales to Taiwan had been put on hold while the Pentagon assessed weapons inventories needed for Operation Epic Fury, the U.S. campaign targeting Iran. He said the United States had sufficient stocks but was taking steps to ensure military requirements were fully met before resuming transfers.

“Right now we’re doing a pause in order to make sure we have the munitions we need for Epic Fury,” Cao said, adding that foreign military sales would continue once the administration determined it was appropriate.

The remarks mark the clearest public indication yet that the Iran conflict has affected the timing of U.S. weapons deliveries to Taiwan, which has sought to strengthen its defenses amid rising military pressure from China.

The U.S. State Department and the Pentagon did not immediately comment on Cao’s statement.
Taiwan’s Presidential Office pushed back against suggestions that approved sales were being altered. Presidential Office spokeswoman Karen Kuo said on Friday that Taipei had received no indication Washington intended to revise the arms package.

The reported delay centers on approximately $14 billion in weapons purchases sought by Taiwan, though U.S. officials have not detailed which systems could be affected by the pause.

The development comes as questions persist over President Donald Trump’s approach to Taiwan. While the United States formally recognizes Beijing rather than Taipei, U.S. law requires Washington to provide the self-governed island with defensive weapons.

China, which views Taiwan as part of its territory, has repeatedly opposed U.S. arms sales to the island. A Chinese Foreign Ministry spokesman said on Friday that Beijing’s opposition to such sales remained “consistent, clear and firm.”

Trump also signaled a potential shift in approach ahead of a recent visit to China, saying he would discuss Taiwan arms sales with Chinese President Xi Jinping. Previous U.S. administrations had maintained that decisions on arms transfers to Taiwan were a matter between Washington and Taipei and not subject to consultation with Beijing.

Following the trip, Trump said he had made no commitments to Xi regarding Taiwan and would decide on the proposed sales within a relatively short period.
The pause underscores the competing demands facing U.S. defense planners as Washington balances support for partners in the Indo-Pacific with military commitments stemming from the Iran conflict.

No reason was provided for the abrupt exit of Phelan, the Navy’s top civilian official, whose departure comes at a time of heightened operational activity, including a blockade of Iranian ports and actions targeting vessels linked to Tehran during a fragile ceasefire in the ongoing regional conflict.

Pentagon spokesman Sean Parnell confirmed the move in a statement, while the administration named Hung Cao, the current undersecretary and a retired Navy captain, as acting secretary. Cao, a former combat officer and political candidate in Virginia, assumes the role immediately.

Phelan’s departure adds to a series of leadership changes under Defense Secretary Pete Hegseth, who has removed several senior military figures since taking office last year. Those include Randy George, the Army’s top uniformed officer, as well as earlier dismissals of Lisa Franchetti and Jim Slife.

Charles Q. Brown Jr. was also removed from his post as chairman of the Joint Chiefs of Staff.The timing of Phelan’s exit appeared sudden. He had addressed a major Navy conference in Washington a day earlier and held meetings with lawmakers, including members of the House Armed Services Committee, to discuss shipbuilding plans and budget priorities, according to official communications.

Phelan, a private investment executive and founder of Rugger Management LLC, had limited prior government or military leadership experience before his nomination in late 2024. His background included advisory work with Spirit of America, a nonprofit supporting defense-related initiatives in Ukraine and Taiwan.

His tenure coincided with an expanded U.S. naval presence globally. The Navy currently has multiple aircraft carriers deployed or en route to the Middle East, and U.S. forces remain positioned for potential renewed operations should the ceasefire with Iran collapse.

Separately, naval assets have supported counter-narcotics operations in the Caribbean and were involved in the January capture of Venezuelan leader Nicolás Maduro.Cao, who succeeds Phelan in an acting capacity, is a Vietnam-born refugee who later graduated from the U.S. Naval Academy and served in special operations units, including deployments in Iraq, Afghanistan and Somalia.

He previously ran unsuccessful campaigns for the U.S. Senate and House of Representatives in Virginia and has publicly criticized diversity and inclusion initiatives in the military, as well as COVID-19 vaccine mandates imposed on service members.

His appointment comes as the Trump administration continues to recalibrate defense leadership and policy priorities, including a broader rollback of diversity programs across the armed forces.
