US Weapons Depletion in Iran Conflict Threatens Near-Term Defense Plans for Taiwan

Washington, Friday, 24 April 2026.
Rapidly depleting US munitions in the Iran conflict mean replacing stockpiles could take six years, severely limiting America’s near-term ability to defend Taiwan against a potential Chinese invasion.

The Strain on US Arsenals

Since the conflict with Iran escalated on February 28, 2026, the United States has expended a staggering volume of high-end munitions [1]. According to defense officials, US forces have fired over 1,000 long-range Tomahawk missiles and between 1,500 to 2,000 critical air-defense interceptors, including THAAD, Patriot, and Standard Missiles [1][3]. This rapid drawdown has created a precarious timeline for military readiness, as completely replenishing these highly sophisticated stockpiles could take up to six years [1].

Legislative Pressures and Budget Battles

In response to these shifting geopolitical tides, pressure is mounting on Taipei to assume greater financial responsibility for its own deterrence [5]. Taiwan’s President William Lai, who has committed to increasing core defense spending to 5 percent of the island’s GDP by 2030, proposed an eight-year special defense budget of NT$1.25 trillion (approximately $39.68 billion) in late 2025 [5]. However, the proposal has stalled in Taiwan’s legislature, where the opposition Kuomintang (KMT) party holds a majority and has countered with a drastically reduced funding proposal of NT$380 billion to NT$400 billion, representing a maximum of just 32 percent of Lai’s original request [5][7].

Procurement and Joint Production Initiatives

Despite the broader budgetary disputes, Taiwan’s Ministry of Defense secured a critical victory on April 22, 2026, finalizing six weapons procurement contracts with the United States totaling $6.6 billion [2][4]. The largest of these agreements allocates $3.9 billion for M142 High Mobility Artillery Rocket Systems (HIMARS) and $2.3 billion for M109A7 Paladin self-propelled howitzers, though the extended delivery timelines mean work will not be completed until December 2032 and December 2034, respectively [2][4].

Sustaining Financial Support Amid Shifting Priorities

Financial support from Washington remains a cornerstone of Taiwan’s defense strategy, even as US lawmakers navigate competing domestic priorities [GPT]. On April 23, 2026, the US House Appropriations Committee released its fiscal 2027 funding bill for national security and the State Department, explicitly earmarking at least $500 million in Foreign Military Financing (FMF) for Taiwan [6]. The FMF program is designed to help partner nations acquire American military equipment, services, and training [6].
