Taiwan Receives First Two F-16V Block 70 Jets From US Amid Deepening Concerns Over Washington's Defence Commitment

Taiwan's air force has taken delivery of two new F-16V Block 70 fighter jets from the United States, marking a significant milestone in an $8bn arms package approved during President Donald Trump's first term. The aircraft landed at Chihhang Air Base in Taitung at noon local time on Friday, following a ferry flight that routed through Hawaii and Guam. Manufactured by US defence contractor Lockheed Martin, the jets represent the first instalment of a 66-aircraft order intended to modernise Taiwan's ageing combat fleet and bolster its ability to deter a feared military attack from China.

The delivery had been delayed for months, according to officials, largely because Beijing repeatedly pressed Washington to halt weapons sales to the self-governed island. China regards Taiwan as its own territory and has never renounced the use of force to bring it under its control. The arrival of the fighters therefore carries symbolic as well as military weight, signalling that the US remains willing to proceed with the deal despite diplomatic pressure from Beijing.

The timing is notable. The jets touched down just one week after Trump met Chinese President Xi Jinping in Washington, a summit that had raised questions in Taipei about whether the US might soften its longstanding support for Taiwan's self-defence in exchange for progress on trade or other bilateral issues. Trump said in May, following an earlier meeting with Xi in Beijing, that he was holding back a new $14bn arms package for Taiwan, though he did approve a separate $11bn package in December 2025. Those contradictory signals have fuelled anxiety in Taipei about the reliability of US commitments.

Taiwanese Minister of National Defence Wellington Koo confirmed the arrival and indicated that more aircraft would follow before the end of the year. "Of course we won't only have delivered these two by the end of the year," Koo said, suggesting that the pace of deliveries could accelerate. His remarks were aimed at reassuring the public and the military that the broader procurement programme remains on track despite the earlier holdups.

The F-16V Block 70 is an advanced variant of the venerable F-16 platform. The jets received a major upgrade in 2023 that includes modern avionics, improved radar systems and the ability to carry a wider range of precision weapons. These enhancements are designed to help Taiwan's pilots better counter the Chinese air force, including its J-20 stealth fighters, which represent a growing challenge to the island's air defences. While the F-16V is not a stealth aircraft itself, its upgraded sensors and electronic warfare suites give it a fighting chance in contested airspace.

However, Washington has drawn a clear line at supplying Taiwan with its most advanced fighter aircraft. The US has consistently refused to sell the F-22 Raptor or the F-35 Lightning II, both of which are stealth platforms that would represent a far greater leap in capability. The decision to withhold those aircraft reflects a long-standing policy of providing Taiwan with sufficient defensive tools to resist an invasion without crossing Beijing's stated red lines or triggering a major escalation.

The United States is bound by law, specifically the Taiwan Relations Act, to provide the island with the means to defend itself. Yet the two countries have no formal diplomatic relations, a legacy of Washington's decision to recognise the People's Republic of China in 1979. This awkward arrangement means that arms sales are conducted with a degree of ambiguity, often framed as commercial transactions rather than overt military alliances. The State Department reiterated that position when asked about the delivery. "We continue standing with friends and allies across the Indo-Pacific to advance our shared prosperity, security, and values — that includes Taiwan," a spokesperson said, insisting there had been no change in policy.

Taipei's concerns about Washington's commitment are not new, but they have intensified in recent years. Taiwan's government has watched as the US has pursued a series of high-level diplomatic engagements with Beijing, including the Trump-Xi summits, and has worried that Taiwan could become a bargaining chip in broader great-power negotiations. The approval of the $11bn package in December 2025 offered some reassurance, but the delayed delivery of the F-16Vs and Trump's public hesitation over the $14bn package have kept those anxieties alive.

Military analysts note that the F-16V delivery, while welcome, does not fundamentally alter the balance of power across the Taiwan Strait. China's air force operates thousands of combat aircraft, including increasingly sophisticated domestically produced models, and Beijing has stepped up military drills around Taiwan in recent months. The two jets delivered on Friday are a fraction of the 66 promised, and even a full complement would not close the numerical gap. Instead, they are intended to raise the cost of any invasion and to signal that the US remains engaged.

For Taiwan's pilots, the new jets offer a tangible upgrade. The Block 70 variant features an active electronically scanned array radar, which allows for longer-range detection and tracking of multiple targets. It also incorporates a modern cockpit with large displays and helmet-mounted cueing systems, improving situational awareness in close combat. These features are particularly important given the threat posed by China's J-20, which is designed to penetrate contested airspace and strike high-value targets.

The delivery also carries industrial and political significance for Lockheed Martin and the US defence industry. The $8bn deal supports jobs in the United States and reinforces the broader defence relationship between Washington and Taipei. It comes as Taiwan has passed a defence budget after a record delay, retaining funding for drone programmes and other asymmetric capabilities. That budget reflects a strategic shift toward smaller, cheaper weapons that can be deployed in large numbers to complicate a Chinese invasion.

Still, the overarching question remains whether the US will continue to arm Taiwan at a pace that matches the threat. Beijing's repeated requests for Washington to stop arming the island have not gone unanswered, and Trump's own comments have introduced uncertainty. The arrival of the two F-16Vs is a positive step for Taipei, but it is unlikely to fully dispel the doubts that have taken root in the island's capital about the durability of American support.
