Taiwan Receives F-16 Block 70 for the First Time, 66 Aircraft Plan to Transform Air Power in the Western Pacific
Tanaka TakashiTaiwan Receives First F-16 Block 70, 66 Aircraft Plan to Transform Air Power in the Western Pacific
On October 2, F-16 Block 70 aircraft numbered 6727 and 6728 arrived at the Zhihang Air Force Base in Taitung, eastern Taiwan. These are the first two of the 66 aircraft ordered by the Taiwan Air Force in 2019. They will be deployed to the 7th Tactical Fighter Wing, which has been vacant since the retirement of the F-5E/F, marking a significant step in Taiwan's air defense modernization.
What Block 70 Supplements
The centerpiece of the new aircraft is the AN/APG-83 AESA radar. It integrates sensors similar to those used in the upgrades made to the existing approximately 140 F-16A/B aircraft from the outset. With the GE F110 engine, compatibility with conformal fuel tanks, and modern electronic warfare and data link capabilities, it signifies more than just an increase in numbers. It facilitates the incorporation of long-range detection, target information sharing, and integration with base air defense into a single system.
The Taiwan Air Force has stated that it will proceed with acceptance inspections and training, gradually building operational capability. While this is a cautious expression, the reality is that it is challenging to simultaneously prepare maintenance personnel, parts, armaments, and runway resilience alongside assembling the aircraft. Deliveries have been delayed from the initial schedule of 2023 due to factory relocations, supply chain disruptions, and further delays caused by adverse weather in September 2026.
Implications for Japan
The F-16 Block 70 is not solely an asset for the Taiwan Strait. The dispersed deployment of fighter jets at eastern Taiwan bases will be used not only to address threats directly across the strait but also to monitor aircraft and vessels approaching from the Pacific side. If the Japan Air Self-Defense Force, U.S. forces in Japan, and the Taiwan Air Force can share air situation data, a thicker alert network could be established south of the First Island Chain.
However, Japan cannot automatically consider Taiwan's F-16s as part of its allied forces. Taiwan is not a member of the same military alliance as Japan, and there are political limitations regarding rules of engagement, information sharing, and supply connections. If we separate capabilities from intentions, improvements in aircraft performance do not immediately translate to joint operational capabilities.
The Real Challenges Indicated by Delays
While the arrival of 66 aircraft is a welcome development, the delivery delays also indicate that U.S.-Taiwan defense industrial cooperation is not free from vulnerabilities in production capacity and transportation. What is needed in wartime is not merely the fact that "new aircraft have been purchased," but a system that can replenish losses, restore runways, and sustain operations over weeks. The first two aircraft mark the beginning of Taiwan's air power enhancement, while also highlighting the issues of sustained combat that Japan, the U.S., and Taiwan have yet to share.
