Japan Bolsters Southwest Defenses with First F-35B Fighter Deployment
Table of Contents
Tokyo initiated the deployment of its inaugural squadron of U.S.-manufactured F-35B stealth fighters to Nyutabaru Air Base in Miyazaki Prefecture on Thursday, signaling a significant enhancement to its defense capabilities, especially in the strategically vital southwest island chain.
The deployment marks a pivotal moment for Japan’s Air Self-Defense Force (JASDF), as it introduces vertical takeoff and landing (VTOL) capabilities to its fleet. The F-35B fighters, acquired through a Foreign Military Sales agreement with the United States, are intended to operate from Japan’s modified Izumo-class helicopter destroyers, effectively transforming them into small aircraft carriers.
three F-35B aircraft arrived at Nyutabaru Air Base on August 7th, 2024, as confirmed by the Ministry of Defense.This initial deployment is part of a larger plan to acquire a total of 42 F-35B fighters by the early 2030s. The JASDF anticipates fielding six F-35B squadrons, enhancing its ability to respond to regional security challenges.
The southwest islands, including Okinawa Prefecture and the Senkaku/Diaoyu Islands (claimed by both Japan and China), are at the forefront of potential regional conflicts. The F-35B’s VTOL capability allows for operation from shorter runways and naval vessels,providing greater versatility in deploying air power to these remote locations. This is particularly crucial given the increasing activity of Chinese military aircraft and vessels in the East China Sea and surrounding waters.
The Izumo and kaga, both 248-meter long helicopter destroyers, have undergone extensive modifications at Yokosuka Dockyard to accommodate the F-35B. These modifications include reinforcing the flight decks to withstand the heat generated by the aircraft’s exhaust and installing specialized equipment for maintenance and operations. The first operational deployment from an izumo-class destroyer is expected in fiscal year 2025.
Japan’s decision to acquire the F-35B reflects a broader shift in its defense policy, moving away from a purely defensive posture towards a more proactive and assertive approach. This shift is driven by concerns over China’s growing military power and North korea’s continued missile and nuclear weapons programs. The F-35B is considered a key component of Japan’s strategy to maintain a credible deterrent and ensure regional stability.
Background and Context: Japan’s Evolving Defense Strategy
Japan’s post-World War II constitution, Article 9, renounces war as a means of settling international disputes. However, interpretations of this article have evolved over time, allowing for the progress of a robust Self-Defense Force (SDF). Initially focused on territorial defense, the SDF has gradually expanded its capabilities and scope of operations.
The acquisition of the F-35B represents a significant departure from Japan’s conventional reliance on U.S. military support. While the U.S.-Japan alliance remains central to Japan’s security, Tokyo is increasingly seeking to enhance its independent defense capabilities. This trend is fueled by concerns about the reliability of U.S. commitments and the changing geopolitical landscape.
Historically, Japan’s defense spending has been constrained by budgetary limitations and political sensitivities. However, in recent years, there has been a growing consensus within the government and public opinion that increased defense investment is necessary to address emerging security threats. In December 2022, Japan announced a ample increase in its defense budget, aiming to reach 2% of its GDP by 2027.
the F-35 program itself has faced challenges,including cost overruns and delays. However, the F-35B is widely regarded as the most advanced and capable VTOL fighter aircraft in the world, offering a unique combination of stealth, maneuverability, and payload capacity. Japan’s decision to invest in this platform underscores its commitment to maintaining a cutting-edge military.
