Japan Unveils Hyper Velocity Gliding Projectile

Japan has recently unveiled its new ballistic missile, the "Hyper Velocity Gliding Projectile" (HVGP), marking a significant advancement in its defense capabilities. This development is part of Japan's broader strategy to enhance its standoff defense systems amid regional security challenges.

Development and Testing

The HVGP project was officially included in Japan's defense budget in the 2018 fiscal year. The missile is designed primarily for the defense of remote islands, addressing potential threats in the region. The development plan comprises two versions: the "Block 1" and the "Block 2."

  • Block 1: This early deployment model has an estimated range of approximately 300 to 500 kilometers. Development is slated for completion by fiscal year 2025, with deployment expected to commence in fiscal year 2026.

  • Block 2: A more advanced version, the Block 2 aims to extend the missile's range to about 3,000 kilometers. Deployment for this version is projected for the 2030s.

To gather essential data for the HVGP's development, Japan's Acquisition, Technology, and Logistics Agency (ATLA) conducted a series of flight tests in California. These tests, carried out between August 2024 and January 2025, were successful and provided valuable insights for the missile's progression.

Strategic Implications

The HVGP is a cornerstone of Japan's strategy to bolster its standoff defense capabilities, particularly concerning its southwestern islands. The missile's deployment is expected to enhance deterrence and provide a rapid response option against potential aggressors.

The planned deployment locations for the HVGP include Hokkaido and Kyushu, positioning the missile to cover a broad area and address various potential threats.

Regional Context

Japan's development of the HVGP occurs amid increasing regional tensions, notably due to China's military activities and North Korea's missile programs. The HVGP is designed to counteract these challenges, providing Japan with a credible deterrent and reinforcing its defense posture.

In addition to the HVGP, Japan is also advancing other missile systems, such as the upgraded Type-12 anti-ship missile. These efforts collectively aim to enhance Japan's ability to defend its territorial integrity and maintain regional stability.

The unveiling of the HVGP signifies a pivotal step in Japan's defense strategy, reflecting its commitment to enhancing its military capabilities in response to evolving regional security dynamics. As development progresses, the HVGP is poised to play a crucial role in safeguarding Japan's national interests and contributing to regional peace and stability.
