Japanese Navy (JMSDF) : Updates and Discussions

PLAN will be the fastest disappearing navy ever if it attacks Taiwan. Between this and Dark Eagle/CPS.

The HVGP is a new weapon scheduled to be deployed by the Japan Ground Self-Defense Force (JGSDF) starting in the fiscal year 2026. The hypersonic weapon is being developed for “island defense” roles. After being launched by a booster from a truck-mounted launcher, the warhead separates and glides to attack its target. The estimated range is approximately 900 km.
To achieve early deployment, the HVGP is planned to be developed in incremental capability enhancements. The test conducted this time was for the most basic “Early Deployment Version (Block 1)” test projectile. Furthermore, the development of an “Enhanced Capability Version (Block 2A)” with a significantly extended range capable of attacking targets up to 2,000 km away, and an “Enhanced Capability Version (Block 2B)” with a range of 3,000 km, is scheduled to be completed in the fiscal years 2027 and 2030, respectively.
As previously reported by Naval News, Japan’s HVGP (速滑空弾) could eventually have an anti-ship capability and be used against aircraft carriers. This consideration is part of the research on future enhanced capability versions. In the future, it is possible that the warhead could be equipped with a seeker for use in anti-ship mission.

Wright noted, “Japan is developing the HVGP for both anti-ship and land attack missions to intercept and eliminate invading forces against Japan at a distance and at an early stage.”
