Japan mulls extending high-speed missile range to defend Diaoyu Islands, say sources
- Japan is considering extending the range of a new high-speed missile to defend the disputed and uninhabited islands that it calls the Senkakus
- The envisioned upgrade will come at a time when Japan is ramping up its deterrence amid North Korean nuclear, missile threats and China’s military assertiveness
Spratly Islands, Diaoyu, Bay of Bengal: is a storm brewing in Asia-Pacific waters?
The missile Japan is hoping to develop contains a number of features that will make it difficult to intercept.
After it is fired from a mobile launcher, the warhead separates at high altitude and travels on an irregular trajectory before gliding at supersonic speed toward its target.
Research on the missile began in fiscal 2018, and current prototypes have a range of several hundred kilometres. These are expected to be mass-produced from next financial year and deployed in fiscal 2026. The improved version will extend the range beyond 1,000km.
The move comes as Japan is trying to develop its own stand-off missiles – capable of attacking enemy vessels from outside their firing range – that can be launched not just from land but also from ships and aircraft.
As such, it is planning to extend the range of the Ground Self-defence Force’s Type-12 surface-to-ship guided missiles.
In addition, Japan is considering buying US-developed Tomahawk cruise missiles, which have a range of up to 2,500km and can travel relatively low to the ground, to bolster its deterrence capacity, according to government officials.
