The MOD has also requested unpriced funding for the development of a new hypersonic underwater launched missile and funding for an ongoing separate program to acquire a long range submarine-launched missile developed by Mitsubishi Heavy Industry. Research on an underwater vertical launch system, which has been ongoing, continues to be funded. Additionally, there are funding requests for ongoing long range strike missiles acquisitions such as the Joint Strike Missile (JSM), Joint Air-to-Surface Stand-Off Missile (JASSM) and the Improved Type 12 missile (air, sea and ground launched). https://news.usni.org/2026/09/01/japan-budget-requests-record-55-6b-for-unmanned-long-range-strike-capabilities
