Japan and Australia Deepen Defence Ties: Missile-Range Access and Joint Laser Project
8/19/2026, 2:13:40 AM
Core Event – Planned Hypersonic Missile Tests in Australia
The deal also formalised cooperation on Project Boobook, a co-developed high-energy laser system for land and littoral platforms.
Background & Context
The arrangement builds on a strategic alignment as both nations respond to a “challenging and volatile” Indo-Pacific security environment. In 2025 the countries concluded a A$10 billion (US$7.11 billion) defence export deal for Australia to acquire upgraded Mogami-class frigates. The missile-range access agreement is described as the second-most significant bilateral weapons-testing partnership after that with the United States.
Data & Statistics
- A$10 billion contract for up to 11 Mogami-class frigates, first three built by Mitsubishi Heavy Industries in Japan, the rest in Western Australia.
- AU$70 million investment by Mitsubishi Electric Australia for a new manufacturing facility in Rydalmere, Sydney, to produce the Boobook laser system.
- The laser prototype has completed field trials in South Australia; power output and platform integrations remain undisclosed.
- The missile-range agreement spans ten years and covers “a range of missile capabilities,” including hypersonic weapons.
Official Statements & Responses
Australian officials framed the partnership as providing “strategic depth” for Japan and enhancing regional deterrence. Marles said the arrangement will enable Japan to conduct test launches beyond its own limited range infrastructure. Both ministers noted the agreement complements existing collaboration on frigate procurement, joint training, and information sharing.
Verbatim Quotes
- “We have spoken previously about Australia being able to provide strategic depth to Japan across a range of areas, but one of them is the use of our ranges,” — Defence Richard Marles, Australian defence minister
- “We have agreed to progress a better and enhanced arrangement between Australia and Japan for Japan’s use of our missile ranges over the next decade across a range of missile capabilities,” — Foreign Minister Richard Marles, Australian defence minister
- “Japan and Australia have a unique close relationship built on strategic alignment and a shared vision for a safe and prosperous region.” — Shinjiro Koizumi, minister
Timeline
- April 18 – Koizumi and Marles signed the Mogami frigate memorandum aboard the JS Kumano in Melbourne.
- August 18 2026 – Announcement of missile-range access and Project Boobook progress.
- August 5 2025 – Marles slated to reaffirm Japan’s selection of the upgraded Mogami class for Australia’s next frigate program.
Why It Matters
Testing hypersonic missiles on Australian soil expands Japan’s long-range strike development, addressing its domestic range constraints. For Australia, the laser project deepens its defence industrial base and reinforces its role as a hub for allied weapons testing.
What's Next
Australian officials said discussions will refine the operational framework for missile-range use, with protocols expected within the next year. The Boobook laser system is slated for further integration trials on land-based and naval platforms, supported by the new Sydney facility.
