📰 Full Story
Australia and Japan on April 18, 2026, finalised contracts launching a landmark program to supply the Royal Australian Navy with 11 upgraded Mogami-class general-purpose frigates.
Mitsubishi Heavy Industries won the competition and will build the first three ships in Japan, with the remainder scheduled to transition to domestic construction at the Henderson shipyard near Perth.
The first vessel is due for delivery in December 2029 and expected to enter service in 2030.
The vessels are described as multi-role stealth frigates equipped for anti-submarine warfare, surface strike and air defence (including a 32-cell vertical launch system) and operate with crews of about 90.
Canberra has placed the program value in public statements between A$10 billion and A$20 billion over the coming decade, with officials stressing additional spending on shipyard redevelopment and infrastructure.
The signing was framed as a deeper strategic and industrial partnership as Japan relaxes export rules; Canberra says the program will underpin Australia’s shipbuilding backbone while bolstering maritime deterrence across the Indo-Pacific.
