Melbourne, April 18 (NationPress) Japan and Australia have officially announced the signing of contracts to collaboratively construct three out of the 11 ships intended for the Australian Navy. These vessels are derived from Japan's enhanced Mogami-class frigate, as reported by a Japanese news outlet.
During a press conference held in Melbourne, Japanese Defence Minister Shinjiro Koizumi and Australian Defence Minister Richard Marles, who also serves as Deputy Prime Minister, revealed the details of this agreement, according to Kyodo news.
Mitsubishi Heavy Industries Ltd., the manufacturer of the Mogami-class ships, has also entered into this contract.
Following their discussions, Marles stated in a joint press event aboard the Mogami-class Kumano frigate that the construction of these vessels will take place in Japan, with an expected delivery to Australia by December 2029.
The Australian government plans to allocate up to AU$20 billion (approximately $14.4 billion) over the next decade for the development of a new naval fleet. The upgraded Mogami-class frigates feature a 32-cell Vertical Launch System and have a range of 10,000 nautical miles.
As per the Australian government, these ships will be armed with surface-to-air and anti-ship missiles, manned by a crew of 92 Royal Australian Navy personnel, and will support operations of an MH-60R Seahawk maritime combat helicopter.
The Kyodo report highlighted that Australia’s military is currently facing a personnel shortage, making the frigate an advantageous addition due to its capability to operate with half the crew of a conventional frigate.
Australia’s Defence Ministry emphasized, “Japan is an essential partner for Australia. As Special Strategic Partners, we maintain one of the closest and most robust partnerships in the Indo-Pacific, built on mutual trust, shared values, and extensive strategic alignment developed over decades of collaboration.”
“This year marks the 50th anniversary of the Basic Treaty of Friendship and Cooperation between Australia and Japan, and our partnership continues to flourish,” Marles added.
