SYDNEY — One of the biggest stories of the year in the Indo-Pacific was Japan casting aside the cloak of pacifism and moving to boost defense spending and actually export a major weapons system.

While some of the policy planks had been laid down over the least decade, this was the year Japan really began taking concrete steps to make these a reality. The importance of the development is reflected below in this selection of five stories from Asia in 2024, plus an eyebrow-raising shakeup in the Chinese military, as well as a couple reports that look at some important moves Australia made as well.

[This article is one of many in a series in which Breaking Defense reporters look back on the most significant (and entertaining) news stories of 2024 and look forward to what 2025 may hold.]

1. Japanese MoD makes first appearance at foreign airshow, seeking arms exports

When Breaking Defense saw the Ministry of Defense booth at the Singapore Air Show in February, the first reaction was shock : a Japanese government booth trying to sell weapons.

True, it was relatively small and the companies were too, for the most part. But there were Japanese officials, some in uniform, actively courting the international press, companies ands representative of foreign governments. And they spoke with Breaking Defense and encouraged the coma[pnies to speak with media.

2. ‘Huge implications’ as top Chinese military leader under investigation, joins 3rd defense minister

While Japan was trying to do one of the things China most fears — become a serious, power-projecting regional power — China’s top leadership appeared to go a bit bonkers. A senior member of the body that rules the Peoples Liberation Army, the Central Millitary Commission, was “suspended” and the third defense minister vanished from view.

In any other large military, such actions would set off global alarm bills. More than a month after the CMC member and the the most recent defense minister vanished, there is still only informed speculation as to why this is happening, but analysts agree on one thing: all does not appear well in the Chinese military.

3. Australia, Japan ink first R&D trial on underwater tech

Two of the US allies most closely watched by China got much closer this year. Adding to the US Marines who operate from northern Australia for six months each year, 6,600 of its service members can train each year for nine weeks, Japan will now send its marines each year to Northern Australia.

In addition to the new rotational force at the beginning of the year, Australia and Japan agreed to start working together on some of the most advanced and highly classified military equipment for “strategic capabilities in robotic and autonomous systems for undersea warfare.”

4. ‘Alarming’ but ‘not surprising’: Australia reportedly left with 1 operational sub amid repairs, upgrades

This year cracks in the Royal Australian Navy submersible fleet started to appear, even as the country pushed to bolster both fleets in the longer term. The Collins-class fleet was virtually crippled as the government admitted it could only deploy one of the country’s six ageing subs. The government declared that a second boat could put to sea if necessary and claimed the fleet was meeting its operational requirements. But the news raised basic questions about whether Australia could close the capability gap between Collins and the arrival of the first boats in the AUKUS fleet.

5. Aussie Navy to double surface fleet with $7B plan, but future funding uncertain

Knowing its aging fleet of ANZAC-class destroyers and other surface assets was growing increasingly thin as a deterrent, Australia decided on a $11.1 billion AUD ($7.2 billion US) plan to double its surface fleet.

A key part of that is the General Purpose Frigate program, which has been whittled down to a competition between ThyssenKrupp Marine Systems’ MEKO A-200 and Mitsubishi Heavy Industries’ Mogami frigate. The MEKO-200 is an upgraded version of the ANZAC class ships. The Mogami would be Japan’s first sale of a major weapon system to a foreign country.
