I. Introduction
Washington now views Australia as ‘the central base’ of its Indo-Pacific operations squarely targeted at China; and the strikes in Yemen make clear that the United States is willing and able to utilise its new base capabilities in Australia to devastating effect.[1]

Vince Scappatura documents the novel use of Australian territory in supporting US B-2 bombers en route and in return from strikes against Houthi targets in Yemen on October 17, and highlights the profound strategic significance of this event for the future role Australia may play in US strategic bomber operations in the Asia Pacific and beyond.

The global significance of B-2 strikes in Yemen

In a statement published late on the evening of Wednesday 16 October 2024 (EDT), Secretary of Defense Lloyd Austin revealed US forces had conducted strikes against five hardened underground weapons storage locations in Houthi-controlled areas of Yemen.[1] Although the US Navy also played a role in the operations, US Central Command announced the use of US Air Force B-2 Spirit long-range stealth bombers.[2]

The decision to launch strikes using the distinctive bat-wing bomber, which has been employed relatively infrequently in combat operations, contains a significance beyond the immediate conflict with the Houthis and carries implications that have assumed greater importance in light of the results of the recent US presidential election.

In the first instance the strikes signal the possibility of a larger conflagration in the Middle East, with the B-2’s unique combination of stealth and ‘bunker buster’ capabilities sending a clear message to Iran about America’s commitment to the defence of Israel; a commitment Washington has made even as Israel has taken a series of escalatory steps against Iran that have placed the region on the brink of all-out war.

However, they also carry a broader significance in demonstrating the ability of the US Air Force to deliver devastating strikes worldwide, including nuclear strikes due to the dual-capable role of the B-2, which is particularly salient for any future operations against both China and Russia.

Moreover, the B-2 strikes have momentous strategic implications for Australia, although this fact was left unexamined in media coverage of the event.

The Australian Department of Defence (hereafter Defence) confirmed to the Australian Broadcasting Commission (ABC) that Australian airspace and airbases were accessed in support of the strikes.[3] This participation marks the first time since World War II that Australian territory has been directly used to support US strategic bomber operations.

This novel use of Australian territory follows significant infrastructure developments at airbases across the north of the country, still ongoing, that are ultimately being developed to enable full-spectrum support for US ‘deterrence’ operations against China.[4]

The B-2 strikes in Yemen are the first active demonstration of these developing capabilities and a harbinger of more comprehensive Australian support for any future US strategic air operations, including potential nuclear missions, perhaps in the Middle East, but also ultimately against China and even Russia.

The Australian government is yet to acknowledge the profound strategic implications foregrounded by the strikes in Yemen, while Defence has been unnecessarily opaque about the details of the operation. A full account and wide understanding of Australia’s role in the strikes and what it portends are crucially important for democratic transparency and accountability, while the spectre of the forthcoming Trump administration contributes to the urgency.

Trump’s erratic and unpredictable decision-making, combined with the president’s sole authority over the use of nuclear weapons, highlights the risks of the United States, and by implication, Australia, becoming engulfed in a fateful conflict that is neither anticipated nor desired by their respective peoples. If there was a time for Australian political leaders to be forthright about the dangers of positioning Australia in the frontline of US strategic bomber operations it is now more than ever.

A rare bomber strike; and a message to Iran

As the only US bomber capable of long-range stealth strike operations, the US Air Force is highly selective in the employment of its relatively small and expensive fleet of 19 B-2 strategic aircraft. The last time the B-2 was used in combat was January 2017, when two bombers were deployed from Whiteman Air Force Base, Missouri, to conduct strikes against Islamic State targets in north Libya.[5]

The reason for employing the B-2 in strikes in Yemen, according to a Pentagon spokesperson, was because of its ‘unique capability and ability to carry a large payload to deliver munitions that could penetrate and strike these deep underground facilities that were storing components that the Houthis have been using.’[6]

Justified as degrading the Houthis’ ability to attack vessels transiting the Red Sea, US Defense Secretary Lloyd J. Austin declared:

This was a unique demonstration of the United States’ ability to target facilities that our adversaries seek to keep out of reach, no matter how deeply buried underground, hardened, or fortified. The employment of U.S. Air Force B-2 Spirit long-range stealth bombers demonstrate U.S. global strike capabilities to take action against these targets when necessary, anytime, anywhere.[7]

The Pentagon refused to divulge the specific type of ordinance that was employed in the strikes, although an anonymous source revealed to a specialist military journal that the B-2s dropped 2,000-pound BLU-109 JDAM ‘bunker buster’ bombs.[8]

Of particular significance for Iran is the fact that the B-2 is uniquely capable of employing the 30,000-pound GBU-57 Massive Ordinance Penetrator (MOP) in combat operations, reportedly reaching targets of up to 200 feet underground.[9] Iran’s nuclear facilities are known to be deeply embedded underground at Fordow and Natanz and could only plausibly be destroyed by the employment of the MOP.[10]

Although Iran wasn’t mentioned by name, the Pentagon made it clear that the employment of the B-2 was not only a message to the Houthis but any ‘potential adversaries that hide things deep underground. It’s a message to them as well.’[11]

An historic first for Australia

Although aspects of the Australian role in supporting the B-2 strike mission remain unclear, the fact that it prefigures future support for a range of US missions involving conventional and nuclear forces in contingencies anywhere in the world demands a full account and understanding.

Australia is the only foreign country publicly known to have provided direct military support for the B-2 strikes in Yemen. Moreover, achieving this level of logistical cooperation represents a significant milestone in Australia-US military cooperation.
