Cracks are already beginning to show’: AUKUS is in trouble, UK probe warns

Sydney Morning Herald

London: Leadership failures are being blamed for slow decisions and funding shortfalls that threaten the mammoth AUKUS submarine program, with a British inquiry revealing a series of problems that put Australia’s security at risk.   :(

The parliamentary inquiry warns that the problems could snowball into a severe test for the AUKUS allies because investment has faltered, political leadership has dwindled and there are now serious doubts about whether the submarine project can be delivered.



The conclusions are a wake-up call to political leaders and military chiefs in the three signatories to the pact – Australia, the UK and the US – when submarine construction is behind schedule.

“We have deep concerns cracks are already beginning to show when it comes to funding,” said Tan Dhesi, the chair of the House of Commons defence committee, which undertook the first major review of the project for the British parliament.   

“The investment pipeline has already faltered. This cannot be allowed to happen again.

“Even seemingly minor shortfalls and delays snowball over time, with potentially severe consequences for the UK and wider Euro-Atlantic security, and our standing with our trilateral partners.”



The committee, with members from all major political parties, called for faster decisions and greater action to finish the facilities needed to build and maintain nuclear-powered submarines in the UK and Australia.

While the pact sets out plans for Australia to buy at least three Virginia-class submarines from the US over the next decade, these vessels are meant to be an interim step before the UK and Australia build the new AUKUS-class fleet in both countries to a shared design.

The British government is planning to have up to 12 of the new submarines to defend its waters when it is seeing increasing incursions by Russian vessels. Australia hopes to have five vessels from the early 2040s, built in South Australia.

Dhesi, the Labour MP for Slough, backed the fundamental case for AUKUS despite the changes in world politics over the year since the inquiry began.

“Any undertaking of this scale requires committed, consistent political will and leadership,” he said in a statement upon the release of the report.

“Unfortunately, we found that the UK’s political leadership on AUKUS has dwindled. AUKUS can’t be seen as just another defence programme; if it is to stay on track then leadership must come from the very top.”

Australian Prime Minister Anthony Albanese on Tuesday played down the concerns raised in the report.

“There is support overwhelmingly from the British government, from Prime Minister Keir Starmer down, as well as from the defence personnel in the United Kingdom,” he said. “AUKUS is – to quote [US] President [Donald] Trump – full steam ahead, and I’m very confident that it will be so.”

The inquiry concluded that British Prime Minister Keir Starmer had to play a “more visible role” in promoting AUKUS – and that more control needed to come from his office rather than the Ministry of Defence.

The report identified weaknesses in two major construction and maintenance bases in the UK at Devonport (near Plymouth) and Clyde (north of Glasgow) to ensure the Royal Navy could deploy submarines as promised.

“AUKUS has already started to hit bumps in the road. Submarine availability is critically low,” Dhesi said.

“Without urgent infrastructure improvements at HMNB Devonport and HMNB Clyde the government risks finding itself unable to meet its obligations under AUKUS.”



The key construction base for the AUKUS fleet in Britain is at Barrow-in-Furness, north of Liverpool, but the committee said the government was behind schedule in building the workforce and facilities needed to deliver the vessels.

The report was released at midnight on Monday in the UK (9am on Tuesday, AEST) after a year of review including testimony from ministers, defence officials and military experts.

Britain has committed £16 billion (about $30 billion) to AUKUS projects. This includes £4 billion for BAE Systems, Rolls-Royce and Babcock to design components for the SSN-AUKUS, another £3 billion for manufacturing at BAE and Rolls-Royce'

We should go back the the French, cap in hand, apologise for being so stupid as to ask to rip out the nuclear power plant from your subs and replace them with diesel.

What were we thinking?!!!!

So sorry, please can we make a new deal?  :)

Indeed

But if we want proper submarines, ie nuclear ones, they have to be integrated with the US and the UK, not with a fourth-rate non-power like France.
Japan should join AUKUS. JAUKUS.

Ripping out the nuclear reactor and replacing it with diesel is not an option as a diesel fuelled boiler cannot be used submerged.
The subs do not have a nuclear power plant they have a steam power plant whose water is boiled by the reactor.

France or any other country that starts with an ‘F’, should join, that way the name would be more appropriate.

We have to accept that the very best we can expect from this deal is our sailors will be trained to work for the  American navy in their submarines and we will be allowed to service and support them out of Western Australia.

No assurances Australian sailors will be trained to service  the American submarines but the trickle down effect will always see Australians making the Americans coffees and meals.


In return, depending on American politicians desire we may have some  protection for our shipping supply lines.


That’s what we are signed up to and that is what will happen..

I don’t like it anymore than you do but that’s what the LNP signed us up for and what labor completely supports.

Take the US out of AUKUS.


You AUKs are on your own

You should sign up and learn how to defend your own country you fat Pom.

Why do we need deep water nuke subs?

You mean we have no deep waters around OZ, out past the continental plate?

Good place to hide when nuclear war is on, better chance to survive then in big city.

Of course there is -
it would be nice if we had a whole lot of things -
we are not even energy independent -
there are many other things we need to get right before
trying to equal super power status with nuke subs.

Not necessarily, although it would be a change of unimaginable magnitude

Our biggest trading partner is china 🇨🇳.

They are also closer in our region.

Take the American bases out of Australia and replace them with Chinese ones and the balance of power in  both the pacific and Indian oceans shifts incredibly.
It was less than a century ago that Australia, China and Russia allies in war.
