3 RAN Officers Graduate US Nuke Sub School

Australia's government owned ABC News, July 8, 2023 reports:

"Inside 'nuke school', the elite US training ground preparing Australian submariners for an AUKUS future"

In America's deep south, a group of students has just completed one of the most rigorous academic programs in the US military.

And for the first time, there were Australians among them.

Three members of the Royal Australian Navy have graduated from the Nuclear Power School in South Carolina, more commonly known as 'nuke school'.

The training pipeline was established with the US as part of the AUKUS agreement, under which Australia will obtain its own nuclear-powered submarines.

"It's a historic event for our Navy, an historic event for our submarine force and I think it's an historic event for our nation," said Australia's Chief of Navy, Vice Admiral Mark Hammond.

"Two years ago, this wasn't on the radar.

"And we've come a long way in such a short period of time but there's a lot more work to do."

Years out from Australia's acquisition of nuclear-powered subs, the graduation is an early step towards making AUKUS a reality.

But there are still major hurdles ahead when it comes to the broader workforce challenges presented by the plan.

Inside 'nuke school'

The three Australians — Lieutenant Commander James Heydon, Lieutenant Commander Adam Klyne, and Lieutenant William Hall – started at the Nuclear Power School in November with the aim of eventually qualifying to operate the reactors onboard nuclear-powered submarines.

Lieutenant Commander Heydon described the course he's just graduated from as a "four-year engineering degree crammed into six months".

"Maths, physics, thermodynamics, fluid dynamics, radiological controls, to how do we safely steward and manage the nuclear plant and the nuclear by-products, are I guess aspects of what we've been learning here," he said.

"My experience [in the Australian Navy] was ship design and ship construction.

"While they were aspects here, it was very foreign. So it was … a crash course into the deep end, sink or swim, and we all swam."

The Australians will now have to complete another set of practical learning, which will include spending time on retired nuclear-powered subs known as moored training ships.

After that, they'll receive further training in Connecticut before being assigned to a Virginia-class sub.

"The plan at this stage is to join submarines based in Pearl Harbor, Hawaii, and they'll complete their training at sea," Vice Admiral Hammond said.

"Ultimately, we need them to pay their skills forward.

"So once they're qualified, sufficiently experienced, then we'll get them back into the ecosystem in a different role."

AUKUS presents major workforce challenges for Australia

The AUKUS plan, announced in San Diego earlier this year, will see Australia acquire a total of eight nuclear-powered submarines at a cost of up to $368 billion. 

US submarines are increasing their visits to Australian ports from this year, and from 2027 HMAS Stirling naval base in Western Australia will host rotations of American and British subs under what's known as 'Submarine Rotational Force-West'.

Australia is expected to buy at least three Virginia-class submarines from the US from the early 2030s, before building its own nuclear-powered boats in Adelaide to be known as SSN-AUKUS.

They will be based on a British design using US technology, with the first scheduled to be delivered in the early 2040s.

Retired submariner and senior fellow at Washington-based think tank the Hudson Institute, Bryan Clark, described it as a "crawl, walk, run" approach.

"The biggest challenge is going to be transitioning from having some Australian-owned, US-built submarines … to having an Australian-built or at least a purpose-built Australian nuclear submarine," he said.

"It's going to require a massive amount of infrastructure, incredible workforce demand, both in terms of technical skills and numbers.

"It just seems like that's going to be a pretty heavy lift on the part of Australia to do nuclear ship construction."


The federal government says AUKUS will create 20,000 jobs over 30 years across the Australian Defence Force, the public service and industry, including roles such as tradespeople, engineers and project managers.

The number of Australian submariners will also need to be increased, with nuclear-powered submarines carrying larger crews and requiring personnel trained to operate the reactor onboard.

"The submariners that come out of Australia are very smart, very capable, fully able to take on that challenge of becoming nuclear plant operators," said Mr Clark, who is also a former executive officer of one of the moored training ships in Charleston.

"The difficulty might be in getting the numbers that you need to be able to man a nuclear submarine."

Virginia-class submarines carry around 132 people, nearly three times the size of the crew onboard the Collins-class boats Australia has now.

And unlike the Collins, nuclear-powered subs do not need to surface regularly to recharge, meaning they can stay submerged for months at a time.

AusAustralia will continue to operate its Collins-class submarines for the orefforseeable future.

Vice Admiral Hammond acknowledged the scale of the task confronting the Navy.

"We were already focused on recruiting, increasing the size of the submarine force and then initially bleeding across in smaller numbers into the nuclear power program and then scaling up as we go," he said.

"So it's a complex challenge, especially given the workforce environment back in Australia.

"Every company, every organisation wants talent. So we'll be focused very, very clearly on recruiting and retaining."

Could Australia set up its own nuke school?

More Australians are expected to follow in the footsteps of the first three graduates in Charleston, while Navy personnel are also training in the UK.

But Vice Admiral Hammond said Australia could eventually host its own training program.

"I think if we're serious about developing a sovereign nuclear submarine capability, then in time, definitely, all parts of the ecosystem built and operated by Australians in Australia, that should be the aim point," he said.

"But we don't need it all at once."

Asked where it could be located, he said the "sensible approach" would be either Adelaide or Perth.

The new subs will be built in South Australia, while Western Australia's HMAS Stirling is undergoing an $8 billion expansion.


[Fleet Base West, just south of Perth, known as] HMAS Stirling is Australia's largest naval base. ()

"They will be the two centres of excellence, if you like, for naval nuclear propulsion in Australia," Vice Admiral Hammond said.

"If you cast our minds forward, probably another 10, 15, 20 years, then the majority of the nuclear-trained submariners will be in the home port of the submarine force.

"There'll be a large number in Adelaide, but most of the boats won't be in Adelaide. So through that lens, probably WA.

"But that's a decision for governments and probably a decision for next decade, I'd imagine."

Challenges lie ahead to bring AUKUS to fruition

Aside from skills and workforce issues, there are other major challenges that still need to be overcome to bring AUKUS to fruition.

The sale of Virginia-class submarines to Australia requires the approval of the US Congress, and significant changes are needed to a complex set of export controls restricting how sensitive technology is transferred.

Questions also remain over how the US will deliver the promised Virginia-class submarines, given the pressure its own shipyards are under to meet local demand.

The US Chief of Naval Operations, Admiral Michael Gilday, last month said it was "too early" to provide an answer on exactly where the subs would come from.

"I wouldn't expect them to start identifying submarines by name or by hull number just yet; we've got time to work through that," Vice Admiral Hammond said.

"But at the moment, there is a deep tripartite commitment to doing this."

Hey Pat,
The level of Math and science required to operate a nuclear reactor and Nuclear submarine is why Submarine Engineers have Masters degree. Here's the Math that's required to operate them

Hi Nicky (please call me Pete. Only my pet Wombat calls me "Pat" ;)

Thanks for the link https://www.navsea.navy.mil/Home/NNPTC/powerschool.aspx to the Curriculum to the USN's Nuclear Power School, which in summary includes:

"Mission: Train officer and enlisted students in the science and engineering fundamental to the design, operation and maintenance of naval nuclear propulsion plants.

The naval nuclear program is widely acknowledged as having the most demanding academic program in the U.S. military. Academics proceed at a rapid pace with high academic standards enforced in all subjects. Students typically spend 40-45 hours per week in the classroom with an additional 10 to 35 hours per week of study outside of lecture hours.

Topics include:
Mathematics
Nuclear physics
Health physics
Reactor principles
Material science and metallurgy
Electrical power theory and generating equipment

Hi Pete,
That's why for Australia, if they want to embark on Nuclear Submarines, they have to up their level of Education required to work on Nuclear Submarines. They would really have to get the Countries Education system to up their Math and science education to be able to operate Nuclear submarines.

The education to run an AIP/Diesel Sub is one thing but to run a Nuclear Submarine, one has to have at least a Bachelors degree in Engineering or a STEM degree. Just look at the Math that's required and I'll bet not many of us can pass it.

That's why the US Navy pays a HUGE amount of Money for Nuclear trained Submariners including having the strictest education requirements including having Trigonometry, Calculus, Physics and Chemistry. The US Navy won't talk to a high school student about the Submarine community unless they have passed Trigonometry, Calculus, Physics and Chemistry

Hi Nicky at 7/10/2023 7:49AM

Yes for future Australian nuclear navy officers Australia will need to make a huge STEM investments beginning with scholarships for students just entering high school and then on to Science/Engineering degrees.

However changeable US presidencies and changing US strategic priorities (in the shape of an increasing challenge of higher quality Chinese nuclear subs from the late 2020s) may see the US withdrawing its offer of Virginias to the Australian Navy in the 2030s.

I think it more likely that 6 to 8 mainly UK designed SSN-AUKUS https://en.wikipedia.org/wiki/SSN-AUKUS will be what Australia recieves and that is in the 2040s.

Hi Pete and Nicky
Nothing abnormal
Sounds very similar to any training of an Engineer in five Years (3/4 years general followed by a 5th year in Nuc (MS degree , Diplom Eng, Diplôme Ingenieur the norm in Europe).In most countries the quite competitive selection process for Naval Officer, is Science based and last 5 years.
Many Naval School degrees offer an MS in Engineering. I have met numerous Ex Naval officers in Indudstry that after 10 to 15 years move to civilan eng / mgt jobs (part of the Navies problem)
They are appreciated for their tech competence but also their leadership skills

Nicky said...

That's why for countries who have AIP/Diesel subs have a different education requirements but for Nukes, you defiantly need a Bachelors and Masters degree to run a Nuclear submarine. In the US Navy, almost everyone who comes on board a Nuclear submarine is a petty officer and above. No one below E4 is allowed on a Nuclear submarine. For officer's they have to take the same exam as Nuclear operators at a Nuclear power plant that the US dept of Energy's U.S. Nuclear Regulatory Commission.

I think for Australia, they should start investing in STEM degrees and push for more STEM majors in college.

Thanks for bringing your more direct knowledge of submarine and broader naval engineering qualifications to this issue.

As you say another requirement of a senior submarine engineer is leadership ability - encouraging more junior engineers and technicians in a submarine's engineering division to work together smoothly.

Thanks Nicky at 7/12/2023 5:38 AM

Australia will find US nuclear sub reuirements particularly daunting.

I'm under the impression that Austalia's available for operations submariners has often hovered at around 240 and this includes many officers without engineering qualifications and many junior ratings. This is enough for 4 x 58 crewman Collins diesel subs operational at any one time.

Even 3 x 135 crewman Virginia for Australia in the 2030s requires a major increase to 405 operating and probably well over 1,000 in various stages of training on the very new nuclear sub technologies.

As you indicate the average submariner rank will rise further from junior petty into senior petty officer levels. Also Australia will be required to adopt US standards of all commissioned officers having a Bachelor in Nuclear Engineering Degree at a minimum and a third of those will be Masters level.

I suspect Australia will be taking on this huge SSN defence load for reasons that will only be explained to the Australian public in the late 2030s...

To Nicky
for your info many former N sub officers or petty officers are found in the civilian N sector in France in particular at EDF (Electricity prod.)

Very "stable" people,engineering trained, moving after 10 to 15 years, in their thirties, toward highly paid, in the countryside (ie not in the inner cities) ,jobs! ( without any risk of lay off !)

Pete said...

Hi Anonymous at 7/14/2023 12:41 AM a problem for the career pathway of future naval nuclear engineers in Australia is that Australia has no nuclear electricity industry and with no plans to establish one.

This gap has not been publicly explored by the Australian Government.

One possible reason is when Australia's future naval nuclear engineers leave the naval and safety sectors they might be engaged in an independent or shared* nuclear weapons program.

* Perhaps Australia might become a nuclear weapon sharing recipient like some NATO countries. https://en.wikipedia.org/wiki/Nuclear_sharing

This is also noting Australia is now spending $100s millions a year toward NATO's Ukraine support effort and Australia is "even referred to as a "de facto member of NATO"" https://en.wikipedia.org/wiki/Foreign_relations_of_NATO#Australia
