Australia to pursue Nuclear-Powered Submarines

Australia, the United Kingdom and the United States have agreed to the creation of an enhanced trilateral security partnership – AUKUS.

The security challenges in the Indo-Pacific region have grown significantly. Military modernisation is occurring at an unprecedented rate and capabilities are rapidly advancing and their reach expanding. The technological edge enjoyed by Australia and our partners is narrowing.

AUKUS will build on the three nations’ longstanding and ongoing bilateral ties, and will enable the partners to significantly deepen cooperation on a range of emerging security and defence capabilities, which will enhance joint capability and interoperability.  Initial efforts under AUKUS will focus on cyber capabilities, artificial intelligence, quantum technologies, and additional undersea capabilities.

This is an historic opportunity for the three nations, with like-minded allies and partners, to protect shared values and promote security and prosperity in the Indo-Pacific region.

AUKUS will complement Australia’s network of strategic partnerships, including with our ASEAN friends, our Pacific family, our Five Eyes partners, the Quad and other like-minded partners.

First initiative under AUKUS

The first initiative under AUKUS is for Australia to acquire nuclear-powered submarine technology, leveraging decades of experience from the US and UK.

Under AUKUS, the three nations will focus immediately on identifying the optimal pathway to deliver at least eight nuclear-powered submarines for Australia.

Over the next 18 months, Australia, the UK and US will intensely examine the full suite of requirements that underpin nuclear stewardship and demonstrate a clear pathway to becoming a responsible and reliable steward of this sensitive technology. Australia will establish a Nuclear-Powered Submarine Taskforce in the Department of Defence to lead this work.

Nuclear-powered submarines do not have the same limitations that face conventional submarines on weapons storage, speed and endurance. They can stay completely submerged for many months, limiting the opportunities for detection by adversaries.

As a three-ocean nation, it is necessary for Australia to have access to the most capable submarine technology available. As a nation, we are ready to take the step to pursue the most advanced submarine technology available to defend Australia and its national interests. 

Australia has no plans to acquire nuclear weapons and this proposal will remain consistent with Australia’s longstanding commitment to nuclear non-proliferation.  All three nations are deeply committed to upholding leadership on global non-proliferation.

The Government’s intention is to build the nuclear-powered submarines in South Australia, maximising the use of Australian workers.

Building the submarines in Australia is the best way to develop a strong and effective sustainment industry, which will enable us to meet every requirement to safely operate and maintain nuclear-powered submarines.

Attack class submarine program

The pursuit of nuclear-powered submarine technology means that Australia will no longer proceed with the Attack class conventional submarine program with Naval Group.

The Government would like to thank the Attack class submarine workforce, Naval Group, the Government of France and Lockheed Martin Australia for their efforts to date. However, accelerating changes to regional security make conventional submarines unsuited to our operational needs in the decades ahead.

The Government will actively work with industry to ensure the people and skills developed under the existing program are not lost to the Government’s Naval Shipbuilding Enterprise as we establish a new program to support the delivery of nuclear-powered submarines to the Navy.

The existing submarine workforce are prime candidates for the unprecedented work that needs to be performed across the Enterprise over the coming decades, where we will rely on their expertise more than ever.

The Government will partner with our Australian-owned sovereign shipbuilder, ASC, to manage and implement a new Sovereign Shipbuilding Talent Pool.

The Government is committed to finding a role within the Sovereign Shipbuilding Talent Pool for each and every skilled shipbuilding worker impacted by this announcement.

The Sovereign Shipbuilding Talent Pool will re-deploy the existing shipbuilding workforce throughout current and new shipbuilding programs, while building the nuclear-powered submarine skills that will be crucial for the success of the nuclear-powered submarine program.

This decision was not taken lightly. Our partnership with the Government of France and Naval Group on the Attack class conventional submarine program would have resulted in the most capable and lethal conventional submarine ever built.

As likeminded liberal democracies, Australia and France share a common commitment to the rules-based global order that has delivered stability and prosperity to the Indo-Pacific.

We look forward to continuing to work closely and positively with our French counterparts. France is a key friend and partner to Australia and the Indo-Pacific.

Other capabilities

The Government will also acquire additional long-range strike capabilities for the Australian Defence Force.

Throughout the decade, Australia will rapidly acquire long-range strike capabilities to enhance the ADF’s ability to deliver strike effects across our air, land and maritime domains.

These include:

  • Tomahawk Cruise Missiles, to be fielded on our Hobart class destroyers, enabling our maritime assets to strike land targets at greater distances, with better precision.
  • Joint Air-to-Surface Standoff Missiles (Extended Range) will enable our F/A-18 A/B Hornets and in future, our F-35A Lightning II, to hit targets at a range of 900km.
  • Long-Range Anti-Ship Missiles (Extended Range) (LRASM) for the F/A-18F Super Hornet.
  • Continuing collaboration with the United States to develop hypersonic missiles for our air capabilities.
  • Precision strike guided missiles for our land forces, which are capable of destroying, neutralising and supressing diverse targets from over 400km.
  • Accelerating $1 billion for a sovereign guided weapons manufacturing enterprise – which will enable us to create our own weapons on Australian soil.

These capabilities, coupled with the planned Life-of-Type Extension of Australia’s Collins class submarine fleet, will enhance Australia’s ability to deter and respond to potential security challenges.

The management of this transition, and other capability acquisition options that will meet Australia’s strategic requirements, will be at the forefront of consultations through AUKUS over the next 18 months.


Key projects confirmed for SA

South Australia will spearhead a major expansion of Australia’s naval capabilities, supporting thousands of jobs and advancing the state’s shipbuilding expertise.

A number of naval projects have been confirmed for South Australia, following the announcement today of a new enhanced security partnership between Australia, the United Kingdom and the United States.

The first initiative under the partnership, known as AUKUS, is to acquire nuclear-powered submarines for Australia, which are intended to be built in South Australia.

The Morrison Government has also approved a Life-of-Type Extension to the Collins class submarine fleet from 2026 in South Australia, and confirmed that the Full-Cycle Docking of the Collins class will continue to be conducted at Osborne. Up to $6.4 billion will be invested in these works, and around 1,300 jobs supported in South Australia.

The Government will also invest up to $5.1 billion in upgrades to the Hobart Class destroyer combat management system upgrades at Osborne from 2024, creating 300 jobs in the state.

Prime Minister Scott Morrison said the investments reinforced the Government’s commitment to South Australia’s shipbuilding industry.

“This expansion of Australia’s naval capabilities will strengthen national security, boost our sovereign workforce and support thousands of jobs in the South Australian industry,” the Prime Minister said.

“South Australia is home to some of the most skilled shipbuilding workers in the world, they have the know-how, ingenuity, industrial knowledge and determination that is required to provide our Defence Force with the very best capability.”

Minister for Defence Peter Dutton said the Government’s investments would ensure Australia maintained a strong and agile submarine capability for decades.

“The Collins class submarine to this day remains one of the most capable conventional submarines in the world,” Minister Dutton said.

“The planned Life-of-Type Extension, through the replacement of key systems, will help deliver Defence’s strategic objectives.

“The upgrade to the Aegis combat management system will ensure our fleet of Hobart class air warfare destroyers maintain their capability-edge into the future.

“Both of these projects announced today are vital for Defence’s ability to act with greater independence in an increasingly contested strategic environment.”

Minister for Finance and Senator for South Australia Simon Birmingham said the state would continue to benefit from the Morrison Government’s sovereign and continuous naval shipbuilding program.

“South Australia is the engine room of naval shipbuilding in this country,” Minister Birmingham said.

“Full-Cycle Docking and Life-of-Type Extension at Osborne will ensure we retain our skilled shipbuilding workforce, and will continue to create opportunities for local businesses to engage with the defence industry.

“In addition, the up to $5.1 billion investment in upgrading the Hobart class combat management system will create extra economic activity as well as around 300 jobs in the state.

“Conducting these sustainment projects in Osborne, on top of the building of frigates and submarines will ensure South of Australia continues to be the epicentre of naval shipbuilding in this country.”

Collins class submarine HMAS Farncomb will be the first to undergo a Life-of-Type Extension when it enters its next Full-Cycle Docking in 2026.
