Over the next decade, the AUKUS submarines are projected to cost up to $63 billion.
The government is planning to invest significantly in ‘autonomous and uncrewed maritime vehicles’ as part of AUKUS Pillar II. Submarines equipped with conventional armaments and nuclear-powered engines, along with associated infrastructure, will receive funding of $53 billion to $63 billion (US$34 billion to US$41 billion) over the next decade, according to the Australian government. The infrastructure mainly consists of a nuclear-powered submarine operating base in Western Australia.
Australia’s focus on enhancing its long-range naval capability is a key aspect of the National Defence Strategy. Defense Minister Richard Marles, while announcing the latest strategy, emphasized on ‘projecting’ rather than just defending the country. The strategy also shifts from deterrence to denial, with denial strategy aimed at making the opponent’s objectives unattainable, irrespective of their pursuit.
Another $51 billion to $69 billion will go towards maritime capabilities for sea denial, with a focus on expanding the Navy’s surface combatant fleet. This expansion will include 36 MH-60R Romeo helicopters costing $2.4 billion to $2.7 billion, in support of additional major vessels.
To enhance the Navy’s long-range strike capabilities, they will acquire the Tomahawk weapon system from the United States. Additionally, the acquisition of next-generation Evolved Sea Sparrow Missile Block II and SM-2 and SM-6 missiles for various classes of vessels is also planned.
Autonomous lethal vehicles will receive a substantial investment of $5.2 billion to $7.2 billion, primarily focusing on subsea warfare capabilities. These investments will be made through AUKUS Pillar II Advanced Capabilities which involve sharing the latest technology in defense and space.
Furthermore, there will be additions to the Navy’s fleet of Bluebottle remotely piloted unmanned surface vessels and upgrades to the current fleet of Collins-class submarines. Additional funding is allocated for sea-based strike, electronic warfare capabilities, and maritime command systems to enhance the Navy’s capacity to target adversary aircraft and missiles over longer ranges.
