AUKUS Submarine Partnership to Boost Regional Deterrence by 2027

The AUKUS nuclear-powered submarine partnership between Australia, Britain, and the U.S. will show benefits by 2027 by enhancing deterrence in the western Pacific. Despite the high cost, the project promises strategic advantages and faster response times during crises.

The AUKUS nuclear-powered submarine partnership will start delivering benefits earlier than expected, by 2027, according to a recent report. Set to enhance deterrence and increase the count of submarines in the western Pacific, this partnership involves Australia, Britain, and the U.S. transferring a fleet of eight nuclear-powered, conventionally-armed submarines to Australia by 2050.

Despite its $244 billion price tag, some doubt the practicality of Australia's most expensive defense project. Defence analyst Ross Babbage from the Lowy Institute highlights that key benefits will materialize from 2027 when five submarines with joint crews begin operations. These submarines will boost training and readiness in the region.

By the mid-2030s, the number of forward-deployed allied nuclear submarines could double, ready to respond swiftly to crises in the western Pacific. Positioned beyond Chinese missile range, Australian-based submarines promise faster reach to conflict zones compared to those in Hawaii or San Diego.

The program's annual cost will boost Australia's defense spending to 2.5%-3% of GDP. Australia plans to purchase up to three U.S. Virginia-class submarines by the early 2030s, with an Australian-built AUKUS submarine debuting by 2040. Babbage believes this partnership lessens the need for Australia to face coercion or threats alone.
