The United States has approved its first major submarine contract under the AUKUS security pact (the 2021 trilateral defence agreement between Australia, the UK, and the US), awarding a $275 million deal to American defence firm Electric Boat. The contract will fund engineering, technical, design, and design-transfer support activities to help Australia acquire nuclear-powered submarines. The announcement marks a significant step forward in the landmark partnership, which is widely seen as central to Australia's long-term strategic posture in the Indo-Pacific.
