The Osborne Naval Shipyard was home to the construction of three Hobart Class Air Warfare Destroyers (AWD) from 2007 to 2020.

The project was delivered by the AWD Alliance with partners – ASC as the shipbuilder, Raytheon Australia as the combat system systems engineer, the Department of Defence as owner participant and Navantia as the designer and ship build manager.

The AWDs, named HMAS Hobart, HMAS Brisbane and HMAS Sydney have provided the Royal Australian Navy with one of the world’s most capable multi-mission warships capable across the full spectrum of joint maritime operations.

In September 2021, Prime Minister Scott Morrison announced the Australian Government will invest up to $5.1 billion in upgrades towards the Hobart Class Destroyer combat management system.

In November 2023, Lockheed Martin Australia confirmed it had delivered the SEA 4000 Phase 6 Combat System Design Agent contract. This update to the design architecture will support the integration of advanced Aegis Combat System capabilities into the AWD combat system upgrades.

These upgrades will take place at the Osborne Naval Shipyard from 2024 onwards and will create approximately 300 jobs in South Australia.
