Australia officially announced on October 19, 2026, that its Ghost Shark autonomous submarines will be armed with Altius aerial drones and advanced sea mines, a development that significantly enhances the nation's defense capabilities and forms a key part of the AUKUS defense pact. This move is part of a current A$1.8 billion (approximately US$1.3 billion) contract for a fleet of Ghost Shark submarines.

This development strengthens Australia's strategic posture and its contributions to the AUKUS defense pact, particularly under Pillar II, which focuses on advanced capabilities. The new armaments allow the Ghost Sharks to conduct reconnaissance, strike missions, and expand undersea warfare options without crewed vessels, which is critical for deterrence and operations in the Indo-Pacific region.

The program operates under a contract valued at A$1.8 billion (about US$1.3 billion) for a fleet of these autonomous submarines. This collaborative effort involves the Royal Australian Navy, the Defence Science and Technology Group (DSTG), and Anduril Australia. The initiative is a key component of AUKUS Pillar II, which focuses on advanced military capabilities. Defence Industry Minister Pat Conroy indicated that the payloads were approved following secret trials.
