The Australian Department of Defence disclosed on 19 October that Ghost Shark, the extra-large autonomous submarine built with Anduril, can carry up to twelve sea mines at a time1. Two other previously classified payloads were revealed alongside it: Anduril's Altius aerial drones, launched from the vehicle, and supply caches for special forces. An Altius can scout, or carry about 4kg of explosives against a vessel.
"Those Ghost Sharks now have teeth," said Pat Conroy, the defence industry minister. He named payloads as Australia's export focus under AUKUS Pillar Two, the strand of the Australia-UK-US pact covering shared advanced technology rather than nuclear submarines. Conroy said he "hasn't given up hope" that Britain and the US take an interest in the vehicle itself. The first boat arrived in January this year under an A$1.7bn (about £873m) contract, and Defence says "dozens and dozens" will follow.
Uncrewed minelaying has a recent precedent: a MARLIN uncrewed vessel laid a MALAMAN training mine in August. Ghost Sharks also sailed in the Maritime Big Play exercise off San Diego.
