Anduril developed the Ghost Shark program with Australia, building robotic submarines at a very large scale, very quickly.

“Anduril Australia is co-developing the Ghost Shark, an extra-large autonomous underwater vehicle (XL-AUV), with the Royal Australian Navy and Defence Science and Technology Group. The program has been noted for its speed, with the first prototype unveiled in April 2024, reportedly ahead of schedule. In September 2025, the Australian government signed a A$1.7 billion contract with Anduril to acquire a fleet of these robotic submarines, with production moving from prototype to a program of record in under three years, indicating both a rapid timeline and a significant scale. Context: The program began in May 2022 as a co-funded partnership to produce three prototypes. Its success and speed led to a much larger A$1.7 billion contract in September 2025 for Anduril to deliver a fleet of Ghost Sharks to the Royal Australian Navy over five years.”
