The Fantome class is a class of eight small survey motor boats (SMBs) operated by the Royal Australian Navy (RAN) and DMS Maritime. The four-man boats are designed to operate from the Leeuwin-class survey vessels, with three assigned to each ship, while the seventh and eighth were attached to the RAN Hydrographic School at HMAS Penguin. They are fitted with navigational and survey equipment and are unarmed.
