The Plutona was a burrowing assault drill used to deliver troops in subterranean assaults during the Great Crusade and Horus Heresy. Unlike the larger Mantolith, the Plutona lacked internal teleportation chambers. During the Siege of Terra several were used by the Sons of Horus for the attack underneath Saturnine Gate.
