Adeptus Mechanicus Seal

Icon of the Mechanicum

The Jocasta was an Imperial pattern of anti-gravitic vehicle used as a fast Attack Craft by the forces of the ancient Mechanicum. It was deployed during the era of the Great Crusade and the Horus Heresy.

There is little other information on the Jocasta in Imperial records and it is unknown whether the vehicle is still employed by the Adeptus Mechanicus of the 41st Millennium.
