The second robot-based project, the land mobile battleship <Grand Dion>. Two flight decks reminiscent of an aircraft carrier, a rugged bridge with radars on the left and right, decks with handrails, and 10 gigantic crawlers that support the huge body, whipping up dust and running through the ground. It is truly a super-dreadnought battleship that runs on land.
