Beauty of exterior design was emphasized in the Mother Vanguard as it was built with the noble principles of Cosmo aristocratism. The design also emphasizes elegance, and its appearance with a mast is reminiscent of a sailing ship. A golden goddess statue is engraved on the bow, and a beam flag can be deployed from behind the mast. However, it is not just specialized in design, but the internal mechanism is luxuriously incorporated with the latest technology of the time, and it boasts high performance as a space battleship. Among them, the Minovsky Drive is the latest technology at the time of construction, and although it is the size of a spaceship class, it is capable of long-distance navigation comparable to interplanetary navigation vessels. The Minovsky Drive is a top secret technology that is not installed in other ships of the same type, so the Mother Vanguard is usually propelled by a thermonuclear rocket engine like a conventional ship to hide its existence.
