Virasian UFO

Virasian UFOs are the main transportation vehicle of the Virasians. Virasian UFOs first appear in the 1968 Daiei film Gamera vs. Viras.

Gamera vs. Viras
An expedition force of Virasians are travelling towards Earth to prepare an invasion, when their UFO is attacked by Gamera, who sets it on fire. The Virasians try to jettison the damaged segments and fly away, but the ship explodes. Some time later, more Virasians land on Earth, this time evading Gamera. Gamera tries to attack the ship, but the Virasians successfuly escape by jettisoning the control segment and flying out of Gamera's reach. After the Lead Virasian fuses with his comrades, the UFO is presumably left defunct.

Trivia
Much like Gamera himself, the Virasian UFOs fly by spinning at high speed, emitting rockets from four engines to keep themselves airborne.
