Vimana

The Vimana (ヴィマーナ) is the flying machine Noble Phantasm used by Gilgamesh in the Fourth Holy Grail War. A gold and emerald aircraft, fueled by mercury and solar-powered by rutiliated quartz crystals, that travels at the speed of thought. The pilot throne can be withdrawn. A control column is placed in front of the throne, but as it interferes with the operation of Gate of Babylon, it is not used.

Shot down by Berserker when Archer attempted to close in and use Gate of Babylon point-blank; Berserker activated the flare dispenser, and his prana transformed the flares into homing incendiary bombs, engulfing the Vimana in fire and causing Archer to lose control.

The name "Vimana" is from India's two major epics (the Ramayana and the Mahabharata) - it is possibly not the original name used in Babylon.
