The Deep Typhoon (ディープタイフーン号 Dīputaifūn-gō?) is a submarine from Sonic Rush Adventure and the fourth, and as well final, naval vessel that can be used in the game. It is a heavily armed underwater vessel that can not only handle the pressure from Blaze's world's deepest waters, but also travel the furthest of all the game's watercrafts and can battle underwater enemies. It was constructed and controlled by Miles "Tails" Prower as his third watercraft and was used by him, Sonic the Hedgehog, Blaze the Cat and Marine the Raccoon in order to reach Pirates' Island. Just like the Ocean Tornado however, the Deep Typhoon cannot travel in shallow waters.
