Saiyan´s Attack Ball

Attack Balls (Atakku Bōru), also known as Round Spaceships (Marugata Uchūsen) are spaceships used by those under King Cold, Cooler, and Frieza for interstellar travel. When the Saiyans were a part of the military, these vehicles also sent low-class Saiyans to distant locations, so that they would one day conquer and destroy worlds throughout the galaxy.

Even though it is only five feet in diameter, it houses an advanced environmental system and an incredibly fuel-efficient faster-than-light drive. Those traveling inside the ball are kept in a state of suspended animation that minimizes the resources needed to keep them alive.
