It's not a spaceship, because it can't exist without being supported by the other copies of itself on a torus. If you were going to call that a spaceship, then infinite lightspeed waves in CGoL would also be spaceships! A spaceship needs to be able to exist in free space, which yours cannot.

Ah. I give up searching for spaceships then.
