Space Pirate Mother Ship

The Space Pirate Mothership is the enormous flagship of Ridley. It is also the mobile HQ for the Zebesian Space Pirates. It was only seen in Metroid: Zero Mission, where it landed in Chozodia. The Space Pirate Mothership is piloted by Ridley and doesn't seem to be piloted by anyone other than him. It also houses the giant security drone called Mecha-Ridley, a safeguard created in Ridley's likeness to protect the flagship.

The Flagship also comes with a failsafe measure if it is ever infiltrated and the drone is destroyed. Upon the defeat of Mecha Ridley, the flagship will trigger a five minute countdown, taking out any infiltrating person or battalion with itself in a massive explosion. This self-destruct system seems to be directly connected with the ship's security system.
