Black Knights' Tanker

The Black Knights' Tanker was a tanker briefly used by The Order of the Black Knights as a temproary base of operations.

Design and Specifications
The Black Knights' Tanker is nothing more than a normal tanker that has been heavily modified to house the Black Knights' Submarine.

It was used discretely as a temproary base of operations for the Black Knights. But when they were attack, they were forced to abandon the Tanker and opened its hatch on its bow, releasing the Submarine in the process.

As such, the Tanker was seen as a base within a base.
