The London is a Samurai class Shipkiller used by Earthfleet in the defense of Sol Space. It's captain is the ever venerable Commander Moses, and it's ships AI is Karl. The London is most notable for the noble sacrifice its captain made during The Battle of the Haven in order to protect the other ships in their battle group from a surprise, flanking attack that threatened to destroy Sevok's formation and collapse their defensive line, taking out three enemy battleships in the process at the loss of his own ship.
