Black Knights' Submarine

Prior to giving the Black Knights the Ikaruga, Kyoto provided them with a high-speed submarine, which is simply known as "Black Knights' Submarine" (黒の騎士団潜水艦, Kuro no Kishi-Dan Sensuikan) which served as the Black Knights' base during their time in Area 11. The status of the Black Knights' Submarine following the Black Rebellion is unknown, but it was mostly likely replaced by the Ikaruga.

Design and Specifications
Designed for the Black Knights, the submarine was provided by the Kyoto House. It houses all of the Black Knights members and has an array of rooms including the command room and cafeteria. It also has storage room to store various cargo as well as knightmares. For weapons, the submarine is equipped with six torpedo launchers and cruise missile launcers with detonators. Additionally, it has two Slash Harken-like anchors and stealth system as a result from the Gefjun Disturber.
