The Kempff Fleet (Japanese: ケンプ艦隊) was a fleet of the Imperial Navy that was under the command of Admiral Karl Gustav Kempff. It was conservative and was cautious when taking action yet remained a disciplined force that was able to quickly react when required. The Fleet was nearly obliterated alongside the Müller Fleet after the destruction of the mobile Geiersburg Fortress and death of Admiral Kempff during the failed Imperial attack of the Eighth Battle of Iserlohn in April 798 UC (489 IC / 3598 CE).
