The "droungarios" of the Imperial Fleet was raised to the rank of megas droungarios stolou ("Grand Drungary the Fleet") in the 11th century, acting as commander-in-chief of the entire Byzantine navy, until he was replaced in this task by the "megas doux" in the 1090s. The office of "megas droungarios" of the fleet continued to exist, in a subordinate position, until the fall of the Byzantine Empire. The variant rank of droungarokomēs (Greek: δρουγγαροκόμης) also existed, signifying a count ("komēs") in command of a squadron of warships.
