Fleet Admiral is the highest attainable Flag officer rank in many militaries, most notably Earth Starfleet and its Federation counterpart. One Fleet Admiral at a time is given the title Commander in Chief.

In 2254, while examining damage to Project Pharos, Dermot Cusack remarked "That's disruptor work, or I'm a fleet admiral", which Number One agreed with, but considered Cusack holding the rank a "ghastly notion".
