Rear admiral is a flag officer rank used by naval organizations, traditionally below the grade of vice admiral. This rank was used by the Federation Starfleet as well as its predecessor the Earth Starfleet. Some systems instead used two tiers of rear admiral rank, "Rear Admiral, Upper Half" and "Rear Admiral, Lower Half."
