Colonial Fleet
the Confederacy's naval arm
The Colonial Fleet was the naval branch of the Terran Confederacy's armed forces, older than the Confederacy itself. It provided air and orbital support from its Tarsonis platforms until the fall of the Confederacy folded its remnants into the Dominion Armada.
The Colonial Fleet was a branch of the Terran Confederacy's armed forces. Over two centuries old by the Great War, it was older than the Confederacy itself. Its members maintained a long rivalry with the Confederate Marine Corps, and fights between sailors and marines were not unheard of. (StarCraft II: Heaven's Devils)
Service and structure#
The Colonial Fleet maintained air bases on worlds such as Tarsonis, where three orbital platforms served as the fleet's primary base and staging area. Joining required an exam and a physical, the latter considered easy to pass, and its members wore space-black uniforms. The fleet's rivalry with the Confederate Marine Corps ran deep enough that brawls between the two were common. (StarCraft: Ghost: Nova; StarCraft; StarCraft: I, Mengsk; StarCraft II: Heaven's Devils)
The fall of the Confederacy#
Elements of the fleet were present in the Sara system when the protoss Koprulu Expeditionary Force arrived. A single battlecruiser, the Norad II under Colonel Edmund Duke, launched a counterattack against the protoss fleet at Mar Sara, but the protoss withdrew without giving battle. The fleet evacuated Confederate forces from Mar Sara as the zerg overran the planet, making no major effort to evacuate civilians or to prevent the protoss from purifying the surface. The fleet and the Confederate Army were then dispatched in strength to Antiga Prime, where the Sons of Korhal had subverted the colony and the defection of Alpha Squadron compounded the crisis. After six months of fighting, the rebels broke the Confederate blockade by luring the zerg to the world with psi-emitters, and the protoss arrived in pursuit and purified the planet. (StarCraft: Revelations; StarCraft: Liberty's Crusade; StarCraft: Ghost: Nova)
The Sons of Korhal assault on Tarsonis was spearheaded by a strike on one of the fleet's orbital staging platforms, and the arrival of the zerg overwhelmed the Confederate forces. As the situation deteriorated, fleet units began deserting or defecting to the rebels, and the end saw them joining the general terran retreat, some picking up stragglers regardless of political affiliation. After the fall of the Confederacy, the fleet's remnants were absorbed into the new Dominion Armada. Among its known members were Captain Elias Tudbury of the Merrimack and the medic Petty Officer Lisa Cassidy.
