Hornet-type: the Colonial escort warship

Alert-type

The Alert-type was a purpose-built Colonial escort warship of the First Cylon War and a sister class of the Hornet-type. Once mighty line vessels, the Alert-type ships were relegated to escorting the newly built Jupiter-class battlestars, and at least one was retrofitted as a hospital ship.

Battlestar Group: the Colonial Fleet's core formation

A Battlestar Group was a naval formation of the Colonial Fleet built around a battlestar and its escorting warships. Battlestars rarely transferred between groups, and the most storied groups carried a prestige comparable to that of a historic infantry unit.

Colonial Fleet

The Colonial Fleet was the naval arm of the military of the United Colonies of Kobol, founded during the Cylon War to unite the forces of the Twelve Worlds. At its height it numbered some 120 battlestars, yet a single Cylon exploit reduced it to two ships in the opening minutes of the Fall.

Cylon War

The Cylon War, also called the First Cylon War, was a twelve year interstellar conflict between the Cylons and the Twelve Colonies of Kobol. It began when the Cylons rose against their human creators and ended in a sudden Armistice that held for over forty years.

Raptor

The Raptor was a series of multipurpose craft developed by the Colonial Fleet during the First Cylon War. Originally a sublight shuttle, it evolved into an FTL-capable platform flying everything from transport and reconnaissance to search and rescue and armed assault.

Adrasteia

Adrasteia was a civilian ship that escaped the Fall of the Twelve Colonies as part of the ragtag fleet. It carried roughly 765 crew and passengers and survived into deep space about a year after the Fall.
