The Retaliator is a strategic bomber developed by Aegis Dynamics for the United Empire of Earth Navy (UEEN). Variants of the spacecraft have been used in the UEEN for three centuries. Despite distinguishing themselves in various operations such as the Battle of Idris IV (2544), they are most commonly associated with the abuses of the Messer regime (2546 - 2792). The current model of the Retaliator was built with modular bays which allow it to be converted from its original role to service as a cargo or dropship. Civilians are known to extensively customize surplus Retaliators for non-wartime roles.
