After the Temporal incursion in 2421, the USS Icarus was build to combat any further Terrain Invasions. The ship was sent to patrol areas the Terrains had used as "breeding grounds" to open Temporal Rifts and supply themselves with infinite reinforcements.
After over a decade of patrols, the Icarus was called to aid the Romulan Republic in the Solanae Dyson Sphere in an effort to hold back and defeat the growing Voth Threat.
