The Xindi-Reptilians have a highly-advanced warships at their disposal, with a design and power capacity second only to the Aquatics.

The Reptilians' main design during the Human conflict is a unusually delicate design with a long twin "tail." Engines are located in the pods on the forward arcing pylons, to either side of the central hull. Armament includes directed-energy beam weapons, with emitters located on the leading edge and the lower midpoint.

The Reptillians and the Insectoids led an offensive against their fellow Xindi, and Archer of Enterprise, in an effort to make sure that the Xindi weapon reached its target: Earth.
