The Heavy Raider is a Cylon attack and transport spacecraft. The main armament of the Heavy Raider seems to consist of a barbette of six cannons mounted under the cockpit area of the vehicle. These cannons are capable of an extremely high rate of fire. The Heavy Raiders are also capable of launching missiles.

Unlike the standard Raider, the Heavy Raider is either exclusively or optionally piloted by humanoid Cylons or Centurions, however it can apparently pilot itself if necessary.
