A Calderisi raider was a type of small ship used by the Calderisi. It had a dart-like appearance and had standard warp nacelles.
In 2371, the USS Defiant intercepted a Calderisi raider that was believed to be transporting illegal weapons to the Maquis. The Calderisi firesd on the Defiant and used a weapon that drained the Defiant of its power, although the Defiant was eventually able to destroy the ship by a well targeted torpedo fired by Kira Nerys.
