Kaldar

The heavy cruiser to backup the Jaldun general cruiser platform. Mostly seen when combat is expected. The basic Kaldar is considered obsolete and has been replaced in production by the Kaldar-bis; all existing vessels are believed to have been refit. Tougher than the Jaldun and better armed, the Kaldar has no better sensors or accomodations. The introduction of the Renaissance, and it’s early strong showing- seemingly almost as capable a fighting ship on a hull two thirds the size- perhaps prematurely doomed the base model.

At least one ship of this class was refit with a cloaking device, recovered from General Chang's Bird of Prey during events depicted in Star Trek VI, and used in an attempted first strike operation against the Federation during the "Grey October" crisis. The crew defected rather than carry out their mission and the Federation came into possession of the ship.
