Star Trek The Official Starship Collection Jem'Hadar BattleCruiser. The Jem'Hadar Battlecruiser is one of the larger ships that the Jem'hadar used on Star Trek: Deep Space Nine and is the equivalent of a Starfleet Galaxy-class vessel. The first version that appeared on screen was a physical model, which was then replaced by two subtly different CG versions, and the die-cast model is based on the last of these.This model is die-cast, hand-painted, and comes with an in-depth magazine featuring product artwork and highlighting the ship's history and design.
