The Promellian battle cruiser was a class of battle cruiser utilized by the Promellian military.


The class of starship was built for many generations prior to the 14th century. While crude by 24th century Federation standards, when this design was built, Humans on Earth were just perfecting the mechanical clock and using steel crossbows in battle.

Visiting a Promellian battle cruiser was always a dream of Jean-Luc Picard's, a dream he had held on to ever since he was a child, when he used to build model ships in bottles.

In 2366, the derelict cruiser Cleponji was discovered by the USS Enterprise-D, under Captain Picard, near the remains of Orelious IX. The vessel was immediately recognized on sight, and was considered a rare and magnificent find, as this particular ship design was one of legend among the crew of the Enterprise-D. (TNG: "Booby Trap")

In 2401, a miniature Promellian battle cruiser displayed as a ship in a bottle was kept by Jean-Luc Picard in his library at Château Picard. (PIC: "The Star Gazer")

The Promellian battle cruiser was comparable in size to a Galaxy-class starship, and featured a swept-back wing design, with large module on the tail section. The forward section extended some ways from the primary hull, and contained a raised structure near the front of the forward most section of the ship.

The ship was provided with power by power pack, with propulsion provided by Lang Cycle fusion engines. Furthermore, the ship's life support provide oxygen for breathing. (TNG: "Booby Trap")

In the script it was also noted by Picard that the ship's corridors were lined with "positron ducts [that] channeled power from one end of the ship to the other.". [1]

Interior design[]

The bridge design was considered to be well structured and sophisticated.

Upon visiting the Cleponji in 2366, Picard's initial reaction to the bridge design was: "extraordinary." He further added that, "[y]ou would expect the bridge layout of this era to be clumsy, awkward… but look at this – it is a model of simplicity. Elegant, functional. They built this craft for generations. And it worked."

During the visit, Worf took tricorder images of the ship, and was indicated to take note of the ship's tactical display. (TNG: "Booby Trap")

The interior sets were designed and built by art director Richard James and set designer Gary Speckman on Paramount Stage 16.

In a deleted scene from the script, Picard discussed with Worf and Data "how well laid out" the tactical display was, adding, "[w]e went through how many different designs before we reached this kind of sophistication…?" Data answered that, "I believe it was four, sir. We did not have a fully integrated tactical command until the 23rd century. In fact, several of the Promellian innovations served as inspiration for early Federation starship design…"

Communications room[]

The communications room contained a communications station with a display screen, and data access through the use of memory coils. (TNG: "Booby Trap")

Aside from the passage of time, the fact they were in a different section of the ship, specifically the "communications room" was only noted in the script, which described "a room with several visual monitors as well as radio and electronic equipment."



Background information[]

Little indication was given in the script regarding the vessel, other than a generic reference to "an ancient warship lying dead in space," that was made upon its discovery.
