The largest and most powerful of Romulan spacecraft, first detected in late 2364 by the Federation in the first Romulan meeting in 53 years. The largest and most powerful of Romulan spacecraft, the D’deridex-class starship is nearly twice the length overall of a Galaxy-class starship, and uses an artificial quantum singularity to power its warp-drive system. Decks are lettered and sections numbered. Some quarters are on C deck; Launch Bay 3 is on Deck E, Section 25. It carries at least three shuttlecraft areas, known as "Launching Bays." Even through a cloak, warp signature may be detected at speeds above warp 6. TM & © 2021 CBS Studios Inc. STAR TREK and related marks and logos are trademarks of CBS Studios Inc. All Rights Reserved.
