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.
