The demolition drone was a type of starship operated by the Romulan Star Empire in the 2250s of the alternate reality created by the temporal displacement of the Narada. Demolition drones had a single mode of attack; making suicide runs on enemy targets, upon impact they created large explosions which could also damage other nearby targets. Demolition drones, and their smaller counterparts, ramming drones, made up part of the Romulan force that battled starships of the Federation in the 2250s. (TOS video game: D-A-C)
