Star Trek: Picard: Analyzing All The Ships From Season One
4. Snakehead Scout Ship
Like the small Romulan warbirds from "Remembrance", the Snakehead scout ship is among the complement of support ships attached to the Artifact. Narek hops in a Snakehead scout ship and pursues the La Sirena through the episodes "Nepenthe" and "Broken Pieces" before the synth orchids capture and presumably destroy it at Coppelius in "Et In Arcadia Ego, Part 1".
This little ship is capable of cloaking, which Narek uses to project a mirror image of the Snakehead in battle with the La Sirena at Coppelius. According to Rios in "Nepenthe", the Snakehead scout ship is distinguished by "double subthrusters" and "massive firepower for the size". It's a also a departure from the normal bird-themed starships the Romulans traditionally employed.
