Unnamed[]
22nd century vessel []
This 22nd century vessel was claimed to have been visited by Professor Berlinghoff Rasmussen and a colleague on one of their time travel adventures.
Doctor Beverly Crusher assumed that said vessel was an Earth or early Federation starship, as she shared her knowledge of contemporary 22nd century medical technology, stating that "they hadn't perfected quarantine fields. You probably saw some surgical masks and gloves." (TNG: "A Matter Of Time")
Beta XII-A ship []
In 2268, the USS Enterprise received a distress call from the colony on Beta XII-A in which they said that an unidentified ship was attacking them. Upon approaching the planet, the Federation starship failed to detect the ship. The distress call, and the colony, were a fabrication of the Beta XII-A entity. (TOS: "Day of the Dove")
Big ship []
In his first account of what happened to the SS Vico, Timothy, the only survivor of the research vessel, reported that a big ship attacked them. After the Vico was disabled by weapons fire, the big ship beamed over a boarding party. (TNG: "Hero Worship")
Federation-Lysian conflict ships []
According to a falsified intelligence report in 2368, over a two-month period, the crews of these fourteen Federation ships were captured and imprisoned on Lysia. (TNG: "Conundrum")
Incredible Tales rocket ships []

Several illustrated rocket ships
In 1953, Roy Ritterhouse drew an illustration for the magazine Incredible Tales of Scientific Wonder that showed a Human family being sold one of several rocket ships. (DS9: "Far Beyond the Stars")
Romulan battle cruiser []
In a holoprogram created by Barash, William T. Riker had, in 2379, saved this Romulan battle cruiser, with collapsing warp coils and failing life support, that had drifted into Federation space. This action impressed the Romulans, and was the first step toward an alliance. (TNG: "Future Imperfect")
"the girl who made the stars" alien being's ship[]
