The Emerald class was a type of Tholian Assembly juggernaut starship in service in the late 24th century. (ST - The Fall novel: Revelation and Dust)


These vessels had a distinctive Tholian design with a wedge shape where the hull was a combination of straight lines and angles. Its warp drive engine took the form of a pair of shaped edged warp nacelles. (ST - The Fall novel: Revelation and Dust)


These vessels were used by the Assembly by 2385 and were deployed during the time the Tholians were allied with the Typhon Pact. Starfleet ship recognition systems had logged this type of craft within their systems. One such starship arrived by Bajor where it approached Deep Space 9 in Federation space. (ST - The Fall novel: Revelation and Dust)

Another Emerald-class starship was commandeered by Zyene when she was part of the Summit of Eight cabal. (TNG novel: Takedown)
