The Doppler-class was a type of scout starship in service to Earth Starfleet and Federation Starfleet in the mid-to-late 22nd century. (TOS reference: Spaceflight Chronology)
Service history[]
The Doppler-class had a crew of 50 and a mass of nearly 4,100 tons. It entered service on reference stardate 1/0508. Almost 490 were built. They remained in service until reference stardate 1/25. (TOS reference: Spaceflight Chronology, FASA RPG module: The Romulan War)
- Both Spaceflight Chronology and the FASA RPG use a timeline in which the Romulan War occurred nearly 20 years after the foundation of the Federation, with the Doppler-class being a ship of the Federation Starfleet. However, Star Trek: Enterprise later canonically placed the Romulan War shortly before foundation, 2155–2160. Adapting the Doppler-class to this chronology suggests that it began as an Earth Starfleet vessel, entering service c. 2151.
