Zephyr class

For other uses, see Zephyr.

The Zephyr-class was a type of Federation heavy escort starship in Starfleet service in the 25th century, a subclass of the Steamrunner design. These vessels were usually commanded by an officer holding the rank of commander. (STO mission: "Welcome to Earth Spacedock")

History and specifications

The Zephyr-class was an escort, i.e. a Starfleet warship. Phaser cannons were standard equipment on these ships. The saucer, nacelles, mission pod, pylons and hull were interchangeable with Akira-class and Oslo-class starships. Although the Zephyr-class was derived from the Steamrunner-class, components of the two classes were not exchangeable. (STO mission: "Welcome to Earth Spacedock")
