Zvezeda-Class Shuttle

The Zvezda-Class Shuttles was a series of reusable spaceplanes operated by Roskosmos. The Zvezda-Class was the direct response to the KASA Explorer-Class Shuttle. The Zvezda-Class Shuttle itself was remarkably similar to the KASA shuttle, but they were drastically different vehicles.

The Zvezda-Class launched strapped to the side of a Zenith II rocket.

The Zvezda-class are commonly considered to ultimately be the superior of the two shuttles
