Galaxy-Class Starships are a type of starship in the Star Trek universe, primarily used by the United Federation of Planets. Introduced in the late 24th century, these vessels are designed for deep-space exploration, scientific research, and diplomatic missions. They are known for their large size, advanced technology, and ability to carry a significant crew and passengers. The most famous example of a Galaxy-Class Starship is the USS Enterprise-D, which served as the main setting for the television series Star Trek: The Next Generation. These starships feature a saucer-shaped primary hull, a secondary engineering hull, and warp drive capabilities, allowing them to travel faster than light.
