Starfleet is a fictional organization in the Star Trek universe, and the exact number of ships it has is not explicitly stated in the series. However, Starfleet is depicted as a vast and powerful fleet with numerous starships at its disposal, ranging from small shuttles to massive starships like the USS Enterprise. The size and scope of Starfleet's fleet is meant to convey the idea of a highly advanced and expansive organization capable of exploring the galaxy and defending the United Federation of Planets. **

There has never been a German Starfleet in reality. Starfleet is a fictional organization from the Star Trek franchise. While Germany does have a space agency, the German Aerospace Center (DLR), it does not have a military or civilian space fleet comparable to the fictional Starfleet. Therefore, there is no "German Starfleet" to speak of. **

The Starfleet from Star Trek is not realistic in the sense that it is a fictional organization set in a futuristic universe with advanced technology and interstellar travel capabilities. However, the values and principles upheld by Starfleet, such as exploration, diplomacy, and cooperation, are grounded in real-world ideals and aspirations. While the specific technologies and capabilities of Starfleet may not be achievable with current scientific understanding, the underlying ethos of the organization reflects humanity's ongoing pursuit of knowledge, peace, and understanding in the universe. **

The largest starships in the Starfleet are the Galaxy-class starships, which include iconic vessels such as the USS Enterprise-D. These starships are designed for long-range exploration and diplomacy, and are equipped with advanced technology and spacious interiors. They are among the most powerful and versatile ships in the Starfleet, capable of handling a wide range of missions and challenges. **
