**Description**: The BC-307 Excalibur Class is the first true leap in Earth Starship Design since the BC-304. At nearly a kilometer it dwarfs all other Earth ships. These huge ships are true Capital Ships heavily armed and capable of undertaking almost any mission needed of them.

The Excalibur class is designed to work independently or at the center of a large Carrier Group type formation. They carry the largest Air Wings, the biggest crews and are capable of carrying a large amount of ground based assault vehicles, Such as tanks and armored personnel carriers. The 307 officially went into production in 2021.

The 307s design is a departure from the norm, bulkier in order to accommodate both a large air wing but also large storage areas. Unlike naval Super carriers the ship is also heavily armed, it was thought unrealistic to rely solely on the air wing and escorts to protect her. As such the 307 is the largest mobile weapons platform ever built by humans.

Despite heavy losses to the class, four in 2023 alone, four more vessels are currently planned. However they are facing cost/benefits studies, and may end up being canceled. In late 2023, plans to develop an upgraded Mark II version of the 307 were given the go ahead in hopes of making the vessel cheaper, more effective and more durable.
