The Daedalus Class is used by many Earth Nations in various functions, from support ship in larger military's, to Flagship of smaller ones. Combining the role as a Battle Cruiser and Deep Space Carrier. It has the highest production numbers of any Earth vessel, and currently the mainstay in many fleets. While the technology is beginning to show age, many of the improvements are found in newer DD-306 and BB-307s. While there are some variations between individual ships, there are generally 3 version, the Mark I was introduced in 2005, the Mark II featured the integration of the Asgard upgrades and began with the USS George Hammond. The Mark III began introduction in 2015 featuring improvements in weapons, propulsion and other systems. The price tag for a BC-304 Mk I during the covert stages of the Stargate Program was estimated at roughly 7 billion dollars for the RFS Korolev alone, a price tag that fails to include research and development, or the cost of specialized support facilities for such a creation.
