​X. Ships of Class
​The following registries constitute the production run for the Empress-class Dreadnought line:
​USS Empress, NCC-84900 [Class Ship]
​USS Atlantis-A, NCC-74601-A [Active Flagship - Registry carryover via Presidential Decree]
​USS Majestic, NCC-84901
​USS Sovereign II, NCC-84902
​USS Imperator, NCC-84903

​XI. Conclusion
​The Empress-class dreadnought represents the logical evolution of Starfleet capital ship architecture heading into the fifth year of the 25th century. By taking the lessons learned from the Dominion War and the post-Frontier Day rebuilding initiatives, the USS Atlantis-A balances raw tactical dominance with the scientific curiosity that defines the United Federation of Planets. With its distinct tri-nacelle layout and deep-space capability, the Atlantis-A stands ready to defend the final frontier well into the next century.
