Why the Defiant is called a guided-missile battleship

This December 2025 assessment uses the public announcements available the day after the proposal, without claiming inside knowledge of the design. The BBG designation identifies a guided-missile battleship. One interpretation of the name looks back to first- and second-rate ships of the line, whose concentrated firepower could overwhelm smaller warships, rather than requiring the dreadnought balance of armor, speed, and guns. A French frigate destroyed by a ship-of-the-line broadside at the Battle of the Nile supplies the historical example. Under that interpretation, battleship denotes the most lethal surface combatant outside the carrier and submarine categories.
