Was Dreadnought essentially a scaled-up HMS Antrim with larger guns and improved fire control?
Short answerDuke of Edinburgh is the closer hull comparison, while Lord Nelson supplied the readily available 12-inch guns and associated fire-control development.
NotesThe answer refines rather than rejects the viewer's comparison. HMS Antrim shows an earlier arrangement, but the Duke of Edinburgh-class armoured cruiser is presented as the closer model for Dreadnought's hull, superstructure, and turret distribution. Fisher then drew on 12-inch guns already being produced for the Lord Nelson class instead of waiting for a proposed 14-inch weapon. The result combined cruiser-derived form with battleship-calibre weapons and fire-control experience. Looking across ship types is therefore essential to seeing why Dreadnought could be completed so quickly.
