How would a full Type 82 class have changed the later Royal Navy?
Short answerIt would likely have led to substantially larger Type 45 and Type 83 successors rather than the smaller Type 42 route.
NotesThe cancellation that produced Type 42 would no longer shape the fleet. A Type 45 in this lineage might be several thousand tons larger than the real ship, with an even larger Type 83 following it. A complete Type 82 class would normalize a large, capable air-defense combatant instead of the smaller Type 42 compromise. Successor requirements would inherit that greater margin for sensors, missiles, endurance, and future growth.
