What could have made the Type 82 destroyer more economically viable than the Type 42 alternative?
Short answerA simpler power plant might have helped, but the principal issue was willingness to fund a large, capable ship.
NotesA gas-and-diesel arrangement could have been simpler and more adaptable than combined gas and steam. Machinery changes would not solve the whole problem because a ship of Type 82's size remained expensive. Affordability ultimately depended on accepting the required outlay. Design economy and programme affordability were separate questions.
