The dimensions of a proposed 14-inch/70 gun

Is the proposed modern 14-inch gun bigger than the 14-inch weapons discussed earlier?

Its bore remains 14 inches. The proposed 70-calibre barrel would be 980 inches long, roughly 81 to 82 feet, with shell weight and automation also influencing the design.

The proposed weapon combines a 14-inch bore with a barrel 70 calibres long. Multiplying 14 by 70 gives 980 inches, roughly 81 to 82 feet. Shell weight and the prospects for automated loading are also part of the calculation. This long-barrelled weapon belongs to the counterfactual modern battleship proposal and differs from the earlier 14-inch guns discussed in the programme.
