Question

How heavy would the proposed Royal Navy 15-inch/50 gun have been compared with the 15-inch/42 Mark I?

Short answer

It would have been heavier, by roughly 15 to 16 percent in the estimate given, despite using the latest postwar design practice.

Notes

The proposed 15-inch/50 used design practice from around 1919, but remained heavier than the 15-inch/42 Mark I. The recalled difference is about 15 to 16 percent overall. That figure is an estimate from memory.
