The case for twin 40 mm mounts on Type 31

Should Type 31 carry more 40 mm guns?

The preference is for twin mountings rather than singles, to add firepower without a proportionate increase in mounting size or weight.

The proposal favours twin 40 mm mountings on Type 31. It questions continued commitment to single barrels when ships must face threats such as hypersonic weapons. Twin mountings are described as only modestly larger and heavier than singles. The intended benefit is more gunfire from a mounting that does not grow in proportion to the barrel count.
