Question

What should a time traveler in 1925 persuade a navy to build for the coming world war?

Short answer

A radar-directed automatic 3-inch gun system.

Notes

The proposed 1925 development has to be plausible with the technology then available. A radar-directed automatic 3-inch gun system is preferred to another capital ship. The choice integrates detection, fire control, rapid loading, and a useful anti-aircraft caliber into one capability. The gain comes from improving the probability of hitting fast aircraft instead of merely adding more barrels.
