If you’re going to shoot from the sea, why, I’ll bet the people on land will be able to shoot back.

It depends on what you are shooting. If you are lobbing in Trident D5s from 7000 miles away then they have to find you before they can shoot back. Even if you are just using an old fashioned 406 mm crater maker then you have a good chance of out reaching anything they have on shore. But a 76mm requires that you get close to use direct fire. And if you are using indirect fire you can't laser guide unless you have a man on the ground. And when a tank with a 120mm, can beat you in a gun duel you have a problem.

A 76mm with its high rate of fire, is great for anti small boat work and shooting at aircraft. It is too small for meaningful shore bombardment.

It is too small for meaningful shore bombardment.

Old style shore bombardment is a thing of the past.

In general most weapons have been getting more precise with LESS destructive power.

A precise 76mm shot can destroy a target and leave the orphanage next door untouched better than a salvo of 5".
