The weight and damage tradeoff of light structural plating

A brief King George V-class exchange contrasts the displacement saved by light structural plating with the vulnerability exposed when that structure was hit in action.

Question

What was the advantage and drawback of light structural plating on the King George V class?

Short answer

It saved weight, but the first combat hit to the lightly plated structure exposed the vulnerability created by that saving.

Notes

Lighter plating creates a classic structural tradeoff by saving displacement that can be allocated elsewhere in a battleship design. A combat hit to the lightly plated structure then exposed the weakness created by that saving. The passage is too brief to identify the particular ship or damage episode. It is best read as a design principle rather than a complete case history.
