G3 and N3 designs posed a fleet-distribution dilemma

Fast G3 battlecruisers could raid trade and overwhelm older convoy escorts, while concentrated N3 battleships punished an opponent that dispersed to counter them.

Question

Were the G3 and N3 classes intended to deter rival building through overwhelming individual power?

Short answer

More importantly, together they forced an impossible deployment choice: concentrate against the N3s and expose trade to G3s, or disperse and be defeated in detail.

Notes

The question links the N3s' proposed 18-inch guns and the G3s' superiority over the Lexington and Amagi designs to naval arms-race deterrence. The answer treats that claim as overstated and focuses on the operational effect. The G3s' speed, range, and 16-inch guns would force an opponent to assign powerful ships across distant trade routes, since older 14-inch battleships could not contain them and they would not face the same constraint as the German force in Operation Berlin. Dispersing the fleet against the G3s would leave local groups vulnerable to concentrated N3 battleships. Concentrating against the N3s would free the G3s to attack commerce, creating a blunt force-distribution dilemma.
