Why the G3 design adopted a transom stern

G3's planned transom stern offered a speed gain, with stability and profile tradeoffs that help explain earlier Royal Navy preferences.

Question

Did the G3 have a transom stern, and why did earlier ships not use one?

Short answer

The later G3 design did; transom sterns could improve speed but imposed stability, profile, and institutional-acceptance tradeoffs.

Notes

The later G3 proposal included a transom stern. Its hydrodynamic advantage was to make the hull behave as though it were longer, providing a speed gain. That benefit had to be weighed against changes to stability and the ship's profile. The unfamiliar appearance of a transom stern also counted against its acceptance in earlier Royal Navy designs.
