Designing treaty ships for concealed wartime growth

With knowledge of future treaty cheating, how should Britain comply in appearance while preparing stronger ships?

Britain could build ships such as Nelson and Rodney for rapid machinery upgrades and exploit measurement ambiguities while preserving the appearance of compliance.

Britain would still want to look compliant because the treaty system had diplomatic value. Nelson and Rodney could be designed for faster engine upgrades, the 15-inch fleet prepared for modernization, and King George V given a heavier armament. Magazine capacity and other declared weights also offered room for dishonest accounting. Naval treaties depended on verification as well as written limits.
