Nelson's claimed speed versus likely service performance

The answer distinguishes the class's nominal 23-knot figure from an estimate of roughly 20 knots in ordinary service.

Question

Did Nelson and Rodney regularly make their advertised 23 knots?

Short answer

Probably not; roughly 20 knots is offered as a more realistic frequent service speed.

Notes

The published machinery figures give Nelson and Rodney a top speed of 23 knots from 45,000 shaft horsepower. The ships could claim that result, but they probably did not achieve it often in service. About 20 knots is offered as a more realistic operating figure. The distinction matters when comparing paper performance with the speed available to a fleet commander in sustained operations.
