Re: 3-shaft propulsion

. One has to be careful with speed and range quotes as they depend on the state of the hull (fouling). Trials info TENDED to be with reasonably clean hulls, whereas the RN standard figures usually were quoted with the hull 6 months since cleaning in temperate waters. (The RN also noted the effect of...

3-shaft propulsion

The RN looked at double reduction gearing and wasn't impressed - at that time the efficiency savings weren't great and the costs and maintenance increase weren't thought to be worth it. Post-war reports basically stated the same with the big regret being lack of reliable high pressure boilers.

As an approximation of unknown accuracy - YES

As an exact, objective measure - NO

As a relative measure - then it depends upon which others you measure.

Re: More on KGV Class main armament problems

. For a well run engineering department the normal funnel smake should vary between a light haze to dispersed light grey smoke. If a ship is hard worked (e.g. working up speed quickly) or has poorly balanced air supply then the smoke would be black and seem more voluminous. Any oil fired ship could ...

Re: More on KGV Class main armament problems

. A minor linguistic point. Guns ordered to be fired would ONLY be those actually ready, not the number bearing. The firing officer would have gun ready lights for those guns "ready" (loaded and bearing). Guns that were awaiting completion of the firing cycle or which were casualties would NOT be "o...

Re: More on KGV Class main armament problems

. Again I would point out that IF we are trying to get a "rate of fire" rather than just number of rounds fired over a period, then the first rounds should be ignored. With the first rounds the guns have been been loaded and aimed, only after those first rounds have been fired can the firing cycle s...

Well done Alberto for again demonstrating why your logic/arguments are so easily dismissed.

Please re-read your post and try to understand the failure.
