One problem with mirroring to closely to what was done in history up through early WWI is that up to that point the differences in systems between obsolete units resigned to training commands (or even captured units assigned to training commands) and front line units was usually a fairly small matter of degree. The gun caliber might be bigger; you might have guns in turrets instead of casements, but most of the equipment and actions were pretty similar. There were still some differences (in things like fire control and range-finding; but you had a very limited number of sailors who needed technical training to handle those).marklbailey wrote:That also gives this fictional Admiralty exactly the problem the real one had with Dominion naval forces, how to ensure training to common standards? Within the British Empire that was done by mutually agreed standards, adoption of RN training systems and standards etc. That will not work easily on the sort of scale involved in this fictional universe. it will have to be 'tiered' especially at lower skill/education levels.
This is precisely where a standardised class of TS inexpensive enough for each 'nation' to own and operate directly is required. It enables the upper end of a remedial training system to be standardised. That forms a 'gateway' in terms of standards. In this case, that 'gateway' will be the minimum standard required for remedially trained personnel to be employable in basic roles aboard Imperial Navy ships to Imperial Naval standards. That means they can start cycles of Imperial service - back to their own Navy to raise their standards. This is all common 'train the trainers' stuff, I might add. The Romans did stuff like this.
Once you move into late WWI, and accelerating through WWII the differences become much much larger; and dominated first by the evolving engineering systems, then by the rapidly proliferating and growing complexity of their combat systems. Oil firing vs coal; or later diesel or nuclear or gas turbine; Sonar, Radar, digitized versions of each, computerized signal processing of each; unified plotting, data link, sensor fusion; steady evolution of missiles and guided weapons of various sorts and their control hardware, etc, etc, etc.
Training sailors on the specific combat systems became a major hurdle; enough so that it took significant retraining to move them between ship classes within the same navy that had different combat system architectures.
Training the Talbott Quadrant SDFs on captured SLN navy equipment gives them a relatively minor leg up once you want to transition them to first0 (or even second- or third-) line RMN equipment. The design and interfaces of most of the combat systems are just too different; so the training of how to perform maintenance or operations on old SLN stuff doesn't really bridge over to RMN stuff. Its only (IMHO) worth doing if you're going to keep the Talbott SDFs on ex-SLN 4th tier stuff for at least a generation (15-20 years). Otherwise it's just a waste of time; you'd be better off doing groundside training in simulators for how to handle, maintain, and repair RMN combat systems.
