This is the chart of specifics i told you:
- Battleship: 12-16" gun, 45k ton limit
- Battlecruiser: 12-14" gun, 35k ton limit
- Heavy cruiser: 6-9.2" gun, 15k ton limit
- Light cruiser: 4-6" gun, 7k ton limit
- Destroyer: 3-5" gun, 5k ton limit.
It's sketchy, but is a start, i had other chart around but can't remember where i left it.
Principal opinion of the Author requested please
Several issues there.
I can't see anyone going for separate limits for battleships and battlecruisers - the term 'capital ship' was coined pre-war. Any treaty would need comprehensive inspection to enforce such a difference.
As you and many others have been discussing, it's very difficult to define what a cruiser is - anything from a 4,000t ship with a few 4.7" guns, up to a 20,000t ship with 12".
With such a wide variation, it's going to be tough to agree limits... ratios of types, tonnages, numbers of ships, total tonnage ... there are many options.
5,000 tons is too high for a 1920s destroyer. Most were under 1,300 at the time, with even the largest leaders at about 2,000.
