Remember that the tonnage figures in the editor are for "normal" displacement. The Brooklyns were 9800 tons normal and about 12000 tons full. I figure my Agano class adds another 2K. I still think you can build 3 *3 on 7000 standard (7700 normal)..the historical Aganos were not comparable with ships from other countries . Remember the Mogamis were 9000 standard than they added the bulges ( which don't add much to the cost) so if your getting to that range a CA is more useful and doesn't cost much more. This is from Springsharp using Ibuki style DP guns for secondary armament.

There will be no Katori class training cruisers. I will build these and probably another class of cruiser that I haven't figured out yet. The Aganos were just a good place to start. Here is what i used obviously before war refits. Upsized Yubari reuse 6.1" guns but with new 85 degree dual turrets ( layout and tonnage like Tromp). Actually good for 35 knots as i used actual machinery tonnage from a Japanese ship , and shp was quite a bit higher (Spring sharp doesn't have support for higher pressure boilers yet) Suzuka, Japan Light Cruiser laid down 1940 Displacement: 3,188 t light; 3,338 t standard; 3,641 t normal; 3,883 t full load Dimensions: Length (overall / waterline) x beam x draught (normal/deep) (454.79 ft / 439.63 ft) x 40.68 ft x (14.11 / 14.79 ft) (138.62 m / 134.00 m) x 12.40 m x (4.30 / 4.51 m) Armament: 6 - 6.10" / 155 mm 60.0 cal guns - 123.00lbs / 55.79kg shells, 150 per gun Breech loading guns in turret on barbette mounts, 1940 Model 3 x Twin mounts on centreline ends, majority forward 4 - 3.15" / 80.0 mm 60.0 cal guns - 13.21lbs / 5.99kg shells, 300 per gun Dual purpose guns in turret on barbette mounts, 1940 Model 2 x Twin mounts on sides, aft deck forward 12 - 0.98" / 25.0 mm 65.0 cal guns - 0.55lbs / 0.25kg shells, 2,000 per gun Anti-air guns in deck mounts, 1937 Model 4 x Triple mounts on sides, evenly spread 2 raised mounts Weight of broadside 797 lbs / 362 kg Main Torpedoes 8 - 24.0" / 610 mm, 23.79 ft / 7.25 m torpedoes - 2.040 t each, 16.319 t total In 4 sets of deck mounted carriage/fixed tubes Main DC/AS Mortars 2 - 220.46 lbs / 100.00 kg Depth Charges + 12 reloads - 1.378 t total in Stern depth charge racks Armour: - Belts: Width (max) Length (avg) Height (avg) Main: 1.38" / 35 mm 285.76 ft / 87.10 m 7.64 ft / 2.33 m Ends: 0.98" / 25 mm 153.84 ft / 46.89 m 7.64 ft / 2.33 m Main Belt covers 100% of normal length Main Belt inclined 20.00 degrees (positive = in) - Gun armour: Face (max) Other gunhouse (avg) Barbette/hoist (max) Main: 0.98" / 25 mm 0.98" / 25 mm 0.59" / 15 mm 2nd: 0.98" / 25 mm - 0.20" / 5 mm - Armoured deck - multiple decks: For and Aft decks: 1.97" / 50 mm Forecastle: 0.59" / 15 mm Quarter deck: 0.59" / 15 mm Machinery: Oil fired boilers, steam turbines, Geared drive, 2 shafts, 56,312 shp / 42,009 Kw = 33.99 kts Range 5,000nm at 14.00 kts Bunker at max displacement = 545 tons Complement: 233 - 304 Cost: £2.478 million / $9.913 million Distribution of weights at normal displacement: Armament: 274 tons, 7.5% - Guns: 252 tons, 6.9% - Weapons: 22 tons, 0.6% Armour: 607 tons, 16.7% - Belts: 166 tons, 4.6% - Armament: 44 tons, 1.2% - Armour Deck: 398 tons, 10.9% Machinery: 1,411 tons, 38.8% Hull, fittings & equipment: 880 tons, 24.2% Fuel, ammunition & stores: 453 tons, 12.4% Miscellaneous weights: 16 tons, 0.4% - Hull below water: 16 tons Overall survivability and seakeeping ability: Survivability (Non-critical penetrating hits needed to sink ship): 1,228 lbs / 557 Kg = 10.8 x 6.1 " / 155 mm shells or 0.3 torpedoes Stability (Unstable if below 1.00): 1.10 Metacentric height 1.5 ft / 0.5 m Roll period: 13.7 seconds Steadiness - As gun platform (Average = 50 %): 50 % - Recoil effect (Restricted arc if above 1.00): 0.62 Seaboat quality (Average = 1.00): 0.73 Hull form characteristics: Hull has raised forecastle, rise forward of midbreak, low quarterdeck , a straight bulbous bow and large transom stern Block coefficient (normal/deep): 0.505 / 0.514 Length to Beam Ratio: 10.81 : 1 'Natural speed' for length: 23.77 kts Power going to wave formation at top speed: 65 % Trim (Max stability = 0, Max steadiness = 100): 68 Bow angle (Positive = bow angles forward): 30.00 degrees Stern overhang: 0.00 ft / 0.00 m Freeboard (% = length of deck as a percentage of waterline length): Fore end, Aft end - Forecastle: 20.00%, 26.25 ft / 8.00 m, 20.34 ft / 6.20 m - Forward deck: 30.00%, 18.86 ft / 5.75 m, 18.86 ft / 5.75 m - Aft deck: 35.00%, 9.84 ft / 3.00 m, 9.84 ft / 3.00 m - Quarter deck: 15.00%, 9.45 ft / 2.88 m, 9.45 ft / 2.88 m - Average freeboard: 15.06 ft / 4.59 m Ship space, strength and comments: Space - Hull below water (magazines/engines, low = better): 151.7% - Above water (accommodation/working, high = better): 138.2% Waterplane Area: 12,450 Square feet or 1,157 Square metres Displacement factor (Displacement / loading): 79% Structure weight / hull surface area: 48 lbs/sq ft or 236 Kg/sq metre Hull strength (Relative): - Cross-sectional: 0.60 - Longitudinal: 0.99 - Overall: 0.63 Cramped machinery, storage, compartmentation space Excellent accommodation and workspace room Poor seaboat, wet and uncomfortable, reduced performance in heavy weather Good for 35 Knots
