This is the original design the 5 inch vessel in the "Burijas Request for Proposal" thread here was based on (though I made it slightly smaller to get the standard beneath 3000 tons though I still do not know what the deal is on that displacement issue).

8 - 1.97" / 50.0 mm guns (4x2 guns), 4.00lbs / 1.81kg shells, 1934 Model
Anti-aircraft guns in deck mounts
on side, all amidships
12 - 0.98" / 25.0 mm guns (4x3 guns), 0.57lbs / 0.26kg shells, 1934 Model
Anti-aircraft guns in deck mounts

Machine guns in deck mounts
on side, evenly spread
Weight of broadside 481 lbs / 218 kg
Shells per gun, main battery: 350
15 - 24.0" / 609.6 mm above water torpedoes
Armour:
- Gun armour: Face (max) Other gunhouse (avg) Barbette/hoist (max)
Main: 3.00" / 76 mm 1.00" / 25 mm 2.00" / 51 mm
2nd: 1.00" / 25 mm 1.00" / 25 mm -
3rd: 1.00" / 25 mm 1.00" / 25 mm -
4th: 0.50" / 13 mm 0.50" / 13 mm -
Machinery:
Oil fired boilers, steam turbines,
Geared drive, 2 shafts, 52,605 shp / 39,244 Kw = 34.50 kts
Range 7,700nm at 15.00 kts
Bunker at max displacement = 848 tons
Complement:
225 - 293
Cost:
£1.920 million / $7.679 million
Distribution of weights at normal displacement:

Miscellaneous weights: 330 tons, 9.5%
Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
1,054 lbs / 478 Kg = 16.9 x 5.0 " / 127 mm shells or 0.5 torpedoes

Roll period: 13.8 seconds
Steadiness - As gun platform (Average = 50 %): 70 %
- Recoil effect (Restricted arc if above 1.00): 0.42
Seaboat quality (Average = 1.00): 1.07
Hull form characteristics:
Hull has rise forward of midbreak
and transom stern
Block coefficient: 0.400
Length to Beam Ratio: 10.74 : 1
'Natural speed' for length: 25.00 kts
Power going to wave formation at top speed: 60 %
Trim (Max stability = 0, Max steadiness = 100): 65
Bow angle (Positive = bow angles forward): 30.00 degrees
Stern overhang: 1.00 ft / 0.30 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 26.00 ft / 7.92 m
- Forecastle (20%): 19.25 ft / 5.87 m

- Stern: 11.25 ft / 3.43 m
- Average freeboard: 16.59 ft / 5.06 m
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 161.1%
- Above water (accommodation/working, high = better): 63.8%
Waterplane Area: 13,281 Square feet or 1,234 Square metres

Wes, its shorter than an Akitsuki Class DD but squeezes in an extra bank of TT?
Cheers,

I think we had different rules back then, or maybe unqualified ones. Even so they're only 57tons over the 3000ton standard.

This design is longer than the Fletchers which had five single 5" mounts on the centerline and two banks of torpedos so I don't think her length should be a huge issue.

The rules never changed and it should still be light displacement. The only thing in Wesworld that was not determined by light displacement was the Cleito Treaty limitations.
