The Laooland aircraftcarrier

This is swedens first aircraftcarrier(and my first carrier design aswell)

Originally laid down as 35000 ton BB converted on the stocks to a CV.

How many aircraft can she accomodate? How large planes? (I was thinking of Hawker Harts and Gloster Gladiators)

Lappland, Sweden Aircraftcarrier laid down 1932

Displacement:
31 913 t light; 32 658 t standard; 35 000 t normal; 36 733 t full load
Loading submergence 1 516 tons/feet

Dimensions:
656,17 ft x 104,99 ft x 26,25 ft (normal load)
200,00 m x 32,00 m x 8,00 m

Armament:
12 - 4,13" / 105 mm guns
20 - 2,24" / 57 mm guns
20 - 0,98" / 25 mm AA guns
Weight of broadside 546 lbs / 248 kg

Armour:
Belt 5,91" / 150 mm, ends unarmoured
Belts cover 120 % of normal area
Main gun shields 2,95" / 75 mm, 2nd gun shields 0,39" / 10 mm
Armour deck 0,98" / 25 mm, Conning tower 5,91" / 150 mm

Machinery:
Oil fired boilers, steam turbines,
Geared drive, 4 shafts, 159 412 shp / 118 921 Kw = 30,00 kts
Range 10 000nm at 14,00 kts

Complement:
1 279 - 1 663

Cost:
£8,332 million / $33,328 million

Distribution of weights at normal displacement:
Armament: 68 tons, 0,2 %
Armour: 2 812 tons, 8,0 %
Belts: 1 612 tons, 4,6 %, Armament: 97 tons, 0,3 %, Armour Deck: 966 tons, 2,8 %
Conning Tower: 137 tons, 0,4 %, Torpedo bulkhead: 0 tons, 0,0 %
Machinery: 4 705 tons, 13,4 %
Hull, fittings & equipment: 14 328 tons, 40,9 %
Fuel, ammunition & stores: 3 087 tons, 8,8 %
Miscellaneous weights: 10 000 tons, 28,6 %

Metacentric height 5,7

Remarks:
Hull space for machinery, storage & compartmentation is excellent
Room for accommodation & workspaces is excellent
Ship has slow, easy roll, a good, steady gun platform
Excellent seaboat, comfortable and able to fight her guns in the heaviest weather

Estimated overall survivability and seakeeping ability:
Relative margin of stability: 1,03
Shellfire needed to sink: 62 452 lbs / 28 328 Kg = 1 768,1 x 4,1 " / 105 mm shells
(Approx weight of penetrating shell hits needed to sink ship excluding critical hits)
Torpedoes needed to sink: 4,3
(Approx number of typical torpedo hits needed to sink ship)
Relative steadiness as gun platform: 83 %
(Average = 50 %)
Relative rocking effect from firing to beam: 0,02
Relative quality as seaboat: 1,66

Hull form characteristics:
Block coefficient: 0,678
Sharpness coefficient: 0,45
Hull speed coefficient 'M': 6,14
'Natural speed' for length: 25,62 kts
Power going to wave formation at top speed: 61 %
Trim: 50
(Maximise stabilty/flotation = 0, Maximise steadiness/seakeeping = 100)

Estimated hull characteristics & strength:
Underwater volume absorbed by magazines and engineering spaces: 76,9 %
Relative accommodation and working space: 311,2 %
(Average = 100%)
Displacement factor: 154 %
(Displacement relative to loading factors)
Relative cross-sectional hull strength: 1,20
(Structure weight / hull surface area: 178 lbs / square foot or 867 Kg / square metre)
Relative longitudinal hull strength: 3,45
(for 39,37 ft / 12,00 m average freeboard, freeboard adjustment 19,92 ft)
Relative composite hull strength: 1,34

Well, when looking at the springstyle notes, 10,000 tons of miscellaneous load will give you 100 planes. When looking at the dimensions, you'll get (656.17x104.99)/750=91.86 planes. The ships carried by the carrier is the lower of the two numbers thus 91.
... but how big the planes can be in reality is a good question. Looking at the size of the CV, it would not be a good idea to use planes the size of an F-14. Looking at the dimensions of the Hart and the Gladiator, I think 91 planes might just fit... although it is also possible that all 91 might not fit at all.

Size

IIRC, the rules to design a CV with springstyle speak of planes of WW2 vintage. Thus a F-14 surely is too big (that one´s even larger and heavier than a B-25) but a Gloster Gladiator seems to fit quite good.

Just my ille-informed opinion of course... :)

A pic of her

I have uploaded a picture and some extra facts about her on my homepage.

The Uppland Heavy cruiser is also new

comments please

This typo occurs on your Uppland-class page;
Displacement 1000t, surely this should be 10,000t.

It is a nice picture, but the forward superstructure seems a bit small.
