The Naval Staff has issued an Operational -Tactical Requirement (OTR) for a light aircraft carrier. The OTR has been sent to the Naval Constructors Board and the Scientific-Technical Research Committee. A pre-design sketch by a Project Design Team has been evaluated by the Naval Constructors Board and Scientific-Technical Research Committee. A Technical-Tactical Requirement (TTR) has now been released to external companies. The home-grown design is the Project 702 (marked Top Secret and not available to view). An export design is to be designated Project 703.

Desired Specifications

Size: preferably no longer than 170m but up to 200m considered. 170m perferred for home construction.
Displacement: No greater than 16,000 tons normal
Speed: 30kts minimum and 32kts preferred
Range: 8000-1000 miles @ 15kts
Armament: Must be armed with the 115mm DP gun (25.00kg shell) with turret (50/25/30mm armour). 130 and 100mm guns might be considered. Must have at least four quad 37mm and four sextuple 20mm mounts and others as singles
Air Group: Must carry 36 aircraft, space for 40 preferred for growth
Hangar Height: Must be 18 ft (5.5m) high, single or doubel-decker hangars considered
Armour: Light but able to resist destroyer fire, belt and deck (hangar floor) armour required and torpedo protection if possible.

If all designs prove unaccpetable a new Technical - Tactical Requirement will be issued.

Australia offers the following design based on HMAS Enterprise.

Edit: fixed turret armor, reduced range to 10knm, reduced to under 16000n,

The design meets or exceeds all specifications.

In order to meet the preferences of the client, a relatively low L:B ratio and high BC was chosen, allowing for a somewhat roomier hanger.

Gun battery includes 4 turrets fore/aft of the island. An additional 8 deck mounts are mounted at the corners of the flight deck, like the OTL Yorktowns.
The 20mm and 37mm mount alternate along the edge of the flight deck.

Aircraft capacity is 48 planes, which allows the 40 plus spares
2304 misc weight allocated
SQRT (2304) = 48
LxB = 170mx24.5m = 4165 /70 = 59.5

High freeboard is to represent an enclosed Hanger. This choice was made due to potential operations in the extreme south, including the straits of Magellen. It is anticipated the main armor belt extends 1m above the waterline to the armor deck, above which is a full 2.44m deck, and then the 5.5m hanger.

The 3.66m aft overhang represents the aft round-down, giving a 175m / 574 ft. flight deck. Two large centerline lifts are provided.

An extra 100 misc weight represents additional ventilation and fire fighting equipment.
100 tons misc is "spare" for domestic equipment. .

Misc: 1800 tons= 40 AC

Observation : SQRT(1600) = 40. The design has plenty of excess comp hull and misc weight.
But..
Question- I count 32 (?) below decks, and no room to maneuver them, service them, etc. Basically the 6 near the one elevator*must* be the first moved on deck, and you have to have a deck park just to carry your max capacity.

Carry 40, sure. But with that 2/3s length hanger, operate 40? Perhaps in wartime, but in peace, in the early 30s, do you want your 20%+ of your aircraft exposed to the elements 24/7 ?

Italy offers the following design. The single hangar is 140m x 18m and protected by 40mm splinter paltes on the sides. A large accelerator is mounted forwards neccestating the shift of the elevator to the starboard side. Maximum airgroup with a deck park is 60 aircraft but there is hangar space for about 40 (which is all that could be reasonably operated.)

Wes, top and side view not fit on your drawing (see deck edge platforms for example)....?!

Its a rough representation, based on the CVT Nautica.

Deadline for submisisons is 12:00pm GMT Friday 2nd March.

Not bad so far but could a couple more 170m designs be submitted as these would meet the specification more closely. Any ships over that will have to be built abroad, and none could be built in a home yard for some time. Politics is not a factor in selection.

557ft version, has extra strength for further improvements.

Ansaldo - Italia feels that 170m is too short a hull length to be of sufficient use as an aircraft carrier and will not be resubmitting a tender.

Walter, I'd sure love to see that carriers drawing, seems rather cramped.

Chile will not enter this contest due to the only designs on Chilean drawing boards are much longer than 170 meters, and our existing carrier is of Atlantean design.

Also we wouldn't want to loose an edge however small it actually is now would we.

What the heck; call this a private sector entry from Naval Defence Solutions Inc.

All weapons are mounted on the sides, while exhaust is trunked aft and discharged downward, similar to the historical Kaga. Together, this allows for a small island and an otherwise unobstructed flight deck, an important consideration given the relative restricted size of the deck.

Lighter weapons are simmed as enclosed mountings, to protect crews from exhaust gases and weather.

Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
30,806 lbs / 13,974 Kg = 663.9 x 4.5 " / 115 mm shells or 7.6 torpedoes
Stability (Unstable if below 1.00): 1.16
Metacentric height 7.1 ft / 2.2 m
Roll period: 16.6 seconds
Steadiness - As gun platform (Average = 50 %): 81 %
- Recoil effect (Restricted arc if above 1.00): 0.01
Seaboat quality (Average = 1.00): 0.81

Hull form characteristics:
Hull has a flush deck
Block coefficient: 0.416
Length to Beam Ratio: 5.31 : 1
'Natural speed' for length: 23.62 kts
Power going to wave formation at top speed: 60 %
Trim (Max stability = 0, Max steadiness = 100): 100
Bow angle (Positive = bow angles forward): 0.00 degrees
Stern overhang: 0.00 ft / 0.00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 25.98 ft / 7.92 m
- Forecastle (20 %): 16.54 ft / 5.04 m
- Mid (50 %): 16.54 ft / 5.04 m
- Quarterdeck (15 %): 16.54 ft / 5.04 m
- Stern: 16.54 ft / 5.04 m
- Average freeboard: 17.29 ft / 5.27 m

Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 71.6 %
- Above water (accommodation/working, high = better): 161.5 %
Waterplane Area: 36,416 Square feet or 3,383 Square metres
Displacement factor (Displacement / loading): 239 %
Structure weight / hull surface area: 221 lbs/sq ft or 1,079 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 1.90
- Longitudinal: 2.75
- Overall: 1.97
Hull space for machinery, storage, compartmentation is excellent
Room for accommodation and workspaces is excellent
Ship has slow, easy roll, a good, steady gun platform
Poor seaboat, wet and uncomfortable, reduced performance in heavy weather

3 Elevators, 100,000 sq ft of aircraft storage space split evenly on 2 Hanger decks 50,000 sqft per deck. Design calls for a complement of 60 (180,000 lbs) aircraft 30 stored on each hanger deck

Unless i totaly blew it on the math belive it or not it works lol actualy room for more / larger planes than the ones i used. Aircraft info is based off the p26 peashooter which was in production in 1932
