In late 1935 the Commander in Chief China and Far East, Admiral Charles Morton Forbes, called for a new type of mini-destroyer to supplement the fleet destroyers and be built in large numbers at a low cost. The DNC asked his destroyer teams to come up with a small 600 ton design suitable for general escort and attacking roles. Admiral of the Fleet Roger Backhouse, Commander in Chief Home Fleet, also had similar ideas and he gave his full weight to the development of the 600 tons design. The first design had two single 4in guns for AA defence, multiple machine guns and a top speed of 32kts to match the latest cruisers and carriers it would escort. Range was kept at 2000nm at 12kts due to weight issues and the realisation they would not operate too far from a British base. Admiral Backhouse demanded two twin 4in mounts for AA defence of the fleet and speed had to be dropped to 30kts, he then decided that the planned 'Standard Type Destroyer' armed with single 4.7in or 4.5in guns would suffice and be better ships all round. Thus the new design became the 600 Ton Colonial Torpedo Boat focused on torpedo attack with a secondary escort function with a basic HACS. In effect these were modern S Class types, lightweight attacking ships rather than the heavy multi-purpose destroyers built since the Great War. Vice Admiral Andrew Cunningham, Commander in Chief Western Approaches, with extensive destroyer experience in the Mediterranean argued a single gun forward would suffice, the torpedo boat would have more need of a twin mount astern to cover the retreat and it was raised atop the deckhouse for better arcs and dryness. Seaworthiness was an important aspect in the design from the start. The weight saved by having a single 4in forward was used to provide a lightweight Asdic Type 141 intended for sloops and one depth-charge rack and two throwers. Torpedo armament remained three 21in tubes, 24.5in torpedoes being too heavy. The final designs featured a 0.661in multiple HMG mount amidships but this was altered to a quadruple 2pdr mount for the anti-MTB role and as an AA weapon. Two twin HMG mounts are also fitted.

Aircraft Carriers

Commander in Chief Fleet Air Aim Admiral R. G. H. Henderson at the end of 1935 decided which types he wanted to be built from 1936. The next five planned carriers were Carriers F, G, H, I and J.

The Swiftsure Class repeat with the new 4.5in and 57mm weapons had morphed, with the Sea Lords insistence on greater capacity, to a much larger ship. Some 800 feet long and 104 feet wide it was to carry around 96 aircraft and weighed some 10,000 tons more than HMS Swiftsure. The DNC was not satisfied with the cost and the resulting design was far larger than Admiral Henderson wanted. He had wanted armoured carriers and the DNC had overruled this, although the larger Swiftsure had 3in deck, 4.5in belt and 1.75in torpedo bulkhead armour. The design shrunk to 750 feet in length but still carried some 5000 tons of supplies, parts and fuel for its aircraft and was intended to be largely self-sufficient. The DNC then made further pruning of weights, but not armour, reduced the beam and got the design down to around 29,000 tons normal displacement. In this form the final design was approved by the DNC and Admiral Henderson as Carrier F (HMS Eagle) as the sixth fleet carrier to allow every major fleet to have two main carriers.

Carriers G, H, I and J could not be sister ships, the cost was too high. Admiral R. G. H. Henderson had been instrumental in the design of a class of new Trade Protection Carriers. These light carriers will be built to serve as carriers for the smaller Stations. In the event of a major war another eight of this class would be built as an Emergency War Standard Carrier. During 1936 the DNC and his main carrier designers worked on this proposal. The proposed 4in guns gave way to standard 4.5in twins, the new 57mm AA weapon was fitted but two octuple 2pr mounts were retained for anti-aircraft defence but also as anti-MTB guns. Belt armour was restricted to the magazines but calls for torpedo defence by the Sea Lords were abandoned as this added 2,000 tons to the ship and robbed internal space. The 3in armoured thick deck was reduced to 2in on the hangar deck to cover the vitals only. Splinter protection to the bridge was also sacrificed to save weight. 48 aircraft are to be carried in a single-storey hangar served by two lifts; the design can accommodate aircraft up to 15,000lbs in weight giving excellent growth characteristics.

Splinter protection to the bridge was also sacrificed to save weight. 48 aircraft are to be carried in a single-storey hangar served by two lifts; the design can accommodate aircraft up to 15,000lbs in weight giving excellent growth characteristics.

G-class looks solid, perhaps a little light on the 2-lbrs and a touch slower than I'd prefer, but on the smallish displacement a very solid design. The smallish displacement DOES allow for more to be built for the same cost.

The Coastal Torpedo Boat manages a better speed with better behavior than I've commonly seen in that size range, but only 3 torpedoes will make it's job difficult. The 30 knot speed is also a limitation, but it IS small.

HMS Eagle sounds not too different from the two German carriers being built in Nordmark, should be a powerful vessel.

The trade protection carriers sound like they're well-equipped with planes but pretty vulnerable to battle damage. However, that comes with the territory, so shouldn't be a surprise. Looking forward to seeing SS's of the carrier designs.

The Admiralty is now able to give specifications for Carriers F, G-J;

Regarding the Eagle...

9216t at least needed for the 96 planes, 250t for the 10 spare planes, something like 200-300t for the other gear (at least). Total needed would be at least 9700 tons but you only have 7000 tons assigned to the miscellaneous weights. That's good for a maximum of 83 planes without anything else.

Also the maximum this carrier can carry is 94.75 planes so it is not even possible to "usually carry" 96 planes. (750x94.75)/750 = 94.75 planes.

Planes are Barracudas and Gloster F.5/34 Gannets?

Yes the aircraft are Gloster Gannets and Fairey Barracudas with a Vickers-Supermarine Sea Otter.

No doubt the small carrier will lend itself to export versions (to the right allies)

Well it's not a final design, just seeing where things are going, originally it had a 104 foot beam, probably 72 aircraft will be enough anyway for RN doctrine, I don't really want to build a carrier nearer 35,000 tons. The idea mainly is to improve self-suffiency over the Swiftsure Class until a carrier tender enters service rather than airgroup power. Its clear I've underestiamted weights somewhere...

Most likely the problem was forgetting that aircraft tonnage is the square of the number of aircraft, or number of aircraft * 25, whichever is greater. That's gotten me a few times. Still a powerful vessel, just not quite as powerful as previously thought.

I do have one question: why no transom stern?

After consulting with his German counterpart the DNC draws up yet another design, this time with some misc weght reduced and put towards another 1in thick armoured deck below the main armour deck as a splinter barrier.

Heh, the German designers spent a lot of time consulting with others more experienced than themselves on carrier construction before they tried to design their own.

This one's solid: the extra splinter barrier's no bad thing, the smaller size will make her cheaper to produce, and there's not so much unused tonnage.

Why was Henderson overruled with regards to armoured carrier development? With the increased threat level in WW, the argument for an armoured carrier with enclosed hangar makes even more sense.

The figures for the TPC are hugely optimistic compared to the RN's own studies;

Armour notes;

Designs f and J had 2.5in NC steel flight deck covering full width of Flight deck and 400/480ft respectively in length (covering full hangers in both and then extending aft beyond). Both had 2in forward bulkhead. For an extra 600 tons design J could have a 3in flightdeck. All NC.

For F and J Belt 4.5in C armour covering Mags and machinery which ran from HD to 3.5 ft below waterline. Reducing this belt to 3in would save 220 tons and £45000.

Design G had similar protection to Ark Royal with 3.5 in belt.

The armoured carrier is a curious thing. If you believe the carrier is a floating airbase then it makes sense to protect it. The question is which is better at keeping a carrier operational, one with 4in thick flight decks with a handful of fighters and strike aircraft or one that can carry 30-40 fighters for self-protection and another 20-40 strike aircraft? Armour is passive, it costs weight and only is useful in defence, better to spend the weight in aircraft which can shoot down enemy bombers and bombers which can cripple the enemy. Ilustrious et al were good at absorbing damage but so were the Essex Class, yet they only had 30 or so aircraft (the Implacables carried more but their airgroups were still were dwarfed by most other carriers of similar size).

Only one carrier is desired so it makes sense not to introduce a totally new type of carrier. The next two tentative carriers for 1939 might be armoured carriers of some form.

The TPC is not an armoured carrier, it is a Colossus clone with some deck armour over the engines and magazines and box armour around the magazines. Still the figures you quote amply show the limitations of armoured carriers...

The point is more that the specs you can get in SS are massively more than what was acheived in practice. For a simple Colossus clone she's massively more capable.

I agree with regards to aircraft development. Another argument for larger carriers. My favourite is simply "Small Ships Sink Soon"

I like the choice of AA weapons on the carriers.

The real UK did have 57mm QF guns (aka 6pdr's) and 40mm's (aka 2pdr's).

Which brings up a slightly OT question -

If a country refers to it's armament by pounds (2 pdr's, etc) how can that be shown in springsharp?

There was a difference in the 2pdr vs. the 40mm.

The UK used 2pdr pom-poms which weren't exactly the same in weight/performance as a comparable 40mm multi barrel mount.

Refit Changes 1935:

Replacement of casemates with ten twin 4.5in DP mounts

Six twin 6pdr AA mounts (two on quarterdeck, rest on after superstructure)

Four octuple 2pdr AA fitted

Four sextuple MG mounts fitted (two on bridge and one on each B and X turret)

Two new main directors and four new HACS fitted

Type 281 and Type 79 RDF fitted

New 15in external belt

Removal of end belts

Extra 1.5in torpedo bulkhead fitted inside new bulge

Extra 1in added to main deck armour and new 1.5in burster deack added along full length of ship

New bows fitted

New boilers and turbines fitted, speed increased to 27kts

Extra bunkerage fitted inside bulges

Also the shocking poor state of the AA defences of the Resolution Class will be addressed by a 5% refit which will add two 2pdr octuple mounts and four .661in HMG sextuple mounts. The existing HA fire control system will be used, HACS will not be installed as the remaining lifespan of the class does not justify the costs.

The plan to build the 600 Ton Colonial boat has been put back as the First Sea Lord felt the submarine situation had to be improved in order to retire older Great War era boats still in service.

The DNC and his submarine team has modernised the P Class design with a stronger and larger hull for increased range and a more potent 4in gun for anti-merchant shelling. Many older officers have objected to the U name and pennents but the Admiralty has insisted on the numbers. No rear tube was fitted owing to the single shaft design and the lack of space in the stern. Tactically it is not thought to pose a serious problem. At least two flotillas (10 boats) will be built this year.
