Other countries naval aviation during 1940


USA


The USN had been observing the use of air power by the Royal Navy with considerable interest (aided by the 'Canadian' observers on ships and the full reports they have been given). The main building plans include huge increases in the number of planes, and the building of the large Essex class carriers, however the first of these is not scheduled to be at sea before early 1943, although the possibility of speeding them up is being looked at, the proposed build times are already very short and the design is not yet complete.


In the meantime, the USA orders the construction of a fourth Yorktown-class fleet carrier, the USS Ticonderoga. The ship is laid down in March 1940 and given priority; it is expected to commission her in May 1942. After the fall of France and the corresponding increase in planned USN construction, the ship is given a maximum priority - it is hoped to have her complete by February 1942. The designers also hope to incorporate a heavier AA armament; they have noted that the Yorkdown class carry only 16 27mm cannon and 25 0.5" mg, compared to the British Formidable class carry 64 40mm and around 30 20mm cannon. The designers are told that the excellence of the USN's AA control makes the fitted guns far more effective than those fitted to Royal Navy ships, but this statement is controversial. When asked, the RN simply says 'the more guns the better'. As a compromise, 2 additional quad 27mm will be fitted.


The production of the Wildcat fighter has been speeded up, although at the moment many of the planes being produced are scheduled to be sold to the British and French. The USN is rather concerned that its frontline fighter, by no means in full operation in the fleet, is already outclassed in power and armament by the Goshawk (and the Goshawk engine is still being developed further). A new and much more powerful aircraft, the Vought F4U Corsair, flies for the first time in March 1940 (its development has been brought forward as much as was possible). The plane undergoes acceptance trials for the USN in late November of 1940.


Japan


Japan has also been following the success of the FAA with great interest, as it indicates to them that their intention of making naval aviation of major importance in the IJN is correct. Indeed, the aviation enthusiasts claim that this shows that all future resources should be aimed at carriers rather than battleships, a claim that is refuted completely by the battleships traditionalists in the IJN. In any case the current building program is full, with 6 fleet carriers expected to be available by late 1941.


However it is possible to increase the 'shadow carrier' program; these are large liners designed to be quickly converted into carriers. Two of these, the Hiyo and the Junyu were laid down in 1939 with completion expected in 1942. Two additional ships are laid down in March 1940, and it is hoped to have these too complete by 1942. While not as fast as fleet carriers, they do carry over 50 planes. A small expansion of the naval aviator training program is made to allow for the extra 100 pilots these carriers will need, although due to the extreme difficulty and length of the IJN training programs this target will in fact not be met.


Germany


The Graf Zeppelin completed her basic working up in October. Although the ship is classed as operation, her flight operations are still the subject of much experimentation (although some advice has been obtained from the Japanese). An air group has been assigned, and the carrier is continuing training in the Baltic, safe from the Royal Navy, along with the Bismark (who has also completed basic workup and is undergoing gunnery training while working with the GZ)


As a result of the success of the Royal Navy in naval air operations, the specialised anti-ship unit Fliegerkorps X has been given more resources. Founded in 1939, the formation has been in poor repute with the Kriegsmarine after the disastrous Operation Wikinger incident where the aircraft had sunk a German destroyer and caused a second one to be sunk in a minefield. However the obvious need to use aircraft to attack the Royal Navy has led to its rehabilitation after a more successful campaign in Norway. The unit will be transferred from Norway once it has been decided if it is best to deploy it in the North Sea or the Mediterranean - the current advice from the Kriegsmarine is in the Med. There is also a need to transfer additional planes; the unit currently consists mainly of Ju87 and Me109, and longer ranged aircraft are seen as necessary to attack the Royal Navy at sea. Priority is given for additional Ju87R, and Me110 (although this means reducing the daylight raids on England, this is actually seen as a bonus by the Luftwaffe due to the losses they are sustaining). He111 bombers are also being allocated. The support structure for the force is being moved to Sicily, and it is expected to be operational by the end of the year


Italy


While the Italian navy is slowly building an aircraft carrier, it is obvious that one carrier will simply be a fat target for the Royal Navy. Resources are therefore being given to building up the land-based attack capability, and looking at ways of arranging more and longer ranged fighter escort - the fighters defending the RN forces have showed that it is very difficult to arrange a good attack unless they can be suppressed or distracted, as even a few unopposed fighters can ruin an attack. The problem is the relatively backwardness of the Italian aviation industry. There is some pressure to license German engines, but the Germans want to charge licensing fees and there is considerable resistance to the idea itself inside Italy.

I know the Italians took a beating in OTL from the Royal Navy, but how many of these losses are OTL, and how many are a result of the British having better equipment and training this time around?
 
Well, the attack on Taranto is coming up. IOTl, the Italians had:

6 battleships
9 heavy cruisers
7 light cruisers
13 destroyers

and were attacked by 21 Swordfish in a single unescorted strike, with the second cancelled due to bad weather. They suffered 1 battleship destoyed and two damaged. A proportionally similar result, delivered by the aircraft from three fleet carriers with good enough weather for a second strike would seem likely to pretty much annihilate the Italian fleet, very likely sinking a greater tonnage of ships than the Japanese managed at Pearl Harbour with a significantly smaller deployment of forces. It could well be the most effective naval attack of all time.

I see no reason to reduce the effectiveness, night carrier strikes, particularly on ships in harbour were really an out of context problem for navies at the time, particularly for the Italians, who don't have operational radar.

If you were being particularly cruel you'd have the ATL Operation MB8 include a near simultaneous strike from Force H's aircraft carriers, escorting a Malta bound convoy as part of the deception, on the naval facilities at Naples, as that would massively add to the confusion about what was occuring.

That of course assumes that the Italians are caught as unawares as the KM was at Wilhelmshaven. ;)

During the OTL Taranto attack, the Italians knew full well the British were up to something, as they saw a British flying boat surveying the harbour in the afternoon prior to the attack - that's why they managed to fire nearly 14,000 shells from their AA batteries, including several thousand from their shipboard ones - they had their defences fully manned and alert.

Without radar, VT shells, or nightfighters, there was simply nothing they could do about it. Sortieing was against Italian naval doctrine and would just ensure that if they were caught there would be less AA defence, sunk ships couldn't be raised, and survivors couldn't be rescued.

I know I said many good things about IJN aviation, but their training programs were not what you would say "insightful" ... they keep the same system almost all of the war, while since Midway was completely overwhelmed and producing a derisory number or pilots.

The Marianas Turkey Shot did not happened just because after all. And of course after that they gave them a 4 hour tour of "How to crash your plane into the first ship you see (If you have enough fuel)"
 
10th October.


Although mass attacks are now only attempted by the Luftwaffe at night, there is a constant stream of small, high speed daytime attacks, by Me110 fighter-bombers are Ju88 bombers. These are difficult to intercept due to the high speed and the varied choice or targets (it is noted with some irony by the RAF that the Luftwaffe finally seem to be targeting the British aero industry). Even so, these daytime attacks are losing the Luftwaffe planes at the rate of more than 2:1 (and a far worse ratio of pilots) for little damage. As by now Britain is heavily outproducing the Luftwaffe in planes, the RAF is steadily increasing its strength relative to the Luftwaffe.


12th October


Earlier in the month a resupply convoy had been mounted from Alexandria. This had been escorted by the Implacable and Indefatigable, and the battleships Warspite and Valiant, as well as 6 cruisers and 16 destroyers; there was also a close escort force of two AA cruisers and four destroyers. Twelve Goshawks were successfully flown off on the 10th, and the convoy of four merchant ships arrived on the 11th. The Italian fleet had been prevented from intervening by poor weather. However on the 11th an Italian patrol aircraft spotted the ships returning from Malta. While this was happening, the cruiser HMS Ajax had been detached for a scouting mission (the poor weather was also affecting British air reconnaissance)


The Italian commander ordered a force of four destroyers to Cape Bon, in the chance the British ships were heading for Gibraltar (he judged that if they were in fact retiring to Alexandria that it would not be possible to intercept them). At the same time a force of four destroyers and three large torpedo boats were on patrol in the same area as Ajax.


At 0137 on the 12th Ajax was sighted by the three torpedo craft. They turned to engage (Ajax not having noticed them), and launched an attack with torpedoes and guns from a range of 1,900 yards. Ajax was hit three times, twice on the bridge and once below the waterline by 3.9" shells. The cruiser returned fire, hitting the Ariel (which would sink some 20 minutes later), and the Airone, left burning (she would sink some 2 hours later). The third craft, the Alcione, broke off contact.


Ajax resumed her course to the east, and at 0215 her radar detected two Italian destroyers. Aviere was hit by a surprise broadside, and forced to retire southwards. Artigliere managed to fire torpedoes and a number of salvoes before being hit by the cruiser and crippled. Ajax they engaged another destroyer, the Camicia Nera, but one of the hits from the Artigliere had disabled her radar, and at 0330 she broke off the action, short of ammunition.


The disabled Artigliere was taken in tow by the Camicia Nera, while the Aviere managed to withdraw under her own power. However although the damaged Ajax made her way back to the main body (she would require a month in dock to repair her damage), a strike was ordered from Implacable. 8 SeaLance and 16 Cormorant armed with 100lb bombs set off before dawn to intercept the fleeing Italian destroyers. The first ships spotted were the Camica Nera, still towing the Aviere, at 0730. Although the destroyers slipped her tow to try and evade the dive bombers, she was hit by two 1,000 pound bombs and sank within 15 minutes. The helpless Artigliere sank after a single bomb hit. Four of the Cormorants still had bombs, and the planes then carried on to search for the other damaged destroyer. She was sighted at 0815, and received the attentions of all 8 SeaLance and the remaining 4 Cormorants. Although she managed to avoid the dive bombing attack, in doing so she was hit by a torpedo, and left disabled and sinking (she sank some hours later after her crew had been taken off by another destroyer). No planes were lost to the destroyers AA fire.


While the daytime sinkings were not unexpected, the Italian Navy was very concerned at the efficiency the Royal Navy had shown in the night action; the use of starshells, searchlights and incendiary shells, plus the suspected use of radar, had completely outclassed the Italian night fighting skills.


14th October


The fleet returning to Alexandria is the subject of a number of attacks by the RA. These are driven off and disrupted by the carriers CAP; after months of experience the carriers and steadily increasing in their efficiency of managing and directing their fighters, although it appreciated there are still many improvements to be made. No ships are sunk or damaged, although the cruiser HMS Liverpool gets a nasty shock when a torpedo passes only yards from the ship; the torpedo plane had been attacked by goshawk and had launched just a little too soon before it was shot down.


18th October


The Japanese and authorities in the Dutch East Indies have discussions regarding oil supplies. It is agreed to supply 40% of production to the Japanese for the next six months. Attempts are made by the British to block this agreement.
In China, the first lorries to bring war supplies along the re-opened Burma Road - closed three months ago by agreement between Japan and Britain - arrived from Lashio. Drivers reported an uneventful journey free from the air attacks threatened by Japan against the Chinese section of the road.


Sixty lorries arrived in the first convoy and another 2,000 - given a banquet send off in Burma - are expected tomorrow. Waiting at Rangoon are another 500,000 tons of war supplies, including planes and munitions. On the return leg the lorries will carry tungsten, wood, tin, oil and pig bristles for export to the US.

Are you planing to devote a post to the Chinese pig bristle export industry?

Actually the attack plane stats are like this...

In OTL, the FAA used 17 attack planes (Swordfish), the other were carrying flares.
This time they have 120 attack aircraft. They may not need a second strike...:)
OTL got 3 hits from 13 planes (which is a bit more than the 1:6 usually planned for). This time they also have a heavier and more destructive torpedo.

As to a deception plan - why, I am shocked, SHOCKED I tell you to think that honorable gentlemen like the RN commanders would try and do something to decieve their noble Italian enemies....:eek::p:eek:

Well, if they are going to have two more carriers in 42 its reasonable to plan for pilots...howveer they wont actually manage to get them all trained in time - as you said, their training programs were very inflexible
 
Personally I think it deserves its own timeline....:p:D

Oh I quite agree. I am struggling to think of a believable POD though

The problem with the Chinese Pork Bristle Industry is that IOTL is a bit of a wank already. The usual suspects will rightly draw a fine tooth comb over the bristles and will be quick to cry wank if they see any evidence
 
This link has a very interesting assessment of Taranto. It includes the gem that the Italians didn't realise that torpedoes could be triggered by magnetic duplex pistols rather than on contact, so their torpedo netting could only protect against the latter. Even if the Italians had invested substantially more in anti-torpedo defences for the harbour after what happened to the Germans, it wouldn't make any difference.

On top of what I noted before, there are also sixteen submarines and nine tankers in harbour for the second strike.

The article is a nice examination of why Taranto was something of a missed opportunity, and demonstrates what more could have been done if more resources were available. An interesting one is the suggestion that the RAF was quite capable of bombing the harbour with Wellingtons the same night, (presumably guided in by the fires caused by the FAA's attack), as they made such an attack two days after the OTL Battle of Tanranto, allowing the FAA to concentrate on more valuable targets. After the beating the RAF has been getting about co-operation, I would think they would jump at the chance, and the more friendly aircraft there are over the city that night, the safer it is for everyone.

There is a lot to hit in Taranto though...

OTL got 3 hits from 13 planes (which is a bit more than the 1:6 usually planned for). This time they also have a heavier and more destructive torpedo.

The British achieved five torpedo hits (three on Littorio, one on Conte di Cavour, one on Ciao Duilio) out of the eleven they dropped.

On the other hand, out of the 60 bombs dropped, a quarter failed to explode. Have there been any drivers to resolve this? I don't recall any specific ones.

Perish the thought.

The RN bombs are a little better than the RAF average, simply because they recognise that with a relatively small number of planes and usually only one chance they need to do the maximum damage. Their failure rate is probably around 15%. It costs more to achieve this, but for the FAA its cost-effective. They also got early access to the better RDX-based fillings (again, more expensive, and they wont be with the RAF for another year or two).

The RAF will be involved, but its planned to have them over the Sicilian airfields at dawn...

The RN is prepared to risk the carriers to do more damage - Cunningham thnks that if he can deliver a significant enough blow it will scare the Italians so much they will be unwilling to venture out after. He quite correct :)

That's quite a substantial improvement. 25%->15%

They might do more good over Naples, but no big deal.

I do recommend reading through the link above then, there' some interesting thoughts on what they should have done.

If the full strike with 120 aircraft goes in, the question would be venture out with what?

The Italians have, at Taranto, according to the Fleet Air Arm Museum:

6 Battleships
7 Heavy cruisers
2 Light cruisers
28 Destroyers
5 Torpedo boats
16 Submarines
4 Minesweepers
1 Minelayer
9 Tankers
2 Hospital ships

That represents all the Italian Battleships, half their cruisers, and half their destroyers.

With a British attack of that magnitude, and the Italian inability to meaningfully defend themselves, they could all be destroyed over successive attacks. The British would need to launch a second strike though, and might even need to come back the next night.

A second strike might be practical.

A second night, that might be pushing it. Even if the Italians have no battleships left to send out, Italian submarines, and possibly even the odd U-boat, will be on the hunt, and daylight will bring every available Italian aircraft they can get up.
