On April 9 1942 9 Blenheims bombed the KB, and four were shot down by CAP, near the carriers, for the loss of one Zero, but unluckily the Blenheims were intercepted a 2nd time by Zeros and Vals returning from the Hermes strike, and another Blenheim and a Zero were shot down. So the KB, with 5 carriers and ~20 Zeros aloft only managed to shoot down 4 Blenheims. If we add ~30 Fairey Battles to the Blenheim formation, it seems unlikely that RAF losses would increase much since the Battle has the same (IIRC) defensive armament as a Blenheim and similar top speed. Ditto for a squadron or two of Skuas, albeit slower than Blenheims.
Yes, but after they dropped their bombs over the targets. Their mission was complete.So the KB, with 5 carriers and ~20 Zeros aloft only managed to shoot down 4 Blenheims.
The Aug 7 strike flew from Rabaul and ditched near Shortland Island.To clarify, I looked back into my bookshelves and found that I misremembered this. The Type 99s that struck the 'Canal sortied from Buin and not Rabaul -- a much shorter flight.
Or SBDs?I am very well aware of that (in certain circles) very famous Blenheim mission, during which I think the Blenheim crews got very very lucky to get as far as they did, which in terms of actual damage to the Japanese fleet, was not very far at all. I know this mission has assumed nigh heroic stature among some folks, I just do not perceive it the same way.
In fact I do not even come close to your rosy estimate for the survival rate of Battles, Blenheims, Skuas, Vindicators or any other such obsolete aircraft against the Japanese fleet. In fact next to Battles Blenheims look like F-16s, but they were still nowhere near up to the task. But the truth is we will never know.
I base this opinion on two things:
1) The ratio of losses to the rest of the British forces during that very same battle, of which the dismal performance by the Blenheims was the stand out success, and
2) The catastrophic loss rates and even more dismal results by Blenheims during various operations in the Burma and in Malaya.
I'd say the overall outlook is pretty grim unless you get better fighters and / or a lot more of them, and better bombers too.
Or maybe attack with Wellingtons at night
Or SBDs?
The losses against Zero escorts were not as severe as it seems, as many Hurricanes were caught during TO on April 5.
There's quite a difference in the tactical situation for Zero's flying carrier CAP and land based fighters. The CAP fighters are constrained in their ability to chase targets too far away from the carriers that they are tasked to protect, and historically, if the IJNAF didn't intercept prior to the Allied strike their effectiveness was greatly reduced.
It's unfortunate that the Blenheims used a level bombing attack, rather than low level glide bombing.
A couple of points.
The last time the SBD participated in a carrier battle was at Philippine Sea in June 1944. And even then it was only aboard three CV and they were replaced by the SB2C between July & Sept. The SB2C was first used operationally against Rabaul in Nov 1943. After June 1944 the SBD was only being used operationally by the USMC from land bases.
The range of the Swordfish when it was designed, and for how and where the RN expected to be fighting was perfectly adequate. For example the distance from Libya to Crete at its narrowest is about 200 miles. Malta to Sicily just 60 miles. At Taranto, with the extra fuel tank in the Observer's cockpit or slung under the belly and without the TAG, were launched 170 miles from the target.
When it comes to the Pacific, I think many have an exaggerated idea of the operating ranges. As a generality the IJN sought to outrange the USN by 25-50 miles.
There is a need to distinguish between search missions with aircraft being sent out with no, or at least reduced, bomb loads and filled with as much fuel as possible, and strike missions. Generally the USN was looking at strike ranges of about 200 miles against an enemy fleet. But distances would generally be shorter in support of amphibious operations. But all sorts of things could be changed to suit operational conditions. Philippine Sea is an oddity because of a variety of factors.
For both sides, much depended on how good the search was to locate and report the other side first.
At Philippine Sea on 19th June 1944 the IJN launched from 280-400 miles because their forces were so spread out and because their aircraft were planning to land on Saipan after the strike rather than return to their carriers.
On the 20th the USN sent a search group out to over 325 miles in the afternoon which was considered an extreme range. When the strike was planned there were a number of reports with positions that contained a variety of positions and distances. They started at 275 miles before pushing out to 300 and on to 330 miles. Then figure in the relative speeds of the two fleets and the fact that the wind was blowing in exactly the opposite direction to that which TF58 needed for launch & recovery. The return journey was estimated at 250 miles due to the carriers closing the distance at about 22 knots during the 4 hours between the completion of launch and the start of recovery. The whole recovery cycle took about 2 hours in the dark with many pilots having very little night flying experience.
But there were sacrifices to achieve that long range. The air groups formed up en route instead of overhead each carrier group, as was the normal practice, in order to save fuel. Just make matters worse on arrival over the targets time was tight as the sun was going down. So there was not time for attacks to be co-ordinated. The result? About 80 aircraft lost from fuel shortages compared to 20 over the targets out of 226 that departed.
So basically the pilots had range anxiety throughout the mission.
On 16th Feb 1945 TF58 launched against the Tokyo area from just 60 miles off the coast of Japan. On 19th March, Franklin was hit when about 50 miles offshore when the target was Kure & Kobe (OK they had to fly over Shikoku to reach those targets on the Inland Sea so the distance to the target was greater). In July / Aug British and USN carrier aircraft were able to roam over most of both Japanese coasts as the carriers repositioned up and down the coast between strike periods.
HiI actually hadn't seen that post yet, as it appeared while I was writing the one above yours, which you apparently read but ignored?
But as I noted, while mast-head bombing was feasible against merchant shipping (with little or no AAA and usually no fighter defense), it was a lot riskier against warships. Especially larger warships and groups of warships with larger ones in the mix.
I haven't read all the stuff Mike posted yet (looks very interesting!) but a quick look suggests this is indeed about attacking merchant shipping. The photo shows a small cargo ship under attack. Planes like FW 200 Condors and Vickers Wellingtons could and did sink little isolated cargo steamers that way, but that's not what we are talking about here, is it?
Hi
Why do you think the mast-head attacks illustrated were against targets "with little or no AAA and usually no fighter defense". These attacks were made against German coastal convoys off the Norwegian, France and the low countries coasts, very near to Luftwaffe airfields, which is why 'surprise' was considered important, they wanted to start hitting the ships before the Luftwaffe turned up. Below are a couple of maps (from 'A Forgotten Offensive' by Christina Goulter):

From the same source mention of the increasing protection for these convoys:

Lots of Flak to contend with. From 1941 there were increasing amount of escorts used, indeed outnumbering the cargo ships at times. Example below showing attack on German convoy off the Dutch close on 20 November 1942 (from 'The Strike Wings' by Roy Conyers Nesbit):

This is just to point out the RAF was not picking off isolated ships that had poor defensive capabilities, it was a very dangerous occupation. It would have been nice to have a Beaufighter equipped Strike Wing plus lots more fighters out in Ceylon, but it was too early in the war to be able to do that and would still have been costly unless there were enough allied aircraft to overwhelm the Japanese carrier force air element, that would need a lot of aircraft not a few obsolete types.

Hell yeah! I never met him but I worked with his daughter while on the railroad. She was one smart CPO (RET).And Gabby Gabreski on bass guitar!
Swordfish pilots would have a hell of a lot of anxiety trying to fly a 250 mile mission...
There was nothing wrong with Japanese scientists. They were after all the first to develop the magnetron which was the key to centimetric radar. Neither service did anything much with radar tech until they started getting hold of allied sets in places like Malaya & Singapore. But those were early metric wavelength radars.Indeed. If there was on thing the Japanese should have acquired from their German allies it's radar tech. Imagine at Coral Sea and Midway (first tested and then perfected after this Ceylon raid) if Nagumo's carriers had air-intercept (air-warning) radar. By 1939, the Germans had installed surface-search and gunnery radars, not air-intercept onto the Scharnhorst class battleships, which could have been installed as an air-warning set in at least one IJN carrier (along with a CIC or FDO and working radios) by 1942. If Nagumo has radar, my Skuas and Chesapeakes, along with the Blenheims will not find those essential undefended skies that day.
But as I noted given the intended operating areas, the Swordfish had enough range. This seems to something those from the USA have trouble getting their heads around. The RN never intended to go to the Pacific. Any fighting in the Far East was expected to be in the South China Sea.When it was designed? Sure, you could argue that, but that was what, 1933? The truth is the Swordfish had barely more than half the range of a D3A or SBD.
SBDs and F4Fs had a much closer max range to IJN equivalents than Swordfish and Hurricanes though, let's be real. I don't think that is a really valid comparison.
IJN could outrange the Swordfish by at least 100 miles, with plenty of margin for error.

But the RN trained from pre-war to use its TB to attack at night or in bad weather, something they did successfully from the earliest days of the war. They recognised the limitations of the aircraft they had worked to minimise the risks. Only in extreme circumstances were they forced into attacking in daylight against modern fighters (Channel Dash or Kirkenes)No matter how you fold, re-analyze, or spin it, Swordfish had by far the least effective range of any Axis or Allied naval strike aircraft active in 1945, or 1944 or 1943 for that matter.
The only one it surpasses is the miserable Douglas Devastator, which was of similar vintage.
Yes, but...Indeed. If there was on thing the Japanese should have acquired from their German allies it's radar tech.

When was the first USN night attack? Oh yes Feb 1944 at Truk using 12 Avengers.
I agree that in the OTL rapid reinforcement of Ceylon is unlikely but I also think that it wouldn't have taken a very large departure from the OTL to have built more airbases on Ceylon and established OTU squadrons there with a couple of Battle and/or Skua squadrons.I don't see how Lease/Lend DB, or Skuas, get to Ceylon--I am going to have to accept the contrarian rôle on thay count--but I will agree that if it is a half dozen true Dive Bombers with competent crews and armed with 1,000 lbs. bombs, then the Japanese carriers of the First and Second Squadrons (Akagi, Soryu, & Hiryu) are extremely vulnerable, the two of the Fifth Squadron (Shokaku & Zuikaku) less so, but still liable to serious damage.
There was a better chance of Sommerville launching his Swordfish night torpedo attack--far fewer "ifs" have to swing the British way. What might have happened the next morning is another tale, of course. It seemes unlikely the Swordfish could have knocked out all the Japanese carriers, and it is always possible they wouldn't have even hit one.

Yet the USN used the TBD until Midway... at least with Swordfish they could have used a night TB strike. In mid 1942 Nimitz was calling for Merlin engined fighters to be placed on USN carriers...:Those Americans were clearly fools not to re-equip all of their navy squadrons with Swordfish and Sea-Hurricanes! I suspect this may have been only the latest by that time in a long series of dreadful mistakes they kept making, and might have been talked out of had they only been willing to listen.
