I would suggest that part of the Thunderbolt's success in crossbow was because many Jug pilots were in fact ground attack specialists and had experience hitting small targets like tanks in support of the GIs. They (9th AF Jug groups) also had experience in flying weaving and jinking attack runs to throw off the flak gunners and still deliver the ordinance on target. 8th AF Jug groups were not ground support specialists and had lower kill counts and higher losses on such missions.

@@alangledhill6454 Harris said the same thing, but when directed against oil targets, accuracy was very good. The issue with Crossbow is that low level attacks against targets hidden in woodland were chosen, often night raids, and that was a pretty impossible task. The idea that BC only trained for only area raids is inaccurate, though, as from 1942, attacks against point targets were carried out at night against larger factories or factory complexes. When the target area was a city, then success criteria were set relative to that which can give an incorrect impression of achievable accuracy. In reality, even area attacks were often only on part of larger cities. But you are correct, apart from 617, there wasn't much standard training for missions at 1000ft. Given the numbers involved (200 was typical) I don't think training in low level operations was given.

[@shero113]

There was a specialist Lancaster unit, 617, who had amazing accuracy, hitting the Turpitz, Operation Chastise (of course!), and the V3, as well as railway tunnels. The point is, properly trained, crews can do amazing things. However, hitting 'ski ramps' from 20k feet, is still very difficult. The Upkeep bomb was released at 240 feet (IIRC). The Mosquitos though specialised in high accuracy raids, such as Amiens, and other specific buildings. Interestingly, when it was used like a B-17 (q.v. other video) as the RAF did initially, it was a failure, but as what today we'd call a strike aircraft - fast, low level, accurate - it was probably the best of WWII, although the P-38 might be good here too?

[@jackgee3200]

4:57 Not the ramp shape. 'Ski' sites because of the aerial view shape of the launch support buildings, labelled 'S' - observed by photo-recon interpreters ("like a ski on its side") when the V1 system was still in development. This was ~ the first definitive identifying feature of this weapon system as the ramps were extremely hard to spot/identify at that stage - or even later when known about, unless low angle illumination caused a long shadow.

[@davidpf043]

The V-1's greatest effect was probably the diversion of allied aircraft from more productive uses. Even after D-Day, there were days when just under half of the total allied air effort was devoted to attacking V-1 sites and intercepting V-1s. The political pressure on allied governments--especially the British--from their publics was intense. With the end of the war in sight, they weren't prepared to endure casualties from the V-1. The governments had to show they were responding and the air effort was that response.

[@williamzk9083]

-Operation crossbow cost the allies 200 fighter bombers and the Luftwaffe essentially lost no aircraft or FLAK guns in return. I doubt the launch ramps themselves were expensive. The V2 cost about 180 hours to manufacture and another 80 hours for the auto pilot. It's said that if a V1 hit a potato field in Britain the potatoes lost were more than the cost of the V1. The V1 was improving too with low cost wooden components being used for non structural components. -The V1 was actually to fast to intercept but deterioration of the reed valves in the engine dropped speed from 420mph to about 365-370 over the UK coast and allowed interception by hot roded fighters. Frank Reuters book on the A4/V2 and details experiments to increase the V1 with minor aerodynamic improvements and improved engines with higher pressure fuel systems that produced 480mph (in test), 495mph (in theory) and 515 (in theory). -Greg mentions that the V1 was never a precision weapon. In fact that was the plan with the Ewald II system in field testing. The standard V1 had an autopilot that used the nose anemometer to to measure distance and sequence one in flight direction change so that dog leg course would prevent radar back tracking. Initially 5% of V1 (increasing to 50%) contained an "Ewald I" radio beacon whitch was used to asses wind correction for subsequent missiles and asses accuracy. This probably lead to the 70% increase in accuracy. -In the "Ewald II" a clock on the V1 trigger a single coded pulse of varying frequency from the missile at about the half way point which was received by 3 ground stations in German controlled territory. Time differences were then used to accurately determine the V1 position and send a correction range and heading. The correction was stored as time differences on and endless loop magnetic tape on the V1. It was a cheap system and essentially unjamable since the coded pulse would be at the German end of the receiving stations before it could be detected let alone analysed and interfered with. -Obviously a second pulse could be sent near target. Assuming 100m radar accuracy and 3% of distance and the coded pulse was sent 2km from target you could expect about 150m accuracy.

[@dukecraig2402]

No, they had plenty aircraft to do whatever they needed them for, you claim that they could have been used for "more productive" things, like what? Destroying enemy equipment used to kill Allies? That's exactly what they were doing by attacking V1 launch site's and shooting down V1's, and they still had all the aircraft needed to do whatever else it is they wanted to do. By that point in the war it was the Axis powers who were back on their heels and were suffering shortages, those V1's didn't grow on tree's and at the end of the day any resources used to counter them wasn't even a kink in the Allies efforts but manufacturing them was a serious drain on Germany's resources. You've actually got it backwards, it's their resources that were drained and diverted by the V1's not the Allies.

[@brucebartup6161]

I think you'll find that USAF activity vs the V1 sites was limited to days when ther preferred targets were obcured by low cloud.

1st: love the channel. Thanks for posting this look at bombing accuracy. Stopped at : 00:00:49. My personal Corsair-a-boo guess? The P38. My reasons? Twin engine stability. The P38 is a known quantity as a precision ground strike weapon. Durability. I appreciate the "radiator" argument, but P38s took plenty of punishment, too, and most came home. P38 could carry overweight wing loads of bombs, could fly on one engine (something ya can't expect the P47 to do), was the testbed for underwing free flight rockets (which it rocked). Unlike the P47, the Lightning was always looking for a specialist role to fill in order to justify its Packard intensive existence. Without Luftwaffe bombers to hunt, it lacked purpose. Pressed into every possible role other than carrier air, it did well enough. But, as a frei jagd shoot and scooter, I believe it was the equal of any other plane. And P38 could under special conditions carry a couple tons of bombs . . .

[@GregsAirplanesandAutomobiles]

Yes, the P-38 could do well as a bomber, I have a video about just that comparing the Mosquito FB VI to the P-38G. However there is no data for them in the report on Crossbow. It appears they were not used for those missions, thus don't fit into this video.

[@StuartSmith-vn4jq]

Greg, If you haven't seen it already, there is some data on this subject in the book 'Mission Completed', a memoir by Basil Embry published in 1957. From May 1943, Embry commanded No 2 Group of RAF 2nd Tactical Air Force. On page 257, Embry has a table comparing the effectiveness of aircraft operated by British Bomber Command, British 2nd TAF, US 8th and 8th Air Forces against V1 launch sites during Operation Crossbow. He compares the performance of the Fortress, Marauder, Mitchell, Boston, Mosquito VI, and Typhoon fighter-bomber but does not include other aircraft such as the Thunderbolt. Embry concludes that the most effective of these aircraft was the Typhoon FB operated by Nos 83 & 84 Groups and the British TAF with an average of 0.68 aircraft casualties per site destroyed. Second is the Mosquito VI with a score of 0.87 and third is the Boston with 2.0. No source is given for this data. I hope this is helpful. Many thanks for another fascinating video.

Note, not the Sperry T-1, which was simply a version of the British Mk. XIV. SABS was very accurate, but was rarely used above 15,000 ft so there isn't much information on high altitude (if that's defined as, say, above 20,000ft) and they were hand-built so not exactly comparable to the Norden, the mass production of which exceeded requirements.

[@jacksonlarson6099]

​​@@sorryociffer I'll offer my amateur insight: the Norden company did an awful lot of myth-making for their bombsight, but that doesn't mean that it was actually a "bad" bombsight, as some people now like to smugly contend. It was an incredibly advanced system (and yes, it was a whole system, not just a bombsight). In the right conditions, with the proper training, it was better than any other bombsight (except for perhaps the Sperry bombsight, a US competitor with some advantages and some disadvantages compared to the Norden). In poor conditions, it was certainly no worse than any other optical bombsight. Detractors of the Norden often rely on criticisms that have nothing to do with the Norden itself, but rather are fundamental flaws with high-altitude precison bombing as a whole. A modern computer-based optical bombsight would still struggle if the weather is cloudy, or the aircraft is evading flak, or the navigator put you over the wrong part of the city. Like I said, in these conditions, any bombsight would be next to useless. However, in more ideal conditions, the Norden does indeed deliver higher accuracy than its contemporaries. Ultimately, the dream of high-altitude precision bombing wouldn't be fully realized until the proliferation of guided weapons, but that's not the bombsight's fault.

[@Billy-I-Am-Not]

this is totally me spitballing, but I would personally say that stuff like "best bombsight" is a relatively small contribution to bombing accuracy, and at the end of the day doesn't matter *that* much. After all, it doesn't matter if you have the best bombsight in the world if you're not *over the target* because of smoke, navigation inaccuracy, getting shot at, etc. And if the bombardier couldn't find and ID the target because they're flying at 30,000 feet past cloudcover, smoke, and 30mm minengeschoss, then the actual reliability of the bombsight is kind of pointless

You stated that you didn't know much about the story, and I thought you would like to know more. I left a long comment on that video with references, but in short, the pilot was my father's first cousin, Captain George W. Thornbrough. His story appears in the Time Life World War II series. As my comments there might suggest, I would also like to know more about the planes on the Lexington used in the Battle of the Coral Sea. P.S. I even like the car videos.

[@foreverpinkf.7603]

Well, that was both amazing and informative. Great work.

[@john-ug7nc]

I remember seeing that movie on the Wildwood Boardwalk I believe it was in the Strand movie theater. I was really into aircraft when I was a young boy. And seeing a V1 with Provisions for a pilot was truly fascinating to me. Then watching it fly and you're in the cockpit with the pilot was mesmerizing. Operation Crossbow (later re-released as The Great Spy Mission) is a 1965 British espionage thriller set during the Second World War. This movie concerns an actual series of events where British undercover operatives targeted the German manufacturing facilities for experimental rocket-bombs.

[@jiritalanda9695]

Greg, the use of Spitfire for this type of missions is very well described in the book called The Big Show, written by Pierre Clostermann

To your point about confidence in taking hits, that was one of the things I remember mohrle like to say. He would show people an 8mm bullet he fished from his parachute upon which he sat while flying, and go on about all the other hits he took, always coming back.

[@tomhutchins7495]

The Lancaster is a hard one to judge because it has such outliers of performance, and neither is due to the airframe. Line Bomber Command squadrons didn’t have a hope of hitting something so small: they weren’t trained to, especially against a tiny, camouflaged target. They were trained to aim at bright Pathfinder markers or at already burning cities. Meanwhile the other end of Lancaster precision with 617 Sqn is equally unrepresentative: these were experienced, dedicated crews who trained to achieve pinpoint precision with a unique weapon in the earthquake bombs (aided by the SABS bombsight and marker precision argued to be superior to the regular Pathfinders). Their impact is also hard to quantify as they successfully hit and destroyed the armoured underground factories of the V2, hit V3 before it could be completed, and many more. What is clear is that if you want to hit something small and avoid collateral damage, you have to go low in a tough plane.

[@wbertie2604]

@@tomhutchins7495 617 did take part in Crossbow. In one mission (near Abbeville, IIRC) it dropped its Tallboys with apparently a CEP of only 80 yards (I'm not sure from what altitude) onto the markers. Unfortunately, the markers were 350 yards off target. The main force of 100 or so followed up with 1000lb bombs, also on the erroneous markers, at least for the first dozen, after which dust and smoke obscured things. In many ways a great effort. In another, like trying to knock in a nail by dropping a bag of big lump hammers around the place. Or in this case, next to but not on the nail. The wrong tool for the job. Accurately marked, the Tallboys probably would have been sufficient as 80 yards was within the effective range.

[@mauricehodgson3143]

I think they also used their tall boys on U-boat submarine pens in France.

[@chadmueller6128]

Note that Greg DID NOT say that this means the allies should have used P-47s for ALL bombing missions during WW2. Different types of "bombers" are better suited for different types of bombing missions over others.

[@kevinkilleen6375]

Great breakdown on the subject.

[@johnduderidge9037]

I've seen frequent references to mosquito attacks, including V1 sites using a combination of low level and shallow dive bombing but never much in the way of exactly how or why. Two possibilities come to mind - 1. It allowed more planes to bomb in a smaller window? And / or 2. The 2 angles of attack helped split the defenders fire? It would be interesting to see if there are any stats for 2 Group RAF who carried out low level (largely daylight) attacks in a variety of British and American 2 engine bombers (Blenheim, Boston, Ventura, Mitchell, Mosquito and more.)

[@MrNicoJac]

I love any video that puts the P-47 or the Mosquito in a good light. In my opinion, two of the best planes in WW2!

[@mauricehodgson3143]

I think I remember someone saying nothing could beat a P-47 in a dive.

[@MrNicoJac]

Greg, you briefly touched upon this with the Thunderbolts, but for the other planes (especially the heavy bombers), was there any notable difference in crew training/experience? I could imagine that a veteran bomber crew would vastly outperform fresh replacements, regardless of the plane they flew.... 🤔

[@crusader5989]

Greg very obviously loves the P-47! And i can’t blame him😅

[@jacktattis]

Mosquito, P-47 and Spitfire also had the advantage of cannon and heavy machine guns as for light flak suppression.

Great video Greg. Thanks!

[@thisnicklldo]

It's a very minor point, and just for your info: the term 'ski site' came from the photo reconnaissance interpretation, and refers to the buildings labelled 'S' in you drawing shown at around 00:04:23. The point being that they vaguely resembled skis in overhead pictures. I believe it was several months after the first realisation that the ski sites were important, that the interpreters were able to identifiy the actual launch ramp - yes the photos were 3D, but the ramps are very low, and it needed just the right light and angle to see they were ramps - of course once they knew what they were looking for, it became more obvious, but these sites were first identified well before any V1's had been launched at Britain.

[@glypnir]

I see a few references to the A36 in the comments. It was a P51 modified with dive brakes and other things for dive bombing. 500 of them were made for primarily political reasons, and they were used in North Africa and Italy. They were not used in France that I know of. They’d make a great KZbin video. I suspect they were more accurate than most of the contenders on this list, and maybe even the Thunderbolts. The don’t use thunderbolts issue is another example of Glypnir’s rule of technology. In any technological issue the politics will exert 10x the force of the technical. I talked to a Tuskegee airman sergeant, and he told me that those big radials in front of the Thunderbolts were pretty good armor by themselves.

[@aussie6910]

I've read Leonard Cheshire used to dive bomb in a Lancaster to mark targets with flares for 617SQN at night. Quite stressful on the plane but it worked. One day he thought a Mosquito might be better, tried it & never looked back. The Germans were lucky there no SBDs in Europe (except for the Ranger).

Great data analysis. It would have been cool to have Typhoon/Tempest/Beaufighter data to have a heavier and radial British fighter bomber comparison, but alas for us, they weren't in the operation.

[@davidjohns4745]

The V1 was always termed the “Doodlebug” in England due to its doodling around once the engine cut and before the explosion.

[@stephenrickstrew7237]

Excellent episode as always .. but it does raise the question if which was the most accurate Bomb .. Turpitz was hit by the very first Tallboy dropped of the final raid .. It seems that a heavy and spin stabilized bomb would suffer less wind deflection and be a little bit more stable and predictable in its trajectory

[@tomhutchins7495]

Absolutely. The biggest challenge at that time was hitting anything reliably with it. The big factor in 617’s success was relentless crew training in precision bombing from altitude both day and night, using the precision of the SABS bombsight (a kind of British Norden equivalent) and the bomb’s consistency. Interestingly their biggest challenge was spotting targets, which led to the squadron borrowing first a Mosquito and later a USAAF Mustang to fly very low and drop marker flares or smoke. They would hit the markers, so those had to be very precise.

[@stephenrickstrew7237]

@@tomhutchins7495 I always wondered why the RAF didn’t use a Mosquito with the biggest version of a Tall Boy it could carry or a modified naval shell like what was used at Pearl Harbor ..The Tall Boys worked “ overkill “ in that they punched right through Tirpitz .. but the Mossie may have been a better plane for the mission .. with just a slight change in ordnance ..

Hi Greg. I have been trying to calculate max speeds in WT using in game data and have come across something strange. In my tests, I see that RAM air causes a loss of power below the peak altitude for a supercharger and a gain above it. Is it correct for RAM air to cause a loss of power like this? If so, why wouldn't pilots just shut off the ram air at certain altitudes?

[@dcbadger2]

Regarding you comment about the Lancs hitting the Tirpitz. A lot of bombs from many different aircraft were dropped on the Tirpitz, including a lot of earthquake bombs, with few, albeit critical, hits.

[@ColonelAkirNakesh]

Greg, amazing video as always. Do we know if any of the fighter-bombers used gun/cannon along with bombs? I love that Batumi, an airfield we know and love in DCS, is named after the Jug's designer.

Wow, P-47s are tough SOBs!😮 I would be curious about the P-38's bombing and ground attack applications as well. And there were two special variants, the Droopsnoot (with a bombsight in the nose) and the Pathfinder (with a "bombing radar" in the nose). As far as I know, the formation leader was one of the above and the rest were regular Lightnings with bombs. When the leader ordered the whole formation dropped the bombs at once. But there is not much info about that.

I have a question maybe you would enjoy answering How do the ballistics of a tail gunner work? I have no doubt that a golf ball size slug of metal suspended in air as a 300mph plane flies through it would suck, I was curious how trajectory would work as people led aircraft. What are the physics...but more importantly, how did they teach people to track them?

[@garydownes2111]

To add in response to some comments on this video: I think it would be honestly more valuable for commenters to try to find then post links to figures, data and statistics that would disagree or confirm those that Greg found. The obligation isn’t on Greg to go out and find data that agrees with your beliefs.. you can do that! It’s a tad trite to argue against data which may be admittedly limited without trying to make at least similar efforts to the content creator to actually research a topic.. you’ll find data is limited & Greg did great to find this & share it. Appreciation Greg & encouragement to others to go out and do the same rather than try to pick without support. Also this isn’t a top trump of aircraft types by fanboys like the Mossie lovers who seem to want to view everything as pro or anti that. It’s doctrine, mission type and pilot/ crew training & experience too with analysis based on data not feelings and bias.

[@GregsAirplanesandAutomobiles]

Good post Gary.

[@Allan_aka_RocKITEman]

Great video, Greg...👍

[@wuaf_devas9678]

So, I was right! My guess is, a P-47 pilot felt confident to approach target to very close distances before releasing bombs. Don't know what technique they used in real life, in Il-2 sim we used delayed fuses and dropped bombs from very low altitude. Usually, just a 100m or less.

[@SoloRenegade]

A-36 pilots were more accurate

[@edwardpate6128]

I wonder how effect an aircraft such as the A-36 Invader would have been. They were renowned in Italy for their dive bombing accuracy.

[@cocodog85]

greg...did the p47 bomb load consist of just HE or was there a combination of HE and napalm, cluster or other ordinance? therefore did the effectiveness of the strike also depend on the type of ordinance. i can't see the ski site doing too well after a nape strike.

Reminds me of a video from some other channel I don't remember that suggested that the strategic bombing should've been done with low level strikes by planes like the Mosquito rather than cramming a bunk of folks in 4 engine heavies at high altitude. I recall you did a video discussing this idea, kind of, but not that specific video's argument that it would've been more accurate and cost effective, IIRC. I believe they referenced the raid on Gestapo HQ in Denmark as proof of this claim. Regardless of it's veracity, it was a compelling argument.

The arguments ignore the entire mission of the 8th. It wasn't really about bombs on target. I have an entire video on the Mosquito as a replacement for the B-17 and I talk about it there.
