It's a really intresting analysis and I'm not hugley surprised, a lot of this comes down to doctrine and pre-war bombing theory. I think it's probably worth remembering how they were used; in the ETO typical B-17 and B-24 raids had to operate a lot slower - combat boxes were fuel hungry due to speed adjustments when formation flying, so most of the time they were going around 180mph and carrying a bomb load of around 5,000lbs. Lancs were operating in a bomber stream and so didn't have to speed and up and slow down the whole time, thus being more fuel efficent, and therefore could typically crusie at about 210mph with a 10,000lb bomb load. I suspect this is a lot of where the heat and light comes from - when you read about Forts doing a nine hour mision to Berlin vs. Lancs doing it in seven it looks like the Lanc is a lot faster, which, as you've so ably shown, is too bald a statement to make.

The Ju-287 (only one built, but, still..) did just over 600 MPH in it's test flights. It was captured by the Soviets intact. The Arado 234-C (4 were built) was able to fly at 575 MPH, and flew perhaps a dozen missions before those were destroyed in Bavaria by Germans prior to being over-run by U.S. troops.

Halifax late versions were comparable with Lanc in most performance areas, it was used in a lot more roles and was a lot easier since to get out of than a Lanc. I agree deserves more credit contributed a lot to Allied victory.

[@GeneralJackRipper]

For the same reason the most common mention of the B-24 are the words, "And the B-24." Halifax has a very small ego.

[@RobBCactive]

It's true the Wellington aka Wimpey had more positive post-war press because of Barnes-Wallis's geodesic construction which made it rugged, early bombers failed. The Consolidated Liberator was relatively ignored, as a pressman said he felt safer in a plane called Fortress. The Lanc & Mosquito are the Brit glamour boys, because they were used in highly publicised operations. Sinking the Tirpitz and Dam cracking out weigh any number of routine missions. The other point is I have seen the Lanc fly, both at displays and when driving through the countryside. It's harder to be excited about a plane that is paper and photographs.

[@ericadams3428]

The Stirling was limited by its ceiling at c16,000 ft, the Lancaster and Halifax crews knew that if Stirling's were below them they might have more of a chance. If the Stirling had a greater span and a fuselage 20 feet shorter it might have got higher.

[@gerrycoogan6544]

An excellent, objective video, Greg. I agree with you that the B-24 Liberator has been denied the acclaim that it deserves. The same should be said for the Handley Page Halifax. Both aircraft also had the versatility to be used in a variety of roles apart from their sterling service as heavy bombers. Incidentally, over the years, I met quite a few veteran Halifax crew members and not one of them would have preferred to have served in Lancasters instead. That tells its own story, I feel.

[@donbalduf572]

One thing that comes through loud and clear: Every aircraft design involves compromises and technical choices, both highly dependent on choices made in the design process. What do you want? Range? Speed? Armor for the crew? Speed at altitude or closer to the deck? The list goes on. It was true in WWII and remains true. No one gets to have it all.

[@bbrf033]

The lines for the B24 were the closest to straight on the graph. The liberator is my personal favorite WWII bomber. Amongst other achievements It helped to win the battle of the atllantic (the longest, and perhaps most crucial of the battles). Thank you for including the hopped up Lancaster at the end.

[@jimspackman8527]

My grandfather flew anti-sub patrols in the RAF. From his log books they flew at 500-1500 feet. The aircraft he flew in were Liberator GRV (B24D) and GRVI (B24H/J) but they all retained their turbochargers even though it would have made sense to remove them for weight saving. They did remove the de-icing boots though, if you see pictures of Coastal Command Libs they usually have silver leading edges on the wings. I think they probably left the turbos on as it would have been more trouble to remove them. The aircraft already had enough endurance, they were bumping on the limit of what the crew could deal with by then. 13+ hour patrols were common in these things, and excellent aircraft that it was, no-one is going to want to spend more time than that in one, particularly my grandfather, his navigators position was behind the front turret and got pretty cold and draughty!

The Grand Slam Lancasters were especially lightened to carry their 22,000 lb bomb. They had a terrific power-to-weight ratio after the bomb had gone. They were known as "clapper kites" after the English expression "going like the clappers", meaning "very fast". Their great wing area meant they could also out-turn most fighters.

[@clive373]

Thank you, I love "clapper kites" the RAF generated so much langauge! And interesting point, re the Lancasters turning ability.

Baloney they were NOT fast and could not out turn a fighter

[@raypurchase801]

@@jacktattis The Grand Slam Lancs were specially lightened. The English phrase "Go like the clappers" means "go very quickly", hence "clapper kites". A bombless Grand Slam Lanc had impressive agility, climb and speed. NOBODY claims it could outrun a fighter, but it was phenomenally quick for a four-engined bomber. The Lanc's vast wing area allowed it to turn in a small space at low speed. Fighters couldn't pursue and would fly past, because they couldn't luff-off their velocity in the same way. Swordfish pilots developed a manoeuvre involving a short climb and a turn. There's an account of a Swordfish which was attacked by two Italian fighters over the Med. The Swordfish carried out its special manoeuvre. The Italian fighters tried to stay with it, stalled and crashed into the sea. The DH Mosquito is claimed to be "fast". In truth, it was slower than a fighter. However, its fast CRUISING speed meant it was difficult to intercept. Unlike a Blenheim or a "heavy", it had sufficient speed to outpace a fighter until it entered cloud and disappeared from sight.

[@TheIceland2000]

Greg, thank you again for your excellent presentation of a/c performance. I like to add some points: that maximum speed is a result of engine performance and aerodynamics. But high speed was never meant as a main goal in development of those heavy bombers. It was rather payload, range, ceiling and survivability. Because of the power required for take off, there is a certain maximum speed possible. But during combat missions, that did not count. A combat box or a whole group tried to maximize bomb load and safe fuel. Thus, flying at an economical power setting was the ordre of the day. B-17 formations attacked at around 200 mph TAS. After the bomb run, they flew a little bit faster. Thus, they spent a hell of the time over enemy flak concentrations. Remember, they could not speed up and turn away singularly, since that would have made them pray for the Messerschmitts. The best protection was staying in formation. The slow speed of the heavy bombers benefited them after the Germans fielded jet a/c, since the Me 262 did not have speed breaks. The speed difference was such that the German pilots could hardly hit anything with their guns. It`s why they came up with R4M unguided rockets. Maybe, it was Hitler who thought about that problem as early as he saw the first ME 262... Ultimately, it were the designers of the F-86 and MiG-15 who addressed that very problem...

[@dianedougwhale7260]

So Hitler designed the MIG 15--Certainly not Stalin--he was a Georgian Peasant

[@kellyshistory306]

One of those good examples of where theoretical stats meet the real world so to speak is that for a lot of the war the Lancaster could not fly at its optimal speed because it had to stay with the other slower bomber types (Stirling, Wellington, Halifax) during night raids into Germany. Whatever the virtues of the Lancaster's speed at its operating altitude vis-à-vis the B17 and B24 at theirs, the Lanc was chained for much of the war to the slower bomber types it flew with. Not until late 1943 and 1944, when Harris had enough bombers to send out all-Lancaster or all Halifax forces to attack different targets, was the Lancaster actually able to take advantage of its good performance at its optimal altitude.

The recent introduction of Gee made it much easier for crews to navigate within the precise limits required for such flying, although there would always be wayward crews who would drift away from the stream"

Could you expand on this "fast and high is safe" strategy? Are there primary sources? Was it a priority in design and operation on offense (British) and defense (US) side? What about day bombing? Was there a better safety margin at higher altitude and speed? Were day fighters better flyers (speed/altitude) than night fighters? What about the night fighter platform without radars?

The UK did work on some high altitude designs - the Lincoln had a ceiling of 30,000 feet, and the Vickers Windsor went through protracted work, but none achieved service in WW2. A high-altitude version of the Halifax was shelved, as was the version of the Lancaster with a slave engine and no defensive armament meant for circa 40,000 feet. The UK looked instead to get B-17s and B-24s off-the-shelf while working on high altitude versions of its own bombers. Rsults were in Northern Europe, partly due them being early versions of the B-17 with issues with oxygen systems, incorrect employment, and the British crew peeing in the bomb bays, apparently.

I remember reading about a pilot, an RAF test pilot if I recall correctly, who engaged in a mock dogfight with a B-17. He spoke about how the extra power of the Merlins was decisive in permitting the Lanc to out perform the B-17.

[@dukecraig2402]

Nope, both had engine's rated at around 1,200 HP depending on what octane gas they were tuned for, but the B17 would out perform the Lancaster at altitude, only a very few Lancaster's flew with 2 stage superchargers and even then they can't match the performance of the turbo system that the B17 had when it came to consistent power at all altitudes and especially at higher altitudes, when the Lancaster reaches an altitude where it's supercharger can no longer provide maximum boost, even the rare 2 stage variant, the turbo will give the B17's engine maximum boost for another 10,000 feet or so for the common single stage supercharger Lancaster and probably 5,000 ft for the 2 stage variant. A B17 with a high altitude deep penetration bomb load out could fly 5,000 ft higher than an empty Lancaster could. The myth that Merlin engine's were more powerful than other engine's in the same displacement range like the Allison is just that, a myth, the narrative is based entirely on the P51 Mustang story but what everyone fails to realize or mention is that when the P51 was developed the only engine available was the Allison, at that time there wasn't a 2 stage 2 speed high altitude supercharger that'd been developed for the Allison engine simply because no one ever paid Allison to design one, aircraft like the P38 Lightning used the supercharger/turbo configuration that all other US Army aircraft used like the P47, B17, B24, etc etc. At lower altitudes the engine's built in single stage supercharger provides all the boost it needs, then at medium altitude the turbo starts to feed the engine's supercharger, with a 2 stage 2 speed supercharger like on the later variant Merlin engine that's the point where it'd shift into it's high range (high speed) to be able to continue providing maximum boost to the engine, the problem with that system is that it eventually reaches an altitude where it can no longer provide maximum boost to the engine but a turbo can continue to feed the engine maximum boost well above the altitude that a 2 stage 2 speed supercharger can, and unlike a supercharger that's driven off the engine that sucks up power being driven the turbo is a waste energy recovery system so you don't pay a 250 (or so) HP price like when you shift a 2 stage 2 speed supercharger into it's high range. The downsides to the supercharger/turbo configuration that the US Army selected to run it's aircraft engine's are expense, it costs a lot more to build a system like that plus they're bulkier, the turbo for the P47 was so massive it was in the fuselage behind the pilot, also you have heat issues to overcome plus the bulky ductwork for the turbo. Both systems have their pros and cons but when it comes to perform the turbo system is superior especially at the highest of altitudes.

Even in mid/late 44, there's an argument that 109Gs on MW 50 (ie near all of them) beat it out, and they certainly do in speed at most heights. The IX is a solid overall match for the Anton and early 109G in practical combat IMO. You can try to discount the later stuff as not 'ordinary', but it's a very large portion of the Luftwaffe by 45 just due to attrition. There's also the 150 octane card, but it's a pretty patchy subject as far as 2TAF operations go. I don't think it's a practical factor until late Jan/Feb, and even then doesn't fully close the gap. The reason the Spit IX didn't end up suffering from that like the V did is the general lack of air combat they saw by 45, especially because they were mostly doing CAS whilst the ~12 continental squadrons of Tempests and XIVs handled more than their fair share of air combat.

Thank you, that's an interesting comparison between those outstanding allied bombers, if I'd have been tasked to bomb anything, anywhere I'd have asked for a DH98 Mosquito, 'fly high, fly fast'.

Fastest Lancaster was the Mk-XXXVII. It was equipped w jet engines n had delta wing. The crews nicknamed this version "Vulcan"

Love to hear these type of videos meanwhile I'm sipping a cup of tea, next video maybe you can talk about the Halifax BIII?, Love that thing, my first scale four engine bomber

[@badraven9532]

I have read in more than one source that B17/B24 mixed formations were quickly ceased when it was found that the laden B24s were reaching target UNDER the B17s and being friendly bombed. This interesting video adds to my doubts as to the veracity of this stated issue. Greg please comment?

[@AnArcadePerson]

Hi Greg, thanks for this video. Apologies if I've missed it, but you seem to miss out the differences in daytime / night-time operations for these aircraft? Is this not a major factor that decides on the altitudes these aircraft would operate optimally at?

[@GregsAirplanesandAutomobiles]

It's a big factor, the B-17 could easily operated at night, the Lancaster could not operate in the day except in seriously contested airspace.

[@AnArcadePerson]

@@GregsAirplanesandAutomobiles Would you say the B17 was as suited to night time operations as the Lancaster? Do you think the B17 was or could have been as successful or even more so in the night time bombing role. Do you think both the Lancaster & B17 evolved into their different roles? Cheers

[@stephenporter5886]

Being able to get to the target is meaningless unless a bomber can carry enough bombs to do damage there. While the B-24 had a better capacity than the B-17, the Lancaster far outshone them both. At maximum bomb load, the B-24 could carry 8000 lbs of ordinance, split between the two bomb bays. The Lancaster could carry up to 14000 lbs of regular bombs in its single bay.

[@GregsAirplanesandAutomobiles]

That's incorrect. The B-24's maximum internal bomb load was 13,200 pounds. Also I would argue that getting the bombs on target are more important than tonnage, but I'll get to that in another video.

[@dukecraig2402]

At 14,000 lbs it's range would have been decreased to the point it probably wouldn't have made it to Berlin and back, that maximum range you see listed in Wikipedia isn't for a 14,000 lb load, plus the fact that it's altitude would have been decreased to the point that everything on the ground bigger than a 9mm handgun would have been shooting at them coupled with the fighter's that would have been all over them at that altitude and it's unlikely any would have even made it to the target, I can assure you there was NEVER a Lancaster that flew to Berlin with 14,000 lbs, it never happened except in your dreams and KZbin videos made by Mark Felton. Why do all you guys in England think that the RAF had aircraft that could defy the laws of physics?

[@stephenporter5886]

@@dukecraig2402 The Lancaster could carry a 14,000-pound (6,350-kg) bomb load to a range of 1,660 miles (2,670 km) at 200 miles (320 km) per hour. The Lancaster could even carry the Grand Slam which was a 22,000 lb (9,978-kg) earthquake bomb used against targets in Germany such as Bielefeld Viaduct, Heligoland Coastal Batteries and the Hamburg U-boat shelters.

[@dukecraig2402]

@@stephenporter5886 In order for the Lancaster to carry the block buster bombs they had to be modified including stripping out the few defensive guns they had, and their range and altitude were both greatly diminished. And once again, no Lancaster EVER flew to Berlin with a 12,000 lb bomb load, it's not as simple as looking at a map and drawing a straight line from an airbase in England to Berlin, first off that doesn't account for the time it takes for a bomber group to form up and meet other bombers from other bases, there's far more to it than you daydreamers think there is. Between the diminished range and altitude that a Lancaster would have flown at with a 14,000 lb load none of them would have made it to Berlin, at that altitude it'd been in the range of everything on the ground that could shoot, and at it's diminished speed there'd have been even more German aces. Never mind the fact that Lancaster's could only put 36% of their bombs on an entire city with the remaining 64% falling in the countryside and killing a couple of cows if they were lucky. The Germans made it very clear in their wartime reports that the RAF bombing campaign did virtually nothing to hinder their war effort while the USAAF's bombing campaign caused major interruptions to their war production. Compared to the B17 the Lancaster was a flop.

Awesomeness. Thank you for posting
