[@Niinsa62]

I read somewhere a long time ago there was a fan club of this aircraft in America. The aircrew of an American bomber that had been damaged and was trying to reach neutral Sweden to make an emergency landing. To stay in the air, they had dumped everything heavy overboard after they left Germany and reached the Baltic Sea. That meant guns and ammo. Unfortunately, before they reached Sweden, they were attacked by a lone German fighter. They could do nothing to defend themselves, so things looked kind of grim. All they could do was look at the German fighter as it made a pass firing at them, and then climb away to slow down, make a turn, and come back firing at them. Only he didn't come back, because as he was slow and turning, a Swedish fighter opened up on him. A J22. He didn't shoot the German down, but he scared him away. The J22 pilot had seen what was going to happen, and had been going full throttle, engine temperature be damned, and had managed to place himself in a good position to do something. And then the J22 escorted the American bomber to Sweden so they could land there. The J22 pilot met them afterwards, and his surname was Smith, oddly enough. Apparently, he was a brother or cousin or something of famous SAAB test pilot Claes Smith. Smith is not a common surname in Sweden. That American bomber crew formed The J22 Fan Club, American Chapter. Maybe not the fastest or bestest fighter ever, but it was there, when it was needed! :-)

[@damienmaynard8892]

There was another incident where a heavily damaged B-17 only had fuel enough to reach Sweden from Northern Germany or Poland. No Germans pursued them but they were intercepted by Swedish fighters. They were warned over the radio to turn away or be fired upon. They replied "We know!" and kept going. This happened twice more. The fighters dropped back and opened up - way too far behind. The B-17 radioed to them "You're shooting too far back".. the Swedes replied "We know!".... the B-17 crew landed safely and were interned for a month or so, in comparative luxury, until the war ended. Sense, sensiblity, timing, training and knowing when to seize an opportunity or to ignore the immediate result and think long-term. It's the man as well as the machine which makes a good stridspilot.

[@arudegesture]

@@damienmaynard8892 Sad to say this is most likely a myth. The same story exists about allied bombers flying over Sweden, being warned over the radio that if they don't turn around AA batteries will open fire. Then when the AA batteries do open fire they're firing too low, which precipitates the same conversation. "You're firing too low!" "We know!" One thing that DID happen was Swedish fighter pilots from time to time engaging German planes near the coast of Denmark and then flying back to Sweden. There are several accounts of this given by pilots themselves. And, of course, Sweden did fire on and, in some cases, brought down a handful of German planes who took a shortcut across Swedish airspace.

It sounds like you've mistaken this for the incident where JA37s supported and covered a SR-71 mission that had blown an engine in 1987.

[@nomennescio4604]

About the Pratt & Whitney engine. They way I have heard it told, apparently the Swedes were perfectly aware they were nicking it. What they did was start an account on P&W's behalf, make an assessment of what should be an acceptable sum of reimbursement per engine, AS IF there was an actual agreement in place, and deposited the sums there. And what then happened after the war was that a Swedish delegation went to P&W, and as a total surprise to the P&W people presented the situation, with yay amounts of pirated engines produced, but also this fat back account with payment for P&W set aside, should they want. It is then to the very great credit of P&W that that absorbed this surprising new information, and swiftly came back with the purely symbolic one dollar claim, and besides they expressed their great satisfaction that the Swedes had chosen their engine as their best option in a time of national emergency.

[@bodan1196]

Considering that the Bofors 40mm anti-aircraft cannon was manufactured in the 10th of thousand, without a licens... I think that the one dollar was an nice compromise. In a larger picture so to speak. I have actually heard, somewhere, the proposition that the two "infringes" were concidered, by the governments, to balance out each other. Though unlikely true, it would be... comforting(?) if it were. No?

[@TzunSu]

@@bodan1196 Where did you hear that the Bofors was produced outside of licensing agreements? Both the allies and axis paid licensing fees to Sweden during the war.

[@bodan1196]

@@TzunSu While I can't name from which books, papers or from which historical documentaries I have formed my "knowledge" on this, I find my recollection of having read and seen the information in trustful media, undoubtful. I have the recollection of having seen an interview with a person who was involved with the swedish TwinWasp project, who after the war also was present when the licensing issue were brought up, and the licence were "adjusted" with a shrugg and towards the 40mm. While Wikipedia is not an inerrant source, there is a, perhaps tenuos, mention that it was, on the swedish page. That licening fees were payed to Sweden, does not mean that there were in all instances.

@@TzunSu Search for _Aeroseum TwinWasp_ and you will find a short video about the swedish TwinWasp. (I didn't search for it. The algorithm presented it to me.) The US did have a license for the Bofors 40mm, to manufacture for their own use. The US did however lend-lease, and give manufactured guns to other countries, which they did not have a licens to do. This breach of terms of licens, was the "thing" that was used to balance the reverse engineered TwinWasp. So we were both right, just not completely so. Be well.

One thing of note, Swedens armed forces didnt have much when the war broke out, but the Swedish army and airforce gave what little they had. One third of the fighters went to Finland and also much of the armies artillery, machine guns , AT guns and AA guns and ammo of course. Total value of what was given during the Winter war 39/40 was 500 million SEK, which was 50% of Finlands budget total or military total cost. Either, doesnt say which in my sources, but either way, a lot

[@DIREWOLFx75]

When the war started in September 1939, Sweden had at most ammo for around 2 hours. And at worst, for less than 15 minutes. The big problem was that when Sweden tried to start rearming in 1935, it was already too late, vast majority of suppliers were already busy producing things for their own nations. The navy was old, but not quite obsolete, as their focus would be on using the coastlines to stay defensive and hit anything getting close, no gallivanting around and risking the big ships. The army was mostly old, to some extent on the edge of obsolescence, but also with some level of modernisation, mostly thanks to the Germans circumventing the Versaille diktat by setting up the Landsverk company in Sweden, developing mostly tanks. Now, the AIRFORCE however? In 1939 most of it was painfully obsolescent or even outright obsolete. And it wasn't big either. And Sweden had not a single manufacturer capable of massproduction of high performance aircraft engines, nor any designer with experience creating one. Sweden purchased a small number of planes from Germany. They were not however capable of getting any of the "latest'n'greatest", just some minor upgrades in overall capability, like getting a few Ju-86 high altitude recon/bombers. Sweden went to USSR. And COULD have gotten a quite decent deal for I-16s there, which would have been a clear improvement on existing planes. But because the Soviets refused to also sell bombers, Sweden crashed the deal, very stupidly. Sweden went to JAPAN even. And almost concluded a deal that would have been amazing for Sweden. Deliveries of the Mitsubishi Zero starting the same time they started delivering them to the IJN. And COMPLETE license rights for everything needed to build a Zero, with especially the engine and cannons as well as the alloy used in the airframe being extremely important as Sweden at time completely lacked the expertise and knowledge for those areas. This would also come with both deliveries and licensing for a bomber, possibly more than one, but i've never been able to find out which one. However, due to the fighting with USSR, there was no way to get any deliveries overland, as the optimal solution would have been to send them via the Sibirian railroad. And during the negotiations, the war in Europe had started, which made transport by sea exceedingly dangerous. There was more negotiations regarding a possibility of buying only the blueprints and licensing rights, but with USAs increasing sanctions against Japan heralding a future war, Japan became much less enthusiastic about potentially giving away secrets without getting enough in return, so their asking price for blueprints and licensing ended up simply too high for Sweden. Sweden purchased aircraft from USA. And before barely any had been delivered, USA broke the contract. At least SOME of the engines had arrived, and this was used to reverse engineer and make an improved version of the engine a few years later. So, what did Sweden actually get in numbers? From the only place selling and available. Italy. A bunch of Reggiane 2000. And, as a result of a privately organised collection drive, also a bunch of Fiat Cr.42.

[@antonsamuelsson1317]

That with the zero, search j-19 Saab it was the blueprint and everything was finished in september 39

[@DIREWOLFx75]

@@antonsamuelsson1317 J-19 is NOT the Zero. It is perfectly possible that it was inspired by it, but as far as i know, none of the Swedish designers had ever seen the Zero before designing it. So, the similarity is most likely coincidental. But no, Sweden actually negotiating for the actual Zero, is another thing. If they could have managed a functional deal for delivery, Japan would literally have started its own production at around 50-100% higher than historical, and delivered half of the first 400 to Sweden. There was also talk about getting access to more of Japans engines, and at the time, Japan was one of the world leaders for radial engines, which would have been an exceptional bonus for Sweden, especially as Sweden did not have the issues with poor manufacturing precision that ruined the actual performance of the Japanese engines.

[@WolfHeathen]

True. We didn't become a great air force power until the mid-50's when we had the fourth largest air force in the world. The reason for why Saab AB is so massive in the aerospace and defense industry today is pretty much only because the US cancelled that contract and the Swedish government had to rapidly develop their own technologies.

[@TzunSu]

And then we went back to the Italians after the war, buying up a ton of their old surplus planes. My grandfather was in the air force from 42 until his retirement, he lost a *lot* of friends when those shitbuckets went down. They routinely found random junk, tools clothes wine bottles etc, inside the fuselage and wings.

[@Niinsa62]

About Bodafors who made the birch wood panels. There is a team restoring a J22 to flyable condition here in Sweden, Warbirds of Sweden, mentioned in the video. I attended a lecture where they talked about their project. They said that when they contacted Bodafors and asked if they had any info at all, on how to manufacture those panels, Bodafors answered they still had some of the jigs and tooling, and most of the documentation on how to make the panels! And part of the staff at Bodafors volunteered to make a new set of panels.

Very interesting, thanks. Sweden enjoys a well deserved reputation for innovation and quality and the J22 is a good example. Cheers.

The newspaper headline (April 10, 1940) reads, 'Germany demands strict neutrality by Sweden' - in other words, do not get involved in the Nazi war. With the weak military capability of the Swedes, no wonder they obeyed.

[@Rbajter]

Also, in order to be regarded as neutral you could not be seen as a threat, so the military could not become too strong.

[@annoyingbstard9407]

And all the money they made supplying the Nazis with everything they needed helped….

What a great looking ship! And the innovations used to build it are great. Ahead of their time with the gear configuration as ALL modern fighters have the gear retract in the fuselage now, even the B-52 and transports as well; structurally, it makes sense. The honesty of the engine license gesture speaks volumes about the design team's character. I also read that customers who ordered Volvo 444s pre-war were only charged the pre war price when they were finally able to get their car after the war and production was able to start in 46 or so. A pretty good way to be.

The converted torpedo boats used as blockage runners were the Gay Viking class had been ordered from Camper and Nicholson of Gosport and Northam by the Turkish Navy just before the start of WW2. They were powered by three 1000hp Paxman VRB 16 cylinder engines. The Turks had ordered 8 of these boats and three saw service with the Royal Navy as MTBs and the other 5 became fast merchant men (Gay Viking, Masted Standfast, Hopewell, Nonsuch and Gay Corsair) and crewed by officers from Ellerman Wilson and crewmen off Hull trawlers. These boats could cruise at 20 knots, with a max speed on 23 knots, at 17 knots they had a range of 1200 miles. Look up Operation Bridford to find out more on their service.

Great video and a very interesting subject! A litle additional information: The macineguns mentioned as 7.9 mm in calibre was actually in 8x63 mm (8 mm cartridge m/32), even if the bullet diameter was the same as the german 7.92 mm. The m/22 mg was a Swedish variant of the .30 AN/M2 from FN, that was a variant of the Browning m/1919. The mentioned "cannon" was international known as the 13.2 mm FN Browning. In Sweden the designation was "auto cannon" due to the use of ammunition with mainly high explosive projectiles.

[@Arthion]

Fabrique National were quite nifty in being able to design a high-explosive fragmentation shell that small. The FN Browning 13,2 really blends the line between HMG and autocannon.

[@Mattiniord]

Svedinos J22 that is being restored to flying condition by Warbirds of Sweden is alive and kicking. But it has been moved to Aeroseum, a Museum and Aviation expirence center in Gothenburg. Aeroseum lies in an Cold war underground hangar by Säve airfield, the former home of F9, the first unit to be outfitted with the J22 in late 1943. Therefore visitors can come and see how the work progresses on the J22. They started out with the metal framework but little of the original wood for the hull and wings. What remained was not useable anymore. However, Warbirds of Sweden had a stroke of luck. Remember that furniture manufacturer that produced all the wooden components? When asked if they could help out, they had a look around and lo and behold, in their storage they found drawings and all the original moulds that had been used to shape the beechwood panels! Thankfully someone way back when had made sure to store these, maybe thinking that maybe they might become useful someday. The company would never make anything like that ever again, but just by preserving those moulds did an extremely important service to swedish aviation history. So now the aircraft will be clad in newly produced beechwood panels, made using the original moulds, which frankly is mindblowing. After all, there was really no need for the company to keep those moulds, but keep them they did. If you want to see the the work on what will hopefully become a fully flying FFVS J22, come to Gothenburg and visit Aeroseum.

[@johncashwell1024]

@9:47 - "...illegal..." would be the wrong term. As an attorney, I come across the misuse of this word often. Legally speaking, "illegal" refers to criminal law. Whereas, in this case, the Swedes created copies of engines that were protected under patents. Patent law is a mix of common law (from higher Court decisions), legislation &, depending upon jurisdiction, some administrative law and civil law. In Sweden's case, the reproduction of engines that were protected under US & Foreign Patents without first paying for or gaining permission for the use of the patents from the patent holder made them liable for that unauthorized use. Liability is the exclusive purview of civil courts. In criminal law one is guilty or not guilty & in civil law one is liable or not liable.

[@SPavlo]

Thanks ! Quite an insight of how Sweden was actually forced to grow a sovereign aeronautical industry. Funny to note that Saab was originally a hindrance more than a help for this first domestic fighter, but it resulted in an original construction.

[@christopherboyle1479]

In Australia, similar strategic circumstances led to the hurried design and construction of the CAC Boomerang, which also used the P & W R-1830 and is very similar in appearance, layout, and general performance to the J22. The Boomerang was started a year or more earlier, and used the wing of the NA-16, which was already being built under licence in Australia. As there are flying examples of both aircraft, would it not be wonderful for an air show to bring them together somewhere, somehow? The pilots of each type praised its flying characteristics, particularly turning performance. That was the thinking of the biplane fighter era: I fear that just as the Boomerang proved inadequate against the A6M and the Ki-43, the J22 would have had no answer to the superior speed, hitting power and performance at altitude of the Bf 109 and the FW190.

[@aviationdeepdive]

Yes, the CAC Boomerang is interesting, particularly in that it actually adopted more of the asian doctrine of turnfighting, whereas the J22 had more of the European doctrine of speed. As such, the CAC Boomerang and J22 are actually quite distinct in their performance. The J22 is a lot faster, about 50 km/h at sea level and over 100 km/h faster above 4,000 metres. However, the Boomerang was a much better turner, being just mildly less manoeuvrable than an A6M2. Both interesting aircraft. As I recall the Boomerang also once engaged a Japanese formation of bombers but was unable to secure a definite aerial victory.

The FFVS J22 had a credible speed of 350mph consider the PW R-1830 double row radial's limitations. It's similar to the Australian Wirraway which had the even less suitable single row CW R-1820. It should be noted that the Me 109G1 was entering service with a speed of 400mph and the Fw 190A3 with a similar speed in early 1942.

About the Pratt & Whitney engine. It was not necessary yo convert its dimensions to the metric system from the Imperial system because it had been designed and built in the US, and the US never used the Imperial system! The US Customary System of weights and measures has many units with the same names as those of the (British) Imperial system, but which were not the same size. For example, the British S.I. gallon was 4.54 liters, but the US gallon was 3.78 liters. This caused some difficulties when plans converted from metric by the British were passed to the US: US built 20mm Hispano-Suiza HS404 and Bofors 40mm cannon were not interchangeable with British built models. Of course measuring the parts on the Pratt & Whitney engines that were already in Swedish hands gave more accurate metric dimensions than doing mathermatical conversions.

[@aviationdeepdive]

It definitely was not created with the sympathy of communism in mind. It's just getting at the fact that at the end of the war in 1945 the 'Allies' (i.e. the name of the faction) had taken over Europe. I'm not saying that the Soviet Union was necessarily, or should have been, an ally.

Would anything built under license, like DB601 engines fx, be a breach of neutrality?

[@JH-lo9ut]

Not if Sweden was building for their own use. Sweden imported war materiels and weapons from both sides during the war, whatever they could get hold of... Famously, Sweden also exported raw materials and machine parts like ball bearings to both sides. I'm not 100% sure about where the lines were drawn when it came to exports. Both sides would have sanctioned each other, and put each other under mutual blockade. Breaking a trade embargo is one thing, breaking a naval blockade is another...

Wait. What? [11:19] A retractable Lysander for Finland? That's new to me.

[@ivancho5854]

Me too. There's also a second small wing.

[@HootOwl513]

@@ivancho5854 The winglets were on the early model, the Mark I, and 4 small bombs [20 Lb HE] could be hung on each side. The massive wheel spats each housed a .303 MG. Finland bought about 13 aircraft from the Brits. Mk IIIs deleted the winglets. My guess is that Finnish Intelligence airbrushed out the Landing Gear to fool the Soviets. There is nowhere for the Gear to retract to in that configuration.

[@ivancho5854]

@@HootOwl513 Ah, yes I recall the small wing with those little bombs now. Funny, we're used to deception today, but I hadn't considered that the photo could have been altered. 🤦 I suppose they could have mounted skis in addition or instead of the wheels and were trying to conceal that, or simply the very distinctive wheel fairings. It's an interesting photo now that I think about it. Thanks for your comment. All the best. 👍

[@HootOwl513]

@@ivancho5854 Even retracted skis would have been visable. Landing on the winglets as snowfoils would not have worked, as their bottom is inside the Prop Arc. [As if they could even take the stress.] I will have to stay with the propaganda/deception angle. ''This plane does not look scary with those rediculous wheelspats'' the censor must have coimmented. I enjoyed our discourse also. Cheers.

A (fraught and difficult) suggestion for future content...aircraft development and manufacturing in occupied & Vichy France...

[@bobhamilton298]

You mentioned that the landing gear was similar to the P40 that tucks into the fuselage. The P40 retracts its wheels backwards into the wing, not fuselage. This plane is more like the F4F Wildcat (and F3F) that tucks its wheels into the fuselage.

[@ivancho5854]

The video is correct as he was describing the way that the wheels rotated 90° to lie flat, not the location of the wheels. Listen to that part again and also watch the footage of the retraction and it will be clearer than my explanation probably. All the best. 👍

[@magnushallberg936]

Good video. However, correction F16 Uppsala not F19.

Finland never had an alliance with Germany and we were it hostile to Sweden. In fact Swedish volunteers fought in the Finnish army.

[@aviationdeepdive]

The Paris Peace Treaty judged that despite Finland and Germany's attempts to describe themselves as 'co-belligerents', they were - in fact - allies, in virtually every sense of the word, insofar as it has any meaning.

[@johanmetreus1268]

@@aviationdeepdive The Paris Peace treaty also cited Germany as the sole invader of Poland in 1939 and failed to address things like Operation Wilfred. In reality, the Continuation war saw Finland conducting a war with the limited aim to restore the land lost in the Winter War, which is why the advance stopped well north of Leningrad. This caused much dismay in Berlin, who wanted Finland to fully commit to the defeat of the Soviets.

"When war broke out in September 1940..."!? And what was going on in Poland the year before? Oh well, World War II didn't start for the United States until late 1941...

[@nattygsbord]

The great patriotic war started in june 1941 with the invasion of russia. I do not wanna be reminded of Soviets unjustified wars of aggression against Poland, Finland, Estonia, Latvia and Lithuania so I want to pretend that world war 2 did not start in september 1939.

[@JH-lo9ut]

Germany and SU's invasion of Poland was in september 1939. Britain and France declared war on Germany the next day. However, not much fighting took place between axis and allies (except between Germany and Poland) until may 1940. During this time, Sweden's main concern was the Soviet invasion of Finland. (The intermittent period is sometimes called "the phoney war"). So, it is not right to say that the war started in 1940, but it is also not entirely wrong, from a western european perspective. What happened in 1940 was the invasion of France, the low countries, Denmark, and Norway, and Britain's retreat from mainland Europe.

[@karoltakisobie6638]

Swedish skies weren't quite incursion free. Both RAF and USAAF bombers often crashed or landed in Sweden, lots of Luftwaffe planes escaped to Sweden in 45 and Soviet planes repeatedly flew over Swedish coastline. Soviets bombed Stockholm at least once.

[@johnblackstock4092]

My Uncle Angus, was an Australian Drill Sargent during WWII, he said to me one of the reasons Germany did not attack Sweden, was that the Swedish Government had armed its civilians.

[@hurri7720]

No truth to that though. Sweden delivered iron ore to Germany until the end of the war and German trupes were allowed to travel through Sweden. No need to occupie. A few hundred Swedes died due to WW2 and if the government's task is to save the people then they did very well. But Swedes that are too eagerly claiming big deeds in WW2 annoy me a lot. The private help delivered to Finland was appreciated also accepting Jews from Denmark into the country was fine. And when Finland had to push out the Germans from Finland they went to Sweden of course. Sweden did not have much of an army then or today. But it will get better now I believe.

Um, more akin to the P-64, or P-43, but Not as 'Old' (by a year?) as the P-36 or F-4F., yet Not like the F-4U of 1940, yet. SAAB would vindicate itself with the J-21A, and soon later, the J-21B.

[@williamleadbetter9686]

I'll bet a J.22 could whip a FW 190 in medium to low altitude combat.

[@kirgan1000]

and the Luftwaffe was in love with Boom & Zoom tactic, so only a green German pilot will continue to fight at medium and low altitude after the attack dive, instead of climbing up to safe altitude, using the FW 190 superior energy state (and enormous advantage in Hp)
