A forgotten development in the world of low-wing, monoplane fighters of the late 30s, the Rogožarski IK-3 was the most advanced fighter the Yugoslavs had at their disposal when the Germans came knocking at their border in April 1941. This is the story of its development, and of its service.

2 notes. At the time of engagement Yugoslav air force used both Hurricanes (licensed build) and BF 109 E, whats more they did extensive trails and mock up fight between all 3 types of fighters, so they knew weaknesses and strengths of each fighter, that would explain relative success against Luftwaffe. Secondly, while IK-3 died at the start of WW2, its development and improvements would be fund in postwar production of S-49, a fighter born out of Yugoslav/Soviet clash (Infrombiro).

[@fifi23o5]

Another interesting fact. In early 1941 they tested a Hurricane with DB 601 from Me-109. Results were quite promising and flight characteristics improved. But then 6th of April happened...

[@nrudnjanin]

​@@fifi23o5 Yes. It was designated LVT-1. And there was internation to test IK-3 with RR Merlin from Hurricane...

[@beyondrecall9446]

By knowing their strenghts and weaknesses, they made the "Hurrischmitt", by putting the DB-601 in the underpowered Hurricane

[@williamkoppos7039]

Well done. Thanks for the non-computer narration.

[@ivanstepanovic1327]

Yugoslav pilots at that time had no tracer rounds, so those victories were scored without them, making the feat even more impressive. Also, Yugoslavia had several 109s purchased from Germany before the war broke out.

[@colinhooper1933]

Very Hurricane looking, both at the same crossroads of design

[@aviationdeepdive]

The D.520 did indeed also use a Hispano Suiza 12Y engine, the cowlings certainly have some significant similarities due to the shape

[@givenfirstnamefamilyfirstn3935]

A better wing than Sydney Camm’s modified Clark Y fat aerofoil (originally fabric covered) choice for the Hurricane.

[@zlatanclovecic1944]

The engineers of the time obviously learned from each other. The plane is a bit similar to Morane-Saulnier MS-406 or Czechoslovak Avia B-35 (same engine and similar construction methods), Dewoitine D-520 (same engine, but full-metal), Hawker Hurricane (similar construction methods, but different engine). Note that Yugoslavia was close ally with Czechoslovakia and cooperated on defence industry as well. The HS-12 Ydrs was the best engine available for both countries and was produced in license in Czechoslovakia. This might be reason for using it.

[@edfisher8725]

Clearly not as strong as the Hurricane or Dewoitine

[@guidor.4161]

Reminds me of an MS 406 but is much more elegant and streamlined

[@aviationdeepdive]

Thanks for the comment

[@MisterOcclusion]

It does have a strong French vibe

[@jonathanhudak2059]

And throw in elements of a Yak-1

[@TheLateBird7]

Once again, with your thorough and engaging coverage in text and images, you have made me appreciate and even grow fond of an aircraft that would otherwise have remained a historical footnote to me.

[@aviationdeepdive]

Thanks, appreciate that!

[@vespelian5769]

Fascinating. I have never heard of this aircraft.

There's a reason in the aviation world the phrase "If it looks right, it is right" exists.

[@aviationdeepdive]

And do you think the IK-3 looks right?

[@FRIEND_711]

[@WarblesOnALot]

G'day, Yairs, that'd be right, too ; d' y' know that...? And it turns out that the Only tricky aspect lies in Knowing What, precisely, exactly (prezactorily - even)..., "Right..." Looks Like....! To an observer sufficiently handicapped by Dunning-Kreuger Effect, who Affects to be an Autodidactic Revolutionary Genius of the Homegrown variety...; even such things as the Notoriously Ugly and Hopelessly Un-Airworthy "Christmas Bullet" have been thought to "Look Right"...(!). Look merely at the point that Shareholders paid for the Bullet's Construction, and then the US Army Air Corps Supplied it's Powerplant, free - "on loan". Knowing what looks Right Is really vital. Such is life, Have a good one. Stay safe. ;-p Ciao !

„Spitsky fireovič“ seems far more capable than the Morane Saulnier….406? with (I believe) the same engine

[@eddiepires3998]

Yes agree, the nose section does remind me of a Spitfire , the rear tail section resembles the French Morane Saulnier and the fuselage and canopy a little bit of Hurricane 😊

[@eddiepires3998]

Great research, good video. I learned something today . Through your video, we aviation enthusiasts get to know an otherwise forgotten fighter. 😊

[@joesutherland225]

One I hadn't heard of ,thanks!

[@zadzad4353]

When looks From the sides.. IK3 looks like a SOVIET MIG 3 and u.s P40 WARHAWK/KITTYHAWK.. And from a far, a bit like BRITISH HAWKER HURRICANE too... Kinda..😅

[@jonathanhudak2059]

Reminds me also in the nose section of a Yak-1 too

[@audionci]

@@jonathanhudak2059 Indeed, the 1st version of post WW2 S-29 (A version) was a revamp of Ik-3, re-using a later version Yak-1 engine (the Klimov VK-105, that was itself a Soviet development of the Hispano-Suiza 12Y that powered the original IK-3)

[@jonathanhudak2059]

@audionci pretty neat I didn't know there was a post war variant of the IK-3. I bought a book on the type, started reading it a few years ago and got sidetracked lol. Thanks for sharing 👍

[@dude126]

Very interesting post. Thank you.

[@lancerevell5979]

Very reminiscent of the Dewoitine D-520.

[@fractalign]

[@MrCateagle]

The IK-3 evolved into the postwar Ikarus S-49 with a Soviet engine and a bubble canopy.

[@nrudnjanin]

The S-49A had Klimov VK-105 and later S-49C had Hispano engines bought from France.

[@Lord.Kiltridge]

I have put this plane on the list for possible additions to War Thunder. All but one of my submissions would be rank one, 2.0 or less, but at least they entered service.

[@aviationdeepdive]

I agree, it'd be awesome to see this in war thunder!

[@elennapointer701]

There's a real Moraine-Saulnier/Hurricane vibe to this little beauty and it's a shame it's not more well known.

[@av7987]

On the base of IK-3 afterwar desing a prop driven S-49 intercepter/ groundatrack airplanes was produced and used till sixtiess in post war Jugoslavia.

[@jonathanhudak2059]

Great topic! I've always liked the lines of this cool little Yugoslavian fighter. Reminds me of a cross between like a Hurricane and a Yak-1. Cool aircraft too bad they didn't have a lot more of them on hand when the Germans invaded. Time to build my Azur kit! 😊

[@slekic]

It looks like a lot of other fighters of the era, but it was actually inspired by the Dewoitine 520.

[@givenfirstnamefamilyfirstn3935]

What do you mean by a ‘tail spin’? Time 8:34.

[@simonengland6448]

Your elocution and syntax is perfect. The content isn't shabby either. You can't possibly know how refreshing this is. I'd given up ever hearing English again. All of your contemporaries speak American with a vaguely English accent. Even 'kers my age, 60, who ought to know better. Subscribed. Edit; No disparagement intended, I hope to help. the vowel U, like the other vowels is strange in that it uses a consonant sound as the first part of the diphthong, /j/. the following sound is /u:/. As in you. Unless you're from the South Midlands, the only other culture to remove the /j/, that I know of, is American. That said, I don't give a toss. 99.9% accuracy in this day and age is nothing short of miraculous.

How could you possibly miss the tiny bit of voiceless lateral alveolar fricative in his „s“?

[@damienmaynard8892]

What about the IK-2 Ikarus? Fought alongside Yugoslav Furies and then along with some Croatian Rogozarski R-100's. Ik-3 appears to have elements of the Hurricane, Yak-1 and MS.405 - parallel evolution?

[@aviationdeepdive]

The IK-2 is definitely another aircraft I'd love to cover

[@neilturner6749]

Editing error: I think the photograph at 1:11 is of a BF108 trainer and not a BF109 fighter..…either way it’s definitely not a BF109E as labelled

[@aviationdeepdive]

It is a Bf 109, but I believe it's a B model

[@wirralnomad]

Definitely a 109 not a 108, but certainly an early iteration, most likely a D but also possibly a B or a C.

[@guaporeturns9472]

Can tell the designers were trained in France. Look at the tail.. and the cowling… and everything.

[@aviationdeepdive]

They could be somewhat convergent evolution design decisions stemming from the French engine

[@guaporeturns9472]

@@aviationdeepdive I think the Rogozarski design team actually went to France and got some "training” there.
