After the war, Ikarus, Zmaj and Rogožarski factories were heavily damaged due to the Axis bombardment in 1941 but also after the Allied bombings in 1944. Most of the equipment was also gone and around 1000 of the workers perished in war. Luckily, the designers and technicians managed to keep some of the plans so the Aero 2 and S49 (Ik3) planes could be built.
Ikarus who was merged with Zmaj and Rogožarski continued the production of aircraft untill 1961. You have to understand that because Yugoslavia wasn't in the NATO or Warsaw pact the defense doctrine had to consider both these alliances as potential enemies. The defense was based on massive partisan resistance and the relocation of key defense factories in Bosnia. Thus, after 1961, most military planes were built in Soko (Falcon) factory in Mostar. Some of the biggest construction projects in Yugoslavia were top secret underground air bases and command centers. A few billion dollars was poured into them and the construction took a few decades in some cases. One of the notable projects was Željava underground Air Base near Bihać with several levels and elevators for fighter aircraft (Yugoslav companies built several bunkers for Saddam Husein in later years). The other big project was Atomic War Command, built in mountains near Konjic.It could house several hundred people at one time. Željava was destroyed during Yugoslav civil wars but ARK is in pristine condition and open for tourists (everything is in place,from Tito's war cabinet to Bosna soaps produced in 1970 ;D )
This paragraph tried to explain why there were no projects after 1961. The Ikarus still lives and produces buses. They had to change their name to Ikarbus in 1992 due to the fact that there is a bus manufacturer named Ikarus in Hungaria. I believe that there exists Ikarus aircraft manufacturer in Switzerland or Germany who produces ultralight planes.
Ikarus prewar office building still exists in New Belgrade, now surrounded with apartment blocks (untill early sixties, Ikarus factories and Belgrade airport were situated in New Belgrade - prewar old airport hangars and Airforce command bunkers in nearby Bežanija hills still exist; modern Nikola Tesla airport was built some fifteen kilometers further west, in Surčin municipality)
After this lenghty Introduction, here are the projects:
Ikarus Aero-2B - two-seater basic trainer,1 prototype 1946(although the project was designed prior to WW2)
Ikarus AERO-2/B/C/D - two-seater basic trainer, 275 aircraft built from 1947 to 1950.
Ikarus Aero-2H - seaplane version of Aero 2B, four copies were made in 1950

Ikarus S-49A - fighter,45 units in period between 1947 and 1950.
Ikarus S-49C - fighter,112 units in period between 1949 and 1955.
Ikarus 1.Maj - two-seater tourist plane, 1 prototype, 1948.
Ikarus Trojka - (Trojka - digit three)two-seater tourist plane, 1 prototype, 1948.(Utva built 80 of these planes until 1955)
Ikarus 211 - two-seater basic school aircraft, 2 prototypes, 1948.
Ikarus 212 - two-seater transitional plane, 2 prototypes, 1948.(Utva built 60 of these planes until 1955)
Ikarus 213 - two-seater transitional plane, 2 prototypes, 1948.(Utva built 195 of these planes until 1955)
Ikarus 214 - twin engine multipurpose plane (light bomber, transport, parachute training),post war project of aircraft designer Sima Milutinovic. 22 were built from 1949 to 1959)
Ikarus 215 - twin engine multipurpose plane, 1 prototype built in 1949
Ikarus 451 - light attack aircraft, one prototype,fitted with 2 Walter Minor 6-III piston engines and a prone pilot cockpit.
Ikarus 451M - (Mlazni - Jet) Derived directly from the S-451 airframe, the S-451M substituted Turboméca Palas turbojet engines for the piston engines, in underslung nacelles at the same positions on the wing and conventional cockpit.
Ikarus 451M Zolja - (Zolja - Wasp)light training aircraft; Flown in 1954, the S-451M Zolja featured a stretched fuselage,folding wings, and engine nacelles centred on the wing chordline. Used to set a world speed record in its class in 1960.
Ikarus J451MM Stršljen - (J - Jurišnik - close support) (Stršljen - Hornet)The intended production close support version with tricycle undercarriage, Turboméca Marbore engines and cannon armament.
Ikarus Š-451MM Matica - (Matica - Queen bee, Š - školski - school) Two-seat trainer version, used for a world speed record in 1957.
Ikarus T-451MM Stršljen II - A single seat aerobatic trainer.
Ikarus 452 - light interceptor, 1 prototype, 1952
Ikarus 453 - experimental glider, one prototype, 1950
Ikarus Orao I - (Orao - Eagle)glider, one prototype,1950
Ikarus Orao IIC - glider, one prototype,1951
Ikarus 920 - transport glider,one prototype, 1951
Ikarus Student - tourist plane, one prototype,1952
Ikarus 522 - single engine transitional plane, 2 prototypes, 1952.(Soko Mostar built 112 planes until 1962 (due to similarities, this plane often played FW190 in partisan movies, I'm not certain about Kelly's Heroes appearance because Yugoslavia had P 47D's)
Ikarus Kobac - (Kobac - sparrow hawk)two-seater wooden glider, one prototype,1953
Ikarus Košava - (Košava - name of the wind common to the Balkans, two-seater wooden glider,2 prototypes, 1953.
Ikarus B-12 V - light interceptior with chevron wings, 1 unfinished prototype (1954 - 1958.
Ikarus Kurir - (Kurir - Courier)three-seater liaison plane, 166 copies were built from 1955 to 1962.
Ikarus Hidrokurir - seaplane version of Kurir, one aircraft was built in 1955
Ikarus Meteor - single seat metal glider, 2 prototypes built, 1958
Ikarus Lightning - two-seater wooden glider, 1 prototype, 1958
The pictures show the Ikarus office building, plaque on it that commemorates workers who died in WW2, old airport building and MIG 21 in underground base (I'm not sure if it's from Željava or Slatina air base near Priština).

Hi bigvlada :D
Thank you for the detailed information on Ikarus and especially the historical part !!.
Haver you ever heard of a Model 231 which I understand was built as a prototype (1948 or 1951).
I strongly resembled the Model 211, but had an enclosed cockpit.
Best regards, Walter

Yes, the 231 was 211 with enclosed cockpit. It's intended role was courier service. Both were prototypes. 212 and 213 were mass produced by Utva.
The reasoning behind the 211/12/13/31 was that Yugoslavia lacked pilots after the ww2 and refused the soviet training methodology with PO-2 and UT-2 planes. Instead, the pre war royal yugoslav aviation methodology was chosen instead. We had Tiger moths and Harvard's which were suitable for this role but only a handful of them were available (20 and 11 planes respectively). Thus, in the following competition (Bulgaria was also allowed to participate, with Zvetan Lazarov's LAZ 7 design) Ikarus designs Aero 2b (a pre war project) was chosen as a basic school aircraft and 212 and 213 as transitional aircrafts.
Because 213 had better results during the tests than 212(although both planes had the same engine, mass and basic dimensions) it was built in larger numbers.

I can see a real parallel between the Ikarus 211 and the American NA-16 and NA-35 prototypes. And I'm sure one could identify a dozen similar design all over the world at the same time (including some Miles and Caudron types).

At http://alternathistory.com/kukhnya-maiora-beshlina-yugoslavskaya-reaktivnaya-programma-1950-kh-godov-chast-1 and http://alternathistory.com/kukhnya-maiora-beshlina-yugoslavskaya-reaktivnaya-programma-1950-kh-godov-chast-2 you may find a two-part article on development of jet aircraft in Yugoslavia in the 1950s by Dragoljub Bešlin.

The article originally was published in the "Aviacya i Kosmonavtika" magazine (issues 9 and 10 of 2013) and obviously is in Russian B)
