Obrad Vučurović

R-25 Vulkan was surface to air rocket with development started in 1958. and Obrad Vučurović as led engineer.

M-63 Plamen was developed in 1963 as multiple rocket launcher in 128mm caliber with Obrad Vučurović as project manager and chief engineer of development.

M-77 Oganj self-propelled multiple rocket launcher development started in 1968. with Prof. Obrad Vucurević, who leaded developing and managed construction and production of the M-77 Oganj.

M-87 Orkan is 262mm self-propelled multiple rocket launcher development started as part of KOL-15 project in 1978. Obrad Vučurović had for KOL-15 significant financial backing both from Yugoslavia and Iraq. New rockets, launchers and vehicles where developed. Professor had practically all components designed by his engineers according to his plans, without paying to much attention to the costs as goal was to get best multiple rocket system at given time. The vehicle was also specially built in 8x8 configuration by FAP Priboj. From Germany, new equipment was bought from company Leifield for processes of cylinder press rolling for the formation of rocket engine chambers at the Pretis plant. The SPS Vitez imported new equipment for the extrusion of 160 kg of mew two-base smokeless solid fuel (NGR 375) for the chamber of the rocket engine. In total, in Yugoslavia, over 100 factories in the metal, chemical and automotive industries, telecommunications and electronics in Slovenia, Bosnia and Herzegovina and Serbia worked on the individual components of the weapon system KOL-15 and Orkan. The final montage on vehicles were don in factory "Bratstvo" in Novi Travnik, while complete rockets with detonators and fuel were finalized in Pretis-Unis (Vogošča). Special new alloys were required when choosing the steel and aluminum alloys in order to withstand pressures by new rocket engine. In particular, the launchers' pipes had to meet the highest requirements. For them, high-performance steels were produced in the Ravna steel mill in Slovenia, and the finished pipes were further processed in Pretis-Unis Bosnia nad Herzegovina. During initial tests few versions where developed and more than 500 missiles were fired. In addition to the Prevlaka and Luštica military test sites, it was Krivolak in the then Republic of Macedonia where the weapon system was also tested. The final tests for export customer took place in Iraq. A problem with the tests was the use of Cluster munition in rockets. It was not possible to use them at Prevlaka and Luštica over the Adriatic sea in order to see their deployment and explosion solid ground was needed. In Krivolak, several villages and all livestock had to be evacuated beforehand, as the sub-munitions often in test covered more area than planned. The Orkan M-87 was publicly presented on December 18, 1987. After delivery in Iraq in 1990 in the 0th series started, production stopped in 1991. Besides Iraq Turkey used Orkan M-87 as basis of their TOROS artillery rocket system after illegally obtained launcher and blueprints form Muslims in Bosnia during war. In late 1990s M-96 Orkan II modification was developed on basis of ZIL-135 vehicles that where used as part of 9K52 Luna-M.

As part of KOL15 project in 1989. started development of an army MRL RS-120 Uragan (eng. Hurricane) in 380mm diameter also known in latter stage of development as VERA(Velika raketa eng. large rocket) in 400mm diameter with 4 barrels and a 120 km range.[5] During project basic engine of 120 km fire-range rocket was tested and many domestic factories where involved.[6] While in Yugoslavia production of complete launcher did not start Iraq has produced rockets on basis of that technology known as Ababil-100 later renamed with new fuel as Al-Fat'h and mounted as single rail launchpad on 8x8 truck [7] while Orkan M-87 was known as Ababil-50 in Iraq.[8] Today technology obtained through VERA project is basis for new Advanced very long range Multiple Launch Rocket System, 400 mm caliber, range 200 km, quadruple, with rockets with INS-based trajectory correction system and fragmented warhead containing tungsten balls that is in development.[9] It was planned to start development of rocket with range of 350 km with Energoinvest Sarajevo as main investor but because of Yugoslavia war project was never finished.

Beside mentioned rocket systems(Vulcan, Plamen, Oganj, Orkan, VERA), professor Obrad Vučurović had other numerous project and scientific papers and task he worked on. Some of them are:[5]

• rockets and missiles: "Svitac",VBR-1, VBR-2, BR-10, PB-10, PB-20
