The M-63 Plamen (English: Flame) is a 128mm multiple rocket launcher developed in 1963 in Yugoslavia for use in the Yugoslav People's Army.
Serbian Prof. Obrad Vucurović, mechanical engineer at the Military Technical Institute Belgrade was project manager and chief engineer of development of the M-63 Plamen and all other Yugoslavia MLRS until breakdown of country when he continued to develop for Serbia M96 Orkan 2. His knowledge and previous development has influenced new MLRS systems developed in Serbia in last couple of years including new 150 km long range MLRS witch is in project phase of development. His work is widely acknowledged and many of his unique developed features could be found on MLRS around world.
MRL M-63 Plamen main purpose is support of front-line units, with strong and sudden attacks on enemy forces. It can be also used against enemy structures such as encampments, airfields, industrial facilities, command centers, communication centers, storehouses, etc.
The M-63 Plamen consists of 32 Ø128mm tubes, which can fire original Plamen-A and Plamen B rockets with a range of 8,600m. The effect of each rocket on the target is equivalent to the effect of a 105mm artillery shell. All 32 rockets can be fired in either 6.4, 12.5 or 19.2 seconds. The launcher is mounted on a single axle trailer which can be towed by vehicles with an 800mm high tow hitch. The towing vehicle carries reserve rockets, so the battle complement is 64 missiles.
The M-63 Plamen was widely used during the Yugoslav Wars. It has also been sighted in the Syrian Civil War, used by rebel fighters under the Free Syrian Army.
