128 mm M-63 rockets

M-63 rocket weighs 23.1 kg with the steel-cased warhead weighing 7.55 kg, 2.3 kg of which is the trotyl or trotyl-hexogen high-explosive filling. Threaded into the rocket nose is a UT M-63(OV) point detonating or super-quick graze function fuze; the fuze is armed at a distance of 40 to 250 m from the launcher. The M-63 rocket is 814 mm long overall. An inert practice version of the M-63 was produced. It weighs approximately 23 kg. The 128 mm M-87 Improved rocket weighed 25.5 kg, with 7.8 kg of solid propellant and an explosive warhead weighing 3.3 kg. Overall length with an M-84 point detonating fuze is 960 mm and maximum range 13,000 m. The 128 mm M-63 artillery rocket was developed for the towed 128 mm M-63 Plamen 32-tube MRS which was at one time produced in significant numbers for the former Yugoslav armed forces. The use of this towed MRS spread to virtually all the combatants in the area. As far as can be determined the 128 mm M-63 Plamen , the associated single-tube Light Rocket Launcher M-71 for special forces and their M-63 rockets are not currently in production. It is understood that the design of the 128 mm M-63 rocket was influenced by the Czech 130 mm M51 (qv). In 1988-89 128 mm M-63 rockets were supplied to the Austrian Army for use with their 13 cm Racketenwerfer M51 , the local designation for the Czech 130 mm M51 MRS. In 1989, an improved 128 mm rocket known as the M-87 was announced. Although it was intended for use with existing 128 mm launchers its current status is uncertain. However, an essentially similar enhanced range rocket, the 128 mm M93, is in production in Croatia and Bosnia and Herzegovina - see separate entry.
