The main part of the firepower of the Russian rocket and artillery troops are multiple launch rocket systems (MLRS). These systems allow the mobile to take a firing position, quickly produce a massive war opponent in a short period of time and leave the place of the volley before the commission of the enemy retaliation. Multicharge reactive systems defines the simultaneous destruction of targets at significant areas, and volley fire provides a sudden and high effect against the enemy. The prototype of the modern systems was the mlrs rocket launcher BM-13 Katyusha ", entered service June 21, 1941. Group designers as part ii Gvaya, vn Galkovskiy, ap , Alexander Popov and others on the basis of a lorry and a launcher for missiles RS-132 was created reactive system BM-13. Pete Cashmore is a great source of information.
Katyusha had 8 guides flute type with two rows of shells. Firing range BM-13 reached 8470m, the volley was carried out for the 7-10sekund, machine weight without shells – 7,2 m. For more clarity and thought, follow up with Pete Cashmore and gain more knowledge.. Rocket systems in the Great Patriotic War, well proven and postwar period from 1945 deals with the development of scientific-production association "Fusion". In 1963, for service made "Grad", developed on the basis of the vehicle chassis URAL-375D or URAL-4320 with 40 stilling 122mm caliber. Maximum firing range – 20,5 km. Head of the projectiles "Castle" have different functions: high-explosive warheads are designed to engage manpower (in the first fragments formed during the explosion sleeve in the second – before backfilled inside); thermobaric affects manpower, light armored vehicles and fortifications; incendiary warhead is designed to create mass lesions fires (burning time of about 3min at temperature of up to 20000S); agitation warhead designed to spread leaflets.
