Until the late 80-ies of the Soviet Union military experts attached great importance to offensive large armored and mechanized units, a pledge which has been successful action bold, quick and decisive maneuver. Difficulty maneuvering advancing or advancing troops and causing them injury could be caused by installing minefields enemy advance or remote mining during the battle. Therefore rapid overcoming minefield breaching through passages in them has become an essential condition for combined arms portions and compounds combat missions.
Installing SD-77 “meteorite” – video
special self-propelled units were created to overcome the minefields (installation of SD-67 mine clearance, SKILLS-77), which were intended for breaching minefields explosive manner during the fighting. UR-67 was created in the mid 60s and after 10 years has been replaced by a new machine – SKILLS-77.
Installing SD-77 mine clearance consists of a base of a tracked vehicle, created on the basis of a multi-purpose lightly armored tractor (MT-LB), launcher and ammunition charges of two demining. Charge clearance is caproic shell diameter 7 cm and a length 93 m, filled with plastic explosive, inside which runs a detonating cord. Charges stacked in a special tank in the rear of the machine. Filing charges demining the minefield of the enemy by special powder rockets, towing charge in flight clearance.
Starting missile launcher performed SD-77 “meteorite” via a special remote control. At the end of the active portion of the flight path decoupler triggered, disconnecting missiles. Brake rope creates charge braking on landing. After charge fall machine pulls back, nataskivaya charge a minefield and straightening his. With remote control via wire electrical pulse is fed to the blasting detonating cord. Detonating cord is undermined and initiates the explosion of all the charge of mine clearance. As a result, the charge detonation detonate mines in a minefield and is formed therein for passage of equipment and personnel. SD-77 is floating machine and capable of producing the charge start when moving on water on the opposite bank, occupied by the enemy, in crossing water obstacles or amphibious assault. Installation SD-77 acts, usually, the detachment razgrazhdeniya conjunction with engineering vehicles razgrazhdeniya (Sure) and armored vehicle launched bridges ahead of the advancing mechanized infantry, tank units. At present time, the UR-77 is in service and parts departments of engineering troops of the armed forces of the former Soviet Union and the countries of the former – the Warsaw Pact.
