In 1975, the former nation of Czechoslovakia adopted a new shoulder-fire, man-portable anti-tank weapon in the RPG-75 rocket-propelled grenade. The weapon was akin to the American M72 LAW (Light Anti-tank Weapon) and was specifically designed as a single-shot disposable system, discarded after use. The RPG-75 was influenced by the Soviet RPG-18 series which appeared in 1972 and was taken on by many Soviet clients from Armenia and Azerbaijan to Ukraine and Uzbekistan.
The RPG-75 had a caliber of 68mm and an overall length of 890mm. As in the RPG-18 and LAW systems, the RPG-75 was extended when made ready-to-fire so its compact, folded down length measured a handy 633mm. Muzzle velocity was rated at 620 feet-per-second with a maximum engagement range out to 985 feet. Sighting was through a leaf-type iron fitting. Overall weight was 7lb. The fin-stabilized projectile fired had a penetration capability up to 300mm of Rolled Homogenous Armor (RHA).
A few notable marks of the RPG-75 ultimately appeared. The based model was known simply as the RPG-75 while the RPG-75-TB of 2009, an improved form, introduced a thermobaric warhead. The RPG-Nh-75 and RPG-Cv-75 were used in training and the RPG-Sk-75 was another special-purpose model.
The RPG-75 saw a modest library of operators appear for its time as a frontline weapon solution. This included Algeria, Georgia, Poland, Sierra Leone, Slovenia and various factions in Syria. The available Czechoslovakian stock fell to the newly-established Czech Republic after the fall of the Soviet Empire.
