In 1971, the Polish Military Institute of Defense Technology initiated project “Argon,” aimed at developing an anti-tank grenade launcher with a single-use launch tube as a supplement for the RPG-7.

At the time, the weapon was designated “HEAT grenade with single use launch tube RPG-73.” A series of prototype launchers was produced in 1980.

With the warhead incapable of penetrating the front armor of modern western tanks it became an auxiliary weapon, not replacing standard issue RPG-7 grenade launchers in infantry squads.

[2] In late 1990s it was withdrawn from front line units and store due to limited anti-tank capabilities and increased safety demands (a lack of self-destructor).

[2][3] Polish soldiers also used a small number of heavier multipurpose Carl Gustav recoilless rifles using a variety of modern ammunition types.
