Brief history
At the instigation of the CSLA leadership, a new four-barrel rocket launcher was developed, modified for launching 122 mm calibre unguided air-launched rockets against ground targets. The Trenčín design was based on the vz. 70 self-propelled rocket launcher and the 122-JROF unguided rocket. Compared to the ground version, several changes were made to the airborne version to allow the rocket launcher to be used on aircraft and helicopters. For example, the firing method was redesigned, the rocket motor was shortened, and the sensitivity of the impact igniter to small angles of incidence was increased. The development of the rocket launcher was completed by Konštrukta Trenčín in 1986.
According to witnesses, one of the firing tests took place in 1989 in the military area near Malacky. A Mi-24V helicopter was used to carry the missiles. The missiles being tested were sometimes subjected to large long-range and lateral scattering. The cause was the airflow from the rotor and some flight modes. During the tests, so-called "pumping" also occurred when the helicopter engines sucked in larger amounts of burnt gases from the fired missiles.
The LRM-122 rocket launcher was offered by Slovak companies at arms fairs as part of the armament of light combat aircraft. The Czech Army got rid of these missiles in 2004 when it offered them for auction in large quantities, under the designation 122-JROF-L.
