80mm M-39: The operational diglycol 80mm M-39 rocket is based on the trial 50mm M-35 rocket shell and weighs 8kg with a 0.5kg warhead and a range of 5900m. A special six rail launcher with two wheels is easily transportable and easily placed and has up to 65 degrees of elevation. 48 launchers were brought in 1940 for use by mountain troops and the Marines are also interested in a similar version. In 1941 the Infantería de Marina brought 48 launchers. From 1948 new ammunition increased the range to 6,050m.
150mm M-42: This is an enlarged M-39 design which entered service in 1942. The venturi is angled 22 degrees to impart spin and thus no fins are used. A ten-round tube launcher is used. The 150mm M-42 rocket weighs 31.8kg, carries a 2.5kg warhead and has a range of 7000m. From 1948 new ammunition increased the range to 7,100m.
