The 122-mm howitzer D-30 is a Soviet howitzer that first entered service in 1960. It is a robust piece that focuses on the essential features of a towed field gun suitable for all conditions. The D-30 has a maximum range of 15.4 kilometers, or over 21 km using RAP ammunition.
With its striking three-leg mounting, the D-30 can be rapidly traversed through 360 degrees. Although no longer manufactured in the nations of the former Soviet Union, the D-30 is still manufactured internationally and is in service in more than 60 countries' armed forces.
