152mm D-20

The 152mm D-20 is a Soviet-era towed howitzer-gun designed for both direct and indirect fire support. It is capable of firing a variety of ammunition, including high-explosive fragmentation, smoke, and illumination rounds.

Developed in the early 1950s by the OKB-9 design bureau under F. F. Petrov, the D-20 was created to replace the aging World War II-era ML-20 gun-howitzer and officially entered Soviet service in 1955. To streamline logistics, it was designed to share a common carriage with the 122mm D-74 field gun. The weapon saw extensive combat deployment during the Vietnam War, the Soviet-Afghan War, and the Iran-Iraq War, and it continues to be heavily utilized in the ongoing Russo-Ukrainian War. Today, the D-20 remains in active service with dozens of nations globally and has been widely produced under license, most notably in China as the Type 66.
