The RPD was first developed in 1943 and it was designed by Vasily Degtyaryov. The RPD itself was designed to replace the older DP LMG and become the new standard squad automatic weapon for the Red Army. The RPD did not see mass production until the early 1950s, but a small amount were produced during World War II. Still, it is unknown whether any were actually delivered to Red Army troops. The RPD was used extensively after World War II by the Soviet Union, the North Vietnamese, etc. However, in the 1960s, in Soviet service, the RPD was replaced by the Kalashnikov-Designed RPK.
