Family: UR. Country: Russia. Status: Hardware. Other Designations: Proton / Block DM-2. Library of Congress Designation: D-1e. Department of Defence Designation: SL-12. Article Number: 8K82K. Manufacturer's Designation: UR-500K.

This improved four stage version uses the Block DM / 11S86 fourth stage, which has its own guidance unit. This reduces payload but does not require the spacecraft's guidance system to provide steering commands to booster. Replaced the original Block DM / 11S86 version from 1982 to 1995. Used for launch of Glonass navigation satellites into medium earth orbit; and launch of Luch, Ekran-M, Potok, Raduga, Gorizont, Raduga-1, Elektro, and Gals communications satellites into geosynchronous orbit.
