The MZKT-79221 (Russian: МЗКТ-79221) is a Soviet and Russian army 16x16 transporter-erector-launcher designed and developed by the MZKT in Belarus.
Developed primarily for use as a RT-2PM2 Topol-M ICBM mobile launcher, the 79221 model is similar to the MAZ-7917 but has eight axles instead of seven. It is powered by a YaMZ-847.1 (800 horsepower) V12 diesel engine.[1]
