MAZ-7912/MAZ-7917 (Russian: МАЗ-7912/МАЗ-7917) is a Soviet and Russian army 14x12 transporter-erector-launcher designed and developed by the Minsk Automobile Plant (MAZ) in Belarus.
Developed primarily for use as a Topol ICBM mobile launcher, the 7912 model is similar in design to the MAZ-547A but has seven axles instead of six, including one dead axle.
In the mid-1980s, the MAZ-7917 variant was introduced, with an additional length of 1 m (3.3 ft) and crew cabins similar to the MAZ-7916.
At present, the 8-axle MZKT-79921 variant is used to carry the Topol M, Topol's replacement.
