KrAZ 6130

In 1984-1985, the Central Research Institute “Petrel” designed and built an experienced self-propelled 152 mm howitzer 2S21 “MSTA-K” based on an enhanced chassis KrAZ CHR-3130, which received the index KrAZ-6130. All elements of the self-propelled howitzers were placed on a frame.

Because of difficults connected with the changes of KrAZ 6316, the Ministry of Defence came to a conclusion about inexpediency of further work according to this project. The only prototype was made.
