AM 50

From Wikipedia, the free encyclopedia

AM 50 is a Czechoslovak, automatically launched assault bridge, that is used by combat engineers for crossing narrow obstacles such as rivers, canals, and ditches that are 10-12 meters wide.[1][2][3] It is based on a Tatra 813 8×8 truck.[1]

The AM 50 was developed for the Czechoslovak Army in the late 1960s. Today it is in use in the Czech Republic, Slovakia, India, Pakistan and Vietnam.

Development

[edit]

Work on the vehicle began in 1968 and went through 1969, with the vehicle entering service with the Czechoslovak People's Army in 1972.[1][3][4] Even though the original AM 50 variant was based on the Tatra 813 chassis, modern variants like the AM 50/70 EX are based on a modern Tatra 815-7 chassis.[4]
