Tatra 815-7

Tatra 817 is a development of T-815 chassis, aimed for transportability by the most common NATO transport aircraft C-130 Hercules as well as ability to easily add armor plates for protection. Tatra took the engines and transmissions of the 815-6 model, the chassis T-815 has been modified and a completely new cab has been developed.

In 2004 a prototype of model 4×4 appeared at Eurosatory and other defence and security trade shows. Several other prototypes were later built ranging from 6x6 to 10x10. The cabin is all-metal, tiltable, its construction allows easy additional armoring in various degrees of ballistic protection. Cab tightness allows the use of overpressure filtering.

Tatra 817 standard trucks serve in the Army of the Czech Republic and the Slovak Armed Forces, while 817 chassis with specialist superstructures (e.g. artillery cannon, rocket launcher, armored recovery vehicle, etc.) serve also in many other countries. It is also used in the civilian sector, especially in applications that particularly benefit from the truck's lower center of gravity, such as mobile cranes and fire trucks.[2]

T817 uses traditional Tatra backbone tube chassis instead of the more usual truck ladder frame. The chassis is designed primarily for off-road application, which gives it a comparative advantage over primarily road-intended trucks that were modified for offroad use.[4]

As such, Tatra Czech manufactured T817 chassis is being used as basis for other specialist vehicles made in a number of countries.
