Tatra 815-7

The Tatra 815-7 (also known as Tatra 817, T817 or Tatra Force) is a heavy army logistics vehicle made by the Czech company Tatra produced since 2007. T817 is primarily intended for military operators and for specialist roles in civilian sector (with Tatra 158 Phoenix being the company's primary general-purpose truck for civilian sector). The truck is made primarily with axle variations of 4×4, 6×6, 8×8 and 10×10. Other chassis variants up to 16x16 are also available.

History

First generation (2007–2016)

In 2004, Tatra introduced a prototype of the new ''817'' line of trucks after presenting a 4x4 NATO C-130 Hercules transportable military truck. The prototype was based on Tatra's traditional backbone chassis, with a water cooled Cummins engine and a ZF transmission. Even though the truck was being developed as an entirely new line, the company decided to formally introduce it to the market under the ''815-7'' designation as a new version of the Tatra 815, in order to undergo a simplified homologation process.

The Tatra 817 entered serial production in 2007. This serial version offered a large extent of modularity for chassis components, engines (air-cooled Tatra or water-cooled Cummins), transmissions (manual, semi-automatic, automatic), and a cabin that allows the simple addition of armor components in line with the STANAG 4569 standard. Cab tightness allowed for the use of overpressure filtering.

While originally intended for military operators, the truck has been offered to civilian customers since 2010, particularly for specialist purposes such as firefighting.

Second generation (2016–2023)

The second generation T817 was introduced in 2016. Its cabin was modernized and a four-door long cab version was introduced. The chassis was modernized and unified with the Tatra 158 Phoenix. Apart from a standard cab, the truck was now offered with a high level of protection of armored cabs produced by sister company Tatra Defence Vehicles.

Third generation (since 2023)

In May 2023, at the PYROS expo, the third generation T817 was introduced when two fire trucks were presented to the public. This new version offers a modernized cabin coupled with a modified position of the engine. The new four-door cabin offers enough space for up to eight crewmen in three rows.

Tatra air-cooled V8 engines were also modernized, offering up to 368 kW of power output. With the third generation, Tatra re-introduced its previously discontinued air-cooled V12 engine, offering up to 515 kW of power output. The third generation continues to be available with a line of water-cooled Cummins engines. At the time of introduction, a hydrogen powered version was under development.

Users

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.

T817 chassis military applications

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

As such, Tatra Czech manufactured the T817 chassis to be used as the basis of other specialist vehicles made in a number of countries.
