The '''Tatra 815-7''' (also known as '''Tatra 817''', '''T817''' or '''Tatra Force''') is a heavy army logistics vehicle made by the [[Place:Czech Republic|Czech]] company [[Company:Tatra|Tatra]] produced since 2007. T817 is primarily intended for military operators and for specialist roles in civilian sector (with [[Engineering:Tatra 158 Phoenix|Tatra 158 Phoenix]] being the company's primary general-purpose truck for civilian sector). The truck is made primarily with axle variations of [[Engineering:Four-wheel drive|4×4]], [[Engineering:Six-wheel drive|6×6]], [[Engineering:Eight-wheel drive|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 [[Engineering:Lockheed C-130 Hercules|C-130 Hercules]] transportable military truck. The prototype was based on Tatra's traditional backbone chassis, with a water cooled [[Company:Cummins|Cummins]] engine and a ZF transmission.<ref name="hist">https://www.tatra.cz/o-spolecnosti/historie-tatry/historie-vyroby/</ref> 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 [[Engineering:Tatra 815|Tatra 815]], in order to undergo a simplified [[Social:Homologation|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.<ref name="hist" />

===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 [[Engineering:Tatra 158 Phoenix|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.<ref name="armnov">https://www.armadninoviny.cz/koprivnicka-tatra-predstavila-novou-generaci-modelove-rady-tatra-force.html</ref>

===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.<ref name="armnov" /> This new version offers a modernized cabin coupled with a modified position of the engine.<ref name="armnov" /> The new four-door cabin offers enough space for up to eight crewmen in three rows.<ref name="armnov" />

Tatra air-cooled V8 engines were also modernized, offering up to 340kW of power output. With the third generation, Tatra re-introduced  its previously discontinued air-cooled V12 engine, offering up to 440 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.<ref name="armnov" />

==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 [[Engineering:Fire engine|fire trucks]].<ref>{{cite news |title=Tatra Trucks loni dodala 1186 vozů.

==T817 chassis military applications==
The T817 uses a traditional Tatra [[Engineering:Backbone chassis|backbone tube chassis]] instead of the more typical truck [[Engineering:Vehicle frame#Ladder frame|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.<ref>{{cite web | url=https://www.defence-and-security.com/features/featureidex-2021---tatra-trucks-fully-loaded-4x4-to-16x16-complete-off-road-performance-8548309/ | title=IDEX 2021 - TATRA TRUCKS: Fully Loaded, 4x4 to 16x16, complete off-road performance - Defence & Security Systems International }}</ref>

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