ARMA 6×6 – Otokar/Tactical Wheeled Armored Combat Vehicle

ARMA 6×6 – Otokar/Tactical Wheeled Armored Combat Vehicle

ARMA is a modular wheeled armoured tactical vehicle designed and developed by Otokar in Turkey. The 6 x 6 platform vehicle was unveiled at the Eurosatory 2010 held in Paris in June 2010. The amphibious vehicle can carry a crew of 10 including commander, driver and eight soldiers.
The vehicle has agile mobility and provides a high level of mine and ballistic protection. The modular design allows for different configurations of armaments and mission equipment to meet modern battlefield requirements and other tactical missions. ARMA is expected to be more cost effective than its counterparts and have superior technical and tactical abilities.
The Koc Group Company, Otokar has also developed other armoured vehicles such as the Cobra and Kaya mine resistant troop carriers, for military use. Other armoured vehicles include a discreetly armoured station wagon, armoured patrol vehicles such as the Akrep, and the Otokar armoured internal security vehicle. It is also the prime contractor for the development of the Turkish Altay main battle tank.
The first export order for ARMA, worth $10.6m, was placed in December 2010. In June 2011, Otokar received a $63.2m export contract for ARMA vehicles.
ARMA armoured vehicle development
The ARMA 6×6 was developed for the Special Purpose Tactical Wheeled Armoured Vehicle programme (OMTTZA) for the Turkish Land Forces. Development of the tactical vehicle was started in 2007. The project was entirely funded by Otokar.
“ARMA is expected to be more cost effective than its counterparts.”
The company was responsible for the concept design, qualification, validation processes, detailed design, computer aided engineering studies and prototype testing phases of the vehicle. About 10,000km of running tests on prototypes have been conducted on different terrains.
ARMA 6×6 has been validated by Otokar R&D and is currently ready for mass production. Otokar reserves the intellectual rights for supplying and exporting ARMA to domestic and international markets. The 8×8 version of the ARMA family is currently under development.
Design and protection
The 6.4m x 2.7m x 2.2m ARMA has a modular design and can be configured to multi-wheels. The vehicle has a gross weight of 18,500kg and a payload capacity of 4,500kg. A spacious internal volume is created by placing the engine at the front of the vehicle. This internal layout can be used ergonomically and efficiently.
ARMA provides high anti-mine and ballistic protection due to its monocoque steel hull. The hull is also fully protected from biological and chemical threats. The dismounts seating of all the personnel are mounted on anti-mine seats. The 425mm ground clearance protects the crew from mines. Air conditioning is standard with the ARMA 6 x 6.
Armament
ARMA is armed with a 12.7mm machine gun mounted on a circle ring support. It can also be equipped with a range of manual and remote weapons stations.
ARMA family, due to its high payload capacities, allows integration with various types of mission equipment and weapon systems. ARMA supports weapon stations like open cupola, closed turret weapon station, remote control weapon station, medium and high caliber weapon systems.
Some of the weapon systems that can be integrated to ARMA are:
– Open Cupola with like 5.56 mm, 7.62 mm, 12.7 mm, 14.5 mm and 20 mm Machine Gun or Automatic Grenade Launcher
– Closed Turret with 7.62 mm, 12.7 mm
– Remote Control Weapon Station with 7.62 mm, 12.7 mm, 14.5 mm
– Medium Caliber Weapon Systems like 25 mm, 30 mm
– High Caliber Weapon Systems like 90 mm, 105 mm, 120 mm
– Anti Tank Missile Launcher Systems
A variety of weapon stations offering a wide range from the self-defence to direct fire support capabilities can be configured according to customer requirements.
Engine
The vehicle is powered by a 450hp water-cooled turbo diesel engine which uses F-34 or F-54 fuel. It drives the wheels through a single-speed transfer box and an automatic gearbox.
The engine also powers a 3.3kW converter and two 125Ah batteries which are included in the 24V DC electrical system on-board.
Mobility
ARMA has a power to weight ratio of 24.3hp/t and can travel at a maximum speed of 105km/h. It has geared hubs and a double wishbone-type independent hydro-pneumatic suspension system, as well as longitudinal and transverse differential locks.
“The ARMA can be configured in 6 x 4 or 6 x 6 mode drives based on the terrain.”
The tyres are able to run flat and a central inflation system is supplied as standard. These offer safety and a comfortable ride to the crew over difficult terrain. The ARMA can be configured in 6 x 4 or 6 x 6 mode drives based on the terrain.
The steerable front axles give ARMA a turning radius of 7.85m. The angle of approach and departure is 45°. The vehicle has a gradient of 60% and a 30% side-slope. It can also climb over obstacles of more than 60cm and cross a 1.2m wide trench.
The two hydraulically driven propellers and a pivot turn capability give ARMA the amphibious manoeuvrability in seas. The ARMA 6 x 6 in standard configuration is transportable by C130 aircraft
The engine is located at the right front of the vehicle, allowing a comparably high internal volume to be efficiently and ergonomically used. With this internal layout, all the personnel especially the commander can keep eye contact continuously among each other.
ARMA 6×6 is equipped with a 450hp powerful engine and proven driveline components to perform a superior mobility on all terrain conditions. Water-cooled turbo diesel engine capable of running on F-34 or F-54 fuel drives the wheels through an automatic gearbox and single-speed transfer box.
The independent suspension system enhanced with Run Flat Tires, built-in Central Tyres Inflation System (CTIS) and Anti-locking Brake System (ABS) improves ground mobility and ride comfort even over the roughest terrain. Vehicle’s mobility is further enhanced with longitudinal and transverse differential locks and the high power to weight ratio coupled with high ground clearance and approach/departure angles.
The ARMA 6×6 is the next generation product of Otokar developed by considering future mission requirements based on multi purpose wheeled vehicle platform. The ARMA 6×6 is developed, designed and manufactured by the Turkish Company Otokar.
ARMA 6×6 is the next generation product of Otokar developed by considering future mission requirements based on multi purpose wheeled vehicle platform.
ARMA vehicle development program was started in the date of 2007. Concept design, detailed design and engineering studies were completed within 2008. Mine blast effects, mobility performances, hydrostatic stability, driving comfort and other features were analized by using special engineering tools and simulations. First prototypes were produced at the beginning of 2009 and validation tests regarding trials, durability, driveline durability, reliability, hot and cold climate tests were performed succesfully. Furthermore, a mine blast mock-up was produced simultaneously and explosion tests were performed succesfully within 2010.
ARMA 6X6 was shown for the first time at the EUROSATORY held in Paris in June 2010 by which time development and company trials had been completed and Otokar was awarded with two contracts in the following year.
ARMA proved its performance and mobility under diverse conditons in trials and capability demonstration runs at different GCC countries.

Design
ARMA vehicles are designed by considering future and present mission requirements. Vehicle architecture allows the integration of a wide range of mission equipment and specific turret systems. Basic monocoque type body and double wall V-shaped hull structure provide exceptional protection to the crew against ballistic and mine threats. Modular armor kits providing different ballistic protection can be mounted rapidly to bolt on armour and additional protection against higher threats can be provided optionally.
ARMA 6X6 has an 18,500 kg gross weight and carries a driver, commander and eight personnel in its fully protected hull. ARMA 6×6 vehicles is transportable by rail, sea and air (C-130 and larger aircrafts).
ARMA 6×6 can provide a high level of protection against ballistic and mine threats by means of high hardness monocoque steel hull and all personnel is seated on individual mine protected seats. The crew compartment has firing ports and bullet proof observation windows together with two roof hatches and the crew members can rapidly enter and leave the vehicle via one door in the rear.
