Description

The OTTER also called Armoured Amphibious Assault Bridge (AAAB) is a bridge and ferry system designed for the Turkish Armed Forces' fast and safe transport through the rivers on the battlefield. The vehicle is designed and manufactured by the Turkish Company FNSS. As a Turkish designed and developed amphibious bridge system in Turkey, the OTTER system has some additional unique specifications for a bridge and ferry system. It can carry 4 ramps on a single system. The OTTER system also has a standard anchoring system (both emergency and land anchoring systems), ballistic protection, and easy fault detection with CAN system. The OTTER system can also be used in natural disasters such as floods. Being the only 8x8 vehicle in its class in the market today, the OTTER has unprecedented redundancy, operational capability in soft soil, cross-country mobility and amphibious performance. Four training sets of Amphibious Assault Bridge, delivered to Turkish Land Forces Command in September 2011, were subjected to challenging durability tests for land and sea tasks for 10 months and succeeded in such tests. Being under the mass production phase, 52 OTTER vehicles are planned to be delivered to the Turkish Land Forces Command. In May 2019, it was announced that Turkey and South Korea are combining their strengths in order to meet the Republic of Korea (RoK) Army's wet gap crossing system requirement. FNSS of Turkey and Hyundai-Rotem of RoK team up to offer the OTTER Armoured Amphibious Assault Bridge (AAAB) vehicles for the evaluation of the South Korean Ministry of National Defense (MND), RoK.

Technical Data

Design and Protection
The FNSS OTTER or AAAB Armoured Amphibious Assault Bridge is operated by a crew of three. A crew cabin is available at the front of the vehicle. The hull and crew cabin are made of welded aluminum. The crew cabin provides protection against the firing of small arms and artillery shell splinters. When traveling the side elements of the bridge are on top of the vehicle and are swung through 180 degrees to either side when deployed with the other elements being fitted using the onboard crane.

Mobility
For its displacement in road conditions, the FNSS OTTER is designed using an 8x8 chassis based on the PARS 8x8 armored vehicle personnel carrier. The vehicle is motorized with a German Deutz turbocharged diesel engine, developing 522 hp, coupled to a fully automatic transmission with six forward and one reverse gears, and a two speed transfer case. The OTTER can reach a maximum road speed of 76 km/h with a maximum road range of 600 km. With its diesel engine, automatic transmission, pneumatic suspension and hydraulic brake system, the OTTER system can climb up to 50% gradient, move on a 30% side slope and cross a trench of 2m maximum. The OTTER system has two water pump jets that provide the water operations and 360° movements in the water. The system can operate in water currents up to 2.5m/s (10km/h).
Accessories
The FNSS OTTER, different from similar systems in the market, has an 8x8 drive system with a central tire inflation system. For the safety issues, the OTTER system has a self-recovery winch, an automatic fire suppression system, a fixed fire extinguishing system, portable fire extinguishers, and positive pressure NBC system. The standard equipment of the FNSS OTTER includes also Anti-lock Braking System (ABS), Traction Control (CT), land and emergency anchoring systems, radio intercom systems, onboard diagnostics system, and automatic bilge pumps with manual override.
Accessories
As a ferry, the FNSS OTTER system can transport MLC 21 tracked vehicles. By deploying the ramps, which are carried by a hydraulic crane, and joining two systems, the MLC70 T vehicle can be transported. In the road position, the crane is on the centerline of the vehicle. Two OTTER systems can be coupled together to form a pontoon bridge and can transport an MLC85 T vehicle. By coupling three systems ramp to ramp, up to MLC120 W vehicle can be transported over a wet gaps. Eight OTTER systems can be combined together ramp to ramp to construct a 100 m long bridge in around 10 minutes that is capable of carrying MLC85 T & MLC120 W vehicles. For specific missions, numerous OTTERs can be coupled together to cross wider distances.
