FNSS SAMUR Amphibious Assault Bridge in IDEF 2011

joint Turkish Land Forces Command (TLFC) and FNSS Savunma Sistemleri contractor team is carrying out acceptance and user trials of the first completed Amphibious Assault Bridge (AAB) system.

Under a contract awarded in 2007, FNSS is to supply four operational AABs and one training system to the TLFC, due for delivery by the end of 2012 or early 2013. Development of the first system was completed earlier this year.

Each operational AAB consists of 12 units which, when fully deployed, will enable soldiers and vehicles to span a river up to 150 m wide. The training system will only comprise four units.

The AAB weighs 36.5 tonnes (Military Load Class 35 - MLC 35); a fully enclosed cab with appliqué armour provides the crew of three with protection from small-arms fire and shell splinters. An NBC (nuclear, biological and chemical) system is also installed.

While in travelling mode the side elements of the bridge sit on top of the AAB. When deployed with the other elements they are swung vertically through 180 degrees on each side.

When being used as a bridge the AAB has a maximum single load of MLC 70 for tracked vehicles and MLC 100 for wheeled vehicles.

The AAB can also be used as a ferry, for which two units coupled together have a maximum single load of MLC 70 for tracked vehicles. Three joined-up units have a maximum single load of MLC 100 for wheeled vehicles.

The vehicle is powered by a diesel engine developing 530 hp coupled to a fully automatic transmission, with six forward gears, one reverse gear and a two-speed transfer case. This gives a maximum road speed of 50 km/h and a minimum operating range of 600 km.

Tyres are 16.00 x R20 heavy-duty with run-flat inserts. Differential and longitudinal locks are also provided.

The ride height can be controlled electronically for road or cross-country travel, but the suspension is retracted for amphibious use to reduce drag. Ground clearance can be adjusted from zero to 0.65 m.

The AAB also features all-wheel steering, with a central tyre inflation system, traction control, anti-lock braking system and hydraulic winch. Land and emergency anchoring systems are standard equipment.

A radio and vehicle intercom system is fitted, as are an onboard diagnostic system and a distributed electronics architecture.

While afloat the vehicle is propelled by two water pump jets, achieving a maximum speed of 10 km/h. Each water pump jet can be traversed through 360 degrees.

The AAB can be deployed in water currents with speeds up to 2.5 m/s. Automatic bilge pumps are provided, with manual override.
