   The MTU-90 armored bridgelayer is designed to launch bridge for tanks and other combat vehicles across trenches and water obstacles in combat conditions. Sometimes it is referred as Gusenitsa-1. It was developed to replace the ageing MTU-20 and MTU-72 armored bridgelayers, based on the T-55 and T-72 tanks. Development of the MTU-90 is complete. Officially it was approved for production by the Russian Army in 1997. However it received no production orders. This bridgelayer is also being proposed for export customers.

   The MTU-90 is based on a modified T-90 main battle tank chassis. It is worth mentioning, that this MBT is in service with Russia. This bridgelayer is fitted with an MLC-50 load class three-part bridge, that is launched over the front of the chassis. The bridge has a total length of 25 meters, and covers a gap of 23 meters. The bridge can carry loads of up to 50 tonnes. The MTU-90 launches a bridge within 2-3 minutes.

   This armored bridgelayer offers high level of protection for the crew. Laying and recovering of the bridge is done by the crew without leaving the cabin. Developers claim, that it provides protection against armor-piercing, incendiary and hollow charge projectiles. Vehicle is fitted with NBC protection system for the crew, as well as automatic fire suppression system.

   The MTU-90 can launch a bridge in day/night and all weather conditions. This combat engineering vehicle is fitted with night driving equipment.

   This armored bridgelayer is powered by a V-84MS turbocharged diesel engine, developing 840 hp. The same engine was used on initial production T-90 main battle tanks. It seems that this armored bridgelayer is compatible with a deep wading kit.

   The MTU-90 is operationally compatible with the TMM-6 heavy mechanized bridge, based on the wheeled MZKT-7930 8x8 chassis. It can carry, lay, and retrieve a bridge section of the TMM-6.

   The MTU-90M is a recent improved version. It has a shorter bridge and can span a gap of 19 m. Despite the shorter length the bridge can carry loads up to 60 t, opposed to 50 t of the original bridgelayer. The MTU-90M was accepted to service with the Russian Army in 2013. Azerbaijan ordered undisclosed number of these bridgelayers. Deliveries are expected in 2014.
