Layout

The layout and positioning of equipment and parts in the BTR-90 is similar to those of the BTR-80 and BTR-80A. The commander and gunner are accommodated in a fighting compartment in the turret. This compartment also houses a BPKZ-42 gunner’s day/night sight and 1P-13 commander’s optical sight

The driver is located somewhat to the middle of the hull, just in front of the turret. The troop compartment is located behind the driver’s position and the turret. The engine compartment is at the rear of the hull.

Hatches are provided on the top of the turret and hull, and side doors are available on the middle of the vehicle. These are designed to allow quick dismounting and boarding of troops even while the vehicle is on the move.

The eight wheels are located as two sets, with two pairs at the front of the hull and two pairs at the rear. The side doors are located between these two sets of wheels. The two forward pairs of wheels are utilized with power steering

s from the water. The BTR-90 can be deployed by truck, rail and also by water and air transportation means.

Its hydro mechanical transmission helps to increase its maneuverability by providing different speeds to each side of the vehicle. This allows the BTR-90 to have a low turning radius of 6 m. When turning with only the front four wheels, it has a turning radius of 14 m. It can cross up to 2.1 m wide trenches and can negotiate 60% gradients, 30% side slopes and 0.8 m vertical steps.

The vehicle has an inner capacity of 12 cubic meters, and can carry a load of 7000 kg. An air conditioning

The turret can be traversed 360 degrees with an elevation range of -5 to +75 degrees. The vehicle’s weaponry allows it to engage targets at ranges up to 4 km. Helicopters and fortifications can be engaged at ranges up to 2.5 km.

In addition to the vehicle’s weapons, its occupants have the ability to fire their weapons through available firing ports and hatches, increasing its firepower.
