A updated version of new Russian K-16 Bumerang Armored Personnel Carrier (APC) and K-17 Bumerang  Infantry Fighting Vehicle (IFV) were seen in footage released on July 30, by Roman Bachkova.
Currently, the updated version has been submitted for test at proving ground in Smolino (Nizhny Novgorod Region).
The update model of  a new-generation Russian armored personnel carrier have some external changes in the design. This new armored personnel carrier has a crew of 3, including commander, gunner and driver. It can carry 9 soldiers. Firing ports for the troops were deleted in order not to compromise armor protection.
Vehicle has a V-shaped hull that deflects mine blasts away. As usually this vehicle is fitted with NBC protection and automatic fire suppression systems. It has been reported that the Bumerang can be fitted with active protection system.
The Bumerang (Boomerang) is a new-generation Russian armored personnel carrier and  infantry fighting vehicle. The Bumerang is a clean sheet design. It is not based on any previous Russian armored vehicle. Actually it resembles Western designs. A number of components and subsystems of the Bumerang are interchangeable with the Kurganets family of tracked armored vehicles.
Engine of the Bumerang is located at the front of the hull. Troops enter and leave the new vehicle via rear power-operated ramp with integral doors. It is worth mentioning that a rear-mounted engine of the BTR series APCs was a significant drawback, as troops had to leave the vehicle via side doors. Cramped side entry and exit hatches are even worse on BTR-70 APCs, which is still in service with the Russian Army. If such vehicles are ambushed, troops usually have to leave it under direct enemy fire.
