In Germany, Rheinmetall introduced the new KF51 Panther tank. For the first time since World War II, the tank is again called "Panther". There is little information about the tank, it is known that it has a new 130-mm cannon and a coaxial 12.7-mm machine gun. The new gun was introduced back in 2016, in response to information about the Russian Armata tank. For the first time in German tank building, the gun has a full-fledged automatic loader, where 20 shells are loaded, but after they finish, the rest must be loaded manually. On the KF51 Panther tank, you can install a remote-controlled machine gun of 7.62 mm caliber. The principle of "transparent armor" is implemented in the vehicle, the crew sees the situation around the tank with the help of screens. The tower can integrate a system for launching HERO 120 kamikaze drones and reconnaissance UAVs. The tank has passive protection and reactive protection built into the body, like the "Armata", as well as some kind of "active protection". The crew of the tank is 3 people and it is not placed in an armored capsule like the "Armata", but classically in the tower, the fourth crew member can control the drones. The weight of the KF51 Panther tank is 59 tons, the cruising range on one gas station is 500 kilometers, the price is unknown. The KF51 Panther tank has not yet been put into mass production.
