The Kamov Ka-50 Black Shark (NATO reporting name: "Hokum A") is a single-seat Russian attack helicopter with the distinctive coaxial rotor system of the Kamov design bureau. It was designed in the 1980s and adopted for service in the Russian army in 1995. It is currently manufactured by the Progress company of Arseniev. During the late-1990s, Kamov and Israeli Air Industries developed a tandem-seat cockpit version, the Kamov Ka-50-2 Erdogan (Turkish for "Born Warrior"), to compete in Turkey's attack helicopter competition. Kamov later designed another two-seat variant, the Kamov Ka-52 Alligator (NATO reporting name: "Hokum B"). The aircraft carries a substantial load of weapons in four external hardpoints under the stub wings plus two on the wingtips, a total of some 2,300 kg depending on the mix. The main armament are the twelve laser-guided Vikhr anti-tank missiles with a maximum range of some 10 km. The laser guidance is reported to be virtually jam-proof and the system features automatic guidance to target enabling evasive movement immediately after missile launch. The fire control system automatically shares all target information among the four Black Sharks of a typical flight in real time, allowing one helicopter to engage a target spotted by another, and the system also can input target information from ground-based forward scouts with man-portable target designation gear. The integrated 30mm cannon is semi-rigidly fixed on the helicopter's side, movable only slightly in elevation and azimuth. The aircraft's agility allows the weapon control system to turn (the entire helicopter and) the cannon at the target acquired in the pilot's helmet sight about as fast as the cannon turret of the Apache or the Mi-28 turns. The semi-rigid mounting improves the cannon's accuracy, giving the 30mm a longer practical range and better hit ratio at medium ranges than with a free-turning turret mount.-----Brught military song about Border Guards Music: G.
