The Soviet Beriev KOR-1 ( Russian Бериев КОР-1 , also: Be-2 , Бе-2) is a catapults and suitable for sea reconnaissance aircraft and solved in this function mid-1930s, the biplane - flying boat KR-1 from. KOR stands for Korabelni raswedtschik (Russian Корабелний разведчик), boat scout.


It is one of the few Soviet seaplanes that was designed exclusively as a floatplane from the beginning of its development. The KOR-1 was designed in 1934/35, the prototype flew for the first time in 1936, the construction of a small series began from 1937 and the introduction to the airborne reconnaissance squadrons from 1938. Since the KOR-1 was supposed to take on light combat tasks in addition to its main purpose, it was capable of diving executed; Their offensive armament served the same purpose.

At the beginning of the war against Germany , it was used to defend the Black Sea coast and was even used for attack aircraft missions, with some also receiving a temporary wheeled landing gear and operating from land. Some KOR-1s were used as aircraft on large surface ships, such as the heavy cruisers Maxim Gorki and Kirow . The particular strengths of the KOR-1 were its good climbing performance and above-average maneuverability. It was replaced by the Be-4 (KOR-2) .

technical description

The KOR-1 is a biplane in mixed construction with a central main float under the hull. The frame for the fuselage and supporting structure is made of light metal and is partly covered with fabric (wing and tail unit over everything, middle of the fuselage and stern), and partly covered with light metal (bow and underside of the fuselage). The single-spar wings of the same wing span are connected to each other and to the fuselage by double T-handles and braced and can be folded for on-board operation. The tail unit is of normal construction and braced. The floating mechanism, consisting of the single-stage , keeled main float with a retractable oar and two non-stepped support floats at the wing tips, is made of metal and is braced and braced.
