KOR-2 (BE-4) - deck catapult flying boat (near the sea scout), developed in 1941 under the leadership of OKB Beriev. Tested in the years 1942-1942, in 1943-1945 was produced in small batches.
KOR-2 was intended primarily for close-in offshore exploration, adjust fire naval and coastal artillery, as well as the protection of heavy warships from enemy submarines, anti-submarine search, combat warships and small boats. Adopted by the time adopted the KOR-1 is absolutely not satisfied sailors.Design.
Seaplane KOR-2 - boat-metal monoplane, made the scheme a flying boat with a wing-type parasol pole and short struts. As the power plant on the experimental KOR-2 was chosen as single-row radial engine air-cooled M-63 capacity of 1100 hp a tractor propeller. The nacelle, which is inscribed in the center-wing fuel tanks and oil tank are located. Dvuhlonzheronnoe wing design with stressed skin. Console of the wing can easily fold and unfold. The installation angle of the wing 5 degrees. The front wing has a kind of "reverse gull" and is on the pylon, which is structurally integral with the boat. To reduce the landing speed set guards Schrenk. Boat dvuhredannaya. Redan first wedge-shaped in plan, and the second - a curved. To provide lateral stability to the aircraft have underwing floats, each attached by two streamlined struts to the console.
The crew consisted of the pilot and the navigator, and in the cockpit can be installed removable second set of control plane. Armament consisted of one fixed 7.62-mm machine gun ShKAS in the bow of the boat, such as the machine gun on the turret MV-5, located in the middle of the boat, and 200 kg bombs.
In December 1940, in accordance with the order of NCAP number 704 "About renaming of combat aircraft" KOR-2 was designated Be-4.January 21, 1941 completed factory testing, which led to the most favorable conclusions on the flying boat.
August 11, 1941 to complete the construction of the first production aircraft (serial №28801). In contrast to the experimental machines, equipped with its less powerful, but has a great resource engine M-62 take-off power of 1000 hp and rated 850 hp the first boundary altitude. Screw - three-bladed VISH-105-62 or AB-24. In addition, some improvements carried out construction and equipment. In particular, the airline established a mechanism for emergency relief canopy pilot bronespinku, radio RSMR-3 was replaced by bis RSBM, and the camera AFA-27 AFA-27T. This machine was destined to perform a total of 6 flights. September 9, with good sunny weather and a full calm sun glare led to the mirror effect, and fly a plane NP Kotyakovu was very difficult to determine the landing distance to the water. As a result, the touch occurred at a high speed, the aircraft received substantial damage and quickly went to the bottom. Along with him drowned Military Technician 1 st rank Sukachev, and pilot and engineer Beria KB Morozov managed to escape. However, in an emergency act it was emphasized the general opinion that "the car is good."
September 14 Radelet raised in the air a second serial Be-4 (№28802). Altogether during the test, which lasted until October 10, it was performed 49 operations with a total touch 10 hours 3 min. The aerobatic flight evaluation noted that the "Be-4 is simple in piloting the machine, it is designed for semi-skilled pilot, and the aircraft taxiing perfectly manageable due to effective water wheel"
After the evacuation of factories Be-4 produced at two factories - № 288 in Omsk, and number 477 in Krasnoyarsk.
Weapons collected in Omsk cars was strengthened: ESP ShKAS replaced by two 12.7 mm machine guns UBC, the number of under-wing bomb racks have increased to four, and now the aircraft could lift 400 kg bombs (4 explosive FAB-100 or 4 100 anti PLAB). There were also partially modified the design of the boat and the unit number of systems.
Combat application. In the Black Sea Be-4 were used as short sea scouts, systematically looking 40-mile coastal zone, and performing tasks in the areas of antisubmarine naval bases. Several times Be-4 met in the air with the German flying boats BV-138 and the Do-24, sometimes it comes to the shooting, but they duel passed without consequences for both sides. With the change in the general situation at the front in our favor, Be-4 came on board warships. On the cruiser "Molotov" T-bills by the decision №4093 of September 12, 1943 established the modernized catapult LC-1A. In Batumi in August 1944 with her ran blanks, and the following month began Novorossiysk acceptance tests. In the act of October 24, 1944 noted that "the catapult launches multiple proven Be-4 and" Spitfire ", works perfectly and can be allowed to operate." In June 1944, the Black Sea Fleet was formed 24th Squadron separate naval aviation, of which, in addition to the Be-4, entered fighter "Spitfire» Mk.VB. In July 1945 as part of the squadron, there were 8 Be-4.
In the Northern Fleet, practically throughout the war did not have ships larger destroyer, the Be-4 did not serve. However, in the Arctic to war seaplanes Beriev still had. In 1943, German submarines began active operations in the Soviet Arctic routes. To deal with them at the Northern Party White Sea Flotilla was not strong enough, therefore, among other measures, it was decided to send to. Dixon two Be-4. The choice fell on the car with №№28811 and 28812, where the number of polar aviation and received civil registration of the USSR and the Soviet Union-NZZO-N331 respectively. First piloted V. Malkov, the second - MV Teiman. Aircraft flew from Krasnoyarsk to Dickson and August 2, 1943 began antisubmarine patrols. As the weapons used anti-bomb PLAB-100. The only combat collision occurred on August 28. After a German submarine sank 20 miles off Cape Sterligov transport "Dixon" Be-4 probombili area. An attack crews were not observed. In late September, sharply colder, it started freezing, forcing overtake seaplanes back to Krasnoyarsk. By then flown NZZO Arctic 35 h 15 min and N331 - 31 h 20 min. In the Baltic Be-4 appeared in 1944, when the first nine aircraft were part of the 29th separate reconnaissance squadron. In early 1945 it was registered 10 Be-4: №№ 4770205, 4770301, 4770302, 4770303, 4770305, 4770401, 4770402, 4770403, 4770404, 4 770405. The objectives of the seaplane was conducting ASW search and rescue crews downed aircraft. For example, the July 22, 1944 after a strike at the German ship made an emergency landing in the Gulf of Il-2 from the 8 th Guards Assault Regiment 11 th Attack Air Division. The aircraft sank quickly and the pilot and gunner Stryzhak Kuznetsov moved to a lifeboat and were later taken out of the Be-4 taking off from Mount gidroaerodroma Valdai.
On January 1, 1945 as part of the 115th Aviation Regiment blizhnerazvedyvatelnogo Maritime Force Pacific Fleet including four Be-4 (№№28808, 28809, 4770201 and 4770203). In the fighting against Japan, they did not participate, but after the war confirmed his appointment as a naval intelligence flight with catapults Pacific cruisers "Kalinin" and "Kaganovich."
Interestingly, in May 1945 the People's Commissar of the Navy issued an order on the establishment of additional remuneration flight and technical staff for starting from a catapult. For the first such rise of the pilot was supposed to 150 rubles., For all subsequent - 75 rubles. Navigator pays a premium of 75% of the remuneration of the pilot and equipment - 50%. If the pilot carried out a control of the aircraft circled, just joined the ship from the factory or after major repairs, owed 500 rubles.
In the summer of 1946, "Kaganovich" and "Kalinin" Be-tested in 4 №4770702 accelerated version. The plane was piloted by test pilot to Mr. VFSokolov. To ensure the correct position of the pilot and navigator in the workplace during the launch of their chairs they supplied armrests, headrests and glides. From 3 to 12 July Catapult LC-2A cruiser "Kalinin" run completed 32 pigs and 13 starts of aircraft parked the ship at different wind force and with different flight weight. 16-28 August, the cruiser "Kaganovich" (Catapult ZK-2B) had a 5 starts of the aircraft (one - with a takeoff weight of 3200 kg and four - with 3345 kg) on the move at the speed of the ship bailout of 130 km / h and maximum acceleration to 4, 5 d. It was noted that all the ups were normal, with no "sagging" and "swelling" of the aircraft and the Be-4 accelerated version can be piloted secondary qualifications.
To sum up, I must say that the Be-4 as compared to its predecessor the CDF-1 was a significant step forward. This flying boat was quite modern, nautical, comparable in flight characteristics with their foreign counterparts scout ship. Be-4 was the only domestic seaplane, standard builds in the war years. But the ships created for the "great sea and ocean-going fleet," which did not have time to get off the stocks before the war, Be-4 actually lost his job. Most was short and his postwar career. With the advent of warships radar reconnaissance aircraft ejection have lost their value, and in 1947 dismantled the catapults on all cruisers.
From 1941 to 1945, it was built 44 aircraft.
