65 years ago, on October 18, 1960, the prototype of the Be-12 anti-submarine amphibious aircraft first took to the skies in Taganrog.
The development of this turboprop amphibian, which was to replace the aging Be-6 flying boat in the Soviet naval aviation, began at the G.M. Beriev OKB. Unlike its predecessor, the Be-12 was designed as a platform for searching and destroying enemy submarines, equipped with an advanced radar station, a specialized search and targeting system, a magnetometer, as well as hydroacoustic buoys, depth charges, and torpedoes.
The designers needed to change their approach to design: previously, the main attention was paid to flight performance, and anti-submarine warfare equipment was considered secondary. Now, the primary task was to search for and destroy underwater targets.
In its general layout, the Be-12 resembled the Be-6, but surpassed it in size and weight, becoming the largest amphibious aircraft in the world at that time with a take-off weight of up to 36 tons. The estimated flight range was 3300 km, and the search duration at a distance of 600 km from the airfield was 3 hours. The maximum combat load reached 3 tons. Kuibyshev NK-4s were considered as power plants, but the choice ultimately fell on Zaporozhye AI-20Ds. The Be-12's equipment included three anchors and a water rudder for maneuvering afloat.
The search and targeting equipment included the Baku radio-hydroacoustic system, a search magnetometer, the Initiative-2B radar station, an automatic navigation device, and the Sirena-2 targeting and computing device.
The first flight of the Be-12 took place on October 18, 1960, in Taganrog. The tests, which lasted a little over a year, ended tragically on November 24, 1961: due to a crew error, the amphibious aircraft crashed, killing three crew members.
During the tests, a problem was revealed: the propeller blades were deformed by water splashes. The solution was to place the engine nacelles on the upper part of the wing, which was implemented on the second prototype of the Be-12, built by September 1962.
Serial production of the Be-12 was carried out in Taganrog from 1963 to 1973. A total of 143 aircraft were built in various modifications.
The Be-12 became the first Soviet aviation anti-submarine complex of special construction, adopted by naval aviation. Despite the complexity of control, pilots generally positively assessed this machine.
Some Be-12s are still in service with the Russian Navy's naval aviation.
