The success of the Be-12 did not translate into Beriev's next designs. In the autumn of 1962, the Bureau began a design for a heavy load, long range seaplane intended solely for anti-submarine warfare. No name was given to this new project, which would have carried four Kuznetsov NK12-M turboprop engines, supplemented by two Lyulka AL7-PB jet engines for short take-off assistance. Although the project never made it to the design table, the plane's profile became the cornerstone of the massive Project LL-600 [Letayushchaya Lodka = flying boat] effort, which called for the seaplane to shift its profile from a pure anti-submarine/reconnaissance platform to a bomber or even a commercial airliner profile. This proved too ambitious, and was cancelled by the middle of the 1960s.
By the winter of 1963, preliminary studies were made in the Soviet Union regarding the feasibility of developing a long range, heavy payload seaplane capable of operating equally from water and land. In fact, the studies suggested a type of Short Take-Off air platform. A huge leap in technology, but one that Beriev's engineering team believes that it could accomplish.
The Be-26 ocean amphibian PLO [ie, ASW] aircraft was developed in the OKB in early 1963. It was conceived as an aircraft far area (ocean) PLO capable based at airfields. At that time it was thought that from the very beginning of the war fixed airfields with concrete runway will be immediately removed from the damaged nuclear attack the enemy.
Aircraft designers designs were accessible to the home afloat, as well as short take-off, to ensure that in the composition of the power plant but two flight engine NK-12 engines installed on 16 lifting TRD RD-36-35 in clusters around the wing root leading and trailing edges. To expand and increase time finding submarines provided an opportunity to refuel Be-26 from surface ships and submarines at sea or air tankers, extending the aircraft's operational range.
The plane was a flying boat amphibian of normal aerodynamic scheme with a direct high-wing. In the bow of the aircraft was sealed cabin crew, a compartment for discharged RGB, and in the middle of the boat a compartment for combat stores. The three point landing gear consisted of a strut in the bow of the boat, and four main stands - in a special gondola in the middle of the wing, like the Tu-134. The power plant - two TVD MK-12MV capacity of 15 thousand hp on pylons over the wing. For short take-off used 16 aerial TRD RD-36 with a thrust of 2500 kg, were set in the fairing at the root of the wing, with eight units on each side. The weapons, combat load (torpedoes, depth bombs, naval mines, RGB), were located inside the fuselage.
The numbers that Beriev's team began to put out about the 26 capability profile were impressive. The seaplane would operate at a top service ceiling of 42,500 ft with a top operational range of 7,275 nautical miles. Notwithstanding these impressive figures, the Be-26 proved to be too technical challenging and the program never made it out of the drawing board.
