The Beriev Be-8 (known to the USAF/DoD as "Type 33" and by NATO as "Mole") was created by the Soviet Beriev Aircraft Company in 1947. This amphibious aircraft, intended for passenger and liaison duties, shared a resemblance in configuration with the Beriev Be-4 but was distinguished by its larger size and increased weight. Featuring a single-engine mounted on a parasol wing, it included retractable landing gear and utilized an engine exhaust heat exchanger to provide heating for both the cockpit and passenger compartments. Designed primarily for civilian applications, the Be-8 was unarmed. Its maiden flight took place on 3 December 1947, demonstrating commendable performance; one of the two prototypes was later displayed during the 1951 Soviet Aviation Day event in Tushino.
One of the prototypes was equipped with hydrofoils developed by TsAGI, attached to the landing gear struts. These hydrofoils were intended to lift the aircraft above the water surface prior to achieving aerodynamic lift, facilitating easier takeoffs and minimizing hull damage from wave impact. However, this system also introduced additional drag, which resulted in a decreased top speed. Due to technical challenges, retractable hydrofoils were never realized, and the concept remained experimental without entering operational service.
