assenger/liaison amphibian with layout similar to the Be-4 but substantially larger and heavier. It was a single-engine parasol with wing installed on thin pylon and pair of short struts. Compared to the Be-4, Be-8 was equipped with retractable landing gear (taildragger scheme), pilot and passenger cabins had heating system utilizing engine heat. Aircraft had de-icing system, carried wealth of navigation, radio- and photo, dual flight controls (wires) and electromechanically operated landing flaps. Be-8 was intended as a civil aircraft and carried no armament.
Be-8 was built in 1947 and trials started on December 3, demonstrating good performance. Two experimental aircraft were built, one was demonstrated during 1951 Soviet Aviation Day at Tushino.

One of Be-8 was equipped with hydrofoils, developed at TsAGI. "Underwater Wings" were installed on landing gear struts and pushed aircraft from the water well before it could be done by the wing lift force. As a result, takeoff was much easier and imposed less punishment on the hull from the waves. Despite very effective during takeoff hydrofoils had negative impact on flight speed. Construction of retractable hydrofoils was not ready, and the concept did not find practical applications. There it is now...

Be-8 is sometimes reported to have the name 'Mail' assigned (which was the used on Be-12) and being a jet-engined version of the Be-6 'Madge' (possibly erroneously referring to the R-1)
