The Be-10 is an all-metal high-wing monoplane with the engines located beneath the wing roots and with splayed-out tailpipes. To minimize the risk of water ingestion, the engine air intakes are located on the forward fuselage section with spray fences on either side of the bow protecting the engines from water ingestion. The streamlined hull was fitted with a shallow single-step, sea rudder under the rear fuselage, 50° swept wings with marked anhedral and balance floats attached by short pylons at the wing-tips.
