The Beriev Be-10, also known as Izdelye M, (NATO reporting name: Mallow) was a
twin engined, turbojet powered, flying-boat, patrol bomber built by the Soviet
Union from 1955. The Be-10 is sometimes referred to as the M-10, though this
designation is believed to apply only to the modified Be-10 that established 12
FAI world records in 1961, Bort no. 40 Yellow, still holding class records for
speed and altitude.
The Be-10 was designed in response to Council of Ministers of the Soviet Union
directive No.2622-1105ss which called for a turbojet powered flying boat for
open-sea reconnaissance, bombing, torpedo attack and mine-laying. Stipulated
performance was to include a maximum speed of 950 to 1,000 km/h (590 to 621 mph)
and the ability to operate in wave heights of 1.5 m (5 ft) at wind speeds up to
20 m/s (45 mph) with submission for state acceptance trials in November 1955.
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
floats attached by short pylons at the wing-tips.
surfaces were Ailerons on each wing, a rudder on the fin and elevators on the
tail-planes. The fuselage was a two step design with a high length to beam ratio
to improve rough water handling, v-section planing bottom, two steps and was
divided into nine water-tight compartments the forward and rear compartments
being pressurised. Engine nacelles for the Lyul'ka AL-7F engines were attached
to the fuselage sides under the wing centre-section.
The original design showed some weaknesses in the seaworthiness and had to be
modified; after modification the Be-10 was seaworthy up to a wave height of 1.2
meters (4 feet) and able to fly with wind speeds up to (57.6 km/hr; 36 mph) from
water or land.

Operational use of the Be-10 began when the 2nd Squadron of the 977th
Independent Naval Long-range Reconnaissance Air Regiment (977th OMDRAP) started
replacing its Beriev Be-6 flying boats with Be-10 aircraft. This squadron and
the 1st Squadron of the 977th OMDRAP became the only operators of the Be-10,
operating from a naval base at Lake Donuzlav on the Crimean peninsula
The first public appearance of the Be-10 was when four aircraft flew over the
1961 Aviation Day air display at Tushino, giving the impression that the Be-10
was already in service. However, the Be-10 proved to be difficult to fly and
there were several accidents. The Be-10 suffered from metal fatigue due to the
stress on the airframe from the high-speed takeoffs and landings, together with
corrosion. The Be-10 was removed from service in 1968, and was replaced by the
turboprop-powered Be-12, which was easier to operate and had better endurance.
