The A-40 is a jet-engined
flying boatpatrol bomber of all-metal construction with the engines located above the
wing roots, atop each of the main landing gear nacelles at the rear of each wing root. The
swept wings,
set high on the fuselage, have a marked
anhedral angle, with balance
floats attached by short pylons directly under each wingtip.
Development
The
maiden flight in 1986 was unplanned; during a high-speed
taxi test, the airplane became airborne and ran out of runway, with the crew being forced to continue the takeoff. The subsequent flight and landing went without further incident, but the
test crew were downgraded from their duties afterwards, despite having saved the aircraft.[6]
By 1990 two variants were planned, with a
search and rescue amphibian being designated the A-42, and a
military patrol version designated as the A-44.[6] The A-42 and A-44 versions were combined in 1993, but work on amphibians came to a halt in that year with an A-42 prototype 80% completed.[6][2]
In 2002, after renewed
Russian Navy interest, the A-40 prototype was restored to
airworthiness, and in 2006 the A-42 prototype was completed.[6] The Defense Ministry signed an
R&D agreement for $242 million rubles but pulled the plug in 2011.[6]
On 3 September 2019, the Russian Navy announced an order for three A-42 aircraft, with an expectation that the aircraft would use two
Progress D-27propfans, manufactured by
Motor Sich in Ukraine, as the powerplant. This variant would have an increased range of 9300 km.[2][7] This version would be upgraded to expand its combat capabilities, including a new radar comprising a viewing sight, heat seekers, piloting and navigational complex to measure sea waves, and new communications equipment.[2] An estimated service entry date was not provided.[2] Regardless, the Motor Sich engine manufacturing plant in Zaporozhie was destroyed by Russian forces in late May 2022 following the
2022 Russian invasion of Ukraine.[8]
Operational history
Between 1989 and 1998, the Beriev A-40 set 140 world records.[9]
Variants
A-40
Initial
ASW amphibian. 1 prototype built (second is 70% completed).
A-40M
Projected upgrade to the initial version, utilising a new search and targeting system.[10]
A-40P
Initially a projected
aerial firefighting version, able to scoop 25 tonnes (28 tons) of water and transport a team of firefighters.[11] Later the same designation was used for a projected
maritime patrol aircraft in direct competition with the
Tupolev Tu-204P.[12]
A-40PM/Be-40P
A projected civil version developed in 1994. Intended to
carry 105 passengers, an export version with
CFM engines was also offered. These studies led to the development of the
Beriev Be-200.[13]
Be-40PT
A projected cargo/passenger version designed to carry 70 passengers, 10 tonnes (11 tons) of cargo or 37 passengers and up to 6.5 tonnes of cargo.[13]
