Beriev A-40 / Be-40 Albatross
The A-40/Be-40 Albatross Mermaid turbofan-powered intermediate-range antisubmarine, search-and-rescue and patrol amphibian, first flown December 1986 and ordered for the Russian Navy in 1992 but not funded.
The A-40 amphibian aircraft is intended for antisubmarine warfare in the near coastal zone at any time of the day and year, in VFR and IFR weather conditions.
The aircraft is provided with an inflight refueling system.
Its onboard equipment provides for automatic solution of flight/navigation problems, search, detection, tracking and destruction of hostile submarines both in surface and submerged positions and on the sea bottom.
The equipment comprises a search/sighting system, a flight control and navigation complex, communications facilities, and other equipment. The search/sighting system consists of radar, sonar and magnetometric subsystems.
The engines are started by an auxiliary power unit and the cruise turbofans are equipped with a thrust reverser, thereby reducing the landing roll and the abortive takeoff distance.
The type first showed up in US re-connaissance photographs during 1988 satellite passes over Taganrog but the first "closeups" came with the amphibian's surprise debut at an air show in August 1989. NATO dubbed the aircraft, christened Alba-tross by the G M Beriev Taganrog Avia-tion Scientific-Engineering Complex, "Mermaid".
A requirement for the two large 26,455 lb static thrust PERM Soloviev D-30KPV engines to be placed away from ingesting water saw an over wing configuration incorporated in the design. The rear part of the pylon ac-commodates RD-60 booster engines providing an increase in thrust by 6065 lbs st apiece. In the SAR role the A-40 can cover 1240 nm (2000km) from its base and take on board up to 54 survivors. The crew usually totals five plus a rescue team of around four to six.
An improved search-and-rescue variant became the Be-42 (sometimes referred to in the West as A-45).
