History Sukhoi Design Bureau Sukhoi Su-47 Berkut
(Russian: Сухой Су-47 Беркут, lit. 'Golden Eagle')
NATO reporting name Firkin
The Sukhoi Su-47 Berkut (Russian: Сухой Су-47 Беркут, lit. 'Golden Eagle') (NATO reporting name Firkin), also designated S-32 and S-37 (not to be confused with the twin-engined delta canard design offered by Sukhoi in the early 1990s under the designation Su-37) during initial development, was a Russian experimental supersonic jet fighter developed by the JSC Sukhoi Company. A distinguishing feature of the aircraft was its forward-swept wing[3] which gave the aircraft excellent agility and maneuverability. While serial production of the type never materialized and the configuration was not further pursued, the sole aircraft produced served as a technology demonstrator prototype for a number of advanced technologies later used in fourth-generation fighter
Su-35 and fifth-generation fighter Su-57

Originally known as the S-37, Sukhoi redesignated its advanced test aircraft as the Su-47 in 2002. Officially nicknamed Berkut (Russian: Беркут) (the Russian word for the golden eagle), the Su-47 was originally built as Russia's principal testbed for composite materials and sophisticated fly-by-wire control systems, as well as new airframe technologies.
Design
The Su-47 is of similar dimensions to previous large Sukhoi fighters, such as the Su-35. To reduce development costs, the Su-47 borrowed the forward fuselage, vertical tails, and landing gear of the Su-27 family. Nonetheless, the aircraft includes an internal weapons bay, and space set aside for an advanced radar.

In February 2017, it was announced that Russia's United Aircraft Corporation had signed a contract with its subsidiary Ilyushin Aviation Complex for the development of a new version of Ilyushin Il-96-400 wide-body passenger airliner to compete with the Boeing 777-9 and Airbus A350-1000.

Projected double-deck version of Il-96 for 550-600 passengers and powered by Kuznetsov NK-93 propfan engines. Following flight tests in 2007 the engines were removed and the aircraft was not developed further.
