Russia is capable of exporting over 600 units of the fifth generation fighter Sukhoi. According to experts of the Center for Analysis of the Global Arms Trade, it is planned to build at least a thousand of these aircraft. The expected order of the Russian Air Force during the years of 2020-2040 with a favorable economic scenario in the country may reach 400-450 units.
In general, the volume of potential export orders for the PAK FA, considering India, could reach 548-686 fighters. Currently, the only foreign member of the PAK FA program is India, which plans to have no less than 250 units of fifth-generation fighter in service of its air force. They will be built on the basis of the Russian PAK FA, but the level of licensing control of the Russian side for the future model of the fifth generation aircraft is unknown.
In July of 2010, General Director of Sukhoi Mikhail Pogosyan said that the contract with India may be signed before the end of this year. The details of future cooperation of Sukhoi and the leading Indian corporation Hindustan Aeronautics (HAL) participating in the development have not been reported.
