Russia shows off Sukhoi T-50 stealth fighter
India is expected to buy up to 200 of the T-50 craft
Russia has demonstrated its first stealth fighter, designed as a cheaper alternative to the US F-22 Raptor.
The Sukhoi T-50, jointly developed with India, flew publicly for the first time at the MAKS 2011 air show near Moscow.
The supersonic T-50 aims to match the latest US design, handling manoeuvres that are impossible to older aircraft.
Russia plans to make up to 1,000 of the jets over coming decades, with India expected to buy up to 200. However, full production is not due before 2015.
Mikhail Pogosyan, president of the Russian state-run United Aircraft Corporation which is developing the craft, said: "The T-50 jet will provide the backbone not only of the Russian air force but also that of India."
The Russian Air Force was expected to buy up to 200 of the craft, which is intended to replace the SU-27 fighter, he said.
India, Russia's biggest arms client, agreed to develop the project in tandem with Moscow during a December 2010 visit to New Delhi by President Dmitry Medvedev.
