Russia has been showing off its first stealth fighter jet, the Sukhoi T-50, at an airshow near Moscow, watched by Prime Minister Vladimir Putin.
The plane, jointly developed with India, is expected to be marketed around the world as a cheaper alternative to America's F-22 Raptor.
Mr Putin said the aerospace industry was a vital part of Russia's efforts to diversify away from its reliance on oil and gas exports.
