"Russia on Tuesday unveiled its new Sukhoi stealth fighter jet designed to compete with the US F-35 and capable of striking six targets simultaneously. Dubbed 'The Checkmate,' the plane was first shown to a reportedly 'pleased' President Vladimir Putin before the launch at a biennial airshow outside Moscow. Reports first surfaced that the jet was being manufactured in May last year. According to the launch video it was developed 'in record time'."
