' dream ' or ' inspiration ' , NATO reporting name : `` Cossack '' ) is a strategic airlift cargo aircraft that was designed by the Antonov Design Bureau in the Ukrainian SSR within the Soviet Union during the 1980s . It is powered by six turbofan engines and is the heaviest aircraft ever built , with a maximum takeoff weight of 640 tonnes ( 710 short tons ; 630 long tons ) . It also has the largest wingspan of any aircraft in operational service . The single example built has the Ukrainian civil registration UR - 82060 . A second airframe with a slightly different configuration was partially built . Its construction was halted in 1994 because of lack of funding and interest , but revived briefly in 2009 , bringing it to 60 -- 70 % completion . On 30 August 2016 , Antonov agreed to complete the second airframe for Aerospace Industry Corporation of China ( not to be confused with the Aviation Industry Corporation of China ) as a prelude to AICC commencing series production . </P>
