More details of the Sukhoi T-50 stealth fighter emerged at the MAKS air show at Zhukovsky, outside Moscow, last week. It was confirmed that the T-50 is being designed to carry heavy, long-range missiles internally, its engines incorporate built-in features to reduce radar cross-section and infrared signature and a new engine for the aircraft, offering improved supercruise performance, is under development.

The initial service-entry engine for the T-50 is the United Engine Co. 117. It was not shown at MAKS but a UEC engineer confirmed it is very similar to the 117S engine for the Sukhoi Su-35S, that was. Both engines are derived from the AL-31F series used on the Su-27 and other members of the Sukhoi family. In particular, the stealth technology applied to the 117S will be carried over and improved for the 117.
