In early 2010, full afterburning thrust was reached in testing of the first production standard engine.

Consequently, the low afterburning thrust implies a high afterburning SFC.

But Mar- aklov's last commands were executed, and DreamStAr's turbofan engine was at full afterburning thrust and the brakes were off.

A more powerful Lyulka AL-7 turbojet was installed, providing 9.8 kN (2,210 lbf) more afterburning thrust for improved climb rate and high-altitude performance (and to compensate for increased weight).

Although externally similar to the Crusader and sharing with it such design elements as the variable incidence wing, the new fighter was larger and was powered by the Pratt & Whitney J75-P-5A engine generating 29,500 lbf (131 kN) of afterburning thrust.
