2D向量推力系統亦都係首次喺Su-35上面測試，呢個系統係基於Su-37專案嘅研發成果。新嘅2D向量推力引擎稱為117S，佢係為咗代替而家嘅AL-35同埋AL31-F引擎而研發。
The 2D vector thrust system was also tested for the first time on the Su-35, which was based on the results of the Su-37 project. The new 2D vector thrust engine, called the 117S, was developed to replace the current AL-35 and AL31-F engines.
