These Two Engines Are The Backbone Of Russian Fighter Jets Worldwide

Only a handful of engines power most of the world’s fighter jets, and only two families of engines power most of the Russian fighters (as well as most Chinese fighters that haven’t been upgraded with recently produced Chinese engines). These two families of engines are the Klimov RD-33 turbofan and the Saturn AL-31 turbofan. These engines are found on a range of fighter jets (and even nonfighter jet platforms like advanced UAVs).
