Su-57 vs F-22

The Su-57 vs F-22 comparison leads us to conclude that the multirole fighter manufactured by Sukhoi has five clear advantages over the combat aircraft produced by Lockheed Martin. These five technical and combat characteristics, which give the Su-57 the upper hand over the American fighter, have to do with the power plant and, perhaps, with its layout and shape.

Although the Pratt & Whitney F119-PW-100 turbofan engines that propel the F-22 Raptor are slightly more powerful than the Su-57's in terms of lbf dry thrust, the Russian aircraft power plant is more efficient, especially at reaching higher speed and maintaining it for longer distances. This means that the Sukhoi aircraft's Saturn AL-41F1 turbofan engines are more efficient in fuel consumption, for it has a longer ferry range than the American warplane. Thus, having more advanced jet engines render the Su-57 capable of carrying a heavier bomb-load than the Raptor.

However, the Lockheed Martin F-22A apparently has better stealth design and material than the Russian aircraft. The Sukhoi Su-57 has a layout and design (shape) better for higher speed, resigning somewhat to a fully stealth mode. In the chart/diagram below, you will see that the Russian plane can comfortably fly at the supercruiser speed of 2,100 km an hour (Mach 2), whereas the American aircraft's supercruiser speed is 1,963 km per hour (Mach 1.82) at high altitude.

The Su-57 armament payload amount to 9,000 kg, with an internal bay for smart bombs or air-to-surface missiles, plus six external hardpoints. Thus, it is able to carry the Kh-22 anti-ship missile, plus bombs. The F-22, on the other hand, has a bombload of 4,500 kg.
