The Su-57 fifth-generation fighter has been equipped with hypersonic weapons, according to the Chief of the Main Staff and First Deputy Commander in Chief of the Russian Aerospace Forces Lieutenant General Alexander Maksimtsev.

"In accordance with the state defense order, the Aerospace Forces annually receive advanced and modernized weapon systems. The pace of deliveries of fifth generation Su-57 aircraft is increasing, along with modern aviation strike systems and hypersonic weapons," the commander reported in an interview.

The Military Watch Magazine said the class of hypersonic missile in question remains highly uncertain, although it has been confirmed that an air-launched derivative of the Zircon hypersonic cruise missile currently deployed from Russian Navy surface ships and submarines was under development.

Integrating the Zircon onto the Su-57, which combines a very long range with advanced stealth capabilities, could significantly increase the threat to hostile shipping, particularly as the Su-57 fleet is projected to grow to several hundred fighters by the late 2030s. A number of advanced new missile classes have been developed for the Su-57, with state media reporting in October 2023 that a new class of very long ranged cruise missile based on the Kh-101/102 that equips strategic bombers had been integrated onto the fighter. The missile was smaller than the original Kh-101/102, but retained the same range, which is estimated at approximately 3,500 kilometers. This would provide the Su-57 with by far the longest engagement range of any fighter class in the world, and was achieved by "a significant reduction in the size of the new ammunition thanks to the perfectly refined design of the folding wing and internal layout, as well as the use of a new small-sized bypass turbojet engine," the Military Watch Magazine said.
