According to Bill Sweetman, the Su-57's high operational speed and altitude combined with its standoff weaponry could be hinting at its role as a "sort of airborne sniper", designed to fly fast and high to engage enemy support aircraft. This claim is supported by Russia's intentions to adapt the new R-37M (Izdeliye 810) air-to-air missile with range of more than 300 km to the Su-57's armament, giving it a role similar to the MiG-31BM interceptors. Newly designed anti-ship and hypersonic weapons like Kh-47M2 Kinzhal could also enable the Su-57 to perform as a maritime strike aircraft.
