The Su-57 features two tandem internal armament bays, each about 4.4 m (14.4 ft) long and 0.9 m (3.0 ft) wide, as well as two side weapon bays with triangular section fairings beneath the fuselage near the wing root. The aircraft can operate from air to air, air to ground, and marine base operations.
As a result, it is capable of carrying all types of missiles, including beyond visible-range (BVR) missiles as well as medium and short-range missiles. The principal medium-range missile is the active radar-homing R-77M (izdeliye 180), an updated R-77 derivative with an AESA seeker, dual-pulse motor, and conventional rear fins.
The Su-57 is vaporware. They aren’t actually that stealth and Russia can’t even make enough for a single squadron for themselves.
