In aerobatics, the cobra maneuver (or just the cobra), also called dynamic deceleration, [1] among other names (see § Etymology), is a dramatic and demanding maneuver in which an airplane flying at a moderate speed abruptly raises its nose momentarily to a vertical and slightly past vertical attitude, causing an extremely high angle of attack and making the plane into a full-body air brake ...
Pugachev's Cobra; the nose of the aircraft is pulled up suddenly. The aircraft pitches up to 90–120° angle of attack. The nose then falls back to the horizontal, and the aircraft accelerates away in the original direction ; Kulbit; post-stall maneuver similar to Pugachev's Cobra, but going to 360° pitch angle, flying a "loop"
The design also allowed the plane to enter a "super stall"; which can be described as an uncontrollable stall affecting aircraft with specific wing configurations when experiencing high alpha numbers. [29] Due to this, J 35 pilots were trained to prevent super stalls, and this training led to the development of the cobra maneuver.
The Cobra, as performed by non-thrust vectoring aircraft, still depends on the aircraft moving through air; however, it does not involve the aircraft's aerodynamic surfaces and normal laminar airflow, but rather the whole airframe as a solid shape traveling through air, and its center of gravity in relation to the thrust vector.
The aircraft's main design elements date to early 1965, from the internal Northrop project N-300. The N-300 was derived from the F-5E, and features a longer fuselage, small leading-edge root extensions (LERX), and more powerful GE15-J1A1 turbojets, rated at 9,000 lbf (40 kN).

The alternate name, "Frolov's Chakra", refers to Russian test pilot Yevgeni Frolov, the pilot who first carried out the maneuver, while "chakra" is a yogic term, meaning "vortex" or "whirlpool". The Kulbit drastically decreases the aircraft's speed and could theoretically be used to cause a pursuing aircraft to overshoot its target.
