was noticed and pilots started to purposely use it to drop speed. The Swedish test pilots who discovered the cobra were and , who developed the technique around 1961–1963. The Swedes named the maneuver "kort parad" after a fencing maneuver of the same name, known as "beat parry" in English. The Swedish pilots soon considered how to use this move in combat to get a pursuing aircraft to overshoot, putting it in a perfect position for a riposte, and it was not long until it was proven viable during mock dogfights. In real combat, depending on the situation and the execution of the maneuver, it could be used to confuse the enemy by making it lose the target or to overshoot, which would allow the pursued pilot the opportunity to either flee from combat or re-engage. However, the maneuver was very difficult and dangerous to use as anything more than a last-ditch effort, as without precise execution the aircraft's slow speed after the maneuver would make it an easy target. The maneuver originated with the Bråvalla Wing, the first one to receive the Saab 35 fighter plane. As the fighter was adopted by other wings over time, so was the maneuver. The Scania Wing apparently called the maneuver "Wacka", which has no real meaning in Swedish. Sweden effectively shared borders with the Soviet Union over the Baltic Sea, so both sides regularly flew into the international space between the two. In the event, the Saab 35s regularly intercepted and escorted Soviet planes away from Swedish airspace. Sometimes these encounters would result in non-combat dogfights, which were either playful or threatening in nature. Apparently, the cobra maneuver was used during some of these engagements, surprising the Soviets. Late in the Saab 35's service life, the maneuver was used as a 'secret weapon' by Saab-35 pilots in mock dogfights facing the more advanced Saab 37 fighter. The Saab 37 was unable to safely enter super stalls, and therefore its pilots did not receive any major training against its use. The cobra maneuver was therefore unknown to many Saab 37 pilots prior to facing it in competition. Due to the appeal of the tactic, some Saab 37 pilots attempted it, but to their dismay were unable to effectively perform it above speeds of as the Saab 37 couldn't safely handle the necessary gs, rendering it effectively useless in combat.
