History Made: The Untold Story of the First Jet-On-Jet Shootdown by a U.S. Navy F9F Panther
After the combat, Russians believed they have downed at least five or six American aircraft, but because of the disorganized flying of the 139th GvIAP, none of the US aircraft was lost during the action.
The Korean war, that raged for three years from Jun. 25, 1950 to Jul. 27, 1953, saw the first widespread use of jet engine-powered fighter aircraft for both sides of a conflict.
These machines brought the air combat to a new, more faster and more lethal level. In fact the jet engines offered a significant increase in performance over the last piston engines, such as higher top speed, twice the cruise speed, greater ceiling and sustained climb rate. During the Korean War the fighter jets were deployed not only by the U.S. and their allies, but also by the North Korea and China and eventually some of these jets were flown by Russian pilots.
