| has gloss | eng: Dissimilar air combat training (DACT) was introduced as a formal part of US air combat training after disappointing aerial combat exchange rates in the Vietnam War. Traditionally, pilots would train against similar aircraft for training, so, for example, pilots of F-8s would seldom train against F-4 Phantom IIs, and almost never against A-4 Skyhawks and never as part of a formal syllabus. From 1965 to 1968, US pilots found themselves over the skies of North Vietnam pitted against smaller, more nimble subsonic Soviet MiG-17 and the supersonic MiG-21. US pilots in USAF F-105 Thunderchiefs were barely able to exceed parity, and pilots in Phantoms and Crusaders were not able to achieve the hugely lopsided win/loss ratio achieved over Korea and in World War II. In fact, Air Combat Maneuvering (ACM) was not practiced by all fighter squadrons for a variety of reasons. |
