What is an f4 fighter jet?

The F4 (F=Fighter/P=Pursuit/B=Bomber/RF=Reconnaissance Fighter/A=Attack) Phantom II is a TWIN engine, TWIN seat (2 crewmen) jet FIGHTER/BOMBER. Originally designed to intercept and destroy enemy bombers to protect the warships of the USN. Like nearly all jets, it was forced into bombing missions in Vietnam, thus becoming, like most of the other jets, a FIGHTER BOMBER. However, not like the other jets, the Phantom was GOOD AT IT! The F4 could do both bombing and fighting...and do them well. The Phantom is America's last ACE's of the 20th century (5 aerial kills each in Vietnam for the USAF and USN...each flying the F4 Phantom II Fighter/Bomber). The Phantom was used in Vietnam by all fighting branches of the military; USAF, USMC, and USN. More Phantoms were produced than any other Vietnam era jet (and more Phantoms were lost than any other US jet during the Vietnam War...nearly 800 destroyed). You can't tell if the F4 has two engines until you look at either the air-intakes or the tail exhaust pipes, and see two at each end. Twin engine for the Phantom does not mean an engine on each wing like the B57 Canberra bomber, as an example.
