So this blog will be about Vietnam era military planes. Some people might know the F 4 Phantom II, some might not. Others might know the F 14 Tomcat (made an appearance in Top Gun), which is the most likely the most common jet known. The F 4 Phantom II was produced by McDonnell Douglas in 1958. It made its first appearance to the Military in 1960 with a test flight. The F 4 is equipped with one 20 mm gun.
