Jet planes had yet to be developed , so there were none at Pearl Harbor .
kinds of fighter planes
You mean were WWII fighters smaller than today's jets; because "modern fighter planes" are jets. Generally yes, today's JETS are much larger than WWII propeller driven airplanes. But there were exceptions, the US WWII P47 Thunderbolt would be much larger than a MiG 17 Vietnam era jet. The largest US single engine JET was the F105 Thunderchief; you could literally walk underneath an F105 jet, while it's parked on the ground.
The USAF has approx. 2132 fighter aircraft. The US Navy has probably several hundred if not over a thousand, putting the amount of fighter jets in the US up to about 3000.
The most expensive fighter jet is the F-22 Raptor. The most expensive Fighter used to be the F-15 eagle.
The Vietnam War escalated from a Viet Cong guerrilla war to a war involving regular Army units of the North Vietnamese Army; including jet aircraft combat between US Air Force/US Navy jet fighter planes against North Vietnamese Air Force fighter aircraft.
I would say at this time, the US has the most fighter planes.
The F-86 Sabre was arguable the most advanced US fighter jet in 1950. It remained so throughout the Korean War.
US fighter jet's designation start with F as it stands for Fighter, B for bomber and C for cargo etc...
The F-16
It takes about 6 hours.
The US name for fighter aircraft until 1946 was "Pursuit Aircraft" , hence the letter P in front of the model number.
