US air force questions

What is the composition of the US Air Force ?
How many planes of every type the US has got actually in service ?
For example:How many F-15s in service?How many F-16s,18s…
How many tankers AWACSes,tankers,E-Warfare planes,bombers…
I read somewhere that the US had 6476 aircrafts in service in the Air force.
Is it right?And what is the distribution by type?

Thank you.
