FLYING COST!

What is the Per hour Flying cost of aircraft such as the f-15,f-16,f-18,su-27/30mki,mig-29,m2k,gripen etc etc And what are airframe lives etc etc..I remember reading somewhere that the M2k is cleared for 7200 hours and the f-15C’s with the USAF have just been cleared for 8000 hours..How do these figures for western fighters compare to those of the Soviet/russians ..I have on many occasions heard that the Western fighters are cheaper to maintain over the long run and that their combat availability is more..Can we shed some more light on this.
