The last F-15C was built in 1985, and the type is still the backbone air-superiority fighter for the USAF, since there aren't enough F-22 Raptors to replace them. The B-52 is still one of the US's primary long-range strategic bombers, and the last one rolled off the assembly line in 1962, with the type anticipated to still be in service into the 2060s!
Depends which period of aviation history you compare to, you wouldn't want to be rocking in a Fokker Dr.I in 1940 or Bf-109 in 1960.
Clone Wars saw three generations of fighters (V-19 -> Z-95 -> V-wing) in just three years.
