I think only the C-130 has been the only other airplane in continuous production for 50+ years. It was a great run by the Mig-21/J-7/F-7/F-13 design, producing almost 11,500 airplanes. The Mig-21 was also a great adversary, and produced about 20 Aces, most from the NVAF.

Quite impressive. I guess we will see the aircraft for many decades to come.
On the other hand, I am impressed how long some out of production aircraft remain in service: F 4 Phantom gets retired in Germany this year and remains in service at other countries, and even more impressive is the service life of the B-52 and KC -135.
How much do a 1960s Mig-21 and a 2013 J-7 have in common, btw?
