You know you are old when you can remember when ships were brand new and just fresh in commission, and then you read they have been decommed, sink-exed or sold.
Heck the Air Force is still flying planes built a minimum of 9 years before I was commissioned, most of them 10+ years earlier. Some of them are flown by the grandchildren of the first generation of pilots to fly them. Not just the same type of airplane, the same airplane by tail number.
B-52H. Last one rolled off the Boeing line in 1964.
