This postcard is from my collection showing the United States Navy aircraft carrier USS John F Kennedy postmarked on the day it was decommissioned. My brother-in-law sent me this card, as he was assigned to this carrier as an instructor for new recruits. I gave him the postage stamps to put on it. This was an end of an era in the US Navy, as this was the last conventional powered aircraft carrier in service. All modern aircraft carriers are powered by nuclear reactors.
