Yes, some of our aircraft are getting old, and our ships are even older, but consider South Africa. It’s Air Force does their Maritime surveillance. Defense  Web reports they use C-47/DC-3 airframes, updated to the extent of having their reciprocating engines replaced by turbines.  That makes the aircraft close to 70 years old. I have to think, this is what happens when you put the Air Force in charge of your maritime recon. It takes last place.
