Ford is credited with leading fire-fighting parties that saved the light carrier USS Monterrey. He served honorably, even heroically, and was thence served as president.
I see no reason to complain about naming a carrier after him.
Since Reagan was not a veteran, I don't think that is the criterion. Other than serving a couple of replacement years as a lame-duck unelected president, there is little to distinguish Ford from hundreds to thousands of other sailors. Admittedly, he was a very nice man. Name a hospital ship after him.
