Blair spent over 34 years in the United States Navy. He served on guided missile destroyers in both the Atlantic and Pacific fleets and commanded the Kitty Hawk Battle Group between 1994 and 1995. Blair commanded the USS "Cochrane" from 1984 to 1986 and the Pearl Harbor Naval Station from 1988 to 1989. Blair was known as a thoughtful commander, but is also remembered for moments of levity during his leadership. He is believed to be the first naval officer to ever attempt water-skiing behind his modern destroyer as skipper.
