"Spruance", being the first gas-turbine powered ship in the U.S. fleet, had an underway replenishment breakaway flag (flown while pulling away from receiving supplies and fuel from a logistics ship at sea) that was a replication of the large yellow warning seen on the side of aircraft carriers, with red block letters saying "BEWARE JET BLAST" on a large yellow background. Upon "breaking" (unfurling) the flag on the halyards, they would play the theme song from the 1976 film "Rocky" as they increased speed and sailed ahead of the logistics vessel.
