Naval tradition used to motivate sailors upon the conclusion of underway replenishment (UNREP), although using breakaway music is at the discretion of the captain, and not all commands use it.
[1] When the two ships involved in the UNREP conclude their transfer of fuels and stores and commence their breakaway, a song is played over the 1 Main Circuit.
Some commands will allow the crew to vote on a song from a list of popular choices, usually during morning quarters.
[2] Breakaway music may sometimes be related to the name of the ship, such as the "Theme from Star Trek" (USS Enterprise (CVN-65)) or "Kansas City, Here I Come" (USS Kansas City (AOR-3)).
The fast combat support ship, and oiler, USS Camden (AOE-2) played the "Baby Elephant Walk" (written in 1961 by composer Henry Mancini, for the 1962 release of the movie Hatari!)
