The Fast Attack Wing plaque on the Daedalus.

The Fast Attack Wing is a branch of the United States Air Force for deep space defense. The 304 Daedalus is known to be a member of this branch. It is identified to the inhabitants of the universe as an Tau'ri ship by the symbols on the side of the ship representing Earth on the Stargate. Whether any other vessels are included in this wing is unclear. (SGA: "The Daedalus Variations")
