The patch consists of a red "39" within the nucleus of a yellow atom. The atom is set on a dark blue circle, ringed by a silver border. At the bottom is the squadron motto, "Potentia Vincere", which is Latin for "The power to conquer". The atom represents the unlimited abilities in each squadron member, and the unity of the squadron as a whole. The colors represent the four classes, and the unified design represents the cooperation necessary among the classes to insure an effective squadron. This was the squadron's original patch, which was discontinued in 1980, but revived in 1991.
