A helicopter profile at the patch’s center symbolizes advanced rotary training, and is orange to reflect the traditional color of orange on all Navy training aircraft. There are three versions of the tail rotor on the right side of the helicopter profile. The original version is a simple cross to indicate the blades of a tail rotor. Common lore is that a squadron commanding officer changed the tail rotor design during the Vietnam War to a peace sign, as a silent protest to the war. Then in the 1990s, another commanding officer devised yet a third design, a script-like 'S', this time reflecting the Sikorsky aircraft "S," probably reflecting his preference for Sikorsky aircraft - despite the fact that the squadron had by then transitioned to the TH-57 Sea Ranger, a Bell company product. All three versions of the patch are worn by squadron pilots to this day.
