Shield
The shield is separated by a wavy part at the top, signifying the two fields (air and sea) in which the USCGC STONE performs its mission. The aircraft propeller at the top symbolizes the NC-4 piloted by Commander Elmer F. Stone during his historic trans-Atlantic flight. The ships propeller below refers to the USCGC STONE and its high endurance capabilities. The eight separations of the border suggest the building blocks or foundation that Commander Stone developed for the future of U.S. Coast Guard aviation. The border further alludes to fortitude and defense, while gold refers to Commander Stones service and achievements.
Crest
The tower and oak wreath are from the Order of the Tower and Sword, a Portuguese order of knighthood and the pinnacle of the Portuguese honors system, which was awarded to Commander Stone upon his completion of the first trans-Atlantic flight. The seven gold stars refer to the seven lives Commander Stone helped to save during a stormy rescue of shipwrecked seamen on the lumber laden schooner, C.C. WEHRUM off False Cape, Virginia.
Supporters
The seagull is known for its adaptability to water and land and is a symbol of search and rescue. They stand upon rocky terrain to support the shield, with wings raised to suggest readiness in flight. The water flowing between the mounts refers to the ocean between two continents, alluding to the first trans-Atlantic flight that was successfully completed by Commander Stone and his crew.
Seal

The chained border is a symbol of teamwork, unity, and strength of the crew, as well as representing cohesion between the surface and aviation communities of the United States Coast Guard.
