The flag follows the design of the Great Seal of Guam: a almond-shaped emblem (Chamorro slingstone) bordered in red, depicting a proa sailing in Agana Bay near Hagåtña cliff, with 'GUAM' inscribed in red. The blue field represents the surrounding Pacific Ocean and loyalty to the United States.
History

Construction
A 22:41 ratio dark blue field with the circular Guam coat of arms centered, bearing a proa, cliff, and the word GUAM.
