SHIELD
The colors of the shield--red, white and blue--are both the Nations colors and signify sacrifice, prestige and dignity. Red further refers to the Marine Corps, while blue alludes to the Navy. Gold is shared by both sea services and is emblematic of excellence. Silver emphasizes precision and fortitude. The division of the shield is adapted from the City of Yumas seal, featured prominently on City Hall. It portrays the confluence of the Colorado and Gila Rivers and how they partition the land between Arizona and California, as well as form a boundary for the City. The winged shield and anchor pay tribute to Marine Corps Air Station Yuma. The cog wheel characterizes the heavy military equipment and vehicles the ship is designed to carry and also refers to the Armys Yuma Proving Ground. The trident is indicative of the Navy and maritime authority. The lightning bolt suggests speed, power and agility--characteristics associated with Spearhead-class ships.
CREST
The blazing sun, in all its glory, is a symbol of the State of Arizona. The saguaro cactus is a recognizable plant of the Southwest. The sheaf of wheat represents Yuma as a national center of agriculture. Together, they embody life and how it can flourish amidst a hostile environment.
MOTTO
NO CHALLENGE TOO DIFFICULT personifies the spirit and dedication of the crew and officers. The four silver compass roses on the scroll signify and honor the four Naval vessels named YUMA.
SUPPORTERS
The Marine Corps Mameluke and Army Officer swords depict teamwork and cooperation, as well as convey the ships capability to transport both Marine Corps and Army personnel and their military vehicles and equipment.
