The wavy white chief denotes excellence at sea. The two turquoise wavy bars symbolize towing and salvage. The horned toad is the Navajo symbol of protection.

The compass rose and its quartered colors of black, white, turquoise and gold signifies the four sacred mountains of the Navajo Nation.
Crest
The torse adopts the first named metal and color from the shield and blazon. The rainbow annulet is derived from the Seal of the Navajo Nation, designed by John Claw, Jr. and adopted in 1952.

The demi-trident signifies mastery at sea and Navy expertise in accomplishing mission requirements. The crest is similar to the crest found on the USNS NAVAJO (T-ATF 169) seal, the difference being instead of silver, the trident is colored gold for continuity.
