SHIELD
Dark blue and gold are the colors traditionally used by the United States Navy. Sea waves are symbolized by the white wavy bar. A trident is the symbol of sea power; it is charged with a lightning flash to highlight MCM 6's modern electronic warfare capabilities. The pile, or "V" shape, pointing down toward the mine, emphasizes the ship's minesweeping mission: to search, detect and detonate mines. The pile also simulates a ship's bow cutting through the sea to clear critical sea lanes of enemy mines. The stylized detonated mine highlights the previous ship's service during the dangerous preinvasion minesweeps of Japanese and Korean waters.
CREST
The name of the ship is characterized by the dragon, symbolizing invincibility and power. The dragon breathing fire also dramatizes the action to remove the enemy threat. The cutlass together with the sabre reflects the team spirit of the enlisted and officers. The five stars on his collar honor and commemorate the previous USS Devastator's three battle stars for World War II service and two for Korean War service.
