Dark blue and gold are the colors traditionally associated with the Navy and reflect excellence and the sea. The symmetrical pattern of light blue and white on the field of the shield denotes the sea. The naval sword entwined with a serpent is inspired by the ship's name and refers to the minesweeper's ability to detect and neutralize a persistent mine warfare threat.
The crossed tridents and Greek warrior's helmet imply seagoing military preparedness and a strong defense while alluding to the name of MCM 10. The helmet and tridents are of the Greek era. They indicate the common goals and ideas of warriors throughout the ages. The oak branches suggest the ship's strong wooden construction.
The lightning bolts refer to the electronic search and detection capabilities of the variable depth sonar.
