Heraldry
The Roan's Two Crests
Information provided by Captain Jack Nuttall, USN (Ret.)
First Crest
The Angry Octopus
The first crest was round and consisted of an angry red-eyed octopus with a submarine in its grasp, and a bolt of lightning flying out.
On July 1, 1957 the Commander Destroyers Atlantic Fleet (COMDESLANT) ordered that all such symbols be removed and appropriate new ones be devised and adopted.
Second Crest · Adopted January 1958
The Golden Trident

The new crest is in the form of a shield, with the ship's hull number on top and the ship's name across the bottom. The body of the shield represents the Royal Blue Sea separated from the Light Blue Air by a simple wavy line, and incorporates three symbols:
- The Golden Crown of Success. "SUCCESS" was our radio call in 1957-58. The Roan achieves success in all its endeavors in the air and sea.
- Golden Trident. King Neptune's weapon — to be used offensively.
- Golden Lightning Bolt. Placed from upper left to lower right (when worn) — different from normal usage and placement. The Roan and her crew were different.
