Another Grayback
The demise of the Grayback, on the other hand, did not signal the end of the Grayback’s legacy. Due to the fact that a second Grayback submarine, classified by the Navy as SSG-574, entered service in July 1957, 14 years after the first vessel went down in the Pacific, this is the case. She was also launched in a fitting memorial to her late husband by Mrs. Virginia S. Moore, the widow of the original Grayback’s final captain, Commander John A. Moore, who was the ship’s final skipper.
