A fine photo of Plunger cruising close off the coast of Hawaii, probably Oahu or possibly Lahaina, Maui approximately 1940. By the date of this photo, the Submarine Force had shifted away from the "P" class identifiers on the superstructure and fairwater and had changed to displaying hull numbers. This is a practice that continues to the present day.
