Need help with this item.
Someone having served in the U.S. submarine force or familiar with same can clarify.
American military payment certificate [MPC] from that era of the Vietnam War, value of five cents.
That particular image as found on the MPC giving me trouble.
This is a Skipjack [?] class American submarine with some sort of bow mounted sonar?
Sonars on American subs of that period mounted internally and not externally. That bow mounted sonar array does resemble the type of array as might be found on a British diesel/electric boat of the Oberon class but not an American Skipjack.
Perhaps this is a composite image for artistic effect. I just cannot say.
Devoted readers to the blog know better?
