Marine Corps · SSN history

547 Pilot, L-Boat

Appendix B lists the earlier SSN 547 title, Pilot, L-Boat, as “None,” excluding that specialty from Marine Corps use without naming a successor. The June 1945 title for 547 is Photo-Turret-Gunner, Aviation, but the shared number does not establish a conversion to that specialty.
