A couple of submarine songs come to mind. Two are by Phil Ochs, "The Thresher", and "The Scorpion Departs But Never Returns". Interesting that Ochs, known for anti-war and anti-military songs, would write 2 about subs. The Kingston Trio also recorded a sub song on the album Sunny Side called "The Ballad of the Thresher". As for steel tubs, I'm not quite sure what ya mean. Is it a generic term for any steel ship, or a steel plated warship, or something more specific?
