Maybe it’s also a local public works job program :-)
Or maybe total crew needed for 3 8hr shift/day with fire control AND engineering requirements. Per Wikipedia, each of the main turrets on an Iowa-class required 85-100 crew in total.
I've
run the Guardian through a new spreadsheet based "A MegaTraveller Starship Design Example" and discovered that a 100 ton bay requires a crew of 50 versus the CT requirement of 2 per bay.
