"There Are No Atheists In Foxholes"

There's no new submarine news, and I've run out of unclassified sea stories, so here's a story about a Catholic priest celebrating Mass underway on USS Missouri (SSN 780).
Services on board submarines are regularly provided by lay leaders. Hoar added that lay leaders play a pivotal religious role to submariners.
"As members of the military we do our jobs daily, but on Sundays we have the opportunity to gather and pray together," said Roa. "It meant a lot to me to have a Catholic priest on board."
How did you take care of your religious needs when underway?
