The Navy has ordered an operational stand-down for all submarines following two recent accidents, charging commanders to “focus energy and intellect back onto the basics of submarine operations,” according to the Submarine Force’s leader. Vice Adm. Chuck Munns, U.S. Submarine Force commander, lamented that the two incidents — one which resulted in the death of two sailors — happened under standard operations. Normal operations will continue while commanders review recently completed operations and future planned evolutions, and evaluate areas of risk and risk mitigation, a statement said. They have a week to do it — reviews are due Jan. 19. The two incidents that sparked Thursday’s order involved four sailors swept from the top of the submarine USS Minneapolis-St.
