Three sisters of an Irish-born recipient of the Navy Cross have christened a U.S. Navy warship bearing his name — and have secured a promise that the ship will visit Ireland. The future USS Patrick Gallagher is a guided missile destroyer that is under construction at Maine's Bath Iron Works that bears the name of the late Irish citizen and U.S. Marine. Lance Cpl. Patrick Gallagher survived falling on a grenade to save comrades, an act of heroism that was recognized with the Navy Cross. But he died later in Vietnam. The event was held Saturday at the shipyard in Maine.
