BATH — Maine’s Bath Iron Works is gearing up for the christening of its next Aegis destroyer, the Spruance.

The warship is named for Raymond Ames Spruance, who commanded U.S. forces that sank four Japanese aircraft carriers at the Battle of Midway, hailed as the turning point in World War II in the Pacific.

On Saturday, his granddaughter will do the honor of christening the ship with a bottle of champagne.

This is the second destroyer to bear Spruance’s name. The first one was the lead class of the Spruance-class of destroyers that went into service in the 1970s.
