Kathleen O’Brien / The Times Record BATH — The future USS Daniel Inouye, a Bath-built Arleigh Burke-class destroyer, returned from successful at-sea acceptance trials Friday, according to a military public relations firm. Meanwhile, the shipyard on its website has noted a dip in its production rate. Acceptance trials serve as the Navy’s opportunity to test the ship’s mechanical and electrical technologies that control navigation, communication and propulsion to ensure they meet the Navy’s standards. The ship’s smooth sea trails is a good confidence boost for the shipyard after a rocky stretch of mounting delays, said Craig Hooper, CEO of Themistocles Advisory Group, a Maryland-based national security advisory firm.
