Texas submarine returns from sea trials

The first submarine to get its final assembly at Northrop Grumman’s Newport News shipyard in 10 years returned Wednesday from successful initial sea trials to test its performance. In two days of trials, the Texas submarine was brought up to speeds of faster than 25 knots, dove deeper than 800 feet twice, turned sharply and stopped quickly, officials said. “We made sure than everything worked as advertised, and she responded,” Navy Capt. John Litherland, the Texas’ commanding officer, said after the sub returned to the Newport News yard.
