The three days of at-sea demonstrations and testing of the San Antonio-class Somerset was observed by the U.S. Navy's Board of Inspection and Survey and included all ship systems.
"We have now completed successful sea trials on nine LPDs, and each ship continues to get better than the previous one," said Mike Duthu, Ingalls' director of the LPD program. "Somerset proved herself ready as we demonstrated major systems onboard the ship.
We have a very active production line associated with the LPD program, and through our new build strategies, more outfitting is taking place earlier in the process, which improves our efficiency."
The Somerset is 684-feet. Its primary mission will be to transport as many as 800 Marines, their fighting vehicles and aircraft.
HII said two other LPDs are under construction, one scheduled for completion is 2016 and the other scheduled for completion the following year.
