The first Bath-built Zumwalt stealth destroyer has been officially presented to the U.S. Navy.

The Times Record reports that the $4 billion ship was delivered to the Navy in May 2016, but the vessel still needed to be outfitted with its defense software and weapons. Those were installed by Raytheon Integrated Defense Systems.

The vessel, which was presented to the Navy last week at its homeport in San Diego, will now move onto at-sea testing, according to the newspaper.

The ship is named after Adm. Elmo Zumwalt, who served as chief of naval operations from 1970 to 1974 and fought in World War II, Korea and Vietnam, The Times Record reports.

It is one of three Zumwalt stealth destroyers the Navy ordered from Bath Iron Works, down from the 32 originally envisioned in the early 2000s.
