NORFOLK, Va. (WVEC) - The first of the U.S. Navy's new class of aircraft carriers has returned following a week of sea trials.

Last Saturday the future USS Gerald R. Ford (CVN 78) embarked from Huntington Ingalls Industries-Newport News Shipbuilding to conduct "builder's trials" to test various state-of-the-art systems.

The Navy says primary risk reduction objectives were successfully met, and the Navy and shipbuilder learned a great deal about the ship's performance during the extensive testing.

While undergoing trials, the Ford came to the aid of a sailor in distress on board another ship.

The Ford reportedly remains on track to conduct "acceptance trials" which are conducted by Navy inspectors and delivery to the Navy is expected this spring.

Construction on the Ford started in 2009. It was supposed to finish by September 2015, with costs at $10.5 billion. But there were issues with the carrier's advanced systems and technology, including aircraft landing equipment and power generation, leading to delays and cost overruns that increased the price tag to $12.9 billion.
