The U.S. Navy on Wednesday awarded Bath Iron Works a $11 million contract modification to provide lead yard services for Arleigh Burke-class destroyers.

Work will include engineering and technical assistance for new Arleigh Burkes, also known as DDG 51s. Lead yard services include serving as liaison for ship construction, general class services, class design contractor services, class change design services for follow ships, and ship trials and post-shakedown availability support.

In June 2018, Bath Iron Works was awarded the lead yard contract for Arleigh Burkes potentially worth $305 million.

The shipyard currently has four Arleigh Burkes under construction, as well as the third Zumwalt-class destroyer, the DDG 1002. Construction of the DDG 127 (the future USS Patrick Gallagher) has not yet begun.

In September 2018, BIW was awarded $3.9 billion in contracts to build four more Arleigh Burke destroyers to be procured in the next five years. The contract includes options for five additional ships.
