Procurement efforts are expected to be complete by December 2012.
"This award is the first step leading to continued construction of Aegis destroyers at BIW for many years to come," Bath Iron Works president, Jeff Geiger, said.
"As the lead shipbuilder of the class, we have a track record of excellent performance in both procurement and construction activities across the 31 ships of this class we've built in the last two and a half decades.
"We're excited about the opportunity to continue that performance."
