A second class of Aegis ship began with concept studies in 1978. The class was to replace the aging DDG-2 and DDG-37 class destroyers and handle the same air threats as the CG-47 class. The project responsibility originally lay outside of PMS 400, in another functional code in the Naval Sea Systems Command (NAVSEA 93). However, by May 1982, the project was put under Meyer's control in PMS 400, with a lead ship awarded 1985 to Bath Iron Works, Bath, Maine. Like the "Ticonderoga", the ship was designed with an Aegis Combat System, modified for installation in the destroyer and less heavily armed. The ship was commissioned as on July 4, 1991.
