Defense contractor Raytheon Co. said Monday it has received a $241.3 million U.S. Navy contract to deliver additional software for the Zumwalt-class destroyer.

Software development will help integrate interaction with computer components for the ship's engineering machinery controls and damage control systems, particularly to control ship propulsion, integrated power and other systems.

Work will be done at Raytheon in Tewksbury, Mass., and the Seapower Capability Center in Portsmouth, R.I.
