According to Pascagoula Mississippi Press, while the welders, fitters and engineers at Northrop Grumman work on the ships that will soon form the nucleus of the Navy's updated surface fleet, two companies are providing critical shipbuilding assistance. El Segundo, Calif.,-based Computer Science Corp.'s Advanced Marine Unit in Pascagoula and Gautier-based Omni Engineering are working under contracts with the Navy's Supervisor of Shipbuilding, Conversion and Repair, to provide support with evaluating and analyzing ship designs and engineering plans and monitoring various parts supply chains for the ships. In two cases, the companies are partnered under joint contracts on certain shipbuilding programs.
