In the past two decades, the U.S. Navy has undertaken significant projects in the computer aided design, manufacturing, and service life support areas. A few of the those most related to the shipbuilding programs are listed in Table 1 along with the phase in the ships life cycle they were primarily supporting. CASDAC Computer Aided Ship Design and Construction was the grandaddy of them all, dating back to the late 60s when the Navy was designing and building its own ships. The projects goal was to develop software for doing early stage design, through contract design, and detail design at the naval shipyards. They labored under the dual burdens of expensive hardware and relatively unfriendly software development environment, with clumsy operating systems, occasional need for assembly language programming, and early compiler limitations ions. Nevertheless, many programs that are still with us today began during that era, including SHCP Ship Hull Characteristic Program SSDP Ship Structural Design Program HULDEF Hull form Definition and SDWE Ship Design Weight Estimating. The state of CASDACVs progress by the early and mid 7Os is well described in references 1 and 2. The monument al CASDOS Computer Aided Structural Detailing of Ships was developed under CASDACs sponsorship and actually used to build 6 LCUs for the Army and for Saudi Arabia. Over half of CASDACs efforts were oriented toward shipyard product ion software, including electrical wiring and fluid piping systems programs. In 193l, long after the end of new ship construction at the Navy yards, CASDAC was subdivided into two distinct programs, the CSD Computer Supported Design programs, carrying on the ship design software development, and portions of the MANTECH manufacturing and technology program for advancing industrys efforts to improve shipbuilding productivitiy through automation and technology.
