a difÞ cult system to use over long tests, requiring very experienced operators. You couldnÕt change angle of waves, so we would have to change the angle of the model. We couldnÕt create the steep- est waves. The new wavemaker will be much easier to use and allow for more complete testing.Ó Etxegoien said the navy knows a lot about the kinds of seas its ships may have to sail upon. ÒWe can create what we might expect to Þ nd because we have that data. We have 20 years of ex- perience of on increasing and improving the data of the conditions in those areas where we expect to operate.Ó There are other wavemaking facilities for performing hydrodynamic testing of ship modelsÑsuch as in the Nether- lands, Germany, China, Japan and Bra- zilÑbut Arcano said none can do what the Carderock team is able to accom-plish today. ÒThis is the most advanced of its class in the world.Ó As a major component and Þ eld activ- ity of the Naval Sea Systems Command, the Carderock Division is the NavyÕs center of excellence for ships and ship systems, providing cradle-to-grave tech- nical support for surface and undersea platforms. Carderock is the full-spec-trum research and development, test and evaluation, engineering, and Fleet sup- port organization for the NavyÕs ships, submarine, military watercraft, and un- manned vehicles. The Carderock Division consists of approximately 3,200 scientists, engi-neers and support personnel working in more than 40 disciplines ranging from fundamental science to applied/in-ser- vice engineering. The Hydromechanics Department researches hull forms, pro-pulsion and ship dynamics to provide the foundation for new ship and subma- rine designs. In delivering his keynote address as the Ògrand openingÓ ceremony for the upgraded facility, Dr. John Holdren, director of the White House OfÞ ce of Science and Technology Policy Saluted Carderock for its spectrum of work from fundamental science to direct technical support of Navy acquisition programs and operational units, to include work to reduce acquisition and operating costs.Holdren acknowledged that global competitors are focusing on science and engineering, making it vitally important for America to Òmaintain the intensity of our own investments [in science and technology] so we can keep our national security science and technology base healthy and ready to respond whenever needed.Ó The MASK is named for the leading American hydrodynamicist of the 20th century, Harold E. Saunders, who was also a Navy captain and a member of two of Admiral ByrdÕs expeditions to the Antarctic. Members of the Saunders family were present at the ceremony.
