Military Sealift Command’s Special Mission program supports worldwide oceanographic programs with six ships that perform acoustical, biological, physical and geophysical surveys. These ships gather data that provides much of the military’s information on the ocean environment. The collected data helps to improve technology in undersea warfare and enemy ship detection. The oceanographic and hydrographic survey ships’ multibeam, wide-angle precision sonar systems make it possible to continuously chart a broad strip of ocean floor. Survey ships have charted three-fourths of the world’s coastlines, making it easier for navigators to find their way along both well-traveled and not-so-familiar shipping routes.
