The world's oceans below 6,500 meters are presently virtually unexplored. Thesediverse and inaccessible tectonic regimes pose significant questions about a wide range of fundamental problems in the earth and ocean sciences. These regimes include deep areas of active continental margins where major earthquakes are generated and hydrologic exchange occurs between subducted oceanic lithosphere and island arc complexes. Deep access to the seafloor in areas of ultra-slow spreading mid ocean ridges, primarily found in geographic regions of inhospitable weather or ice covered ocean (e.g. Arctic), would be a primary use for such a vehicle. The capability to routinely access the deepest ocean depths also has important implications for a broad range of science and engineering associated with ocean observatory and event response research that will explore 3D and 4D multidisciplinary problems for decades to come. Hybrid ROVs will enable the scientific community to quickly react to ocean floor volcanic and hydrothermal events from a wide range of UNOLS vessels, whereby follow-on experimentscan be designed and implemented based on detailed, first-order mapping and sampling conducted by the 11,000 meter HROV. Moreover, the HROV will provide the United States with fully global capability for search, survey, and recovery missions of national strategic importance.***

世界上6,500米以下的海洋目前几乎没有被探索过。这些深层次的和难以接近的构造体制对地球和海洋科学中广泛的基本问题提出了重大问题。这些机制包括活动大陆边缘的深部区域，在那里发生大地震，并在俯冲的海洋岩石圈和岛弧复合体之间发生水文交换。这种潜水器的主要用途是深入到扩张超缓慢的大洋中脊地区的海底，这些地区主要位于气候恶劣的地理区域或冰层覆盖的海洋（如北极）。常规访问最深海洋深度的能力也对与海洋观测和事件响应研究相关的广泛科学和工程具有重要意义，这些研究将在未来几十年探索3D和4D多学科问题。混合型遥控潜水器将使科学界能够对联合国海洋和海洋法办事处各种船只的洋底火山和热液事件迅速作出反应，从而可以根据11，000米长的“海巡仪”进行的详细的一级测绘和取样设计和实施后续实验。此外，拦截器将为美国提供全面的全球搜索能力，调查，以及具有国家战略重要性的恢复任务。
