The opening ceremony was presided over by Shi Xiaofeng, director of the Science and Technology Committee of the 7th Institute of CSSC. Li Guoan, secretary and Vice President of China Society of Shipbuilding and Engineering, Professor Song Baowei, vice president of Northwestern Polytechnical University, and Wang Zhong, director and Deputy Secretary of the 7th Party Committee of CSSC delivered speeches in turn.

Li Guoan, on behalf of the China Society of Naval Architecture and Engineering, extended a warm welcome to the delegates attending the forum and thanked the leaders and experts who cared for and supported the work of the Society. The forum will build a communication platform to promote integration and progress, take the development of disciplines and science and technology in this field as its own responsibility, aim to promote the further development of unmanned underwater system technology in China, promote the development and application of new technologies and new products, and strengthen the integration and communication of  Unmanned Undersea systems and related industries. The Chinese Society of Shipbuilding and Engineering is committed to building a first-class society with Chinese characteristics during the 14th Five-Year Plan period, and actively carrying out various work to help build China into a maritime power.

Vice President Song Baowei said that the " Unmanned Undersea system Technology Summit Forum" is an influential academic summit forum brand at home and abroad, Northwestern Polytechnical University has long adhered to independent innovation in science and technology, Keep up with the country's major strategic needs and national defense construction needs, Give full play to the characteristic advantages of the "three flights" of aviation, aerospace and navigation, Has made important contributions to national defense science and technology and the development of national economy, It has trained a group of leading talents with national feelings, the pursuit of excellence and leading the future, Has created a number of  Unmanned Undersea system equipment to serve the Marine strategy, This forum, because the online and control of epidemic prevention and offline, Will not affect the quality of the wonderful academic reports brought by experts and scholars, Will certainly enhance the collision of ideas in the academic fields in different directions, Promoting exchanges and cooperation, Promoting technological progress, To make new contributions to the national scientific and technological development and economic construction.

Wang Zhong director stressed that under the background of a new round of technological revolution accelerating, unmanned, intelligent has become an important direction of the future development of science and technology, the  Unmanned Undersea system is an important part of modern Marine equipment, is a new concept of underwater attack and defense equipment technology the most widely used field, has important strategic significance. Ship group 75 is committed to explore underwater and related technology pioneer frontier development exploration, aimed at the construction of Marine power vision, actively response to the national group company high quality development, the peak BBS into underwater defense original ideas, hope the members extensive exchanges, learn from each other, enhance technical cooperation, common progress hand in hand.

The special report is divided into two halves: morning and afternoon, presided over by Director Shi Xiaofeng and President Pan Guang respectively, with a total of 12 special reports. Academician Qiu Zhiming of the Chinese Academy of Navy entitled "Progress of Cross-domain Collaborative Research of Marine Robot" (reported by assistant Meng Xiangyao); Professor Sun Dajun of Harbin Engineering University gave a report entitled "Thinking on the Development of Hydroacoustic Collaborative Detection Technology in the Background of Intelligent Era"; Professor Ge Tong of Shanghai Jiao Tong University made a report entitled "Siyuan" 10,000-meter unmanned remote control submersible "; Professor Zou Li of Dalian University of Technology delivered a report entitled "Key Technologies and Research Progress of Deep-sea Mineral Resources Development"; Researcher Duan Hao from the 75th Institute of CSSC delivered a report entitled "Discussion on several Issues in UUV Overall Extreme Plan and Efficiency Evaluation"; Professor Pan Guang, dean of Navigation School of Northwestern Polytechnical University, delivered a report entitled "Research Progress of submersible Control Technology of Manta Bipoque"; Pengcheng Laboratory Broadband Communication Department underwater communication Technology Research Institute engineer Liu Hengli made a report entitled "Marine unmanned system is a new future of intelligent ship"; Cao Juliang, a researcher of National University of Defense Technology, delivered a report entitled "Thinking on Underwater navigation Technology for Combat Application"; Professor Bai Bofeng of Xi'an Jiaotong University delivered a report entitled "Closed-loop Power Technology and Application prospect of underwater supercritical fluid"; Professor Liu Songzuo of Harbin Engineering University made a report entitled "Environmental adaptive multi-system underwater acoustic communication technology"; Professor Sun Haixin of Xiamen University delivered a report entitled "Based on single-source Point Collaborative Navigation System"; Professor Xu Minyi of Dalian Maritime University delivered a report entitled "Underwater energy collection based on flexible friction nanogenerator".

BBS academic exchange link by  Unmanned Undersea systems executive editor of wei-jun CAI researcher, from xi'an jiaotong university, naval engineering university, Harbin industrial university, aerospace institute 513 institute, Chinese group 705 institute, China group 760 research institute, sea wind power co., LTD. 7 universities, research institutes of 13 young scholars report himself in unmanned system related field the latest research progress.

Despite the limited time, the wonderful academic reports of experts and scholars introduced the latest and cutting-edge technological development in the field of  Unmanned Undersea systems, expanded their vision, strengthened the academic exchanges and interaction in the industry, and injected fresh vitality into the development of this field.
