ASNE is the leading professional engineering society for engineers, scientists and allied professionals who conceive, design, develop, test, construct, outfit, operate and maintain complex naval and maritime ships, submarines and aircraft and their associated systems and subsystems.  ASNE also serves the educators who train the professionals, researchers who develop related technology, and students who are preparing for the profession.  Society activities provide support for the U.S. Navy; U.S. Coast Guard; U.S. Marine Corps; U.S. Merchant Marine and U.S. Army.

ASNE is the seventh oldest technical society in the United States.  It was founded in 1888 by a group of naval engineering pioneers, most of them officers of the U.S. Navy's Engineering Corps, who sought a unified approach to their profession in order to make the most of new advances in technology. The purposes of ASNE are:           

  • to advance the knowledge and practice of naval engineering in public and private applications and operations,
  • to enhance the professionalism and well-being of members, and
  • to promote naval engineering as a career field.

For 125 years, the Society’s objectives have been strengthened and preserved to meet the changing needs of a time-honored profession. Today ASNE conducts a variety of technical meetings and symposia, publishes the highly regarded Naval Engineers Journal and a number of other technical proceedings and publications, and fosters professional development and technical information exchange through technical committees, local section activities and cooperative efforts with government organizations and other professional societies.

The Society's annual meeting, ASNE Day, is typically held in February of each year in the Washington, DC, area. The meeting features major addresses by high level industry and government leaders and panel discussions by leading members of the profession.  It also includes presentation and discussion of technical papers on a variety of timely naval engineering topics, presentation of the Society's prestigious annual awards and a large exposition with government and industry exhibits covering the full spectrum of naval engineering technology. ASNE Day is highlighted by the Society’s annual Honors Gala, attended by hundreds of executives and senior managers from both government and industry.

Our website is designed to not only serve our members, but also to support scholars, students and others interested in the varied field of naval engineering.  We welcome your suggestions on ways we can improve your experience. 

Dr. Yun-Fan Hwang

Award: Solberg Award
Year: 1991
Dr. Yun-Fan Hwang
For his significant contribution to naval engineering as set forth in the following CITATION:

Dr. Yun-Fan Hwang has been a recognized leader in the development of an understanding of hydroacoustic noise generation mechanisms and noise due to the interaction of an external water flow with the ship's hull. His efforts have led to innovative methods aimed at reducing the noise radiated by a ship and the noise generated by a ship that would interfere with its own sonar performance. The technologies developed by Dr. Hwang's group include quiet sonar dome designs, techniques to reduce flow noise affecting sonar arrays, innovative composite structure designs to minimize acoustic radiation, and fiber optic hydrophones that do not respond to flow induced noise.

Dr. Hwang has led the Navy's efforts in developing computer codes for predicting the flow noise affecting sonars, and radiated and platform noises due to the excitation of hull components by the external turbulent boundary layer. Computer codes developed by Dr. Hwang allowed evaluation of multiple candidate sonar dome designs and mounting schemes without the costly and time consuming process of fabrication and experimental evaluation of each candidate design. As a result of his work, the Navy is assured of having an acoustically superior sonar dome design that will meet the operational goals of Seawolf.

Dr. Hwang has recently assembled a team of interdisciplinary experts to develop a light weight composite of multi layered sandwich materials that will have optimum acoustic parameters. By emphasizing the wave propagation aspects of the sandwich material, the team has taken a new approach for developing composites for structural acoustics. The result of this work will provide an improved sonar dome design that can further enhance the operational capability of existing and future submarines.

Dr. Hwang's efforts have resulted in the advancement of fundamental understanding in the areas of structural acoustics, flow and structure interactions, and hydroacoustics. His work has led to the development of new design tools, material, and design considerations that are being incorporated into submarines and surface ships, especially the SSN 21 Seawolf, to improve their acoustic performance. His exceptional ability to apply his theoretical understanding to rapidly solve engineering problems has provided savings in time and cost on numerous occasions. He has been a mentor, teacher and colleague to a whole new generation of young scientists and engineers and is most worthy to receive the Solberg Award for 1991.
