Hydromechanics Laboratory
Since 1975, the Naval Academy Hydromechanics Laboratory (NAHL) has supported a wide variety of activities, including core/elective courses, independent research, faculty research, and sponsored testing.  NAHL continues to maintain a proud tradition of directly supporting the fields of naval architecture/marine engineering and ocean engineering.
Facility History

NAHL was officially opened in the basement of Rickover Hall in September 1976, replacing previous experimental facilities in the Isherwood Hall Ship Hydromechanics Laboratory.  Of particular note, the 380 FT Towing Tank was formally dedicated in a ceremony held on August 24, 1977.  Professor Bruce Johnson, the first NAHL Director, was instrumental to the design, construction/fabrication, and subsequent operation of the 380 FT Towing Tank.  The following documents provide additional detail about the extensive history of NAHL's world-class engineering systems:

Naval Architecture Major (ENA/ENM/ENMH) Class Photos

Beginning with the Class of 1972, the Naval Architecture (ENA/ENM/ENMH) major has allowed midshipmen to explore the fundamental aspects of ship/submarine design.  The following class photos document the history of naval architects at USNA:

1972 1973 1974 1975 1976 1977 1978 1979
1980 1981 1982 1983 1984 1985 1986 1987 1988 1989
1990 1991 1992 1993 1994 1995 1996 1997 1998 1999
2000 2001 2002 2003 2004 2005 2006 2007 2008 2009
2010 2011 2012 2013 2014 2015 2016 2017 2018 2019
2020 2021

NAHL has served as the very foundation of naval architecture education at USNA.  Through hands-on modeling/experimentation, including tow-tank testing, graduates of the ENA/ENM/ENMH major have emerged as more successful (and technically competent) engineers, program/project managers, and leaders.

Student Research & Publications

NAHL has proudly supported USNA's prestigious Trident Scholar Program.  The following Trident Scholars have leveraged NAHL facilities, equipment/instrumentation, and expertise for their respective research:
