As a commander of the engineers, he directed and managed all Navy construction programs. This included Navy military construction in Vietnam, the largest single construction program in military history, according to Navy sources.

During World War II he commanded the amphibious seabees of the 128th Naval Construction Battalion in the Philippines and Okinawa.

Husband received the Bronze Star with Combat V "for meritorious causeway group of the Joint Expeditionary Force during operations achievement as commander potoon causeway group of the Joint Expenditionary Force during operations against enemy Japanese forces on Okinawa, from April 1 to 25, 1943." The citation added that he had directed the construction and maintenance of the pontoon causeway piers despite adverse weather conditions and enemy air attacks.

He held a number of positions with the Navy engineers both here and abroad after the war.

Adm. Husband was born in Troy, N.Y. and graduated from the Naval Academy at Annapolis in the class of 1935. He later earned a master's degree in civil engineering from Rensselaer Polytechnic Insititute and was a graduate of the advance management program at Harvard University.

He joined the Navy engineers in 1940.

Following his retirement from the Navy Adm. Husband was vice president for construction for Consolidated Edison Co. of New York from 1969 to 1972. Since then he had worked with a Provicence, R.I., architect and engineering firm as a consultant.

In addition to the Bronze Star, he also held the Legion of Merit and numerous medals and ribbons.

Adm. Husband was a past president of the Society of American Military Engineers, a fellow of the American Society of Civil Engineers and was a member of both the American Insititute of Consulting Engineers, and the Nadoal Panel of the American Arbitration Association.

He is survived by his wife, Mary H., of the home in Old Saybrook. Conn.
