Floyd A. Hansen, 77, a retired major general who served as head of the Army Munitions Command before retiring from active duty in 1967, died of congestive heart failure May 24 at Arlington Hospital. He lived in Arlington.

He was head of the Army Munitions Command from 1962 to 1967. During those years, the escalation of the war in Southeast Asia brought enormous demands on the Command. Gen. Hansen directed production operations that exceeded those of World War II, with only one third the number of plants.

Gen. Hansen was a native of Sumas, Wash., and a 1932 graduate of the U.S. Military Academy at West Point. Commissioned in the field artillery, he earned a master's degree at the Massachusetts Institute of Technology and graduated from the Army's Ordnance School at Aberdeen Proving Ground in Maryland. Also before World War II, he helped design ammunition plants.

During the war, he served with the 1st Army in Europe, participating in the Normandy landings on D-Day. After the end of the war in Europe, he transferred to the Southwest Pacific theater as an ordnance officer.

After the war his assignments included a tour with a mission to Venezuela. He also graduated from the National War College and served as supply director in the operations office of the Army deputy chief of staff for logistics.

After retiring from active duty, Gen. Hansen spent about five years as a consultant here to Norris Industries, a manufacturing concern, and what is now Booz-Allen & Hamilton Inc., a consulting organization.

His military decorations included the Distinguished Service Medal and the Legion of Merit. He was a recipient of the West Point Scroll and a member of the Ordnance Hall of Fame. He was a member of the Army Defense Preparedness Association, the Retired Officers Association, and the Army Navy Country Club. He also was active in the Boy Scouts.

Survivors include his wife, Eloise, of Arlington; a daughter, Gail Fox of Bellingham, Wash., and a grandchild.
