John H. Jorgenson, 61, a retired Navy commander who was a heavily decorated flyer in World War II, was found dead March 31 at his home in Alexandria. The Northern Virginia medical examiner's office said he died of a heart attack.

After his retirement from the Navy in 1963, Cmdr. Jorgenson was an official of the National Security Industrial Association in Washington. His duties involved organizing joint government-industry groups to work on antisubmarine programs, satellite communications and aspects of the space program. He went to work on the Friday before his body was found.

A native of Story City, Iowa, Cmdr. Jorgenson attended the University of Minnesota and Iowa State College. He entered the Navy in 1941 and was commissioned and received his pilot's wings at the Naval Air Station at Pensacola, Fla.

During World War II, he was stationed aboard the aircraft carrier Yorktown and fought in the Battle of the Coral Sea, where he won the Navy Cross, the second highest decoration for gallantry, and the Purple Heart medal for wounds. Several weeks later, he flew in the Battle of Midway, where he won a second Navy Cross. The Yorktown, which had been severely damaged at Coral Sea, was sunk at Midway.

Later in the war, Cmdr. Jorgenson was assigned to an amphibious group and took part in the invasions of Iwo Jima and Okinawa. During the Korean conflict, he was an air and naval gunfire liaison officer attached to the First Marine Division.

His peacetime assignments included command of destroyers based at Jacksonville, Fla. He was attached to the staff of the Chief of Naval Operations when he retired.

In addition to his Navy Crosses and the Purple Heart, Cmdr. Jorgenson held three Distinguished Flying Crosses.

Survivors include his wife, Grace Powell Jorgenson of Los Angeles; one daughter, Lori Morgan of Beaver Dam, Va., and three sons, John Harry Jr., of Washington, and James P. and Lewis V., both of Alexandria.
