Senior leader McDonald's career led him to the highest levels of the
United States Navy's command structure. He attended the
National Defense University's
National War College, graduating with the class of 1969. In 1972, as a
rear admiral, McDonald was assigned as the carrier group commander. He later served as deputy chief of Naval Personnel in
Washington, D.C., in 1975. In 1982, McDonald was appointed
Supreme Allied Commander Atlantic (SACLANT), one of two
supreme commanders of the
North Atlantic Treaty Organization. At the same time, he assumed command of the
U.S. Atlantic Command (CINCLANT) and
U.S. Atlantic Fleet (CINCLANTFLT). In 1983, McDonald, in his role as CINCLANT, was placed in overall command of Operation Urgent Fury—the invasion of Grenada to rescue U.S. nationals. He later summed up the success of the operation in an address before the
House Armed Services Committee. Photo) McDonald was the last
