US Navy submarine commander and Medal of Honor recipient (1906–1944)
In May 1937, he was assigned as an aide to the executive officer at Naval Air Station, Pensacola, Florida (NAS Pensacola). While there, in June 1938, he was promoted to lieutenant. In the summer of 1939, he was assigned as the executive officer (first officer) on board Reuben James. In April 1941, he reported to Experimental Division One for duty as the prospective commanding officer (PCO) of S 20 to support at sea experiments off New London. He commanded S 20 for two years, serving aboard at the United States' entry into World War II.

Harder left Pearl Harbor on her first war patrol on June 7, 1943, bound for the coast of southern Honshu. In Dealey's first attack on a two ship enemy convoy late on the night of June 21, the submarine was driven down deep by an aggressive enemy escort and crashed into the muddy bottom – an inauspicious beginning, even though it now appears that one enemy target may have been damaged. Dealey backed the submarine out of the mud, and two nights later had his first real success in torpedoing the Japanese seaplane tender Sagara Maru (7,000 tons) and crippling the enemy ship so badly that it was beached on the Japanese mainland and abandoned as a total loss. Over the next four days, Dealey made seven attacks on three different enemy ship convoys, but post war analysis credits him only with possible damage to one enemy ship.</blockquote>

Continuing his war patrol, Dealey next scored his first of four successes against the toughest target of all – an enemy Japanese destroyer. Spotted by an enemy aircraft north of the Western Carolines on April 13, 1944, Harder became the quarry of a patrolling enemy destroyer Ikazuchi, which closed to within before Dealey fired a spread of torpedoes. The destroyer sank within five minutes. Dealey's ensuing contact report quickly became famous: "Expended four torpedoes and one Jap destroyer". Four days later, Dealey also sank Matsue Maru (7,000 tons) near Woleai – then surfaced again near the island on April 20 to bombard the beleaguered Japanese garrison with his submarine's deck gun. Harder ended its fourth war patrol at Fremantle, Australia, on May 3, 1944. Hayanami blew up virtually overhead, and one of her sisters subjected Harder to a two hour depth charge attack. By 17.30, there were eight hunting him. Dealey slipped away. Harder transited the Sibutu Passage to pick up the guerrilla force on the night of June 8/9 and headed back early the next day. Ultimately, Christie agreed Dealey could take Harder out for one more patrol, her sixth. Dealey left Fremantle on August 5, 1944, commanding a three sub wolfpack, joined by Haddo (Chester Nimitz, Jr.) and Hake (Frank E. Haylor, who replaced John Broach). Their objective was the destruction of Japanese shipping off the west coast of the Philippines, south of the Luzon Strait. After being informed (thanks to a contact report from William Kinsella's Ray, himself guided by Ultra) holed up in Paluan Bay in northern Mindoro, Harder and Haddo joined three other U. S. submarines (Guitarro, Raton, and Kinsella's Ray, with only four torpedoes remaining), all under Dealey's command (as senior officer present afloat). When the enemy convoy sortied at 05.45 on August 21, It became apparent the enemy minesweeper had been successful on August 24 in ending their extraordinary run. Indeed, after the war, Japanese records showed an antisubmarine attack that morning off Caiman Point had resulted in oil, wood chips, and cork floating in the vicinity. Dealey's death produced waves of "profound shock" and grief through the entire Submarine Force. Dealey's loss is still blamed on fatigue by some, such as Lynch. It widened the gulf between Christie and Lockwood. In addition, Christie's attempt to nominate Dealey for a second Medal of Honor was thwarted by Admiral Thomas C. Kinkaid, who argued the award of an Army Distinguished Service Cross for the patrol precluded any Navy decoration. In the final analysis, Dealey had sunk 16 enemy ships, with total tonnage of 54,002 tons (according to the postwar accounting – enough to make him number five among U. S. submarine skippers in World War II.

Perhaps smarting from his decision to allow Dealey to undertake a sixth war patrol at a time when several colleagues thought he was tired and overly fatigued, RADM Christie nominated Dealey for a posthumous Medal of Honor immediately after the loss was reported. This action became mired in a controversy. General Douglas MacArthur had previously awarded the Army Distinguished Service Cross to Dealey for his prior accomplishments in the theater. Thomas Kinkaid, COMSEVENTHFLT (MacArthur's naval commander) disapproved Dealey for the Medal of Honor on the grounds that he had already been honored adequately. This dispute was one of several that led to growing personal animosity between Christie and Kinkaid, culminating in Kinkaid's relieving Christie in December 1944. Christie then returned to Washington, finally receiving MacArthur's support for the Medal of Honor which was presented posthumously to Dealey's wife, Edwina, on August 29, 1945.

Commander Dealey was awarded the Medal of Honor for Harder's fifth war patrol and was posthumously awarded the Silver Star for gallantry in action during Harder's sixth war patrol. In 1953, Dealey was named in his honor; she was the lead ship of her class of destroyer escort. There is a plaque in Dealey's honor in the Science Place in Fair Park, Dallas, Texas. Sam Dealey Drive in Dallas, Texas was named after him.
