On February 20, 1942, Lieutenant Edward Henry O’Hare becomes the first United States Navy fighter ace of World War II when he single-handedly attacks a formation of nine medium bombers approaching his aircraft carrier. Even though he has a limited amount of ammunition, he is credited with shooting down five enemy bombers and becomes the first naval aviator recipient of the Medal of Honor in World War II.
O’Hare is born in St. Louis, Missouri on March 13, 1914, the son of Edward Joseph O’Hare and Selma Anna (née Lauth). He is of Irish and German descent. When his parents divorce in 1927, he and his sisters, Patricia and Marilyn, stay with their mother in St. Louis while their father moves to Chicago. His father is a lawyer who works closely with Al Capone before turning against him and helping convict Capone of tax evasion.
O’Hare graduates from the Western Military Academy in 1932. The following year, he goes on to the United States Naval Academy at Annapolis, Maryland. After graduation and is commissioned as an ensign on June 3, 1937, serving two years on the battleship USS New Mexico. In 1939, he starts flight training at Naval Air Station Pensacola in Florida. When he finishes his naval aviation training on May 2, 1940, he is assigned to Fighter Squadron Three (VF-3) on board USS Saratoga.
On Sunday evening, January 11, 1942, as O’Hare and other VF-3 officers eat dinner in the wardroom, the USS Saratoga is damaged by a Japanese torpedo while patrolling southwest of Hawaii. She spends five months in repair on the west coast, so VF-3 squadron transfers to the USS Lexington on January 31.
At 15:42 on February 20, 1942, a jagged vee signal draws the attention of the USS Lexington‘s radar operator. The contact is then lost but reappears at 16:25 forty-seven miles west. O’Hare is one of several pilots launched to intercept nine Japanese Mitsubishi G4M “Betty” bombers from the 4th Kōkūtai‘s 2nd Chutai. His squadmates shoot down eight bombers but he and his wingman, Marion “Duff” Dufilho, are held back in the event of a second attack.
At 16:49, the USS Lexington‘s radar picks up a second formation of “Bettys” from the 4th Kōkūtai’s 1st Chutai, only 12 miles out, on the disengaged side of the task force. With the majority of VF-3 still chasing the 2nd Chutai, only O’Hare and Dufilho are available to intercept.
O’Hare’s initial maneuver is a high-side diving attack from the formation’s starboard side employing deflection shooting. He manages to hit the outside Betty’s right engine and wing fuel tanks. When the stricken aircraft abruptly lurches to starboard, he switches to the next plane up the line. The plane catches fire, but the crew manages to extinguish the flames with a fire-extinguisher. This plane catches up with the group before bomb release.
With two “Bettys” out of formation, O’Hare begins his second firing pass, this time from the port side. His first target is the outside plane. His bullets damage the right engine and left fuel tank, forcing the pilot to dump his bombs and abort his mission. O’Hare then targets another plane which becomes his first definite kill.
As O’Hare begins his third firing pass, again from the port side, the remaining “Bettys” are nearing their bomb release point. He shoots down another plane, leaving the lead plane exposed. His concentrated fire causes the plane’s port engine nacelle to break free from its mountings and fall from the plane. The resulting explosion leaves a gaping hole in the left wing, and the plane falls out of formation.
Shortly afterward, O’Hare makes a fourth firing pass, likely against the plane that had caught fire during his initial pass but runs out of ammunition. Frustrated, he pulls away to allow the ships to fire their anti-aircraft guns. The four surviving bombers drop their ordnance, but all their 250 kg bombs miss. O’Hare believes he has shot down six bombers and damaged a seventh. Captain Frederick C. Sherman later reduces this to five, as four of the reported nine bombers are still overhead when he pulls off.
In fact, O’Hare destroys only three “Bettys.” One of the planes, however, is not yet finished. The command pilot regains enough control to level his damaged plane and attempts to crash it into USS Lexington. He misses and crashes into the water near the carrier at 17:12. Another three “Bettys” are damaged by O’Hare’s attacks. Two safely land at Vunakanau Airfield at 19:50, while the third becomes lost in a storm and eventually ditches at Simpson Harbour at 20:10.
On March 26, O’Hare is greeted at Pearl Harbor by a horde of reporters and radio announcers. Credited with shooting down five bombers, he becomes a flying ace, is selected for promotion to lieutenant commander, and becomes the first naval aviator to receive the Medal of Honor. With President Franklin D. Roosevelt looking on, his wife Rita places the Medal around his neck. After receiving the Medal of Honor, he is described as “modest, inarticulate, humorous, terribly nice and more than a little embarrassed by the whole thing.”
O’Hare receives further decorations later in 1943 for actions in battles near Minamitorishima in August and subsequent missions near Wake Island in October.
O’Hare’s final action takes place on the night of November 26, 1943, while he is leading the U.S. Navy’s first-ever nighttime fighter attack launched from an aircraft carrier. During this encounter with a group of Japanese torpedo bombers, his Grumman F6F Hellcat is shot down. A radio message is sent out, but there is no response. The aircraft is never found. He is declared dead a year later, his widow Rita receiving her husband’s posthumous decorations, a Purple Heart and the Navy Cross on November 26, 1944. On January 27, 1945, the U.S. Navy names a Gearing-class destroyer, USS O’Hare (DD-889), in his honor.
On September 19, 1949, the Chicago-area Orchard Depot Airport is renamed O’Hare International Airport, six years after O’Hare perished. A Grumman F4F Wildcat, in a livery identical to the aircraft flown by O’Hare, is on display in Terminal 2. The display is formally opened on the seventy-fifth anniversary of his Medal of Honor flight.
