The Navy Cross is the United States military's second-highest decoration awarded for valor in combat.
 The Navy Cross is awarded primarily to a member of the United States Navy, U.S. Marine Corps, and the U.S. Coast Guard (when operating under the Department of the Navy) for extraordinary heroism.
 The medal is equivalent to the Army Distinguished Service Cross, the Air Force Cross, and the Coast Guard Cross.
George Cregan (December 11, 1885 – June 30, 1969) was a commander in the United States Navy.
 He was a recipient of the Medal of Honor, the nation's highest military award for valor, for his role in the United States occupation of Veracruz when he was a coxswain.
 He was also awarded the Navy Cross, the second highest military decoration awarded to a member of the United States Navy, U.S. Marine Corps and to members of the Coast Guard for extraordinary heroism.
 He received the Navy Cross for his participation in the 1929 salvage operation of the submarine USS S-4.
Ralph McMaster Rich (22 January 1916 - 18 June 1942) was an aviator of the United States Navy during World War II.
USS "Rich" (DE-695) was a "Buckley"-class destroyer escort , the first United States Navy ship named in honor of Lieutenant (j.g.) Ralph M. Rich (1916–1942) who was awarded the Navy Cross for his leadership as a fighter pilot off "Enterprise" during the Battle of Midway.
USS "Holton" (DE-703), a "Buckley"-class destroyer escort of the United States Navy, was named after Ralph Lee Holton, who was born on 19 September 1918, and graduated from the Naval Academy in December 1941.
 He was awarded the Navy Cross for his valiant rescue work aiding survivors of the stricken aircraft carrier "Lexington" on 8 May 1942 in the Battle of the Coral Sea.
 As officer-in-charge of a boat detailed to rescue survivors from the burning carrier, Ensign Holton, under a hail of flaming debris from bombs, ammunition, and gasoline exploding on "Lexington", persistently returned to the stricken ship and thus effected a series of daring rescues in which he saved the lives of many members of the ship's crew who otherwise would have been lost.
 Less than a month later, on 6 June, Ensign Holton was reported missing and presumed dead as his ship, the destroyer "Hammann" , was sunk by a Japanese submarine during the Battle of Midway while assisting the aircraft carrier "Yorktown" .
Rear Admiral Frederick Lois Riefkohl (February 27, 1889 – September 1969), a native of Maunabo, Puerto Rico, was an officer in the United States Navy and the first Puerto Rican to graduate from the United States Naval Academy and to be awarded the Navy Cross.

 He was a World War I Navy Cross recipient who served as Captain of the USS "Vincennes" during World War II.
USS "Rich" (DD-820/DDE-820) was a "Gearing"-class destroyer in the United States Navy during the Korean War and the Vietnam War.
 She was the second ship named in honor of Lieutenant (j.g.) Ralph McMaster Rich (1916–1942), who was awarded the Navy Cross for his leadership as a fighter pilot off the USS "Enterprise" (CV-6) during the Battle of Midway.
Doris "Dorie" Miller (October 12, 1919November 24, 1943) was a Messman Third Class that the United States Navy noted for his bravery during the attack on Pearl Harbor on December 7, 1941.
 He was the first African American to be awarded the Navy Cross, the third highest honor awarded by the US Navy at the time, after the Medal of Honor and the Navy Distinguished Service Medal.
 The Navy Cross now precedes the Navy Distinguished Service Medal.
 Miller's acts were heavily publicized in the black press, making him an iconic emblem of the war for black Americans.
 Nearly two years after Pearl Harbor, he was killed in action when "Liscome Bay" was sunk by a Japanese submarine during the Battle of Makin.
USS "Enterprise" (CV-6), was the seventh U.S. Navy vessel to bear the name.
 Colloquially called "the Big E", she was the sixth aircraft carrier of the United States Navy.
 A "Yorktown"-class carrier, she was launched in 1936 and was one of only three American carriers commissioned before World War II to survive the war (the others being "Saratoga" and "Ranger" ).
 She participated in more major actions of the war against Japan than any other United States ship.
 These actions included the Attack on Pearl Harbor (18 dive bombers of VS-6 were over the harbor, 6 were shot down with a loss of eleven men, making her the only American Aircraft carrier with men at Pearl Harbor during the Attack and the first to receive casualties during the Pacific War), the Battle of Midway, the Battle of the Eastern Solomons, the Battle of the Santa Cruz Islands, various other air-sea engagements during the Guadalcanal Campaign, the Battle of the Philippine Sea, and the Battle of Leyte Gulf.
 "Enterprise" earned 20 battle stars, the most for any U.S. warship in World War II, and was the most decorated U.S. ship of World War II, She is also the first American ship to sink an enemy vessel during the Pacific War, the sole surviving pilot of the six planes shot down over Pearl Harbor sank Japanese submarine I-70 on 10 December 1941.
 On three occasions during the Pacific War, the Japanese announced that she had been sunk in battle, resulting in her being named "The Grey Ghost".
USS "Douglas H. Fox" (DD-779) an "Allen M. Sumner"-class destroyer , was named in honor of Lieutenant Commander Douglas H. Fox, the commanding officer of the destroyer USS "Barton" , who went down with his ship when she was torpedoed and sunk in the naval battle of Guadalcanal on 13 November 1942.
 Fox was posthumously awarded the Navy Cross for his contribution to the defeat of a superior enemy force in this battle, and was later awarded a Gold Star in lieu of a second Navy Cross for earlier actions on 26 and 30 October and 3 November, when he rescued survivors of the aircraft carrier USS "Hornet" under hazardous conditions.
