On December 7, 1941, Mangrum, then with VMSB-232, was at Pearl Harbor. Twenty of his squadron's SBD Dauntless dive bombers were destroyed on the tarmac at Marine Corps Air Station Ewa. During the early months of the Guadalcanal Campaign in 1942, he commanded VMSB-232, the first scout bomber squadron to join the Cactus Air Force. On August 20, Mangrum's dozen Douglas SBD Dauntless dive bombers launched from the deck of the USS Long Island (CVE-1) escorted by Grumman F4F Wildcats from Maj John Smith's VMF-223 to become the first Marine planes to land on the new airfield that had just been constructed. They were met on the tarmac by Alexander Vandegrift then commanding general of the 1st Marine Division. He was awarded the Navy Cross and Distinguished Flying Cross for successful attacks on Japanese naval units during engagements such as the Battle of the Eastern Solomons. During his first 29 days ashore during the battle, Mangrum flew 28 missions including ten strikes, eight searches and seven reconnaissance patrols in support of both ground and naval forces.
Mangrum left Guadalcanal on October 14, 1942, as the only pilot from his squadron able to walk away from Henderson Field. Seven had been killed, four were wounded and all of the others had been flown out for hospitalization. Returning to the United States, he served as commanding officer, Cadet Regiment at Naval Air Training Center, Corpus Christi, Texas from 1943 to 1944.

Mangrum was awarded a second Legion of Merit with Combat "V" during the Korean War, 1951, for duty as commanding officer, Marine Aircraft Group 12. Later, he was awarded the Navy Commendation Medal with Combat "V" as First Marine Aircraft Wing liaison officer to Headquarters, 5th Air Force in Seoul, Korea, in 1952.

On October 1, 1965, General Mangrum succeeded to the title "Gray Eagle" of Naval Aviation, becoming the first Marine Aviator to attain this distinction. The "Gray Eagle" is the earliest designated aviator on active duty in the Navy and Marine Corps. Mangrum was designated a Naval Aviator in August 1929.

### Navy Cross citation

    The President of the United States takes pleasure in presenting the Navy Cross to Richard C. Mangrum (0-4412), Lieutenant Colonel, U.S. Marine Corps, for extraordinary heroism and distinguished service in the line of his profession Leader and as a Pilot in Marine Scout-Bombing Squadron Two Hundred Thirty-Two (VMSB-232), Marine Air Group Twenty-Three (MAG-23), First Marine Aircraft Wing, in aerial combat with enemy Japanese forces in the Solomon Islands Area from 20 August 1942 to 15 September 1942. Commanding a Navy and Marine Corps striking force of sixteen planes, Lieutenant Colonel Mangrum intercepted and attacked an enemy task force of surface craft which was planning to attack our beachhead on Guadalcanal. Striking with lightning-like precision, his planes dropped all their bombs before the enemy surface craft could initiate evasive action, making a direct hit on the largest transport, blasting men and debris into the water, and setting the ship on fire. After a cruiser was also hit and left burning, later to disappear, the Japanese were forced to withdraw and abandon their mission. Lieutenant Colonel Mangrum's high quality of leadership and the aggressive spirit of his command in action contributed in large measure to the success achieved by our forces and were in keeping with the highest traditions of the United States Naval Service.
