1942: When the Seabees were first established, the United States Navy recruited skilled construction workers and taught them how to use advanced base equipment and how to fight. Because they were skilled in their trades, the men were offered petty officer rates based on their experience and their age. However, on December 15, 1942, direct voluntary enlistment in the Seabees was ended in compliance with a Presidential Order requiring all the military services to obtain their manpower through Selective Service. By that time, about 60 battalions had been assembled.

1944: One of the heroes of the World War II was Seabee Machinist Mate 3rd Class Malcolm Peppo of the 113th NCB. While unloading stores from an LST during the assault on Mindanao, Philippine Islands, Peppo’s ship was attacked by a Japanese kamikaze plane. Because the ship was being unloaded, its bow doors were open and its ramp was down, making it helpless to maneuver. When the anti-aircraft gun crew looked up and saw the suicide plane headed straight for the beached vessel, the men instinctively abandoned their positions and scattered. Peppo, however, jumped into the vacated gun emplacement and fired at the oncoming plane until it crashed. For his courageous actions, Peppo was awarded the Silver Star.
