On December 7, 1941, Japanese torpedoes and bombs devastated Hawaii’s warships and air fields. The “Weapons Wall” at Pacific Aviation Museum has full-size models of three of these weapons—the ones used in the first wave of the attack. The wall also shows the aircraft that carried different types of ordnance during the first wave.
This article goes beyond the information shown on the Weapons Wall, to look at the bombs used in the second wave. The Japanese Kates and Vals of the second wave delivered different types of bombs than they delivered in the first wave—including two types of bombs not used in the first wave. Table 1 summarizes basic data about the torpedoes and four types of bombs used during the attack, and about the aircraft that delivered each weapon during the two waves.
