Japanese war planners soon recognized that “crucial targets” such as the Pearl Harbor shipyards, maintenance shops and fuel-reserve facilities had been largely undamaged, according to an exhibit at the Pacific Aviation Museum in Honolulu. From those shipyards America mobilized an astoundingly speedy and effective effort to repair vessels damaged in the December attack.
The Japanese hoped to stymie that salvage work with Operation K, a bombing raid using the first two prototypes of the H8K amphibious plane.While extremely successful, the first Japanese raid on Pearl Harbor had left several important targets -- fuel tanks, and dry docks -- undamaged. Three months after the first attack, they launched a second attack comprising of two long range H8K planes, each with four 550 lb bombs.
However, when they got over the target it was clouded in, and they dropped their bombs blindly. One hit a hillside and broke some windows, it is unknown where the other bombs fell.
