Pearl harbor, английский
After the successful british naval air raid on taranto, japanese admiral isoroku yamamoto planned a similar attack on the u.s. naval base at pearl harbor. the raid, launched on 7th december 1941, from 274 miles off the coast of oahu, achieved complete surprise. the aircraft came in two waves, at 7:53 and 8:55. by 9:55 it was all over. three hours later all surviving aircraft had landed and the carriers were heading back to japan. it is instructive to compare the two actions. • italy was in a state of war and taranto received advance warning of the approaching strike, whereas pearl harbor’s defenses were unmanned, unsuspecting, and on peacetime sunday routines. • the british attack had been mounted by a mere twenty-one obsolete open-cockpit fabric biplanes, launched from a lone carrier, with only two being shot down. japan launched 354 state-of-the-art aircraft from six carriers, and lost 29. • damage inflicted was not proportional to the number of aircraft. half of italy’s six battleships were sunk at their moorings, as were three cruisers. japanese aircraft also sank three battleships (arizona was claimed by a midget submarine), crippled four more, and sank three cruisers. • at taranto, valuable oil storage tanks were set ablaze; but at pearl four-and-a-half million tons of fuel storage were not even targeted—neither were the huge supply dumps, dry-docks, and precision machine shops, which would allow the u.s. navy to make a rapid recovery. • in both operations, nearby airfields and float plane bases were attacked, but the scale of that assault was greater at pearl. taranto was a strategic success, while pearl harbor was a failure. in the mediterranean, where gunpower was still a major factor, the loss of fifty percent of its capital ships was a crippling blow to regia marina, which seldom ventured out of harbor again. in the pacific, however, naval aviation would be the supreme weapon, and not one american carrier had been in port at the time of the attack.
