It is important to learn from our experiences …

“The aircraft was invented in 1903 and, almost immediately, the military started to look at how to use the technology in combat. But different military branches from different nations moved at different speeds, and many navies considered planes an observation platform and nothing more.”

“In World War I, pilots bombed enemy targets by throwing munitions from their planes, but aerial bombing was still considered a stunt by many, and the U.S. Navy brass was convinced that airplanes weren’t a threat to their capital ships.” (Nye)

“Between the wars, aviation pioneers tried to get the Navy and Army to understand how important planes would be in the next war. Army Gen. William ‘Billy’ Mitchell had some success in 1921 when his men sank the captured German battleship Ostrfriesland in a test.” (Nye)

“[F]rom 1923 to 1940, the Navy ran a series of exercises, collectively called the Navy Fleet Problems, that provided opportunities to test new technology, revise outdated doctrine, prepare for future conflict, and advance a common understanding of naval operations.”

“The fact that the Navy learned lessons in areas such as carrier aviation and submarine tactics with little danger to ships, resources, or personnel made the exercises noteworthy.”

“The Fleet Problems represented a unique period when Admirals, those at the highest level of naval command, critiqued their commanders in an open forum to improve the fleet. Likewise, the commanders, motivated by the same reasons, also felt free to point out institutional deficiencies.” (Sun, US Navy Fleet Problems)

Then … “Lights out, radios silenced, two carriers and their escorts slipped through the night, hiding in squalls and dark clouds. Before dawn, they struck.”

“Fighters snarled across the decks, then scout/attack aircraft, then dive bombers, then torpedo planes. Flashing blue flames, they banked to the southwest toward Oahu. It was a Sunday, and all of Hawaii slept.”

“Below lay Pearl Harbor.”

“The fighters dove first. They demolished aircraft on the ground, knocked out guns and pinned officers and men inside their barracks.”

“Then came the bombers and torpedo planes. They sank every battleship and cruiser in the harbor. ‘Everything went beautifully and according to plan’” an officer wrote afterward. ‘Our squadrons struck their targets shortly after it got light, taking them all by complete surprise.’”

“The date was Sunday, the seventh. But the month was February. And the year was 1932. The attacking carriers were the Saratoga and the Lexington. The fighters were Boeing-built U.S. F-4Bs. And the dive bombers were BM-1s. The sneak attack was commanded by of the U.S. Navy.”

“It was just an exercise.” (LA Times)

“Fleet Problem Number 13 was a mock attack by a ‘militaristic, Asian, island nation against the military base at Pearl Harbor.’”

“The exercise was designed to test Pearl’s defenses and assess its vulnerability to an attack.  The attacking force was under the command of Rear Admiral Harry Yarnell.”

“The admiral was a qualified naval aviator, one of the few admirals to have earned his aviator wings at a time when battleship command was still the path to promotions.”

“In 1927, he took command of the aircraft carrier Saratoga and was instrumental in developing carrier tactics. At the time, carriers were classified as ‘fleet scouting elements.’ They were not valued as capital ships and were considered expendable.”

“Yarnell maintained that Japan ‘had always started operations by attacking before a declaration of war.’ Accordingly, he designed an attack plan that utilized carrier aviation to launch a surprise attack on Pearl Harbor.”

“Pearl’s defenders had anticipated that Yarnell would attack with his battleships. Instead, he left his battleships behind and advanced with the carriers Saratoga and Lexington to a point north-northeast of Hawaii.”

“At dawn, on Sunday February 7, 1932, Yarnell launched his attack with a force of 152 planes from the two carriers. His attack force first attacked the airfields and then proceeded to attack the ships along battleship row.”

“Yarnell achieved total surprise. The airfields were put out of commission, with not a single plane getting airborne during the attack. The attacking force scored multiple hits, they dropped sacks of white flour to simulate bombs, on the battleships.”  (Military-com)

“In 1938, the same wargames were being played again to test Pearl Habor’s defenses. The attacking force was led by Admiral Ernest King, and Admiral Yarnell was working in the background to run the experiment a second time.”

“King took a single aircraft carrier escorted by destroyers to attack Pearl Harbor from the air. Coming in over the Koolau Range, he surprised the military base and won a decisive victory — just as Admiral Yarnell had done so in 1932.”

“As WWII got underway in the Pacific, Japan knew that it could not fend off a full-on assault by the U.S. Navy if the U.S. entered the war. Instead, they needed to launch a pre-emptive strike and hobble the U.S.’s ability to interfere with Japanese operations in the Pacific.”

“Thus, on December 7th, 1941, Japan’s Admiral Yamamoto pulled out the same military plans that Admiral Yarnell used almost 10 years before and launched his own assault on Pearl Harbor. This time, however, his planes would not be carrying ‘flour bombs’ and flares.”

“That Sunday morning, Yamamoto’s planes burst through a wall of clouds over the Koolau Range — and its fighters strafed the U.S. airfields before bombers descended on the island – and only then did the U.S. Navy accept that it should have paid heed to Admirals Yarnell and King when slight embarrassment was the only price it needed to pay.”  (Medium)

“Some think it was distinctly edifying to the Japanese, who [after Yarnell’s decisive exercise] executed what Arthur Radford, a young lieutenant commander and an aide to Yarnell, calls ‘almost a perfect duplicate.’”

“To Americans, however, the exercise was hardly edifying enough. Incredibly, the United States never woke up to the fact that Pearl Harbor–and, therefore, America itself–was vulnerable.”

“In 1932, Radford says, when Yarnell crept up on Hawaii and launched his planes, the exercise was ‘pretty well publicized.’ But Americans paid little attention. The nation was in a seminal transition. Provincial, self-indulgent and distracted by the Great Depression, America was struggling to reawaken to the world.” (LA Times)
