Why Japan’s Elite Fighter Pilots Could Not Impose Close Combat On The Corsair

He was alone. He was low. And he had just made a mistake. The mistake was a float plane. Fat, slow, Japanese, cruising a few feet above the swells north of Rabbal on the morning of February 19th, 1944. Lieutenant Ira Kepford had been ordered home 10 minutes earlier. He was 24 years old, a former college halfback out of Moskegan, Michigan, and he could not leave it alone.

One short burst, the float plane went into the sea, and then the sky above him filled up. Roughly 20 Japanese fighters had been sitting up at altitude, watching him do it. They came down together. Four of them broke away and stayed with him, driving him north, away from his field, away from the fuel he had left, out over open water at the exact height where his aircraft was supposed to be at its worst.

Look at that picture honestly because everything depends on it. These were not beginners. This was Rabbal in the winter of 1944 and the men in those cockpits had come out of the most selective flying school on earth in the most maneuverable singleseat fighter of the war. It was four against one. He was low. He was slow.

He was out of position and he was out of friends. They had him and they could not make him fight. That is the strangest fact in the Pacific Air War. Not that Japan’s finest pilots were beaten, that they could not get the other man to stand still long enough to be beaten by. Yokosika on the western shore of Tokyo Bay in the middle of the 1930s.

A naval aviator named Isamu Mochisuki was 28 years old, and he was working on a problem that most of the world’s air forces had already stopped thinking about. He had enlisted in 1925 and finished flight training the following November. In November of 1932, the Navy sent him to the Yokoska Air Group, its test and development unit, the place where the service put the best flyers it had. He stayed four years.

What he built during those four years would still be taught in Japanese fighter schools in the last week of the war. It was a way of losing a man who had gotten behind you. And the trick of it was that it worked by going up. Here is the shape of the thing. You pull hard into a steep climb and start a half loop.

On the way up, you feed in rudder so the aircraft yaws and slides sideways out of the flat plane of that loop instead of staying inside it. At the top, inverted hanging on the propeller with the sea above your head. You are pointed somewhere outside the ark, which is the one place the man behind you is not looking.

Then comes the part that took four years to perfect. Hard opposite rudder, aileron the other way. The controls crossed and fighting each other. The machine twists on its own axis. The turn tightens past anything the geometry says it should allow. And you come down out of that loop with the aircraft that had been sitting on your tail now sitting in front of your guns.

They called it Hinercomi twisting in. Flying it cost the body something in the climb. and the blood drains out of the head and the edges of the world go gray and soft and a pilot learns to grunt against it and keep his eyes open through the tunnel. At the top, the sensation reverses. The straps bite up into the shoulders.

The dust and the loose grit come off the cockpit floor and float past the face. And for one long moment, the engine is turning over with almost nothing to bite into. Everything goes quiet in a way that has nothing to do with sound. Then the cross controls go in, the airframe shutters, and the horizon comes around from a direction that should not be possible.

Mochuki flew it over Tokyo Bay until it stopped being a stunt and started being a reflex. Allied pilots who had it done to them did not have a name for it. They only described what they had seen, which was a fighter that appeared to run out of speed at the top of a loop, hang there for a moment, and then slide sideways out of the sky the way a leaf comes off a branch, and then reappear behind them.

There was a young officer at Yakoska in those same years named Minoru Genda. He watched Mochisuki fly it. He understood immediately what he was looking at, and then he did the thing that mattered more than the invention itself. He helped turn one man’s private trick into a national curriculum. By the end of the 1930s, Hineri Comey was no longer something a clever pilot might happen to know. It was in the syllabus.

Every fighter pilot the Imperial Japanese Navy produced was taught it, drilled in it, and graded on it. Hold on to Genda’s name. He comes back at the end of this story in the last winter of the war with one squadron and one chance to prove that what he and Moisuki built over Tokyo Bay still worked.

Now, here is the part that most tellings of this story skip. It is also the part that decides everything. The Japanese Navy did not call this air combat. They had a general word for air combat. And they had a different far more specific word for the kind of fighting that Hinriikcomi belonged to. That word was kakutosen. It does not really translate as dog fight.

It translates closer to the grappling fight, the wrestling fight. Hand-to- hand. And in Japanese, kakutosen has a direct opposite, a term that describes the other way to use a fighter aircraft. Ichigeki ridatsu. One strike then break away. Hit and run. two words, two philosophies, and a country that built every single thing it owned around the first one while teaching its young men that the second one was what you resorted to when you were not good enough to fight properly.

Think about what a commitment like that looks like once it is bent into metal. The Zero was not a compromise aircraft. It was an argument. Everything that could be taken out of it was taken out. No armor plate behind the pilot’s back. no self-sealing fuel tanks. A structure built as light as the metallurgy of that decade would allow and then lightened again.

In exchange, it could turn inside anything else in the air, climb like something that wanted to leave the planet, and hang on its propeller at speeds where a heavier machine simply stops flying and falls. Its top speed was a little over 330 mph. That number was never the point.

The point was what it could do at half that number. and the men who flew it were built exactly the same way. Everything invested in one specialty. When the Pacific War opened, a fully qualified Imperial Navy fighter pilot carried somewhere around 700 hours in the air. His American counterpart arrived at the fleet with roughly 305. Read those two numbers again slowly.

That gap is not a footnote. That gap is the reason the first six months of the Pacific War went the way they did. They flew in threes. One leader, two wingmen trained together until they could read each other’s intentions without a word, which mattered enormously because Japanese aircraft radios in that period were by every account, including their own, close to useless.

The formation did not need to talk. It had spent 2 years learning how not to have to. So picture what all of that produced. Not simply a good fighter force, a precision instrument optimized for exactly one geometry inside 300 yd below 200 knots in the horizontal turn and in the slow vertical where the man with the lighter aircraft and the better hands wins and then keeps on winning. And it worked.

That is what people forget when they talk about the Zero as an obsolete death trap that burned if you looked at it hard. Before it was any of that, it was the most frightening fighter alive and it proved it on one specific afternoon over China, September 13th, 1940. 13 Zeros led by Lieutenant Saburro Shindo went to Chongqing as escort for a bomber formation.

Somewhere around 34 Chinese fighters came up to meet them. Russian-built machines, biplanes, and monoplanes, both flown by men who had been fighting the Japanese for 3 years and had gotten very good at it. The Japanese pilots came home and reported that they had destroyed 27 of them. All of them, every fighter they had engaged, and that not one zero had been lost.

That number went around the world. military attaches wrote it up. It landed in Washington and in London, and it did what such numbers always do, which is turn into a fact by repetition. Here is the part that did not travel with it. It was not true. Not the way it was told. At least four zeros came home damaged from that fight, which had run for something close to half an hour.

And on the Chinese side, a major named Louis Yim Kun nursed his fighter back to its own field with 48 bullet holes in it, which is a difficult thing to manage in an aircraft that has been officially destroyed. Remember that because it comes back at the very end of this story. Both sides in this war overclaimed from the first day to the last, and most of them did it honestly.

Four men fire at the same aircraft. It rolls over and goes down trailing smoke. Four honest men each write one victory in the log. Nobody lied. The arithmetic simply cannot survive it. But strip the exaggeration out and something real is still standing underneath. There is no version of the numbers in which what happened over Chongqing that afternoon was not a slaughter.

The zero was every bit of what it was said to be. And that was the problem. because being every bit of what it was said to be is exactly what hid the thing nobody had noticed. Go back through all of it. The maneuver, the airframe with the armor deliberately deleted, the three plane section that could speak without radios, the 700 hours, every single element of that system assumes something.

It assumes that the other man will still be there when the turn comes around. That is not a small assumption. That is the assumption. Everything Mochisuki built over Tokyo Bay. Everything a three plane section rehearsed for two years. Everything those 700 hours purchased. Every last piece of it begins working at the instant two aircraft come together.

And it keeps working only for as long as they stay together. Until 1943, nobody in the Imperial Japanese Navy had ever needed to think about that for one simple reason. Nobody had a choice. The early American and British fighters in that theater could not leave. A few could dive away and then had to climb back and try again.

One American officer had worked out a formation that let a slower pair survive an attack by a faster and more agile enemy, and it saved a great many lives, but even that was a method for surviving a fight you could not decline. Every opponent the Imperial Navy had met so far came into the merge and stayed in it because staying was the only thing on the table.

Everything Japan had built since the early 1930s had produced the finest close quarters knife fighters on Earth. Nobody had yet walked into the room carrying a rifle and a reason not to close the distance. They were about to on a specific date at a specific airirstrip in a machine that had been designed for one purpose and then rejected by the men who ordered it.

February of 1938, Connecticut. The United States Navy opened a design competition for a new carrier fighter. And the requirement sitting at the top of the list was not maneuverability, it was not range, and it was not endurance. It was speed. The chief engineer at the VA company was a man of 44 named Rex Bicil.

He had been born in San Jose in October of 1893 and raised in Cumberland, Washington, a coal settlement in the foothills of the Cascades where his father worked underground. That detail has nothing to do with fighter design. And I am telling you anyway because the man who was about to cancel the Imperial Japanese Navy’s most important assumption grew up in a company town at the bottom of a minehaft and taught himself to draw.

The requirement was brutally simple to state and almost impossible to build. If they want speed, then wrap the smallest airframe you can draw around the most powerful engine anybody has. The most powerful engine anybody had was the Pratt and Whitney Double Wasp. 18 cylinders in two rows headed for 2,000 horsepower.

No airframe had ever been designed from a blank sheet of paper around it. This one would be the first. Bicil put a small team on it, and almost immediately they ran into a problem that had nothing to do with speed and everything to do with physics. 2,000 horsepower is worthless unless you can get it into the air. They ran the propeller arithmetic and came out needing a disc better than 13 ft across.

By the standards of that decade, this was an enormous propeller. And now you have to fit it to an aircraft that lands on a ship. The blade tips have to clear the deck. Long landing gear would give you the clearance. Except that long landing gear on a machine that gets slammed down onto a moving steel deck over and over, month after month, is one of the worst ideas in aviation.

So they bent the wing, not the whole wing, the route. Drop it downward out of the fuselage. Then angle it back up again and put the landing gear at the bottom of that bend. Now the gear can be short and stubby and strong. And the propeller still clears the deck. And there was a bonus that fell out of the drawings for free.

Because the bent route meets the fuselage at a right angle, the interference drag at that junction largely disappears. Nobody drew that wing because it looked good. Nobody drew it for combat. It came out of the arithmetic and everything else was a gift. On the morning of May 29th, 1940, VA’s senior test pilot, Lyman Bullard, lifted the prototype off the runway at Bridgeport.

He was up for about half an hour. The flight went normally until the trim tabs on the elevator began to flutter and then failed, and he brought it home in a hurry. That autumn, the same prototype flew a measured course between two Connecticut cities and averaged better than 405 m an hour over the ground. No American single engine fighter had ever done that.

The army’s frontline fighter of the day topped out somewhere around 360. That number is where most tellings of this story stop. It is where the actual mechanism begins because 405 m an hour is not simply faster. What Bicil’s team had really built was a reserve. Speed and altitude are the same currency. You can spend one to buy the other in either direction all day long.

A fighter with surplus power can convert it into height. Sit up there where the air is thin and the cold gets into your hands. Spend the height to arrive at enormous speed. Then convert that speed straight back into height and be gone before the answer arrives. A surplus like that is not a performance figure on a data sheet. It is an option.

It is the option to be somewhere else. The Zero had sold that option in the 1930s in order to buy the turn. It was the correct trade for the war Japan expected to fight. It was the wrong trade against an opponent who never intended to turn at all. Bicil had banked it instead. And from the day Bullard landed at Bridgeport, an American fighter existed that could refuse. They would call it the Corsair.

So much for the good news. The Navy came back and demanded heavier armament. Six half-in machine guns, three in each folding outer wing panel. Those guns went precisely where the wing fuel tanks lived. So the fuel had to move into the fuselage into a single large tank between the engine and the pilot.

Bicil would not fatten the fuselage to stack the cockpit on top of it because the slim fuselage was the entire speed argument and he was not going to give it back. So the cockpit went backwards instead about 3 ft. And with that the pilot lost the ability to see forward on the approach. The nose and that great bent wing were in the way at the exact moment a man most needs to see where he is going, which is the moment he is trying to put an aircraft down on a ship. Add the rest of it to the list.

A vicious stall in which the left wing dropped without warning. Landing gear whose struts refused to compress properly so the aircraft bounced off the deck high enough that the tail hook could not catch a wire. cowl flap actuators that leaked oil back onto the windscreen at the worst possible time. Naval aviators started calling it the Enson eliminator.

The nickname was not affectionate. It meant the aircraft killed inexperienced pilots. The Navy looked at all of that and made a decision that changed the Pacific Air War by accident. It kept the docsel forgiving Hellcat for the carriers and it handed the fast evilteered Corsair to the Marine Corps for land bases which is how 12 Corsairs of Marine Fighting Squadron 124 came to be parked in the mud on Guadal Canal in February of 1943.

Their first mission was quiet. A handful of Japanese fighters came out, had a look at the newcomers from a distance, and declined to come in. Two days later, the Japanese came. Nine Liberator bombers, 10 Lightnings, and 12 Corsaires went out against shipping off southern Bugganville. Something close to 420 zeros intercepted them.

Nine American aircraft went into the sea. The American pilots and the bomber gunners between them claimed 14 Japanese aircraft destroyed. Postwar examination of the Japanese unit records shows the actual loss for the day. One, and the man in it, a flight petty officer of the 252nd Air Group named Yoshio Yoshida, was not shot down at all.

In the middle of the melee, he collided with the Corsair flown by Lieutenant Gordon Lion, and the two of them went into the water together, 9 to one. The surviving Japanese pilots of that unit fired more than 5,000 rounds of machine gun ammunition and better than 1300 rounds of cannon in the course of it which tells you exactly how long that fight lasted and exactly how close it was.

Somebody in the Solomons called it the St. Valentine’s Day Massacre and the name stuck because it fit. If you want to know what that felt like from inside an American cockpit, it felt like being in a room with the doors locked. The bombers grinding along below at their fixed speed and their fixed heading, the sea flat and hard and gray underneath, and the zeros coming through the formation again and again from angles a man could not cover.

Tracer going past the canopy in long lazy arcs that only look lazy until one of them arrives. The smell of cordite pulling back through the cockpit every time the guns went off. Somebody calling a warning that half the flight could not hear. And underneath all of it, the knowledge that there was nowhere to go because going anywhere meant leaving nine bombers full of men to finish the morning by themselves.

So on the first day that Corsaires and Japanese veterans met each other, Japan’s pilots imposed close combat completely. Totally. They got every single thing they had spent 15 years training for. And here is how they did it. They did it by exploiting the one condition on Earth that cancels a speed reserve, an escort obligation.

The Americans were tied to the bombers. Tied to the bombers means low. Low means slow. Slow means holding station. It means you cannot spend altitude because you do not have any to spend. And it means you cannot leave because the men in those bombers cannot leave either. And you did not come out here to watch them die alone.

Think about what that means. The reserve had existed inside that airframe since the spring of 1940. 2,000 horsepower, 405 m an hour. All of it sitting right there in the wreckage on the day of the massacre. It bought them nothing because nobody had yet written down how to spend it. Gordon Lion’s name appears in the record for exactly one reason.

Because a Japanese fighter found him in a fight his squadron should never have accepted. Most of the men in this story never became famous, and the ones who died on the bad days almost never do. The instructions for how to spend that reserve already existed. They had been written eight months earlier in a pete bog on an island in the Illutions by a 19-year-old Japanese petty officer who never intended to write anything at all.

June 4th, 1942. Akutan Island in the fog and the cold, 4,000 m from the Solomons. Flight Petty Officer Firstclass Tatayoshi Koga was 19 years old. He had launched off the carrier Ryujo that morning and gone in against the American base at Dutch Harbor and coming off the target a single rifle caliber round from the ground had cut the oil return line on his zero.

Oil was streaming back over the fuselage in a black smear. The engine was going to seize. It was only a question of when. Japanese naval aviators operating in that theater had standing instructions for exactly this situation. Find the designated emergency island. Put the aircraft down. Wait for a submarine. Koga turned for a couton with two comrades flying escort above and behind him.

Everything about that stretch of ocean is hostile to a man in a single engine aeroplane. The illusions sit under a permanent gray lid. The cloud comes down to meet the water and the horizon disappears and the cold works its way through the flying suit and into the joints of the hands until the throttle feels like something belonging to somebody else.

Below him there was nothing but slate colored swell and water that cold does not give a man very long at all. He would have been listening to his engine the way you listen for a sound in a house at night, waiting for the note to change, knowing that when it changed, there would be no second chance to pick a spot.

Then the island came up out of the mirc, and he picked out a broad, flat expanse of green. It looked like a meadow. And here is the detail that hurts. One of his wingmen, a petty officer named Sugu Shicata, looking down at that same green from a few hundred feet up, believed there was solid ground underneath the grass.

And he told Koga so there was no solid ground at all. It was a bog under about 2 ft of standing water, and the grass was growing straight up out of it. Koga did what a man does when he believes he is landing on a field. He put the wheels down. The main gear dug in and stopped dead. The aircraft snapped over onto its back and the impact broke his neck. He was 19.

He did everything correctly. He followed the standing orders. He trusted his wingman and it killed him. 5 weeks later, an American patrol plane went over that spot and somebody in the crew looked down and saw a shape in the grass with a red circle painted on it. A party went in on foot.

What they found lying upside down in the mud was the single thing every intelligence organization in the Allied world had been asking for since the first week of the war. A zero that was essentially intact. They got it out with enormous difficulty. Barged it, shipped it, and delivered it to a naval air station in San Diego. Mechanics rebuilt the tail surfaces, the wing tips, the flaps, the canopy, and the landing gear.

They straightened the propeller, painted the whole thing in American colors, put stars on it, and posted armed guards around it. In the autumn of 1942, Lieutenant Commander Eddie Sanders took it into the air. Over the following weeks, he flew it 24 times. And in his report, he wrote down three things. one. Above about 200 knots, the Zero’s ailerons went solid.

Not stiff, solid. Rolling the aircraft at those speeds became a slow, heavy, two-handed job that a man had to fight for. Two, it rolled far more easily to the left than it did to the right. There was a preferred direction. It was not symmetrical, and therefore it was predictable. Three, the engine used a float type carburetor.

pushed the nose over hard into negative acceleration and the fuel supply came away from the pickup and the engine quit. Now hold those three findings up next to each other and watch what happens. If a zero is on your tail and you cannot outturn him and you cannot outclimb him, then put the nose straight down hard using negative acceleration if you can stand it. His engine stops.

Yours keeps running. That opens the range. Then, as your speed comes up through 200 knots, roll hard to the right into the direction his ailerons hate before he can get his sight back onto you. There it is. The entire prescription, three sentences, no equipment required, executable by a frightened 20-year-old with sweat running into his eyes.

That is the moment the surplus horsepower stopped being a specification and turned into a procedure. Because here is the thing nobody had yet said out loud. Every other form of combat in that war could be forced onto a man who wanted no part of it. Artillery finds you in your hole whether you consent or not. A torpedo finds a ship that would very much rather be somewhere else.

But a turning fight is a transaction, and a transaction requires two parties. From that autumn onward, the Americans held the only thing that lets a man walk out of a transaction, which is the physical ability to leave. And now, in writing, they had the instructions for how. There was one American who had gotten there first, without a captured aircraft, and without ever having seen a zero in his life.

In 1941, a lieutenant commander named John Thatch read an intelligence bulletin describing the extraordinary climb and turn of a new Japanese fighter. Nobody in the United States Navy had yet fought one. Thatch took it seriously. Anyway, he sat down at the kitchen table of his rented house in Coronado, California, took out a box of kitchen matches, and let each match stand for an aeroplane.

He worked at it at night, moving matchsticks around on the tablecloth until he had a formation that would let two slower aircraft cover each other against one faster and more agile one. He proved it himself at midway. A man solved the problem with matchsticks before he had ever laid eyes on the thing he was solving for.

But a bulletin is a piece of paper, and what you actually need is a reflex, which brings in a former enlisted pilot from Brooklyn. Kenneth Walsh had come up the hard way through the ranks, flying as a sergeant before he ever flew as an officer. By 1943, he was in his seventh consecutive year of frontline flying, an almost unheard of run.

When his squadron got Corsa’s Walsh went looking for advice, he found an experienced Wildcat pilot who had made a name for himself in the worst days over Guadal Canal and asked him how you fight a Zero. The man told him, “You have to go after them.” That was the whole answer. That was the accumulated doctrine of a year of war delivered in six words.

So Walsh built the rest of it himself, and the sentence he eventually arrived at is the cleanest statement of this entire mechanism that anyone on either side of the war ever produced. “Whoever had altitude,” he said, dictated the terms of the battle. and he added flatly that there was nothing the man in the zero could do about it. Not had an advantage, dictated the terms.

Walsh had worked out the arithmetic underneath it, too, and it explains why one pass was enough. Six half-in guns, each with several hundred rounds firing at something like 800 rounds a minute a piece, sighted to converge a few hundred yards ahead of the nose. A burst of two seconds puts a wall of metal into the air.

On the receiving end was a fighter with no armor plate behind the pilot and no self-sealing tanks anywhere in it. You did not need to stay. You needed two seconds. In May of 1943, near the Russell Islands, Walsh shot down three zeros in a single action and became the first man to make ace flying a Corsair. But I promised you an honest account, and an honest account has to include the days when it did not work.

August 30th, 1943, Walsh took off to escort liberators against Bugenville, and his engine started running rough. He put down at Munda, climbed out, took a different Corsair off the line, and went back up alone to catch his flight. He caught up with them over Cahili. He also caught up with something in the region of 50. No altitude left to spend, no wingman, no way out.

The transaction he had spent a year refusing was now the only transaction available. There is a particular kind of silence that arrives in a cockpit at a moment like that. Not the absence of noise. There is plenty of noise. The engine at full military power, the airframe complaining, the guns of somebody else’s airplane knocking pieces off the sky nearby.

It is the silence of the arithmetic finishing itself. A man in his seventh year of frontline flying looks left, looks right, checks his fuel, counts what is above him, and understands with complete clarity that the doctrine he spent a year building is not available today. He is going to have to do the thing he told every young pilot in his squadron never to do.

And he is going to have to do it alone. And he is going to have to do it now. He got four of them. Then the cannon shells found him. The engine quit and he put the aircraft into the water off Vela Lavella in a dead stick landing watched by American construction troops on the beach who came out and pulled him from the sea. He received the Medal of Honor for that day and for another one two weeks before it.

The ledger on Kenneth Walsh reads like this. 21 victories shot down three times. That is what this mechanism looks like from the inside. It is not invulnerability. It never was. When the reserve was gone, when a man was alone and low and out of speed and out of company, Japan’s veterans imposed close combat on him exactly as advertised.

And it cost him his aircraft and very nearly his life. The whole game from 1943 onward was never about winning the grapple. It was about never being handed one. By January of 1944, you could read the result in the Japanese ledger instead of the American one. Air groups at Rabbal were being pulled out, flown north, or simply ground away.

One unit that had been among the most formidable fighter organizations in the Pacific reached a point where it could put a single serviceable aircraft into the air. One. This was not one-sided, and nobody should pretend it was. On the 3rd of January, Major Gregory Boington, the best known Corsair pilot in the Marine Corps, was shot down over Rabbal and spent the rest of the war in a prison camp.

Men died in both directions every week. But the ledger only ran one way, and the Japanese knew it better than anybody. The question was what to do about it. And what they did about it produced the strangest single piece of engineering to come out of the Japanese aircraft industry in the entire war. A device with exactly one job to force the fight the Americans kept refusing.

On a quiet afternoon in the spring of 2005 in a conference room in Kamakura, a man in his 80s stood up to give a lecture. He had been a school teacher for most of his life. He was offered a chair and he declined it. and he stood and talked for more than two hours. His name was Toshio Hijikata and 60 years earlier he had flown Zeros in combat.

What he came to talk about was not heroism and it was not tragedy. It was training. You have to understand what the syllabus had become by the time men like him went through it. Hiner Comey was not one tool among several. It was the tool. It was the thing they were drilled in over and over against other pilots being drilled in the same thing for as long as the fuel held out.

And by his account, they never once flew practice combat against a different type of aircraft, which meant they had no way of knowing how their machine actually compared to whatever was going to come down at them until the day it came down at them for real. Now, look at the maneuver itself with the eyes of 1945 instead of the eyes of 1934.

Executing that twist at the top of a loop brings the aircraft almost to a stop in the air. That is not a flaw in it. That is how it works. The whole point is to trade away speed in order to buy an angle nobody else can reach. In 1934 over Tokyo Bay with one man behind you and nobody else in the sky, that trade bought you a firing position.

In 1945, it bought you three seconds as a stationary target, and there was always somebody else in the sky. The one thing a pilot could not afford to give away by that stage of the war was airspeed. And the national maneuver was built entirely out of giving away airspeed. There is an older comparison that fits this, and it comes from Japanese history rather than from any American telling of it.

In the 13th century, when the Mongol fleets came ashore in northern Kyushu, Japanese warriors rode out onto the beach in the manner they had always fought. They announced themselves. They stated their lineage. They called for a single opponent of matching rank and offered a duel. The Mongols shot them down in volleys. Neither side was braver.

One side had simply arrived with a different idea of what a fight was and had no intention of being talked out of it. So what did Japan do about it? Not a new maneuver. Something far more interesting than that. The Kawanishi Shiden Kai first flew at the very beginning of 1944. Four cannon self-sealing fuel tanks, armor for the pilot, all the things the Zero had deliberately gone without.

It could meet an American fighter on level terms in a way no Japanese naval fighter had managed in 2 years. and bolted inside. It was a device that no other combat aircraft on Earth carried. The landing flaps doubled as combat flaps, and they were driven automatically, not by the pilot, by a sealed tube of mercury plumbed into the aircraft’s air pressure system.

The mercury moved with acceleration and with air speed. When the pilot hauled into a hard turn, the tube sensed it and put the flaps out as much as 30 degrees, adding lift, dropping the stall speed, tightening the turn. When he rolled out, it took them back in again. He never touched a lever. He never had to think about it.

Sit with what that object actually is. Somebody in Japan looked at what was happening in the sky, understood that everything in the world came down to who won the instant of the turn, and built a machine to win that instant automatically so that the pilot could spend his entire attention on staying alive.

Nobody else in the war built anything like it. It is genuinely brilliant. And then Japan did the other half. On Christmas Day of 1944, a new air group was formed. And in January, it was handed to Captain Minoru Genda, the same officer who had stood at Yakoska a decade before the war and watched Isamu Mochisuki twist out of the top of a loop, the man who had helped write that maneuver into the syllabus in the first place.

Genda went and got the survivors. While much of the Navy was pouring its remaining young men into suicide units, he assembled a fighter group out of the best aviators Japan had left under squadron commanders who had been flying combat since the beginning. He got his own dedicated reconnaissance aircraft fast enough to survive so that for the first time in two years, a Japanese fighter unit would see the Americans coming instead of being caught on the ground. So here it is.

Everything on the table at once. The best pilots Japan had left. The best fighter Japan ever fielded. A device whose only reason for existing was to win the close turn. An early warning so they could arrive with the height. If the men in the Corsaires could still refuse a fight under those terms, they could refuse anything.

March 19th, 1945, more than 300 American aircraft came in against the naval base at Kuray and the airfields around it. Very nearly the number Japan had sent to Pearl Harbor, arriving now in the opposite direction. Genda put up everything he had. 21 fighters from one squadron, 17 from another, 16 from a third. Warned in advance at altitude over their own country.

When they landed, they counted 52 American aircraft shot down. Decades later, researchers matched the action reports of all 27 American squadrons that flew that day against the Japanese unit records. The Americans had lost 14 fighters. The air group had lost 15 of its own aircraft and 13 pilots along with a reconnaissance machine and its three-man crew.

and nine more Japanese fighters went down in the same fighting. Be fair about that because fairness is the whole point of telling it properly. It was the best day any Japanese fighter unit had in 1945 and overclaiming on that scale was completely normal on both sides for exactly the reason it had been normal over Chongqing 5 years earlier.

The Americans claimed 63 the same day. Nobody was lying. But do not look at the score. Look at the shape of the day. A defensive interception over their own airfields with warning against an enemy who had come to them. The most favorable conditions Japan would ever assemble in the entire war, and they still could not turn it into the fight they wanted.

Then 10 weeks later, they did. On the 2nd of June 1945 over Kagashima Bay, Genda’s pilots caught a squadron of Corsaires from an American carrier down low, hunting targets on the ground, slow and looking downward. The Japanese came out of the height with complete surprise, and by the end of it, the American squadron had been badly beaten.

It was an unambiguous defeat, and it belongs in this story. But ask the question, this whole thing exists to answer. On the day Japan’s best finally imposed combat on Corsaires and won it decisively, what kind of combat did they impose? They came from above with surplus altitude and surprise. They dived. They fired. They used their energy to control the engagement from the first second to the last. That is not kakutosen.

That is ichigeki ridatu. The exact tactic that stands opposite the grapple in their own language. The thing the Americans had been doing to them since 1943, the thing their own pre-war doctrine had taught them was the recourse of pilots who could not fight properly. Japan’s finest aviators in the finest aircraft their industry ever produced, fitted with a tube of mercury, whose sole function in the world was to win a turning fight, beat a Corsair squadron badly by declining to turn.

The rest of the story is arithmetic of a different kind. The Sheden Kai’s engine had been designed around high-grade aviation fuel. By 1945, the fleet was running on something considerably worse, sometimes cut with a distillate pressed out of pine roots. An engine rated near 2,000 horsepower was delivering a great deal less than that when it ran at all.

On any given morning, a large fraction of the group’s aircraft turned back before reaching anything with mechanical failures. The pilots ran out, too. By the summer, Japan’s elite fighter group was taking replacements from the bottom of the training pool. On the 1st of August 1945, Lieutenant Naoshi Kano, 23 years old and one of the best fighter leaders left in the country, took off to intercept American bombers.

The barrel of his own gun burst. Damaged, he was shot down by the escorting fighters off the island of Yakushima, and he was never found. In the last weeks of that August, three Shiden Kai were flown from Matsuyama up to Yakosa so the Americans could examine them. Japanese pilots flew them. Their escort was four United States Navy Corsaires.

Now, the verdict, and it means killing two legends. The first is the number that gets quoted in every documentary. Better than 2,000 Japanese aircraft shot down by Corsaires against fewer than 200 lost to enemy fighters, 11 to1. The researcher, Michael Claringbold, did the work nobody had done. He went through the Japanese unit records and matched them loss by loss against the American claims.

The celebrated ratio does not survive contact with the Japanese paperwork. The margin was real. It was nothing remotely like 11 to1. The second legend is the nickname whistling death supposedly bestowed by terrified Japanese pilots. There is no solid Japanese source behind it.

Marine Corps histories that repeat it hedge with the word allegedly. It reads exactly like something an American press officer wrote because it probably is. which is a pity because what those men actually left behind is better than any nickname. They left their own pilot’s verdict on their own doctrine delivered 60 years later by a school teacher in a room in Kamakura who would not sit down.

So the answer is not that the Americans had an aircraft 11 times better. They did not. Japan’s best pilots never lost the close fight against the Corsair. They were never granted one because the grapple is the only form of combat in the world that requires the other man’s consent. And a coal miner’s son at a drawing board in Connecticut had designed that consent out of the war before the war began.

There is one more date and it is the one that closes the circle. Isamu Mochisuki, the man who built Hineri Comey over Tokyo Bay, was killed on the 6th of February 1944. 13 days later, north of Rabbal, four of his countrymen boxed in a lone American fighter at wavetop height and could not make him fight.

Keepford had run out of options. He could not outfly them down there, and he could not outrun them for long enough, so he did the only thing left. He cut hard to the left and reversed his heading straight back south over the water. The pilot on his left hauled in to cut the corner and misjudged how little air there was underneath him.

A wing tip went into the sea. The aircraft cartwheelled and came apart. The ones on his right had been thrown too wide by the reversal to recover the angle. They let him go. He landed with the fuel gauges near the pins. That fight took place on the last day of the air war over Rabal. Within a day, every surviving Japanese aircraft on the island was flown out and never came back.

The men who chased Keepford and could not close were among the last ones to try. He went home the following month with 16 victories in 76 days of combat flying. The leading ace of the United States Navy, he never flew another combat mission. Then he did the most ordinary thing imaginable. He took a job as a trainee in a drugstore, worked his way up from behind the counter, and retired as president of the company.

He died in Michigan in January of 1987, aged 67. If you had met him buying a newspaper, you would never have known. So remember what the argument was actually about. Not who was braver, not who flew better. The men in those zeros flew beautifully to the very end, and the best of them died, still flying beautifully.

It was about who got to decide when the fighting started and when it stopped. That is the quietest advantage there is. And it was one at a drawing board in Connecticut, in a bog in Alaska, and in the cockpits of young men with the discipline to keep climbing when every instinct they owned was screaming at them to turn and Right.
