If you grew up watching the newsreels from the European theater, you remember the narrator praising the Norden bombsight. We were told that American technology could drop a bomb into a pickle barrel from 20,000ft. It was a comforting idea, a clean mathematical war where superior engineering kept our boys safe in the clouds.

 But by the summer of 1942, in the humidity of the Southwest Pacific, that comfortable myth had completely unraveled. The reality on the ground, or rather in the air over New Guinea, was that the Fifth Air Force was bleeding to death. We weren’t fighting stationary factories in Germany.

 We were fighting moving ships in the open ocean and trying to hit a zigzagging destroyer from high altitude. Wasn’t precision bombing. It was a lottery. The casualty reports landing on General Kenney’s desk were grim. In July alone, the Third Attack Group had taken heavy losses. Crews gone. And for what? They had almost nothing to show for it. When the bombardiers stayed high, they missed the Japanese captain simply watch the bay doors open, waited for the drop and turned the wheel.

So the pilots tried the only other option. They dropped altitude. They came in low to ensure a hit. But the moment they dropped below the clouds, they weren’t hunters anymore. They were targets. The Japanese deck gunners, seasoned and disciplined, shredded the unarmored bombers before they could even line up a run.

 Captain Ed Larner, a man who had seen enough combat to know the odds, had watched his own crews burn into the Coral Sea. The Japanese navy was reinforcing New Guinea at will. And we didn’t have a tool in the shed capable of stopping them. This is where the history books usually introduce a general or a politician. But the solution didn’t come from Washington.

It came from a 43-year-old man crouching under the wing of an A-20 at Eagle Farm airfield in Brisbane. His name was Captain Paul Gunn, but he wasn’t your typical army officer. He was a former Navy chief petty officer and enlisted pilot who had spent 20 years turning wrenches and flying planes the hard way.

He approached the war not with the white gloves of an officer, but with the dirty hands of a master mechanic. And he had a motivation that went far beyond patriotism. His wife and four children were currently trapped in the Santo Tomas prison camp in Manila. Every Japanese ship that reached New Guinea extended the war, and every day the war extended was another day.

His family might not survive. Gunn looked at the problem like the mechanic he was. He teamed up with Major Bill Benn, General Kenney’s aide, who had been experimenting with a radical new tactic called skip bombing. Benn figured out the physics of skipping a bomb like a stone, but he was testing it in heavy B-17s that were too slow for the job.

Gunn realized that for Benn’s tactic to work in daylight, the bomber needed to become something else entirely. Imagine skipping a stone across a pond. Now imagine that stone is a 500-pound bomb, and the pond is the hull of a Japanese transport ship.

 If a bomber could fly low enough literally at mast height, they could skip the bomb right into the side of the ship. It would be impossible to miss, but there was a massive structural flaw in this plan to skip a bomb. You have to fly straight and level right into the teeth of the enemy’s anti-aircraft fire. You are serving yourself up on a platter. Before we see how Gunn solved this, I’m curious.

Where are you folks watching from today? Drop a quick comment below. It helps connect our community. Gunn realized the bomber needed to become something else entirely. It couldn’t just be a delivery truck for explosives. It had to be a suppression weapon. It needed to unleash a wall of lead so dense that the Japanese gunners on the deck would be dead or hiding, before the bomber even released its payload. The problem was, the A-20 Havoc wasn’t built for that.

It had a glass nose for a bombardier and light machine guns mounted inside blisters against infantry. 30 cal is fine, but against the hardened steel of a naval destroyer, those rounds bounced off the ship armor like hail. Gunn didn’t need a peashooter. He needed a sledgehammer.

 He needed 50 caliber guns, four of them mounted right where the bombardier usually sat. Firing over 3000 rounds per minute combined. He was proposing to turn a medium bomber into a flying heavy machine gun nest. The engineers said it would throw off the center of gravity. They said the recoil would tear the nose off. But Gunn wasn’t listening to the engineers. He was listening to the clock ticking for his family in Manila.

He stripped guns from wrecked fighters, welded a steel frame into the nose of a bomber and prepared to test a plane that everyone said shouldn’t fly. To understand why Captain Paul Gunn was crouching under a wing in Brisbane, welding machine guns into airplanes with his own hands, you have to look beyond military strategy for most men in the Fifth Air Force.

The war was a job, a dangerous, necessary job to protect their country. But for Pappy Gunn, this wasn’t geopolitics. It was a rescue mission. While Gunn was in Australia arguing with generals, his wife Polly, and their four children were trapped behind the barbed wire of the Santo Tomas Internment Camp in Manila.

They had been there since January 1942. Imagine the psychological weight of that. It is like trying to repair a watch while someone is holding a hammer over it. Gunn wasn’t just fighting the Japanese navy, he was fighting the clock. The intelligence reports coming out of Manila were not just strategic data points to him. They were terrifying personal updates.

The conditions in Santo Tomas were medieval. We aren’t talking about mere discomfort. We are talking about slow erasure. The food rations were being cut to starvation levels. Medicine was non-existent. The transcript paints a grim picture of the physical toll this took.

 By the time the liberation eventually came, Gunn’s wife, a grown woman, would weigh only 89 pounds. His daughter Julia would wither away to 63 pounds. They were surviving on watery vegetable soup and a scoop of rice once a day. Every calorie they didn’t get was a calorie that fueled Gunn’s obsession. But the Japanese camp commander had added a final, chilling layer of horror.

He had informed the Red Cross that if Allied forces ever approached Manila, the prisoners wouldn’t be liberated. They would be executed. Gunn knew he couldn’t just wait for the army to march in slowly. A long war of attrition meant his family died. He had to break the Japanese supply lines.

 Now he had to starve the enemy out before the enemy starved his children out. This desperation drove him to push past the limits that would have grounded any other man. The transcript reveals a moment later in the war on November 27th, 1944. That perfectly illustrates this mindset. Japanese bombers hit the Tacloban airfield while Gunn was in a tent nearby, reviewing mission plans. The blast wave knocked him flat.

 Shrapnel tore through the canvas walls, embedding itself in his arm and leg. Now consider the context. He was 45 years old. He had served 26 years between the Navy and the Army. By all rights, he had earned his ticket home. But when the medical officer found him, Gunn was trying to stand up, blood soaking through his flight suit, demanding to go check on his aircraft.

The surgeon told him the hard truth. You won’t fly for six months, maybe longer, in the military. That is a medical retirement ticket for a normal officer. That is a relief for Gunn. It was a death sentence for his family. He looked at surgeon in the eye and refused to be evacuated.

 He said he wasn’t going anywhere until his family was free. Pain was irrelevant. Biology was just a suggestion. This context is critical because it explains why he bypassed the standard bureaucracy. But he wasn’t working entirely in the dark. He grabbed Jack Fox, a factory rep from North American Aviation who was in theater.

 Fox provided the structural sanity check, ensuring the nose wouldn’t snap off while Gunn provided the sheer force of will. When a man in Ohio tells you that adding four machine guns is impossible, you usually listen unless you know your son is shaking with malaria and your daughter has dysentery. He tested the planes by flying them himself. If the plane killed him, so be it.

 But if it flew, it could kill the ships keeping the Japanese war machine alive. We have to jump ahead for a moment to understand the full cost of this drive. When Gunn finally reached Manila on February 4th, 1945, he went straight to the makeshift hospital. He was walking with a cane, his legs still bandaged from the shrapnel. The reunion wasn’t the movie star moment you might expect. It was a tragedy of attrition.

Polly didn’t even recognize him. He had lost 40 pounds since she last saw him. His hair had turned completely gray from the stress. She actually thought he was a doctor coming to check her chart. It wasn’t until he said her name that the recognition flickered in her eyes. That moment, that recognition was the fuel that built the B-25 gunship.

The sheer violence of the Commerce Destroyer wasn’t born out of hatred for the enemy, but out of a desperate, terrifying love for a family that was fading away. When the experts said it can’t be done, Gunn didn’t hear technical advice. He heard an obstacle and he had a blowtorch to remove it.

 General George Kenney gave Gunn exactly one week to prove his concept wasn’t a suicide pact. But there was a catch. A massive logistical hole that would have stopped a modern project manager cold. Gunn didn’t have the parts. He wasn’t working in a sanitized hangar at Boeing or Douglas with a supply chain of fresh components.

 He was at an airfield near Brisbane, thousands of miles from the factory, with a supply closet that was effectively empty. So Gunn had to stop being an officer and start being a scavenger. He went to the Boneyard, the graveyard of wrecked aircraft on the edge of the airfield. He found the carcasses of P-39 and P-40 fighters that had been shot up in previous engagements. The transcript delivers a line here that chills the blood.

The pilots were dead. The guns weren’t Gunn ordered mechanics to strip the 50 caliber machine guns out of these twisted wrecks. He was building a Frankenstein monster, crafting the offensive power of dead fighters onto the chassis of a living bomber. His first patient was the A-20 Havoc. It was a light bomber, fast and nimble. But it was designed to drop bombs, not dogfight.

Gunn’s plan was to rip out the bombardier seat, remove the glass nose where the aiming happened, and replace it with a metal sheet holding four of those scavenged 50 caliber guns. But physics is a cruel mistress. You can’t just bolt heavy machinery onto the front of an airplane and expect it to fly straight. Each of those 50 caliber guns weighed 64 pounds.

That’s 256 pounds of steel alone. Add the mounting frame, the feed chutes and 200 pounds of ammunition, and you suddenly hung a quarter ton of dead weight on the very tip of the airplane’s nose. Any pilot listening to this knows exactly what happens next. The center of gravity shifted violently forward when the test pilot took the modified A-20 up. The aircraft tried to kill him.

It refused to climb. It wanted to nose over and dive straight into the Australian dirt. So Gunn spent two sleepless days acting as a physiological engineer for the airplane. He couldn’t remove the gun, so he had to move everything else. He tore out radio equipment from the cockpit and moved it to the tail.

 He adjusted the trim tabs to their absolute limit. He was balancing a seesaw that was never meant to be balanced. The second test pilot reported that the plane flew like it was angry, but it flew. In September, they proved the concept. 16 of these angry A-20s hit the Japanese airfield at Buna. They came in at treetop level.

 The Japanese ground crews, expecting high altitude bombers, were caught completely exposed. The A-20s destroyed aircraft on the ground and suppressed every anti-aircraft position. It was a triumph, but in war, a solution to one problem often reveals a second, deeper problem. The A-20 was a sprinter. It didn’t have the legs for a marathon.

 The Japanese bases were on the other side of the Owen Stanley Mountains, a jagged spine of rock that divided New Guinea. The A-20s simply didn’t have the range to cross the mountains, fight and return. They were short range brawlers in a long range war. That’s why Gunn looked across the tarmac at the B-25 Mitchell. The B-25 was a medium bomber.

It had the range. It had the payload, but it was a lumbering beast compared to the A-20. The engineers back in the States designed it to fly straight and level at 10,000ft. Dropping bombs on factories. Gunn looked at it and saw a gunship. In December 1942, he pulled a B-25 C into the hangar and went to work. If the A-20 was a modification, the B-25 was a total metamorphosis.

He didn’t just fill the nose, he covered the plane in barrels. He installed 4 50 caliber guns in the solid nose, but that wasn’t enough. He cut holes in the fuselage skin on both sides of the cockpit and mounted cheek packs blisters holding two more guns each. Then he rotated the top turret mechanism so the guns locked forward. Do the math with me.

Four in the nose, four in the cheeks, two in the turret. That is ten forward firing 50 caliber machine guns. Later on newer models, he would add two more, bringing the total to 12 or 14 guns depending on the configuration. The ground crews looked at this monstrosity, bristling with barrels like a porcupine, and they gave it a nickname, Pappy’s Folly. They thought the old man had finally lost his mind.

They bet money that the recoil alone would stop the plane in mid-air. When Gunn flew the prototype to Charters Towers to demonstrate it, the nose heavy characteristics were terrifying. On takeoff, the B-25 tried to drop out of the sky. Gunn had to haul back on the stick with full back pressure, just to keep it from plowing into the runway.

 It was a wrestling match with gravity every time the wheels left the ground. But once it was airborne, it was a flying destroyer. Gunn demonstrated the firepower, unleashing a burst. The transcript notes that the plane put out an unbelievable volume of fire. Think about that. That isn’t strafing. That is an industrial demolition. General Kenney watched the demonstration.

He saw the tracers tearing up the target range. He didn’t see a folly. He saw the answer to the Japanese convoys. He ordered 12 more conversions immediately. The 81st Air Depot Group in Townsville went to 18 hour shifts, welding around the clock to build a fleet of these impossible planes. They were ugly. They were nose heavy, and they were built with scavenged parts and scrap metal.

But they were about to change the physics of the Pacific War. Pappy Gunn had built his hammer. Now he just needed a nail. There is an old saying in the military. The map is not the terrain. In early 1943, we saw the ultimate collision between the map represented by the best aeronautical engineers in the United States and the terrain represented by a desperate mechanic with a welding torch in the humid jungle of Australia.

While Pappy Gunn’s Folly was busy tearing up Japanese airfields. General Kenney decided it was time to make the modification official. He didn’t want to rely on scavenging wrecked fighters forever. He wanted the factories back home to build these strafers from scratch. So he sent the blueprints, Gunn’s hand-drawn sketches, and field notes to the Army Air Force engineering hub at Wright Field in Ohio. Now, you have to appreciate the position these engineers were in.

They were the guardians of safety and aerodynamics. Their job was to ensure American pilots didn’t die in preventable accidents. When they unrolled Gunn’s drawings, they didn’t see a weapon. They saw a disaster. They studied the modifications for three days. They ran the math.

 They looked at the weight distribution, adding nearly 1,000 pounds of guns and ammo to the extreme nose of the aircraft. They looked at the structural integrity of the fuselage, which was designed to hold air, not withstand the recoil of a dozen heavy machine guns firing simultaneously. Their conclusion was mathematically sound and completely wrong. They sent a frantic message back to Australia.

The language was absolute. They said the modifications were impractical. The balance was dangerous. The airplane would be too nose heavy to recover from a dive. The recommendation ground every modified B-25 immediately in a normal timeline. That would have been the end of the story. The brass would have folded.

 The planes would have been scrapped, and the B-25 would have remained a medium altitude bomber. But luck, or perhaps destiny, intervened. General Kenney happened to be in Washington, DC when that message arrived. He walked into the office of General Hap Arnold, the supreme commander of the Army Air Forces. The engineers from Wright Field were there waiting.

They were ready to present their findings and explain why this Pappy Gunn character was going to get pilots killed. They laid out their case. The physics didn’t work. The stress loads were too high. Kenney listened politely. Then he dropped the hammer.

 He told them that while they were doing the math, 12 of those impossible airplanes had just played the key role in the battle of the Bismarck Sea. They hadn’t crashed. They hadn’t fallen out of the sky. They had sunk a Japanese convoy. The transcript tells us General Arnold’s reaction was swift. He didn’t ask for a second opinion. He practically ran the engineers out of his office.

 He immediately drafted a message with the subject line Commerce destroyer. Modifications approved for production. The Commerce Destroyer. It has a nice ring to it, doesn’t it? But approving the production was one thing. Actually building it was another. Arnold called J.H. “Dutch” Kindelberger, the president of North American Aviation, the company that built the B-25.

He told him to start building strafers. Kindelberger, being a prudent industrialist, said his engineers needed to see the modifications first. Arnold replied, I’m sending the man who designed them. This brings us to the most reluctant business trip in military history. Paul Gunn was ordered to fly to Long Beach, California.

 To you and me, a trip to California in the middle of a war sounds like a vacation to Gunn. It was a nightmare. Remember, his compass was set to north toward Manila and his starving family. California was east. Every mile he flew toward the United States was a mile away from his wife and children. He argued with Kenny. He pleaded to stay, but Kenny made it a direct order.

Go teach them how to build it. And I promise you’ll be back in six weeks. Gunn landed in Long Beach on March 27th, 1943. The North American Aviation Plant was a behemoth 140 acres, 20,000 workers, three shifts, running 24 hours a day. They were churning out a new B-25 every four hours into this world of precision manufacturing.

Walked Pappy Gunn, a man who measured tolerances with his thumb and tested stress limits by seeing if the wing fell off. The culture clash was immediate. The factory engineers sat Gunn down and asked for his stress calculations. They wanted to see the slide rule work that proved the nose frame could hold the guns. Gunn looked at them and said, I don’t have any.

They asked about wind tunnel testing. They wanted to know the drag coefficients of the external cheek packs. Gunn said, I tested it by flying it. You can imagine the silence in that room to a factory engineer. Testing by flying is insanity. It’s how you kill test pilots. Then came the specific technical objections.

One engineer pointed out that the muzzle blast from the cheek mounted 50 calibers was too close to the fuselage. He argued that the expanding gas and shockwave would peel the aluminum skin right off the airplane like a banana. Gunn didn’t argue the theory. He simply nodded and said it did.

 He explained that on the first few flights, the blast had indeed ripped the skin, so he had welded steel blast tubes to the barrels, extending them just past the propeller arc and away from the skin. Problem solved. This is the difference between an engineer and a mechanic. An engineer tries to design a plane that won’t break.

 A mechanic waits for it to break, then welds a patch over it so it never breaks there again. For two weeks, the factory engineers reverse engineered Gunn’s field modifications. They took his rough hand welded concepts and turned them into production grade blueprints. They strengthened the nose structure with proper trussing. They redesigned the gun mounts to absorb recoil more efficiently.

They added heavier gauge aluminum patches, doubler plates to the side of the fuselage to handle the muzzle blast. Most importantly, they solved the center of gravity issue properly. Instead of just moving radios to the back like Gunn had done, they calculated the exact weight shift and redesigned the tail trim assembly to compensate.

 On May 10th, 1943, the first factory built strafer rolled off the line. And folks. They didn’t just match Gunn’s design, they escalated it. When Gunn arrived, the factory showed him an experiment that was even bigger than his machine guns. The B-25G. They had installed a 75 millimeter M4 cannon in the nose. Gunn hadn’t asked for this. It was a factory idea, but he was willing to fly it. Let’s pause on that.

A 75 millimeter cannon is an artillery piece. It is the main gun of the Sherman tank. It fires a shell the size of a two liter soda bottle, and they mounted it inside an airplane. Gunn test flew the prototype. When he pulled the trigger on that cannon, the weapon recoiled violently. The entire aircraft shuddered, as if it had hit a brick wall in midair.

 The navigator, poor soul, had to manually reload the cannon between shots like he was on a pirate ship. If you appreciate this kind of American engineering history, go ahead and hit that subscribe button. The rate of fire was slow. One round every 30s. Gunn, ever the pragmatist, told the engineers it works for ships. One shell will hole a destroyer below the waterline.

But don’t try to hit anything faster. North American Aviation built 400 of these flying tanks. Then they refined it into the B-25H, which was even deadlier. They added four more 50 cals in the cheek packs, bringing the total forward firing machine guns to 14 plus the cannon.

 They improved the recoil mechanism so the navigator could reload faster. In one round every 20s. Finally, they produced the B-25J. They realized the cannon was a bit of a novelty too slow for strafing runs, so they replaced it with what Gunn had wanted all along. More machine guns. The solid nose J model had 14 forward firing 50 caliber guns, eight in the nose, four in the cheeks, and two in the turret.

 It was the most heavily armed production bomber in history when a squadron of B-25Js opened fire. They were putting over 10,000 rounds per minute into the target. It was a buzz saw, and it all existed because a stubborn man from Arkansas refused to listen to the experts who told him it was impossible.

 Gunn left California in May, exactly six weeks after he arrived, just as Kenney promised he had given the industry the blueprint. Now he was going back to the Pacific to use the weapon. If the impossible gunship was the theory, the battle of the Bismarck Sea was the final exam and the grading curve was brutal. It started with a secret. On February 28th, 1943, Allied codebreakers in Melbourne intercepted a decrypted Japanese naval message that sent a chill through the command center. A massive convoy was leaving Rabaul.

Eight transport ships, eight destroyer escorts, and nearly 7000 hardened Japanese troops were bound for Lae on the north coast of New Guinea. General Kenney had exactly 72 hours to stop them. If those 7000 troops landed. The balance of power in New Guinea would shift and the Allied foothold in the Pacific would crack. But the Japanese commanders weren’t reckless.

They had timed this move perfectly to coincide with the monsoon season. They were betting on the weather. They calculated that low clouds, heavy rain and poor visibility would shield them from American bombers. And initially, they were right on March 2nd. B-17 Flying Fortresses, the heavy hitters attacked from high altitude through breaks in the clouds.

 Usually this was a waste of time, but on this day they got lucky. They managed to sink the transport Kyokusei Maru, carrying over 1000 troops, but seven transports and eight destroyers kept steaming south. Confident that the high level bombers couldn’t stop the main force, they expected to reach Lae by dawn on March 4th, but they had no idea that the rules of engagement had changed overnight.

On the morning of March 3rd, the weather cleared just enough. At 1000 hours, a strike force of aircraft assembled over the convoy. The plan relied on a tactical deception that was pure genius. The B-17s would attack first from high altitude. Their job wasn’t to hit the ships. It was to force the Japanese anti-aircraft gunners to look up.

While the Japanese crews were craning their necks and firing into the clouds, the B-25 strafers dropped down to the deck. Leading the formation was Major Ed Larner. He brought his squadron in from the southeast at wave top height, literally 50ft above the water. Now, I want you to visualize the geometry of this attack because it is unlike anything seen in air warfare before or since.

 Larner didn’t have his pilots fly in a single file line, which allows gunners to pick them off one by one. He ordered them to fly line abreast 12 B-25s spread out horizontally, sweeping forward and a loose wall of destruction to concentrate their fire without crashing into each other. Now let’s do the math on that. 12 aircraft, 10 to 12 forward firing 50 caliber machine guns per aircraft.

 At this stage of the war, that is over 100 heavy machine guns firing simultaneously. When they opened fire, they created a solid wall of lead 300 yards wide and 1000 yards deep. It wasn’t precision shooting, it was a broom sweeping the ocean clean. The B-25s opened fire at 800 yards. The transcript describes the effect as a chainsaw. The 50 caliber rounds didn’t just hit the ships.

They disintegrated the superstructures. The bridges were shredded. The antiaircraft crews were cut down before they could even traverse their guns to the horizon. Then came the skip bombs. The first bombs skipped off the water, slammed into the hulls, and detonated the transport Teiyo Maru tried to run.

 The captain pushed his engines to the red line 15 knots, but the B-25s were closing at 240 knots. The math was simple and unforgiving. Four strafers bracketed the ship from both sides. This is a terrifying tactic known as criss crossing. As the streams of fire converged on the deck, there was nowhere to hide. Then they dropped the bombs. The ship physically broke in half.

The destroyers, the warships designed to protect the transports, fared no better. The destroyer Shirayuki, the flagship, tried to screen the transports, but before the B-25s arrived, Australian Beaufighters strafed it. One Australian pilot, his plane taking fire, kept his run going and raked the destroyer from bow to stern.

By the time the B-25s lined up on the Shirayuki, its defenses were silent. Three strafers attacked from different angles. The destroyer tried to turn, but it was too slow. Bombs hit the port side in the stern. It didn’t sink immediately, but it was finished dead in the water and burning by 0900 hours.

 The convoy was scattered across 40 square miles of ocean. Transports were sinking. Destroyers were crippled. You might think the Americans would regroup and celebrate. They didn’t. They rearmed and came back at 1400 hours. The second wave was absolute extermination. The Japanese Zero fighters, which should have been protecting the fleet, were largely engaged elsewhere or refueling.

The fleet was helpless, while the B-25s returned with fresh bomb loads. The transport Aiyo Maru took the brunt of the second anger. It was hit by multiple bombs. The resulting explosion was so massive it defies description. The ship’s magazine, where the ammunition was stored, detonated.

 The blast was visible from Port Moresby, 130 miles away. When the smoke cleared, there was nothing. No wreckage, no survivors. The transcript states that hundreds of Japanese soldiers were gone in three seconds. Captain Larner then took his squadron low over the Oigawa Maru. His copilot counted 14 separate fires burning on the deck. Japanese soldiers were jumping overboard in a panic.

The anti-aircraft guns were silent. There was no one left alive to man them. Lerner’s bombardier released two bombs at point blank range. Both hit the transports settled by the stern and capsized. Even the rescue operations weren’t spared. The destroyer Asashio was trying to pick up survivors from the water.

When A-20 Havocs attacked, the crew was so focused on pulling men from the sea that they didn’t see the strafers until the guns opened fire. The Asashio burned through the night and sank at dawn. By the evening of March 3rd, the battle of the Bismarck Sea was over. The statistics are staggering. Eight transports, all sunk. Four destroyers sunk.

Of the nearly 7000 troops that left Rabaul. Fewer than 1200 reached Lae. About 2700 were rescued by Japanese submarines. The rest over 3000 men, died in the water. Allied losses four aircraft, 13 aircrew killed. General MacArthur, a man not known for understatement, called it one of the most complete and annihilating combats of all time. The strategic implication was immediate.

The Japanese high command looked at the reports and realized they could no longer send ships to New Guinea. The strafers had effectively cut the island off. From that day forward, Japanese reinforcements had to come by submarine or by barge in the dark, in small numbers. The war in the Southwest Pacific had turned, and it didn’t turn because of a massive naval fleet or a new secret weapon from the Pentagon.

 It turned because a mechanic named Paul Gunn figured out how to bolt machine guns onto the nose of a bomber, and a group of pilots had the courage to fly it right down the throat of the enemy. By late 1944, Paul Gunn was running on fumes. The human body is a machine, and like any machine, if you run it at redline for three years straight without maintenance, eventually a piston is going to blow.

 Gunn had been flying combat missions, designing modifications and fighting the bureaucracy simultaneously since 1942. He was 45 years old. Most men his age were commanding from desks in Brisbane or Washington. Gunn was still in the cockpit, driven by a singular, terrifying purpose. Getting to Manila before the Japanese executed his family.

 But on November 27th, 1944, his luck finally ran out. He was at Tacloban Airfield in the Philippines, reviewing mission plans in the operations tent. It was 0330 hours, dark, humid and quiet. Then the radar operators picked up a flight of Mitsubishi bombers coming in low from the north. They picked them up too late. The first stick of bombs walked right across the airfield.

The operations tent was only 200 yards from the main runway when the blast wave hit. It didn’t just knock Gunn down. It shredded the canvas walls and filled the air with flying metal. A fragment of shrapnel tore into his shoulder. Another piece sliced into his left leg. When the medical officer arrived, he found a scene that defies logic.

Gunn wasn’t lying on the ground, waiting for a stretcher. He was trying to stand up. Blood was soaking through his flight suit, pooling in his boot. But he was arguing that he needed to go check on his aircraft. The surgeon was blunt. The leg wound was catastrophic. He told Gunn he wouldn’t fly again for six months, minimum. In military terms, that is a ticket home.

It meant medical retirement. He had served 26 years. He had earned his pension. He had nine Purple Hearts. No one would have blamed him for going back to the States to recover. But Gunn looked at the surgeon and refused the evacuation order. He said he wasn’t going anywhere until his family was free.

 He spent his recovery in a hospital bed and later, counting the days as the American army inched closer to Manila. The Battle of Manila began on February 3rd, 1945. It wasn’t a tactical maneuver. It was a slaughter. The Japanese had declared the city a fortress and were defending it house by house. But in the chaos, a column of the first Cavalry Division broke through to the Santo Tomas University, which had been converted into an internment camp.

They liberated 3700 Allied prisoners that day. But the condition of those prisoners was a horror story that the history books often gloss over. Gunn’s wife, Polly, and his four children had been surviving on a diet of watery vegetable soup and a single scoop of rice per day for a year.

 When the soldiers opened the gates, Polly Gunn, a grown woman, weighed only 89 pounds. His daughter Julia weighed 63 pounds. His son Nathaniel was shaking with malaria. His youngest daughter was battling dysentery. They were walking skeletons, clinging to life by a thread. So when word reached Leyte that the camp was liberated, Gunn didn’t wait for permission.

 On February 4th, just 24 hours after the gates open, he commandeered a plane. He shouldn’t have been walking, let alone flying. His leg was still heavily bandaged. He had to use a cane to keep upright. The doctors had cleared him for light duty only, which certainly did not include flying into an active combat zone where Japanese snipers were still firing from the rooftops. He landed in Manila and made his way to the makeshift hospital.

The army had set up inside the camp. The reunion that followed is perhaps the most heartbreaking moment of his entire war. You expect a Hollywood ending, the embrace, the tears, the instant recognition. But the war had taken too much from both of them. When Gunn walked into the room, leaning on his cane, Polly looked up and didn’t know who he was.

 He had lost 40 pounds since she last saw him in April 1942. The stress of the impossible gunship and the weight of the command had aged him 20 years in three. She thought he was a doctor coming to check her chart. It wasn’t until he spoke her name, that familiar voice from their life before the nightmare that the realization hit her. The official army report is clinically dry.

It states Colonel Paul I. Gunn was reunited with his family on February 4th, 1945. It doesn’t mention that the reunion lasted only four hours. Gunn couldn’t stay. The war wasn’t over. His medical leave wasn’t technically over either. He had to return to Leyte.

 He had to get back to the business of killing the enemy, so that the transport ships could bring food and medicine to the family he had just found. He walked out of Santo Tomas, climbed back into his plane, and flew back to the war. He had won his personal battle, but the cost was etched into every line of his face. He had saved them, but he had nearly destroyed himself to do it.

 There is a tragic irony that often follows men of war. They survive the impossible. The flak, the Zeros, the shrapnel, only to be taken by the mundane. After the war, Paul Gunn didn’t slow down. He couldn’t. The war had taught him a lesson that had burned into his DNA. Movement meant survival. Standing still meant death. He returned to the Philippines and rebuilt Philippine Airlines from the ground up.

Turning a few surplus C-47s into an international carrier. But on October 11th, 1957, the movement finally stopped. Gunn was flying a Beechcraft Model 18 through the Cordillera mountains north of Manila. It was a routine trip. The forecast called for scattered thunderstorms. Nothing.

 A pilot with his experience hadn’t seen a thousand times. But the weather closed in faster than predicted. The aircraft flew into a storm cell, tried to climb above it, and was driven into a ridge. Pappy Gunn died instantly. He was 57 years old when The Manila Times published his obituary. They listed the medals the Distinguished Flying Cross, the Silver Star, the nine Purple Hearts.

But they missed the real story. They focused on the man. But the true legacy was the method. If you look at the history of air power, there is a clear dividing line. Before Gunn and after Gunn. Before him, bombers were high altitude instruments of strategy. They were designed to drop explosives on factories from the three miles up. After him, the bomber became a tactical brawler.

It became a weapon of close air support that could loiter over a battlefield and deliver pinpoint devastation. So when you look at the Vietnam War and see the AC-130 Spectre gunship circling over the Ho Chi Minh trail, you are looking at the direct descendant of Pappy Gunn’s B-25. The concept is identical.

 Take a transport airframe loaded with an obscene amount of heavy weaponry, far more than the manufacturer ever intended, and use it to suppress the enemy on the ground. The A-10 Warthog that is just a flying gun with wings, a philosophy Gunn proved at the battle of the Bismarck Sea. The numbers alone are staggering. By the end of World War Two, North American aviation had built nearly 5000 strafer variants.

 Those Pacific planes sank hundreds of Japanese ships and destroyed thousands of aircraft on the ground. But the most poignant piece of this legacy isn’t found in a history book or a military museum in Washington. It is found in Fredericksburg, Texas, at the National Museum of the Pacific War. If you go there, you can see a piece of yellowed paper. On it is a pencil sketch.

It has no computer modeling, no stress calculations, and no engineers stamp. It is just a hand-drawn diagram of 4 50 caliber machine guns crammed into the nose of an A-20. It is a humble drawing. But that piece of paper killed 85,000 enemy soldiers and saved the lives of countless Americans. Today, Philippine Airlines still flies to 42 destinations in their headquarters in Manila.

There is a portrait of Paul Gunn in the lobby. Most of the employees walking past it don’t know who he is. They don’t know that the airline exists and that their country is free, because a 43 year old mechanic refused to accept that impossible was a valid excuse when his family’s lives were on the line.

Pappy Gunn was the ultimate scavenger, the ultimate innovator, and the ultimate father. And while the history books might prioritize the generals, the men who flew the strafers knew the truth. They knew who gave them the tools to win the war. And now so do you.
