On 19 July 1966, the Wolfhounds of A Company, 1^st Battalion, 27^th Infantry, were fighting for their lives near Trang Bang, Vietnam. They had air-assaulted into a smoking hot LZ in the Tay Ninh Province and immediately realized they had dropped checks they couldn’t cash. The VC pummeled their positions with B40 rockets along with suffocating AK and SKS rifle fire. The medics were overwhelmed, and they were down to their last few magazines. Fear spread like a contagion.

Amidst the chaos and the panic, the survivors could just make out the distinctive sound of CH47 cargo helicopters. With a little experience, it’s not hard to identify a military helicopter in seconds at a great distance. Apparently some rocket surgeon had foolishly sent a couple of big, fat Chinooks into the middle of a full-bore gunfight. Then the entire world exploded.

Two enormous experimental twin-rotor gunships roared in at treetop level. They opened up with fast-firing 20mm autocannon, screaming 2.75-inch rockets, explosive 40mm automatic grenade launcher rounds, and a veritable hurricane of .50-caliber pain. The attacking VC had just received their rude introduction to Guns-A-Go-Go.

The two A/ACH-47A (later designated ACH-47A) Chinook gunships that broke the back of that VC assault in 1966 were modified versions of the standard CH-47 Chinook. A/ACH-47A stood for Armored/Attack Cargo Helicopter. There’s never been anything like them before or since.

Origin Story

This curious live fire experiment saw four standard A-model CH-47 heavy lift Chinooks converted into gunships. They always worked in pairs and were based at Vung Tau and An Khe. The Army referred to this merry mob as the 53d Aviation Detachment. The earth pigs knew them as Guns-A-Go-Go.

Three aircraft operated in country while a fourth remained behind in the States for further testing at Edwards Air Force Base. The first three were titled “Easy Money,” “Stump Jumper,” and “Birth Control.” The fourth was christened “Co$t of Living.” These massive warplanes absolutely bristled with weapons.

Details

Each ACH-47A carried 3,000 pounds of expendable ordnance along with extra applique armor protecting the crew and vital mechanical components. This spare boron carbide allowed these hulking aircraft to take a beating while operating in close proximity to supported ground troops. Each aircraft carried five fast-firing AN/M3 .50-caliber machineguns, the aircraft version of John Moses Browning’s legendary Ma Deuce.

The AN/M3 was the same weapon used on WW2 fighter planes like the Mustang, Lightning, Thunderbolt, and Corsair. They each cycled at around 1,100 rounds per minute. There were two per side of the A/ACH-47 firing through the windows and a fifth gun fitted in a stinger mount on the aft ramp.

A fixed XM34 M24A1 20mm automatic cannon rode on each side of the aircraft. An evolutionary development of the HS.404 Hispano-Suiza 20mm cannon, each of these recoil-operated guns fired 20x100mm high explosive rounds at 700 rounds per minute. Similar weapons served in deck mounts for antiaircraft defense on Navy warships.

Sponsons built into each side of the aircraft included mounting points for either 19-shot XM159 2.75-inch rocket launchers or M18 7.62x51mm Minigun pods. 2.75-inch FFAR (Folding Fin Aerial Rockets) typically carried either ten or seventeen-pound high explosive warheads. White phosphorus or flechette loads were also on the menu.

The M5 40mm automatic grenade launcher rode in a bulbous chin mount and fired high-velocity 40x53mm HE grenades. These rounds were not interchangeable with the 40x46mm grenades fired by the M79 and M203 launchers. The M5 was an air-cooled, electrically-driven gun system that featured a 225rpm rate of fire and a maximum effective range of 1,870 meters. The gun gimbled and could therefore be fired off-axis from the aircraft. Everyone knew it as the “Chunker.”

Practical Tactical

In August of 1966, “Stump Jumper” was involved in a ground taxi accident with another Chinook and burned. As a result, the Army fetched “Co$t of Living” from California and deployed it to Vietnam as a replacement. The following Spring, one of the M24A1 20mm guns on “Co$t of Living” vibrated loose on its mount during a fire support mission. The big cannon pivoted upward and discharged into the rotor system. High explosive rounds struck the forward rotors and blew them to pieces. All eight crewmembers perished.

A year later, “Birth Control” was badly shot up during a gun run and autorotated into a dry rice paddy near Hue. The crew of “Easy Money” immediately positioned themselves between the disabled gunship and attacking enemy, providing ample cover fire so that the crew of “Birth Control” could extricate themselves.

NVA mortars ultimately found the range and destroyed “Birth Control” before it could be salvaged. With only the single airframe remaining intact, the Guns-A-Go-Go project was no more. AH-1G Cobras rightfully stepped in to fill that role.

Epilogue

After the Vietnam War, “Easy Money” relocated to Fort Eustis in Virginia to be used as a sheet metal trainer. In the late 1990s, “Easy Money” was restored to her wartime configuration. In 2000 she went on permanent display at Redstone Arsenal in Huntsville, Alabama.

The idea of a massive gun truck that could slather hellfire across the countryside for literally hours on end had merit back in 1966. Given the proliferation of shoulder-fired MANPADS (Man-Portable Air Defense Systems) missiles, these enormous testosterone-charged monsters would be easy meat nowadays.

Regardless, “Easy Money” stands in Huntsville, Alabama, today in mute tribute to the era when Army innovators took a cargo helicopter, strapped on as much ordnance as the thing could carry, and then unleashed it on the VC and NVA. As a former Chinook pilot myself, I think Guns-A-Go-Go might just be the sexiest aircraft ever made.

Clyde Childress: WWII Guerrilla in the Philippines

Papers of Colonel Clyde C. Childress, USA

Colonel Clyde C. Childress served as commander of the 107th Division, 10th Military District, during World War II. Serving in the prewar Philippines with the American 31st Infantry Regiment, Childress was chosen to help train the new Philippine Army when it was called into service under Douglas MacArthur’s new United States Army Forces Far East (USAFFE) command in July 1941. Shipped to Panay, where he became a battalion commander in the 61st Philippine Infantry, Childress was there when war erupted with the bombing of Pearl Harbor and Clark Field on December 7-8, 1941.

Though still green and untrained, the 61st infantry was shipped to the southernmost island of the Philippines; Mindanao. Positioned on the south coast of the island, the unit was to guard the air field and coastal region near the town of Malabang. The 61st was quickly overrun with the Japanese invasion of the Cotabato region in April of 1942. Childress was cut off from his command being on the right wing of the defenses when the Japanese routed the 61st. Along with his men Childress retreated by jungle trail to the north coast of Mindanao. During their eight day trek north, the Philippines were surrendered. Childress and his men were now unsurrendered fugitives. Most of his men came from Panay Island and that is where they were headed. Childress, on the other hand, needed to hide.

Physically destroyed by his jungle trek, Childress took refuge with American expatriates on the Zamboanga Coast and recuperated. Like all the Americans that went into the jungle, Childress would not have survived had it not been for the hospitality and complete selflessness of the Filipinos and Americans that helped them. Not all Filipinos, however, were friendly. At one point during his recuperation Childress got word that the local Philippine Constabulary officer was going to come with his men and disarm him. Childress was not one to wait for trouble and instead went looking for it. He showed up at the Filipino’s headquarters. As he approached he noticed the constabulary soldiers smiling at him and knew they were on his side. Childress walked right up to the officer and basically told him to make a move. The officer balked and Childress disarmed him. He would have no trouble from anyone else.

After four months, the “bamboo telegraph” brought word that an American General had arrived in Mindanao by submarine. Childress made the trek by foot along the north coast of Mindanao from Zamboanga to Misamis Occidental. Upon arrival in Jimenez, Childress found the “General.” It was a reserve U.S. Army engineer officer, Lt. Colonel Wendell W. Fertig. Fertig made up the ruse of being a general to gain the support of the local populace and set up his own guerrilla kingdom. Looking like the “wild man from Borneo,” Childress was taken in and cleaned up by the Ozamis sisters of Jimenez, women who risked everything to give support to the guerrillas of Mindanao. Given a shave, bath, and a new uniform, Childress met in conference with Fertig on 20 November 1942.

Much to Childress’s surprise, he was meeting with Fertig and Major Ernest McLish, who had been a fellow battalion commander in the 61st regiment. Childress and McLish had not seen each other since being overrun at Malabang in May 1942. At Jimenez the agreement was made with Fertig that McLish and Childress would go east and organize the eastern areas of Mindanao. McLish, who had already started a guerrilla in the Bukidnon region, was designated as commander of the 110th Division of Fertig’s 10th Military District command on Mindanao with Childress as his Chief of Staff. Fertig felt he could use the two to further his end of being the top guerrilla of not only Mindanao by all the Philippine Islands. He thought Childress the stronger of the two, and would never see eye to eye with McLish. McLish and Childress left by sailboat for the two day trip to Balingasag and the Misamis Oriental region of Mindanao. They wondered “what was the story” with the guy who was calling himself a General.

The 110th Division encompassed a wide area of western Mindanao encompassing the Misamis Oriental, Agusan, Surigao and Davao regions. It was populated with bands of guerrillas all acting on their own initiative and in many cases as bandits. McLish and Childress, with the help of a host of unsurrendered Filipino and American fighters brought order to these areas by supporting legitimate guerrillas and suppressing the bandits. By March 1943, most groups in the Misamis Oriental and Agusan regions were under the control of the 110th Division. The question became, “What do we do now?” It didn’t take long to come up with an idea.

In March 1943, Major Luis Morgan, Chief of Staff of the 10th Military District and the real muscle behind the establishment of Fertig’s guerrilla organization, arrived in the 110th Division area. At odds with Fertig, Morgan had been sent on a tour of Mindanao and the Visayan Islands trying to bring all guerrillas together in purpose. Morgan was a former constabulary officer from the Lanao region of Mindanao. After the American surrender, Moslem bandits began raiding the Christian coastal areas of Lanao. In a brutal campaign of bloodletting, Morgan put a stop to it. He liberated the north coast of Mindanao for Fertig, and was always up for a fight. Going into conference with McLish and Childress, who were just itching for some payback against the Japanese, they came up with a plan to attack the Japanese garrison at Butuan at the head of the Agusan River.

The attack on Butuan was a lesson in working with untrained guerrilla fighters, most of who were unarmed and ran at the first shot. Initially the town was taken, but the Japanese garrison took defensive positions in a concrete schoolhouse. Lacking any heavy weapons to assault the schoolhouse, the attack became a stand off and the guerrillas had to retreat before Japanese reinforcements could arrive. The guerrillas captured a number of ocean going boats and freed future Leyte guerrilla leader Ruperto Kangleon from the Butuan prison, and though they could not take the town, the Japanese garrison was removed a short time later.

March 1943 was when everything changed in the guerrilla war on Mindanao, for this is when the first submarine from Australia arrived on the south coast of Mindanao. Carrying Lt. Commander Charles “Chick” Parsons and Captain Charles M. Smith, a dozen radio sets with generators and a few tons of supplies, the arrival of the submarine USS Tambor on 5 March was the first sign to Filipinos and Americans on Mindanao that they had not been forgotten and “the Aid” was finally going to come. The “bamboo telegraph” was again active and it didn’t take long for word to reach the 110th Division. Childress set out for Fertig’s headquarters at Jimenez to find out what was going on and what supplies might be available for the 110th. Childress arrived only to be volunteered to accompany Parsons on his trip across Mindanao and up to the island of Leyte.

Parsons and Smith had not just come to Mindanao to bring supplies. They had come to assess Fertig and his organization and to establish coast watcher stations on the islands of Mindanao and Leyte. Lt. Colonel Charlie Smith knew Fertig fairly well, having hid in the jungles of Mindanao with him after the surrender, and he was convinced of his ability. (See New Acquisitions, RG-106, Papers of Lt. Col. Charles M. Smith) MacArthur’s headquarters, however, was staffed with career U.S. Army soldiers who were disgusted at someone promoting himself to General. They needed reassurance that Fertig was stable. Parsons, like Smith, had no problem with Fertig and found him most capable. That established they began the next leg of their journey. Smith went to Davao, Mindanao to set up a coast watcher station and Parsons travelled to Leyte to do the same. Childress and a few of his men acted as Parsons’ guide and muscle.

Up until June 1943, 10th Military District guerrillas roamed at will right out in the open. Once the Philippines had surrendered, most of the Japanese forces moved on to the Southwest Pacific fighting in the Solomon Islands and New Guinea. Mindanao became a backwater and the Japanese did not have the forces to put large garrisons in the towns. Once a submarine from Australia landed, however, that changed the whole dynamic and the Japanese decided to move against Fertig’s organization. On June 30th they moved into the Misamis Occidental region in force and Fertig’s men scattered before the onslaught. Fertig had to move his headquarters to the area of Lanao that was to the east of Misamis Occidental. By November 1943, however, the Japanese pressure on Lanao was growing and Fertig again moved his headquarters. This time he moved to the Agusan region of Mindanao, which was the area controlled by McLish and Childress.

After the success of the USS Tambor mission that brought Lt. Cmdr. Parsons and Captain Smith to Mindanao, submarine supply missions became more frequent to the Philippine islands. Once the U.S. Navy saw the benefit of the coast watcher stations set up by Parsons and Smith, they were more than willing to provide more submarines for guerrilla supply. Two of the biggest submarines in the U.S. Navy, the USS Narwhal and USS Nautilus, began regular missions to the Philippines and it was in the Agusan region of the 110th Division that they made most of their runs in late 1943 and early 1944. McLish and Childress, therefore, became the supply quartermasters for Mindanao. They would receive the supplies, store them in safety, and then make sure they got to the other guerrillas on the island.

By early 1944 the area controlled by the 110th Division became too great and it was decided to create a new command to oversee the southern regions of Mindanao surrounding Davao. The new command was to be the 107th Division and Clyde Childress, now a Lt. Colonel, was given command. His main objective was the protection of Fertig’s new headquarters deep in the interior of Mindanao at the town of Waloe on the Agusan River. It was in this pursuit that Clyde Childress won the Silver Star Medal for gallantry in action.

In March 1944 the Japanese forces made a huge push into the Agusan region of Mindanao. They had learned that supply submarines had been arriving there and also that Fertig had moved his headquarters to that area. Pushing up the west bank of the Agusan River they were met by the forces of Major Khalil Khodr, a regimental commander of the 110th Division. On March 17th, Lt. Col. Childress arrived with some forces of his 107th Division. There at the battle of Vitos Hill, Childress singlehandedly manned a 37mm artillery piece and drove off the Japanese as his and Khodr’s men captured the hill. Childress was awarded the Silver Star for this action.

Throughout the guerrilla war on Mindanao, Colonel Wendell Fertig leaned heavily upon the talents of Childress and McLish, but as the war progressed he developed a deep distrust of them. It was a process he would repeat with many of the men he led on Mindanao. His reports on the two men were always glowing, yet in his diary he would gripe or demean things they did. Face to face, Fertig was friendly, but behind their backs he “bad mouthed” them to headquarters and other guerrillas. After MacArthur’s return to the Philippines with the landing on the island of Leyte in October, 1944, many of the guerrillas wanted to rejoin the American forces and leave the stress filled life of a guerrilla; always looking over your shoulder, eating next to nothing, and always suffering from some tropical ailment. McLish and Childress both opted to leave Mindanao shortly after the return of the Americans. In December 1944, both Childress and McLish left Mindanao by PT boat for American headquarters at Leyte. Both arrived on Leyte to find that Fertig had stabbed them in the back. He had sent reports saying they were disloyal, incompetent, and had done little for the effort in Mindanao. It was a bitter pill to swallow for the two men who had done more for the guerrilla effort on Mindanao than perhaps any other soldiers.
