Most of the combat troops were Special Forces soldiers deployed deep into hostile territory as combat multipliers.

Their mission was to train indigenous troops to fight the Viet Cong guerillas.

It was messy, horrible work in incredibly dangerous spaces.

In this photograph, we see a restored Douglas AC-47 Spooky in flight over Kansas in the United States of America. It sports a woodland type camouflage paint scheme that was used in the Vietnam War. AC-47 gunships were often called on to support troops in the field where artillery could not reach. Also, they were excellent for air base and fire base defense. Firebases in the U.S.-involvement Vietnam War, were a type of military base,. It may refer to: Firebase 6, Central Highlands Firebase Airborne, central South Vietnam Firebase Argonne, Quảng Trị Province Firebase Atkinson, southwest South Vietnam Firebase Bastogne, Thua Thien Province Firebase Berchtesgaden Thừa Thiên–Huế Firebase Betty, Bình Thuận Province Firebase Bird or other southern South Vietnam Firebase.

A saving grace was the ready availability of American air support.

The VC were desperate to crush these interlopers before they could gain a solid foothold.

The stage was set for an epic scrap.

In this digital picture,  we see an AC-47 gunship flying near Saigon, South Vietnam during the Vietnam War. Also known as “Puff the Magic Dragon,” these aircraft typically had three 7.62 mm miniguns mounted on the left side of the aircraft. The aircraft carried up to 8 crew members including the pilot and was the start of a robust gunship program in the United States military. A gunship is a military aircraft armed with heavy aircraft guns, primarily intended for attacking ground targets either as airstrike or as close air support.

What had begun as an apparent harassment and probing attack was rapidly evolving into something altogether worse.

Charlie owned the night, and he knew it.

Things were looking bleak.

In this image, we see a Douglas AC-47D gunship with its three main guns visible. The AC-47 was based on the C-47 Skytrain, a transport plane used by all branches of the U.S. military in World War II. The Douglas C-47 Skytrain or Dakota is a military transport aircraft developed from the civilian Douglas DC-3 airliner. It was used extensively by the Allies during World War II. As an aerial gunship platform, it excelled.

The American defenders, like the VC they were facing, were more accustomed to jets.

All involved were put a bit off balance by this new development.

Crouching in the jungle, the ample VC attack force was poised for its final push.

AC-47 flight crew and minigunsIn this photo we see six members of an AC-47 crew. Flight crews typically consisted of seven men — sometimes 8. They were part of the 4th Air Commando Squadron, the first unit to field the AC-47. Initially, it had five converted C-47s. The squadron was later renamed and eventually became the 4th Special Operations Squadron. It continues to operate today using Lockheed AC-130J aircraft to provide close air support and other special operations missions. The 4th is based at Hulburt Field in Florida.

By dawn, the VC commander expected to see his communist flag raised over the American command bunker.

And then everything changed.

Suddenly and without warning, .30-caliber machine gun rounds began sleeting from above like a deluge.

In this picture, we see streaks of red from tracer rounds fired by an AC-47 gunship in the defense of Tan Son Nhut Air Base during the Tet Offensive in 1968. Tan Son Nhut Air Base was a Republic of Vietnam Air Force facility. It was located near the city of Saigon in southern Vietnam. The United States used it as a major base during the Vietnam War, stationing Army, Air Force, Navy, and Marine units there. Following the Fall of Saigon, it was taken over as a Vietnam People’s Air Force facility and remains in use today. Tan Son Nhat International Airport, has been a major Vietnamese civil airport since the 1920s. The Tet Offensive was a major escalation and one of the largest military campaigns of the Vietnam War. The Viet Cong and North Vietnamese People’s Army of Vietnam launched a sneak attack on January 30, 1968, against the forces of the South Vietnamese Army of the Republic of Vietnam, the United States Armed Forces and their allies.

In moments the orbiting aircraft had expended some 4,500 rounds and broken the back of the VC attack.

Charlie had just gotten his first rude introduction to Puff, the Magic Dragon.

The first testbed was actually Project Tailchaser under the command of Air Force Captain John Simons.

In this photograph we see a GAU-2/A minigun on an early prototype mount in the doorway of a AC-47 gunship. Early mounts like this one were improvised by crews in the field. The M134 Minigun is an American 7.62×51mm NATO six-barrel rotary machine gun with a high rate of fire. It features a Gatling-style rotating barrel assembly with an external power source, normally an electric motor. It was designed and manufactured by the General Electric company.

Three GAU-2/A rotary machine guns were mounted in a C-47 to transform the plane into a gunship. The GAU-2/A was the Air Force name for the General Electric M134 Minigun. Image: U.S. Air Force

In practice, the concept was effective beyond their wildest expectations.

It really all came down to physics.

This image shows three M134 Miniguns on standardized mounts with control panels. As the Air Force establish an AC-47 squadron, it needed to standardize the equipment and methods of operation in the gunship role. Air Force Systems Command played a large role in the operational history of the 14th Air Commando Wing and was a large part of why gunship trials were so successful.

He then fired the weapon and made a grease pencil mark on the side windscreen where the bullets struck.

By some basic pilotage he could adjust the fall of his rounds based upon how he orchestrated his turn.

The success of that test led to the subsequent Project Gunship in October of 1964.

In this image we see an AC-47 that is being given to the South Vietnam Air Force. These planes were provided to South Vietnam and Laos as part of President Nixon’s Vietnamization policy on the Vietnam War to beat North Vietnam. AC-47 planes were also provided to the Colombian Air Force, Royal Lao Air Force and Royal Thai Air Force. Vietnamization was a policy of the Richard Nixon administration to end U.S. involvement in the Vietnam War through a program to “expand, equip, and train South Vietnamese forces and assign to them an ever-increasing combat role, at the same time steadily reducing the number of U.S. combat troops”.

Project Gunship involved mounting three miniguns in the cargo compartment of a Douglas C-47 Skytrain.

The C-47 Skytrain was the same lumbering cargo aircraft that took American paratroopers intoNormandy on D-Day.

Initial tests involved simply securing standard external minigun pods in place with tiedown straps.

In this photo, we see three Air Force crewmen loading belts of 7.62x51 NATO ammunition into the M134 Miniguns of an AC-47 gunship. Called the AC-47, it was the first fixed-wing aircraft set up as a gunship as part of an Air Force mission to provide close air support to troops in contact throughout South Vietnam. The Air Force used a total of five aircraft to form the first gunship squadron. As new aircraft came onto Nha Trang Air Base, they were folded into the squadron.

Later versions used improvised and eventually standardized fixed mounts.

At its maximum cyclic rate this improvised gunship spewed some 300 rounds per second.

With a little practice, the subsequent bang out-classified AC-47 was devastating.

This photo is of an AC-47 gunner in the rear of the aircraft. He is preparing to drop a military illumination flare from an AC-47 aircraft. In the time before the widespread use of night vision equipment, adding light to the night was the only way Americans could see the enemy. A flare, also sometimes called a fusée, fusee, or bengala, bengalo in several European countries, is a type of pyrotechnic that produces a bright light or intense heat without an explosion.

The operators behind Project Gunship outfitted two C-47 aircraft but then ran out of miniguns.

The GAU-2/A was a relatively new weapon, and everybody wanted them.

As a stopgap, the Gunship crews substituted tenAN/M2 .30-caliber Browning machineguns.

In this photograph, we see Airman 1st Class John Levitow. Levitow is wearing his uniform, an Air Force flight suit, and a radio headset so he can communicate with the pilot and other members of his military unit. Levitow received the Medal of Honor for gallantry in combat during a military operation on February 24, 1969.

However, these recoil-operated weapons jammed frequently using the WWII and Korean War surplus ammo available at the time.

They also filled the main cabin with noxious fumes.

Additionally, these 10 conventional machineguns could only produce the fire density of a single minigun.

In this photo we see a AC-47 and AC-130 flying in formation in 2021. The memorial flight was in memory of Airman 1st Class John Levitow who was awarded the Medal of Honor.

The attack profile typically put the airplane in a left-hand orbit at 120 knots and 3,000 feet.

A skilled pilot could saturate every square yard of a football field-sized space in under 10 seconds.

The basic combat load was 45 flares and some 24,000 rounds of ammunition.

The plane itself could loiter on station for hours.

The AC-47 used the call sign Spooky.

Ground troops fell madly in love with the machines.

The AC-47 flew mostly at night to avoid ground fire.

Once the crews got synchronized with the supported troops, Puff turned into a proper monster.

The plane orbited above the battlefield for more than four hours and burned through 20,500 rounds.

A dozen were lost in combat.

The lessons learned in combat by the crews of the AC-47s eventually informed the development of theAC-130 Spectre.

Spectre remains at the very tip of the spear even today this deep into the Information Age.
