The 1960s folk song “Puff, the Magic Dragon“ became wildly popular thanks to Peter, Paul, and Mary—but during the Vietnam War, the name took on a very different meaning. It was adopted by U.S. troops to describe the Douglas AC-47 ‘Spooky,’ the first fixed-wing gunship used in Southeast Asia.
Originally built as a cargo aircraft, the AC-47 was later transformed into a flying fortress, equipped with side-mounted, rapid-firing guns. These guns could unleash a devastating amount of firepower, lighting up the night sky with glowing red streaks. From the ground, it looked like a dragon breathing fire—earning the aircraft its fiery nickname: Puff, the Magic Dragon. This gunship laid the foundation for future aircraft like the Lockheed AC-130, setting a new standard for aerial fire support.
Deployment of Douglas C-47 Skytrains to Vietnam

The predecessor to the AC-47 Spooky was the two-engined Douglas C-47 Skytrain, which was flown extensively by the Allies during the Second World War. The C-47 was brought to Vietnam in November 1961, but was mainly flown as a transport and cargo gunship by the Americans.
Many C-47s were outfitted as “flare ships” and designated FC-47s (“F” for flare, in this case). They’d drop parachute flares over enemy positions during night attacks, and, by November 1963, had deployed more than 7,000.
Development of the Douglas AC-47 Spooky

By 1963, the Viet Cong had escalated their guerrilla tactics under the cover of night, underscoring the need for American forces to develop a more effective nighttime air strategy. After careful deliberation, the U.S. Air Force adopted the concept of what is now considered the modern fixed-wing gunship.
This concept involves a fixed-wing aircraft equipped with heavy armaments mounted on the sides for side-firing operations. Although the idea of side-firing gunships had been proposed in the years before World War II, it wasn’t until 1963 that the concept came to fruition.
The C-47 Skytrain was selected as the test platform for the first fixed-wing gunship because it met all the necessary criteria. The success of this gunship design was based on the aircraft’s ability to deliver concentrated fire on enemy targets while also providing enough power and space to carry the necessary weaponry. As a cargo plane, the C-47 was capable of transporting large loads of munitions, and its propeller-driven design offered the maneuverability needed for such precise operations.
‘Spooky’ experiments

By mid-December 1964, modifications to the C-47 Skytrain were completed. Initially, this new type of aircraft was designated the FC-47, for “fighter/cargo.” However, fighter pilots were upset with the “fighter” categorization; they refused to believe that a slow cargo aircraft could be a fighter. To appease them, the new aircraft was designated AC-47, meaning “attack/cargo.”
Testing of the AC-47 began in Vietnam in late 1964. On December 14, it flew its first daytime combat mission, firing on enemy boats, trails and staging areas. The aircraft’s first night mission occurred on December 23, 1964. During the attack, the AC-47 fired over 4,500 rounds of ammunition and dropped a total of 17 flares. Its efforts successfully halted the Viet Cong assault.
The AC-47 continued to be successfully tested throughout early 1965. In fact, these trials were so successful that an AC-47 was sent to the United States to provide crew training. That July, the US Air Force ordered officers with Training, Advising and Counseling (TAC) to establish an AC-47 squadron. In August, the 4th Air Commando Squadron was created. It operated five aircraft upon its inception, with 26 equipped by the end of the year.
Weaponizing the Douglas AC-47 Spooky

The C-47 Skytrain’s appearance didn’t change when it was modified into an attack aircraft. Inside, three M134 Miniguns were installed to fire through two rear window openings and the side cargo door, all positioned on the aircraft’s left side, where the pilot sits.
Mounting the weapons on the left side was crucial for providing close-air support to ground troops. The Miniguns had a blazing-fast rate-of-fire of 6,000 RPM, enough to cover an entire football field in just one minute. A MK.20 Mod.4 gunsight was also added to the left cockpit window.
Both the pilot and the gunners could operate the Miniguns, but the pilot usually fired them since the controls were built into the yoke. The gunners’ main role on the AC-47 was to monitor the guns and perform any necessary maintenance.
From ‘Spooky’ to ‘Puff’

As the AC-47 Spooky proved itself in combat, its nickname “Puff, the Magic Dragon” became even more fitting. Ground troops originally coined the term not just because of the red-hot tracers streaming through the night sky, but also due to the deafening roar of its M134 Miniguns—reminiscent of a dragon’s growl. The name caught on so widely that in some regions, the aircraft’s official designation was even changed from Spooky to Puff.
With growing demand, the 4th Air Commando Squadron began deploying the AC-47 to key bases across South Vietnam, including Nha Trang, Đà Nẵng, Pleiku, Biên Hòa, and Binh Thuy. In 1966 alone, the squadron flew 277 combat missions, unleashing 137,136 rounds and dropping 2,548 flares to support ground operations.
In this early stage, only two AC-47s were lost, which boosted confidence in the aircraft’s durability and effectiveness. Over the course of approximately 4,000 missions in South Vietnam and Laos, the AC-47 reportedly took out more than 5,300 enemy fighters—cementing its legacy as a game-changer in aerial fire support.
Replaced by newer, more modern gunships

By 1969, the Ac-47 Spooky was beginning to show extreme wear and tear. It wasn’t practical to keep rebuilding and maintaining the gunships, especially as the more sophisticated AC-130 and Fairchild AC-119s were beginning to arrive in Vietnam.
Slowly, Puff, the Magic Dragon was transitioned out of mainstream use, and the last American AC-47 combat mission happened on December 1, 1969. Of the 53 delivered to Vietnam, about 41 of them saw combat during the Vietnam War.
The AC-47 was eventually replaced first with the Lockheed AC-130A Spectre, followed by the AC-119G Shadow, AC-119K Stinger and, finally, the AC-130E Pave Spectre. While these gunships were more modern, they wouldn’t have been as effective if it hadn’t been for the success of Puff, the Magic Dragon.
Other nations have equipped the Douglas AC-47 Spooky

While the US Air Force retired the AC-47 Spooky from active duty, other air forces worldwide have – and still – equip the aircraft. In December 1984 and January ’85, the United States supplied two to El Salvador and trained crews on how to operate them. As well, Thailand, Cambodia, South Africa and Uruguay were among the countries to once fly the gunship.

Currently, the Columbian Air Force is the only one to still fly the AC-47, a variant known as the Basler BT-67. The 214th Tactical Air Support Squadron has about six in its inventory.
