- The Douglas AD Skyraider, also known as the A-1 Skyraider is an American single-seat attack aircraft in service from 1946 to the early 1980s. The Skyraider had a remarkably long and successful career well into the Jet Age (when most piston-engined attack or fighter aircraft were replaced by Jet aircraft) thus becoming known by some as an "anachronism". The aircraft was nicknamed "Spad", after the French World War I fighter.
It was operated by the United States Navy (USN), the United States Marine Corps (USMC), and the United States Air Force (USAF), and also saw service with the British Royal Navy, the French Air Force, the Republic of Vietnam Air Force (RVNAF), and others. It remained in U.S. service until the early 1970s.
The jet powered A-10 Thunderbolt II was based on specifications for a modernized Skyraider with a heavy payload and good endurance.
The piston-engined propeller Skyraider was designed during World War II to meet United States Navy requirements for a carrier-based, single-seat, long-range, high performance dive/torpedo bomber, to follow on from earlier aircraft such as the Douglas SBD Dauntless, the Curtiss SB2C Helldiver and the Grumman TBF Avenger. Designed by Ed Heinemann of the Douglas Aircraft Company, prototypes were ordered on 6 July 1944 as the XBT2D-1. The XBT2D-1 made its first flight on 18 March 1945, and the USN began evaluation of the aircraft at the Naval Air Test Center (NATC) in April 1945. In December 1946, after a designation change to AD-1, delivery of the first production aircraft to a fleet squadron was made to VA-19A.
The AD-1 was built at Douglas's El Segundo plant in Southern California. In his memoir The Lonely Sky, test pilot Bill Bridgeman described the routine yet sometimes hazardous work of certifying AD-1s fresh off the assembly line at a rate of two aircraft per day for delivery to the U.S. Navy in 1949 and 1950.
A Douglas XBT2D-1 Skyraider prototype
The low-wing monoplane design started with a Wright R-3350 Duplex-Cyclone radial engine which was later upgraded several times. The aircraft had distinctive large straight wings with seven hardpoints apiece. The Skyraider had excellent maneuverability at low speed, and carried a large amount of ordnance over a considerable combat radius. It had a long loiter time for its size, compared to much heavier subsonic or supersonic jets. The aircraft was optimized for ground attack and was armored against ground fire in key locations, unlike faster fighters adapted to carry bombs, such as the Vought F4U Corsair or North American P-51 Mustang, which were retired by U.S. forces before the 1960s.
Shortly after Heinemann began designing the XBT2D-1, a study was issued showing that for every 100 lb (45 kg) of weight reduction, the takeoff run was decreased by 8 ft (2.4 m), the combat radius increased by 22 mi (35 km) and the rate-of-climb increased by 18 ft/min (0.091 m/s). Heinemann immediately had his design engineers begin a program for finding weight savings on the XBT2D-1 design, no matter how small. Simplifying the fuel system resulted in a reduction of 270 lb (120 kg); 200 lb (91 kg) by eliminating an internal bomb bay and hanging external stores from the wings or fuselage; 70 lb (32 kg) by using a fuselage dive brake; and 100 lb (45 kg) by using an older tailwheel design. In the end, Heinemann and his design engineers achieved more than 1,800 lb (820 kg) of weight reduction on the original XBT2D-1 design.
The Navy AD series was initially painted in ANA 623 glossy sea blue, but during the 1950s, following the Korean War, the color scheme was changed to light gull grey and white (Fed Std 595 27875). Initially using the gray and white Navy scheme, by 1967 the USAF began to paint its Skyraiders in a camouflaged pattern using two shades of green, and one of tan.

My dad was a skyraider pilot in Vietnam, Major San Hong (Hồng Khắc San). Great memory when watching this video 👍❤️👍
Too bad that Gen. Aderholt wasn't in charge of the Afghanistan withdrawal. Those billions of dollars of equipment should have been permanently disabled.
The illegal VN war where 58,000 men and women lost their lives.
I'm still learning about the Vietnam War. Born in '62 loving all things aviation, I built a model of this plane but never really looked up it's long history. Thank you first to our veterans who served especially in Nam who gave everything to save the South Vietnam people and endure the scorn of their own American people. What a hell hole that must have been. Thank you to this channel to show the real life of American pilots during that war and the planes that were used to get the job done. Awesome video!!🇺🇸🇺🇸
As a 75 year old Vietnam era veteran and a big big fan of the Skyraider, this was a fantastic piece. Great pictures but even greater stories of the men closely associated with the aircraft and many stories you will never hear anywhere except from those who were there. Great job all. Hand salute!!!
I was a crew chief on the the A-1E Skyraider at NKP in 1968/69. Best plane I worked on during my time in the Airforce! I couldn't believe the number of bullet holes they would have when they'd come back from a mission! I'm 78 years old now, but I still, fondly, remember that A-1E!!
Probably the best piston engined attack aircraft ever produced. Extremely durable and excellent loiter time on target. I would give a piece of my anatomy to be able to own one today.
The one bit of naval ordinance he forgot was a toilet
ABH3 boatswain mate here I lived and breathed these plans. fueled them, armed them. shot them off and washed them, and hid in them to get some sleep. they were bad to the bone.
We fail to recognize the huge contribution the Douglas company has given to the USA. The "Spad" was a lifesaver for many US military personnel. They were pretty much gone by the time I was commissioned as an Ensign. But by then (1977) we had the little A-4 that deserves to be remembered as well. My CO flew the A-4 in Vietnam and he took a hit, a bad one. Captain Conner (USN) flew that tiny jet, upside-down, home to our ship. He became a legend. Never forget what these men did! I never will.
I flew two tours in Vietnam, my second was up on the DMZ, 71-72. I was part of an Air Cavalry troop stationed up there, and was the 'Hunter' in a Hunter-killer team. During both tours, I witnessed the unreal capabilities of the "Spad-Flying dump truck-Sandy, etc many times. I always marveled as to how long they could stay 'on station' and they never seemed to run out of ordinance to shoot, or drop. Just amazing what those skilled pilots could do with that particular aircraft. I thank you all of the 'spad drivers' who may read this, and I offer a very humble, "thank you", for saving my ass MANY TIMES. A slow hand salute to all of you. God bless.
What a chonky, beauty of a plane. If the Skyraider had an ancient equivalent it would be a charging war horse
Years ago I spoke with a former Skyraider pilot. He said, "We called it the flying dump truck." It could haul a load.
The best attack aircraft in history. The A10 is a close second. I would love to own one of these beasts. All the best technology from the piston aircraft era.
Out of all the piston engine aircraft of their time, the F4U Corsair and A1 Skyraider are my favorites.
I was a Crew Chief with the 6th SOS, Pleiku, Vietnam in 1969. Best aircraft I ever worked on .
Thanx for providing us old school folk these docco’s.
As a kid, my grandad had a book aircraft of the Vietnam war, and the A-1 in it single seat, and multi seat aircraft was my favorite! I would draw, and color the A-1 when it was raining, then at the age of 32 finally saw it in person! There’s nothing like it in the world. Wish more were saved, but very thankful that some were saved!
Beast of an aircraft.
