Imagine standing on a muddy runway in 1944. You're watching a twin-engine beast roar to life, its two Pratt & Whitney R-2800 Double Wasp radials spitting blue flames and enough noise to rattle your teeth. This isn't just another bomber. It's the Douglas A-26B Invader, an aircraft so fast and so violent that it basically redefined what "ground support" looked like for the next thirty years.
Honestly, it’s one of those rare machines that actually lived up to its name.
While most people associate the "B-26" moniker with the Martin Marauder—a fine plane with a bit of a murderous reputation for rookie pilots—the Douglas A-26 was a completely different animal. It was leaner. It was meaner. Most importantly, it was the only American bomber to serve through World War II, the Korean War, and the Vietnam War. That kind of longevity doesn't happen by accident. It happens because the thing was built like a brick outhouse and armed like a floating gun battery.
The "Six-Gun Nose" and Pure Firepower
What makes the "B" model specifically so iconic is the nose. While the A-26C had a "glass" nose for a bombardier using a Norden bombsight, the A-26B was designed for the guys who liked to get their hands dirty.
Basically, Douglas gave it a "solid" nose.

Inside that nose, they crammed six—and later, eight—.50 caliber Browning machine guns. If you've ever seen one of these things in person, it’s intimidating. You’re looking at a light bomber that can throw lead like a heavy fighter. But they didn't stop there. By the time you added the internal wing guns and the underwing gun pods, some configurations of the Douglas A-26B Invader were packing 14 separate .50 cal machine guns all firing forward.
That’s not an airplane; that’s a flying scythe.
Technical Breakdown (The Nerdy Bits)
If you're into the specs, the numbers are still impressive even by modern standards. We're talking about a plane that could hit 355 mph while carrying 6,000 lbs of bombs. To put that in perspective, it was faster than many of the fighters it was supposed to be hiding from.
- Engines: 2 × Pratt & Whitney R-2800-79 (2,000 hp each).
- Max Weight: Around 35,000 lbs when fully loaded for a fight.
- Wingspan: 70 feet of high-speed laminar flow wing.
- Crew: Usually 3 (Pilot, Navigator/Loader, and a Gunner for the remote turrets).
The remote turrets were actually a huge piece of tech for the 1940s. The gunner sat in a station behind the pilot and used a periscopic sight to aim dual .50 cal turrets on the top and bottom of the fuselage. It was complicated, sure, but it kept the profile of the plane incredibly sleek.
What Most People Get Wrong About the Combat Record
You'll often hear that the Invader was a "late arrival" in WWII. While true—it didn't see real action until mid-1944—its impact in the European Theater was massive. The Ninth Air Force absolutely loved them. They used them for low-level "interdiction" missions, which is just a fancy military word for blowing up trains, trucks, and anything else trying to move German supplies to the front.

But the Pacific was a different story.
General George Kenney, the big boss of the Far East Air Forces, famously hated the early A-26. He actually said, "We do not want the A-26 under any circumstances." Why? Because the original cockpit canopy had terrible visibility for the pilot, especially looking down and to the sides. If you're flying 300 mph at tree-top level trying to hit a Japanese pillbox, you kinda need to see where you're going.
Douglas eventually fixed this with a "clamshell" canopy that gave the pilot a much better view, but the early bad reviews stuck for a while.
The Long Shadow: Korea and Vietnam
The Douglas A-26B Invader really found its soul in the Korean War. By then, it had been redesignated as the B-26 (because the Martin Marauder was retired and the Air Force wanted to simplify things). It became the king of the night.
North Korean and Chinese forces moved mostly under the cover of darkness to avoid jet fighters. The Invaders, equipped with radar and those massive nose guns, would loiter over supply routes and just dismantle convoys. They were the original "night intruders."
Then came Vietnam.
By the 1960s, these airframes were ancient. But the Air Force needed something that could carry a heavy load and stay over the Ho Chi Minh Trail for hours. They went back to the Invader. They even built a specialized version called the B-26K Counter Invader (later renamed A-26A to keep the Thai government happy, since they didn't allow "bombers" on their soil). These planes had beefed-up wings, wingtip fuel tanks, and even more hardpoints for rockets and napalm.
It’s wild to think that a plane designed in 1941 was still killing tanks in 1969.

Why It Still Matters Today
You might wonder why we’re still talking about a prop-driven bomber in the age of stealth drones. Honestly, the A-26 represents a peak in "multi-role" design. It was a bomber that could dogfight, a strafer that could carry torpedoes, and a reconnaissance platform that could outrun interceptors.
After the military was done with them, they didn't just go to the scrap heap.
A lot of them became fire bombers. If you live in the Western US or Canada, there’s a good chance an A-26 saved someone’s house in the 70s or 80s. Their speed and payload made them perfect for dropping retardant on forest fires. Companies like Air Spray Ltd. flew them well into the 2000s.
Today, if you want to see one, you’ve got to head to places like the National Museum of the USAF or catch a flight with the Commemorative Air Force. Seeing a "solid nose" A-26B on the ramp is a reminder of an era where "overwhelming firepower" wasn't just a slogan—it was the design philosophy.
Actionable Insights for History Buffs
If you're looking to dive deeper into the history of this aircraft, don't just stick to Wikipedia. There are a few things you can do to really "get" the Invader:
- Check the Serial Numbers: If you find an A-26 at an airshow, look for the serial. Many "B" models were converted to "C" models and back again. The noses were interchangeable! You can often find the original designation hidden in the maintenance logs or data plates.
- Visit the Mid-Atlantic Air Museum: They have a fantastic example, and the staff there can explain the specific mechanics of the remote-controlled turrets, which are usually what trip people up.
- Search for "On Mark" Conversions: After the war, many A-26s were turned into high-speed executive transports. They look like something out of a James Bond movie—sleek, fast, and surprisingly luxurious for a former death machine.
The Douglas A-26B Invader wasn't just a plane; it was a survivor. It adapted when the jet age tried to make it obsolete, and it stayed in the fight long after its peers were turned into soda cans.
