If you’re driving down East Valencia Road in Tucson, you’ll eventually hit a point where the horizon just... stops being desert. Instead of saguaros and scrub, you see tails. Thousands of them. Rows upon rows of vertical stabilizers poking up like shark fins in a sea of sand. This is the aircraft graveyard in Tucson, or as the military officially calls it, the 309th Aerospace Maintenance and Regeneration Group (AMARG). It’s huge. Honestly, "huge" doesn't even do it justice. We’re talking about 2,600 acres of land packed with roughly 4,000 aircraft.
Why Tucson? It isn't just because the scenery is nice. The Sonoran Desert has a very specific "caliche" soil—a hard, alkaline layer under the topsoil. It’s basically natural concrete. You can park a 200,000-pound B-52 Stratofortress on it, and it won't sink. Plus, the humidity is practically non-existent. In other parts of the world, metal starts weeping rust the second it sits still. Here? Things stay preserved.
The Massive Scale of the Boneyard
Walking the perimeter—because you can't just wander inside anymore without a very specific reason—you start to realize the sheer variety of what’s parked there. It isn't just old junk. You’ve got F-16 Fighting Falcons that look like they could take off tomorrow. Right next to them, you might see a C-5 Galaxy that's been stripped so thoroughly it looks like a picked-over Thanksgiving turkey.
The 309th AMARG is part of Davis-Monthan Air Force Base. It started right after World War II. The government had all these surplus C-47s and B-29s and nowhere to put them. Tucson was the answer. Since then, every branch of the U.S. military (and some federal agencies like NASA) has sent their retirees here.
It’s not a dump. That’s the biggest misconception people have. It’s more like a giant, very organized organ donor bank. If an active-duty F-15 in Okinawa needs a specific bracket that isn't manufactured anymore, the guys at AMARG go out into the heat, unscrew it from a mothballed jet, refurbish it, and ship it out. It saves the taxpayers billions. Seriously, billions. In a typical year, this facility returns over $500 million worth of spare parts back into the inventory.
How They Actually "Store" a Plane
You can’t just turn off the engine and walk away. If you did, the desert sun would cook the interior to 200 degrees and melt the avionics. The process is actually pretty intense. First, they flush out the fuel lines and replace the fuel with a light preservative oil. Then they seal every single opening.

They use this stuff called "Spraylat." It’s a two-layer plastic coating. The first layer is black to seal things up; the second layer is white to reflect the sun. It looks like the planes are wearing giant, tight-fitting white bandages. If you see a plane at the aircraft graveyard in Tucson that’s completely white, it’s in "Type 1000" storage. That means it’s being kept in near-perfect condition because the Pentagon thinks they might need it again.
Other planes are "Type 2000" (for parts) or "Type 4000" (basically destined for the smelter). It’s a hierarchy of usefulness.
The Pima Air & Space Museum Connection
For a long time, the best way to see the boneyard was through the bus tours run by the Pima Air & Space Museum. Unfortunately, those stopped during the pandemic and haven't really come back due to security shifts at Davis-Monthan. It’s a bummer. However, the museum itself is right across the street, and it’s basically the "public-facing" version of the graveyard.
They have over 400 aircraft on 80 acres. You can walk right up to a SR-71 Blackbird. You can stand under the wing of a B-36 Peacemaker, which is so big it makes you feel like an ant. The museum is a non-profit, and it’s arguably one of the best aviation collections on the planet. If you're visiting Tucson specifically to see the graveyard, this is your home base.
Most people don't realize that the museum isn't the graveyard, but it's the only place where you can actually touch the history. The real AMARG is behind a high fence with armed guards. Don't try to hop it. They take "No Trespassing" very seriously.

What Happened to the "Celebrity" Planes?
Every now and then, a plane with a "name" ends up in Tucson. After the 1991 Gulf War, plenty of decorated airframes landed here. You might find a jet that flew a famous mission or carried a VIP. But mostly, it's about the workhorses. The A-10 Warthogs are a common sight. These "Flying Tanks" were built just up the road in some cases, and seeing them lined up by the dozens is eerie.
There’s also the "Celebrity Row." This is the section of the AMARG that is visible from the fence line or was part of the old tour route. It features one of every type of aircraft currently in storage. It’s like a Greatest Hits album of American air power.
But there’s a darker side to the graveyard—the "guillotine." Under various arms reduction treaties, like START (Strategic Arms Reduction Treaty), the U.S. had to prove it was destroying certain bombers. They used a 13,000-pound steel blade dropped from a crane to slice B-52s into pieces. They had to leave the pieces there for months so Russian satellites could photograph them and verify they were truly "dead." It’s a cold, clinical end for a machine that costs millions.
Why You Should Visit Tucson Anyway
Even if you can’t get on a bus and drive through the rows of the aircraft graveyard in Tucson, the area is an aviation geek’s paradise. The approach paths for Davis-Monthan run right over parts of the city. You’ll be eating a taco at a food truck and an F-35 will scream overhead.
Then there’s the Titan Missile Museum about 20 minutes south in Sahuarita. It’s the only remaining Titan II missile silo from the Cold War that hasn't been destroyed. You can go underground, see the control center, and look down into the silo at a (disarmed) multi-megaton nuclear missile. Between the Boneyard, Pima, and the Titan Silo, Tucson is essentially the capital of the Cold War's physical remains.

Misconceptions and Facts
- Is it open to the public? Not the AMARG itself. You can see a lot from the perimeter fences along Kolb and Irvington roads, but you cannot enter the military base without a valid DOD ID or a pre-arranged official reason.
- Do they sell planes to civilians? Kinda, but not really. You can’t just walk in and buy a P-51 Mustang. Most "disposal" happens through the Defense Logistics Agency (DLA). Often, planes are sold for scrap metal. The aluminum is melted down and turned into soda cans or new plane parts.
- Is it just U.S. planes? Mostly. But sometimes you’ll see foreign aircraft that the U.S. bought for testing or that were part of joint programs.
The scale is what usually gets people. You think you know what 4,000 planes looks like. You don't. It's a horizon of metal. It feels like a monument to a specific era of engineering. Every one of those planes has thousands of flight hours. Thousands of stories. Pilots who loved them, mechanics who cursed them. Now they just sit in the Arizona sun, waiting for a mechanic to need a bolt or a smelter to need some aluminum.
How to Get the Best Views Today
Since the official bus tours are currently offline, you have to be a bit more creative.
- The Perimeter Drive: Take Kolb Road south from 22nd Street. Drive slowly (but watch traffic). You’ll see the heavy lifters—the C-5s and C-17s. Then turn onto East Irvington Road for a view of the fighters.
- Google Earth: Honestly? It’s the best way to see the organization. From above, you can see the perfect geometric patterns the AMARG staff uses to park the planes. It looks like a circuit board made of titanium.
- Pima Air & Space Museum: As mentioned, this is the best legal way to see planes up close. They have some "boneyard" style displays where you can see how the Spraylat is applied.
- The "Fence Walk": There are dirt paths along some of the fencing where photographers hang out. If you have a decent zoom lens, you can get incredible shots without ever breaking a law.
It’s weirdly quiet out there. You’d think a place with 4,000 war machines would feel loud or aggressive. It doesn’t. It feels like a cemetery. A very hot, very dry cemetery where the residents are made of duralumin and rivets.
If you’re planning a trip, go in the winter or early spring. Tucson in July is no joke—the heat reflecting off the desert floor and the metal skins of the planes can easily push the "feels like" temperature toward 115 degrees.
Actionable Insights for Your Visit:
- Check the Museum Schedule: Before you head to the aircraft graveyard in Tucson, check the Pima Air & Space Museum website. Even though AMARG tours are paused, they often host special events or "Night at the Museum" programs that are worth your time.
- Hydrate: It sounds cliché, but the Tucson air will suck the moisture right out of you while you're standing by the fence taking photos.
- Bring Binoculars: If you’re doing the perimeter drive, a good pair of binoculars will let you see the tail numbers. You can actually look those numbers up online to see the specific history of that exact plane.
- Visit the Titan Missile Museum: It’s the perfect companion to the Boneyard. It gives you the "why" behind all those bombers sitting in the dirt.
- Stay in Downtown or the Foothills: Don't just stay at a chain hotel near the airport. Tucson has a massive food scene (it's a UNESCO City of Gastronomy). Get some Sonoran hot dogs after you're done looking at the jets.
The Boneyard isn't just a place where planes go to die. It's a massive, sleeping reserve. It’s a testament to the sheer industrial scale of the 20th century. Whether you're a history buff, a photographer, or just someone who likes looking at weird, massive things, it’s a site that stays with you. Just remember: look, don't climb.
