What is the dive like?

We begin in the high desert plateau of Eastern Washington, overlooking the Columbia River. As we drive through the middle of what looks like a steel scrapyard of rusting farm machinery and other derilect equipment, a massive concrete launch doors appears. Then two more identical ones. Next, a massive ravine, dug by a zealous farmer opens before us. Driving down into this man-made canyon, we stop at a huge mangled 'tube' erupting from the depths. This is the entrance to the Titan I complex.

We set up gear on large wood decks by the entrance. Extra bottles, lights, fins, masks and various cameras and miscellaneous gear are lowered down into the 'hole'. Most divers opt to wear their assembled scuba unit down the ladder, but they can be lowered by rope.

At the base of the access tube is the "ready room". This is the staging area for the dive. Sevaral large benches line the walls of the room, allowing plenty of space to get your gear assembled. Once everyone is geared up and checks are complete, the walk to the launch silos begins.

The tunnels leading to the Launcher areas of the silo complex have been ravaged by salvagers in the 60's when the base was decomissioned and sold. Deck plates on the tunnel floors have been removed, leaving a network of large pipes, valves and occasional beams to walk on. Water fills the tunnels to about waist level. Inflating BCs is a must on this walk, along with listening to the person in front of us as they call out obstacles. A kayak makes the trip with us to carry all loose items like fins and cameras.

After a couple of turns and tunnel junctions we reach the area where we do our final gear-up for the dive. Fortunately the deck plates are in place here, giving us a smooth and even floor for final preparations.

Moving into the launch silo, we pass through a rather normal looking double-doorway. Judging by the doors, you'd never know you were about to enter a 160 foot tall chamber that housed a ballistic nuclear missile!

To the right a 24 inch wide plank leads across the now-empty elevator shaft that serviced the different levels of the cribwork. Watch your step. The bottom of the shaft is 110 feet straight down! (another reason our BCs are inflated!) We are standing on the massive steel cribwork that lifted the 100 ft, 110 ton ICBM to the surface for launch. It has waited in the pitch black darkness for almost 50 years.

Now we are in the heart of the complex - standing on a platform extending out into the missile launch silo, mere inches from where the massive Titan I ICBM once stood at the ready. Looking over the edge, we can see the steel structure disappearing at the limits our flashlights. The water is clean groundwater, seeping in since the Air Force turned the pumps off in the early 60's.

Masks on, regulators in, vent air from your BC, and begin the decent into Cold War history.

Now the real adventure begins!


What people say about the Silo Dive:

"What and amazing experience! I dove an ultra top secret missile silo that is now abandoned and full of water. Crazy this was just 40 mins away from were I live. Amazingly awesome experience. Thanks Undersea Adventures in Kennewick." @ Royal City, Washington. -Skyler Eppich

"Wiring sleeves still lined the walls and could still lead you to the "DANGER HIGH VOLTAGE" signs littering the steel cage. Light fixtures lined the walls, an eyewash station with shower stood at ready near the elevator shaft... powerboxes and outlets still furnishing the recesses."

-Scuba Diving a Titan I ICBM Complex by Dan Warter, DCS Films

"The experience is like a night dive, a wreck dive and if you choose, a deep dive all in one."
-Northwest Dive News, November 2010

"The missile silo is a bucket list dive that delivers! I felt like an adventuresome 12 year old walking in to a labyrinth netherworld. Giddy with excitement i wove through rusted and sometimes twisted passages! Thanks Don!" -Joel Norton

When asked what we could do to improve the experience: "Don't change a thing, leave it just as they left it. This is History."
-Brian Strack, Seven Seas Scuba
