Dive Valhalla Missile Silo

Dive Valhalla Missile Silo | Stone Oak Scuba
January 31 – February 2 2020
$100 Non-Refundable Deposit


The US Air Force built twelve structures in the steamboat mountain range of West Texas near Abilene in which they housed ICBMs aimed at the USSR during the cold war. These missiles were 10 feet in diameter, 82 ft long, and weighed 260,000 lbs with the capability of traveling 11,500 miles at 15,000 mph. The three engines, two boosters and a sustainer were fueled by liquid oxygen and RP-1 fuel, generating 389,000 lbs of thrust. After only two years, the missiles were removed and the silos were sold for salvage. The Atlas missiles were modified and subsequently used to launch the Mercury Astronauts and over 175 other payloads into space over the next 20 years. Building the silos required moving 37,500 cubic yards of earth and pouring of 7,847 cubic yards of concrete around 1,288 tons of steel reinforcements. The silo construction (4-10 ft thick concrete with 1-4 inch rebar on 9-20 inch) was to allow this site to withstand a nearby nuclear strike and still be able to fire its missile at an enemy. Since being decommissioned, this silo has slowly filled with ground water seeping through the cement walls. 

This is an Advanced Dive 
To make this a fun and enjoyable dive you should:
1) Already have prior deep diving and limited visibility experience. We will be offering discounted prices on these specialties before the trip.
2) Correctly weighted with the gear you will be wearing to dive – a perfect buoyancy specialty might be in order.
3) Be comfortable donning and doffing your scuba gear in the water – a practice session in the pool may help.
4) Join us for our Valhalla pre-party and make a few prior dives in cooler water.
5) Be in moderately good physical shape to carry your dive gear to the dressing area and to climb up and down the stairs to get to and from the water – use the stairs instead of the elevator for a few weeks before you come.

Diving Procedures

There is a floating platform with a stairway for staging divers. Each diver carries his or her own personal diving gear. This insures the diver has all equipment available when entering water and has hands free to climb stairs. Divers don gear, do final buddy check and make a fun dive according to their dive plan. Divers complete dive, doff scuba and exit platform by climbing the stairs.

Diving Conditions

The water is fresh, clear, and cool, 58-60F, 130 ft deep and crystal clear. The silo is 60 ft in diameter. Everything from the dressing areas to the electric gear winch, lighting systems and the actual dive area is 50-70 ft underground. The ambient air is a constant 60F air temperature. There is very little ambient light underwater, so be sure to bring a bright primary light as well as backup light and personal marker light for each diver.
