1. The operational unit at Cheyenne Mountain Air Station (CMAS) is commonly referred to as the "Cheyenne Mountain Operations Center" or "CMOC".

2. CMOC contains elements from NORAD, USSPACECOM, and AFSPC.

3. The acronym "NORAD" represents "North American Aerospace Defense Command".

4. The acronym "USSPACECOM" represents "United States Space Command".

5. The acronym "AFSPC" represents "Air Force Space Command ".

6. The Cheyenne Mountain Complex is about 7,100 feet above sea level at its highest point.

7. Excavation and construction for the complex began on May 25, 1961 and took a total of four years and seven months to complete. Initial Operational Capability or "IOC" was achieved on December 15, 1965. The Cheyenne Mountain Complex became completely operational on January 1, 1966.

8. 1.5 million pounds of dynamite were used to excavate approximately 693,000 tons of solid granite.

9. Today we use 115,000 rock bolts to reinforce the tunnel structure. Rock bolts run from 6 to 32 feet in length and function like molly bolts. Altogether, the rock bolts give the mountain the illusion that there is someone inside pushing outward on the walls. We thereby prevent implosion or cave-in.

10. The project was completed at a cost of 142 million US dollars back in 1965. According to a recent study, duplicating this facility today with all of its missions would cost about 18 billion US dollars.

11. The actual operations complex is a series of 15 buildings, 11 of which are three stories tall. Each building has its own tunnel and functions independently of the remaining structures.

12. The entire operations complex is mounted on a total of 1,319 springs, each weighing 1,000 pounds. They allow the complex to sway up to 12 inches horizontally in any direction. This insulates the complex in case there’s an earthquake or nuclear explosion.

13. The complex operates on a three-level power system. The primary source is commercial (the same as you use in your home), the secondary is a series of six 2,800 horsepower Enterprise (in-line eight) diesel engines, and the final is a series of interconnected batteries (equivalent to about 1,200 automobile batteries) which we refer to as the "uninterruptable power system (UPS)".

14. There are no furnaces in the entire complex. All heating is accomplished by removing the excess heat from computers and distributing it wherever it’s needed.

15. Approximately 1,450 people work at the Cheyenne Mountain Complex. Nearly 2/3 of these people work for AFSPC, approximately 250 are contractors/civilian employees and 246 are NORAD/USSPACECOM personnel that work directly for the Commander of CMOC. The personnel breakdown of CMOC by service is:

a. 19 or 8% Canadian Air Force

b. 145 or 59% US Air Force

c. 21 or 9% US Army

d. 38 or 15% US Navy

e. 12 or 5% US Marines

f. 11 or 4% civilian

16. The following are some of the workcenters contributing to CMOC’s functional mission:

17. The annual CMOC budget is approximately 175 million US dollars.

18. Cheyenne Mountain tours began during February 1967. No tours were conducted from 1980 through 1984 (inclusive) due to operational concerns. Tours were reinitiated in 1985.

19. The Cheyenne Mountain Complex normally conducts approximately 900 tours for over 22,000 people each year.
