Buckley SFB

Buckley SFB's host unit Space Base Delta 2 (SBD2) falls under the direction of the United States Space Force.

SBD2 is responsible for day-to-day support to the operational mission of Space Delta 4 (DEL 4) Missile Warning Delta. Buckley SFB and DEL 4 directly support Combatant Commands across the globe.

Buckley SFB is home to 107 tenant units including Space DELTA 4 Missile Warning, the 140th Air Wing, Colorado Air National Guard (COANG), the Navy Reserve Center Denver, the Aerospace Data Facility-Colorado, the Army Aviation Support Facility and the Air Reserve Personnel Center. These are also known as the "Big Six" mission partners at Buckley.

Buckley SFB truly represents a joint, Total Force and coalition base. This includes 3,500 active duty members from every service, 4,000 National Guard personnel and Reservists, four commonwealth international partners, 2,400 civilians, 2,500 contractors, 96,000 retirees and approximately 40,000 veterans and dependents. The base contributes over $1 billion annually to the local economy.

The Defense Switched Network (DSN) is a primary information transfer network for the Defense Information System Network (DISN) of the United State Department of Defense. The DSN provides the worldwide non-secure voice, secure-voice, data, facsimile and video teleconferencing services for DoD Command and Control (C2) elements, their supporting activities engaged in logistics, personnel, engineering, and intelligence as well as other Federal agencies.

In 1982, the DSN was designated by the Office of the Secretary of Defense (OSD) and Joint Chiefs of Staff (JCS) as the provider of long-distance communications service for the DoD.  DSN replaced the older Autovon system.

In order to place a call using DSN, the caller must be using a military telephone on an installation. When dialing a DSN number from a United States installation to another United States installation, it is unnecessary to dial the DSN 312 area code.  When dialing a DSN number to/from overseas location, the DSN area code must be included. Cell phones cannot dial DSN numbers.
