VANDENBERG, California Air Force Base – U.S. spy satellite was launched into orbit from California.

The powerful Delta 4 Heavy rocket carrying the National Reconnaissance Office satellite exploded from Vandenberg Air Force Base at 11:10 am Pacific time Saturday.

As is customary with secret content, United Launch Alliance webcast takes off only through periods when aerodynamic fairings that include payloads are discarded.

The mission details, dubbed NROL-71, were not released.

The launch has been repeatedly postponed since late last year for reasons including hydrogen leakage, strong winds and problems with ground communication equipment.

The National Surveillance Office is responsible for U.S. intelligence satellites.

United Launch Alliance is a joint venture of Lockheed Martin and Boeing.

Delta 4 Heavy is 233 feet (71 meters) high.
