The Air Force has launched a satellite that is classified for national security reasons, The Associated Press reported.

The top-secret mission was taken into the sky by the unmanned Atlas V rocket, which had a successful blastoff from Cape Canaveral Air Force Station Thursday morning. Due to the satellite's classified nature, no details about its mission and purpose have been disclosed.

The satellite came from the National Reconnaissance Office, which designs, builds and flies national intelligence satellites, while the rocket was provided by the United Launch Alliance, according to the AP. Launch Control said the mission was a success.

Preparation for launching the rocket started about two hours before, with crews loading liquid oxygen into the first two stages and liquid hydrogen into the upper stage, Florida Today reported.

"The Atlas booster burns Rocket Propellant-1, a highly refined kerosene, and is powered by the Russian-made RD-180 engine, with no strap-on solid rocket motors in use for this mission," according to Florida Today.

The United Launch Alliance rocket comprises 19 stories and was brought to the Launch Complex 41 pad on Tuesday morning.

The launch was webcast live on Thursday morning but ended a few minutes into the flight because of the top-secret nature of the satellite mission.
