HUNTSVILLE, Ala. — A United Start Alliance Atlas 5 rocket on Thursday launched the fifth Innovative Particularly Substantial Frequency (AEHF-five) communications satellite for the U.S. Air Pressure Space and Missile Systems Center. The Atlas 5 in the 551 configuration with five sound rocket boosters lifted off at six: 13 AM EST from Area Start Intricate-41 from Cape Canaveral Air Force Station, Florida.

Approximately five several hours, 40 minutes just after start, AEHF-5 separated and was deployed into room.

AEHF satellites provide secure, jam-evidence connectivity for U.S. nationwide leadership and deployed armed forces forces. Atlas V rockets correctly launched the to start with four AEHF satellites in 2010, 2012, 2013 and 2018.

The AEHF-5 launch marks the 80th Atlas five mission given that the inaugural launch in 2002 and the 10th in the 551 configuration with the Centaur higher stage and a 5-meter diameter payload fairing.

The 6,500 kg. AEHF-five completes a geostationary ring of 5 satellites offering global protection for the United States and worldwide partners Canada, the Netherlands and the United Kingdom.

The Atlas five rocket’s Centaur upper phase finished very first burn off at six: 25 AM. At 6: 29 AM launch data confirmed that the initial burn off by Centaur inserted the rocket into the goal orbit as prepared. The next primary motor cutoff was verified for Centaur at six: 42 AM, finishing the following step toward the specific orbit to deploy AEHF-five. The rocket then started a 5-hour coastline absent from Earth to get to the good point in area for the third melt away by the upper stage.

Thursday’s start was the 251st flight of the hydrogen-fueled Centaur. For this mission, it carried an experimental cubesat as a rideshare payload.
