The 2021-12-07 launch was the 90th flight of the Atlas 5 and the rocket’s longest mission, requiring three RL10C-1 upper-stage engine burns.
United Launch Alliance planned to fly the new Atlas 5 features to accumulate flight experience before transitioning them to its future Vulcan Centaur rocket, which will have a 5.4-meter payload fairing.
The Atlas 5 that launched STP-3 debuted an advanced GPS navigation system for the Centaur upper stage intended to improve the accuracy of orbit insertions.
A United Launch Alliance Atlas 5 rocket launched the Space Test Program-3 (STP-3) mission for the U.S. Space Force on 2021-12-07.
STP-3 flew to geosynchronous Earth orbit on an Atlas 5 551 configured with five strap-on solid rocket boosters.
The Atlas V launched STP-3 in the 551 configuration that included a 5.4-meter payload fairing and stood 59.7 m (59.7 m) tall.
The In-Flight Power System on the STP-3 Atlas V ensures the spacecraft have fully charged batteries when deployed into geosynchronous orbit.
The payload fairing for the Atlas V rocket on the STP-3 mission was produced at the RUAG Space site in Decatur, Alabama.
The 2021-12-06 Atlas V launch will be the first flight of a RUAG Space payload fairing fully produced in the USA.
A United Launch Alliance Atlas V rocket will launch the Space Test Program-3 mission for the U.S. Space Force Space Systems Command from Cape Canaveral, Florida.
A United Launch Alliance Atlas V rocket is scheduled to launch a U.S. defense satellite into space on 2021-12-06.
Vulcan is slated to replace United Launch Alliance’s Atlas V rocket because the Department of Defense cannot procure Atlas V beyond 2022 due to its use of Russian-built RD-180 engines.
Booster propulsion on the Atlas V is provided by the RD-180 engine system, a single engine with two thrust chambers that burns RP-1 and liquid oxygen and delivers 390,180 kg (3.83 mega-Newtons) of thrust at sea level.
Five solid rocket boosters generate an additional 168,532 kg (1.6 mega-Newtons) of thrust at liftoff for the Atlas V configuration used on STP-3.
A United Launch Alliance Atlas V 551 rocket was scheduled to launch the Space Test Program-3 (STP-3) mission for the U.S. Space Force’s Space Systems Command on 2021-11-09.
The STP-3 integrated payload stack was mated with United Launch Alliance’s Atlas V 551 launch vehicle at Cape Canaveral Space Force Station on 2021-11-22.
The Atlas V for STP-3 is equipped with a new In-Flight Power System that supplies power to the satellites’ batteries during the rocket’s long-duration ascent of more than seven hours.
Amazon signed a launch agreement with United Launch Alliance to deploy Project Kuiper satellites aboard Atlas 5 rockets.
Amazon ordered nine Atlas V rockets from United Launch Alliance in April to help deploy the Project Kuiper network.
The STP-3 mission was previously scheduled to launch 2021-06-23 from Cape Canaveral but was delayed to investigate an issue in the Atlas 5’s RL-10 upper stage engine.
