The Atlas V N22 is a crew rated variant of the Atlas V 422 - it sports two solid motor strap on boosters with two liquid fueled stages. A ULA Atlas V rocket will deliver the CST-100 Starliner spacecraft to a sub-orbital trajectory on its Orbital Flight Test (OFT) to the ISS. Boeing Starliner is placed atop a United Launch Alliance Atlas V rocket for first flight.

Atlas V Starliner - United Launch Alliance (ULA) Rocket Launch.

A ULA Atlas V rocket will send astronauts to the International Space Station (ISS) aboard The Boeing Company’s CST-100 Starliner capsule. The Atlas V Starliner builds on ULA’s solid history of success and incorporates new technologies designed for crew safety. Boeing cleared a crucial test on the way to returning the United States to human spaceflight launch capabilities by completing a successful pad abort test of the CST-100 Starliner.

Starliner will launch atop the Atlas V rocket from Space Launch Complex 41.

The United Launch Alliance Atlas V rocket, topped by the Boeing CST-100 Starliner spacecraft, stands on the launch pad at Space Launch Complex 41 at Florida’s Cape Canaveral Air Force Station during a wet dress rehearsal for Boeing’s Orbital Flight Test. It will be primarly used to support NASA's Commercial Crew program by taking the CST-100 to orbit. Dual Engine Centaur: For CST-100 Starliner missions, the Centaur upper stage will fly with two RL10A-4-2 engines, offering more thrust to accommodate the Starliner.It also helps shape the ascent trajectory to the Space Station.
