The RS-25 engine controller that has been tested will be used for the NASA space launch system (SLS). The SLS deep space rocket will be launched by four RS-25 engines at the same time, generating 2 million pounds of thrust. With a pair of solid rocket boosters, it will generate more than 8 million pounds of thrust.

The original SLS RS-25 engine became the main engine of the shuttle, which was transformed to provide the initial power needed for a larger SLS rocket. According to NASA, the key part of the modification is the new flight controller, which is the core of RS-25. It helps the engine communicate with the SLS rocket and accurately control the diagnosis of engine operation and internal condition.
