Model RS-25 Engine - Space Launch System - Datasheet

The Boeing 747-400 is powered by four large turbofan jet engines. Likewise, the Space Launch System (SLS) core stage is powered by four RS-25 engines. The thrust provided by the SLS RS-25 engines could keep eight 747s aloft. The RS-25 is so powerful that if it were generating electricity instead of propelling rockets into space, it could power 846,591 miles of residential street lights. That’s a street long enough to go to the moon and back, then circle the earth 15 times.
