1/100 Space Shuttle Main Engines

The RS-25 rocket engine (most commonly known as the Space Shuttle Main Engine or SSME, is one of the most efficient and powerful liquid oxygen/hydrogen rocket engines ever produced. It is also one of the most complex. While the larger Solid Rocket Boosters (SRBs) provided most of the shuttle’s thrust at liftoff, most of the Orbiter’s speed to get to orbit was provided by the 3 SSMEs. Fueled by the large External Tank, each SSME provides around 500,000 pounds (2 megaNewtons) of thrust. 4 of these same engines will be used on NASA’s new Space Launch System (SLS) rocket.
