Top 10 Rocket Engines with the Highest Thrust in the World, Global Ranking of Rocket Engine Thrust, Top 10 Rocket Engines in the World.
Top 10 rocket engines with the highest thrust, also known as the rocket engines with the most powerful thrust. Thrust is a crucial factor in determining the performance and capabilities of a rocket, as it measures the force with which the engine expels propellant and propels the vehicle forward.
1. F-1 (Saturn V):
The F-1 engine was developed by NASA for the Saturn V rocket, which was used during the Apollo program to send astronauts to the Moon. It remains one of the most powerful rocket engines ever built, with a thrust of approximately 15 million pounds.
Developed in Russia, the RD-170 is a liquid-fueled rocket engine known for its impressive thrust of around 1,670,000 pounds. It has been utilized in various Russian rockets, including the Zenit and Energia launch vehicles.
3. SSME (Space Shuttle Main Engine):
The Space Shuttle Main Engine was used in NASA’s Space Shuttle program. Each Space Shuttle had three SSMEs, and collectively they provided a total thrust of approximately 1,491,000 pounds.
4. F-1B (Space Launch System):
The F-1B engine is an upgraded version of the original F-1 engine and is part of NASA’s Space Launch System (SLS), intended for future deep space missions. It is expected to deliver a thrust of about 18 million pounds, making it one of the most powerful rocket engines in development.
5. RS-25 (Space Launch System):
Also a part of NASA’s SLS program, the RS-25 engine (formerly known as the Space Shuttle Main Engine) is being adapted for use on the SLS. Each RS-25 engine produces a thrust of approximately 1,540,000 pounds.
6. F-2 (H-IIA):
Developed by the Japan Aerospace Exploration Agency (JAXA), the F-2 engine powers the H-IIA rocket. It provides a thrust of about 1,190,000 pounds and is instrumental in Japan’s space missions.
7. Merlin 1D (Falcon 9):
The Merlin 1D engine is used in SpaceX’s Falcon 9 rocket, contributing to its success in launching both cargo and crewed missions to space. Each Merlin 1D engine generates around 1,210,000 pounds of thrust.
This Russian engine, with a thrust of approximately 1,015,000 pounds, was initially developed for the Soviet lunar program. It was later revived for use in commercial rockets like the Antares launch vehicle.
9. RS-68A (Delta IV):
Manufactured by the United Launch Alliance (ULA), the RS-68A engine is used in the Delta IV rocket family. It has a thrust of about 705,000 pounds and is designed for reliability and cost-effectiveness.
10. RD-180 (Atlas V):
Developed in Russia, the RD-180 engine powers the first stage of the Atlas V rocket, which is also used by ULA. It produces a thrust of around 860,000 pounds.
Please note that rocket technology is continuously evolving, the suitability of these engines depends on specific mission requirements and objectives, and factors such as fuel efficiency, reliability, and cost-effectiveness are also crucial in rocket engine design and selection.
