Most Powerful Rocket Engine

[Sbb1413]

When I search for "most powerful rocket engine" on Google, I found the answer is the F-1 engine, used on the Saturn V. It generates 6,770 kN of thrust.
However, in my opinion, the most powerful rocket engines are the Space Shuttle Solid Rocket Boosters. They generates 12,000 kN of thrust.

Edit: Google search now answers "RD-170" as the most powerful rocket engine.

August 2020 addendum: Google search answers F-1 as the most powerful rocket engine, again!

The Saturn V's F-1 engine is the most powerful LIQUID-FUELED engine in the world, while the Shuttle SRBs are the most powerful SOLID-FUELED engines.

In addition, the Falcon 9's Merlin 1D, Proton-K's RD-253, and the N1's NK-33 engines are quite powerful as well. They have the highest specific impulses, and thrust-to-weight ratios of any Earth-launchable engine in the world

AFAIR, the RD-170 was more power full than the F-1, but it used four small thrust chambers fed by the same turbopump, instead of one large thrust chamber.

RD-170 had 4 combustion chambers, RD-180 is as same as RD-170 but has 2 combustion chambers and RD-190 has one.

Hmm... I'd wager that the AJ-260 would be the most powerful rocket engine ever fired... and that was a half-length unit.

Most of you is roasted by Aerojet! Their upside down rocket very much high quality majestic power!
