> five giant F-1 rocket engines—still the most powerful ever built
This is no longer the case. The SpaceX Starship has the Saturn V beat nowdays.
(Edit: I suppose the F-1 rocket engines still have the Raptor 2 engines beat, so the article is still correct. The Starship just has more engines than the Saturn V for more thrust)
SpaceX Starship is closer to the (failed) N1 Soviet Rocket which should have been the Saturn V competitor.
The N1, with its 30 NK-15 engine would have made it more powerful than the Saturn V and its 5 F-1 engine, but less powerful than SpaceX "Super Heavy" with its 33 Raptor engines.
Another similarity is that the NK-15 engine and the Raptor are both staged combustion engines, while the F-1 uses the simpler open cycle design. The F-1 is also much more powerful than both the Raptor and NK-15, that's why the Saturn V has only 5 of them.
F1 is still the winner in sea level thrust per engine (6770 kN vs 2660kN).
Raptor is more efficient (with higher sea level and vacuum specific impulse); it also has a much higher thrust density -- those 2660kN come from a nozzle only 1.3m in diameter, vs the F1's 3.7m diameter.
The higher thrust density and smaller size means that you can fit 33 raptors in a ~9m diameter circle and end up with a stage with double the thrust of the ~10m diameter Saturn V.
I noticed that when it said at the start:
