Default F-1 engine - first launch

The bottom of this page http://www.astronautix.com/engines/f1.htm says
"first launch 1959". Wasn't this only a static test firing? The
first launch was the Saturn V with Apollo 4, right?

Sounds right to me.

According to 'Stages to Saturn' (the official NASA history of the
development of the Saturn launch vehicles) the first test-firing of an F-1
was March 1959 - it "demonstrated stable combustion for 200 milliseconds."
The Apollo Spacecraft Chronology sets it at 6 March.

200 milliseconds? And what happened then, unstable combustion?

Alan Lawrie's "Saturn: The Complete Manufacturing and Test Records",
(2005, Apogee Books), says the 06 March test was only of the 'thrust
chamber'. The first 'engine thrust chamber main-stage test' was 10 Feb
1961, and a 'complete F-1 prototype engine' test was 11 Jul 1961 (both
at EAFB). The first 'complete system firing' was 16 Aug 1961, and the
first 'rated thrust and duration test' lasted 2m 30s on 26 May 1962
(also EAFB).

To clarify; I was in agreement with the poster Jan Philips, not the
Astronautix article.

OTOH it's far more informative when I'm presumed wrong and am corrected.
So for the sake of this thread pretend I'm in agreement with the
Astronautix article instead. :-)

Yes, I had to read it carefully to understand which side "sounded
right".

....Here's a test of just how badly Google has let the old DejaNews archives deteriorate just over the past two years: do a search on "F-1" and "Combustable Instability", or just "Instability", and narrow your search between 1998 and 2004 - the former is the earliest I can recall the topic of how they resolved the problem showing up around here, the latter was from a thread involving the resurrection of the F-1 for a possible booster replacement for the then-unnamed Shuttle replacement. In any case, there's been at least 8-10 threads about this over the 15+ years this group has been around, and all of them were pretty thick in the details.
