There is a lot of debate about why the Soviets chose this approach, but for me its a combination of three reasons:-
a) Previous Soviet Rockets were also based on the "many small engines" approach - they worked fine. (Even if it was not the most efficient approach)
b) A key reason the the N-1 ended up with 30 NK-33 engines instead of something more manageable was political infighting. The Soviet chief engine disigner Glushko had an intense argument over fuel choice with the N1 designer Korolov and ended up taking experience to the Soviet military with the UK-500 and 700 boosters. That left Korolov with no engine designer and in the end the N-1 had it's engines designed from existing templates.
c) At the time there were real doubts over the feasibility of combistion stability in engines with large injector surfaces. (Ie - large engines). It took Rocketdyne many, many tests to get the F-1 to work. The Soviets felt that developing these large engines was simply too risky (and expensive), despite the obvious efficiency gains.

The NK-15 was actually used on the N-1. The NK-33 are the modified NK-15 engines sold to Kistler. The NK-15 is based off the design for the NK-9.
The engines in the R-7, the RD-107/108, were single turbopumps (one for fuel and one for oxidizer) driving four combustion chambers. The reason for four combustion chambers was to deal with acoustic problems inside the chamber. The F-1 had similar acoustic problems, but they were solved with baffles inside the chamber. The RD-170/171/180 are also multiple chambers driven by single fuel and oxidizer turbopumps.
Glushko's bureau did the N2O4-hydrazine engines for the UR-500 (Proton). The UR-700 was never built.

The same basic considerations are why the jet engines used in the very successful Su-27 class fighters are more fuel-thirsty for the same thrust as an F-15 class fighter (the two are roughly equivalent). The hotter you can get, the more expansion you can get. If you don't have the expansion, the only way to get the same thrust is to pour more fuel into the nozzle. The Russian designers are confident that their newest engines for the Su-30 class follow-ons to the Su-27 are every bit as good as current Western engines -- but they have not had the money to actually build the things.
There is also, of course, the Russian tendency to improve existing designs rather than embark upon all-new designs. For example, the next-generation Russian air superiority fighter, the Su-34/Su-35, is basically an Su-27 improved with the latest in materials to decrease weight, increase strength, and improve payload and maneuverability (not to mention better engines). The Su-34/Su-35 aren't going to be built because Russia cannot afford them, but show what Russian designers prefer to do rather than embark upon all-new aircraft like the U.S. designers like to do. The N-1 engines were similar in design to other engines used by the Soviets, and thus preferable, in the eyes of Russian designers, to all-new (risky) engine designs.

To clarify, the name "Saturn V" refers to an assembly of several stages: the S-IC, S-II, and S-IVB. The first and biggest stage, the S-IC, was a pure LOX-kerosene stage. Its F-1 engines (1.5 million pounds thrust each) burned kerosene, only the upper stages burned hydrogen.
This makes a lot of sense -- "efficiency" (in terms of Isp) is only one figure of merit in rocket engines. It's more relevant when the engine no longer has to lift the mass of the vehicle against gravity. For lifting power (as with a first stage), you care about thrust, which is proportional to the mass of the exhaust products (and thus the mass of the fuel). Hydrogen is just too light to generate useful thrust except at very high exhaust velocities, which means very high engine pressures, which means heavy engines, etc, etc. (Also, because of LH2's low density, you need bigger fuel tanks, which weigh more, etc, etc.)
Case in point, the three Shuttle SSMEs together (which burn LO2/LH2) have barely more thrust than a single F-1 engine, and run at a much higher chamber pressure.
There's a reason the Shuttle uses those god-awful, low Isp solid boosters -- to create enough thrust to get off the pad!

The decline of NASA started with the moon landings. After that, NASA could not justify itself to the public, because the Russians had been beaten, and the race was over.
Thus NASA had to become more "cost effective" (the moon landing was done by crash-program techniques such as paying for several alternatives and selecting the best one after it is developed). So NASA sold the concept of the Space Shuttle as an inexpensive way to get mass into orbit. In order to justify it, they also had to make it the launcher for military payloads, so they connived to force the military into fitting their payloads into the shuttle, and defunding their own launch capabilities.
The problem with the shuttle is that is far more expensive that projected (big surprise). A primary reasonis that it is man-rated, which greatly adds to cost.
In order to continue to justify their existence, NASA needed a mission. The environmental movement came along just in time for them - they could devote their resources to studying the environment, and get government bucks to put up space-borne systems to do that. But, to justify continuing the shuttle, they needed a big, manned project... and thus was born the International Space Station.
But the ISS caused NASA to put almost all of their money into one bucket, leaving little else for other research. And ISS is not a particularly good way of doing most things - because most things don't need a manned space station, they can get by with a much less expensive non-manned launch.
Furthermore, NASA did its best to quash competition in the space launch business - again to keep justifying the money for the shuttle. After the Challenger disaster and subsequent grounding, NASA had to allow the military to use its own launchers for critical payloads, but they still have not been nice to little guys.
As a result, we have a small fleet of aging shuttles, that launch at an average cost of $500,000 per mission, at a mission rate a fraction of what they were supposed to be able to do.
One solution is not to give more money to NASA. It is to create incentives for private enterprise to get into the game.
As an example, what would happen if there was a $30 billion prize to the first company to land humans on mars and bring them back successfully? Hopefully, it would lead to some pretty innovative work.
Another approach that might work is to stimulate the public with some historic vision (like Kennedy did with the moon landing) and get public support for a truly imaginative leap.

That depends if the companies in question have the capital in order to do all the R&D and if the management decides that rate of return on that capital is sufficient for them to invest in it. What NASA initially gets may not be commericially viable, but in the process much is learned and with a few iterations it does become viable. Many companies don't want to or can't wait a couple iterations for something to become viable. The standard answer that many have is that for every $1 spent on NASA, $7 is generated due to commercial spinoffs. It's the same reason for any sort of research funded by the Govt. Or do you think the DARPA guys should have just sat back and took the position of "Well, if interconnecting diverse computers over a large geographical distance with a common protocol has genuine commercial potential, let's just wait until the vendors develop something on their own and drop it on our doorstep."?

Eventually, Von Braun was allowed to put the first American satellite (Explorer 1) in orbit with his Jupiter C rocket.

This worked well - up to a point, as they discovered with the N1. Even today, most Russian space boosters are variations on the old Vostok booster that put Sputnik and Gagarin into orbit in the early 60's. The US tends to invent whole new technologies but even today tried-and-true designs from the early part of the Cold War are still in widespread use: American Atlas and Titan boosters originated as missiles and the Delta booster has been around forever.

As for the explosions that they had during launch. Apparently this was a part of test program with each test ironing out the bugs in the system. For example one of the launches was wrecked by debris getting into the engines.
Apparently they reckoned that they would need 11 launches before they got everything ironed out.
I call these guys real engineers, if you have limitless funds like NASA did in those days you could do almost anything. But to do things on a tight budget and limited resources takes brains

Now that you've read all the posts about how the Russian space program is done, read this Wired article [wired.com] (http://www.wired.com/wired/archive/9.12/rd-180.ht ml) that describes how US companies are launching their payloads using Russian propulsion.
Here's a quote: "They build the thing and test the shit out of it. This engine cost $10 million and produces almost 1 million pounds of thrust. You can't do that with an American-made engine."
magnetism and rockets (Score:2, Funny)
Clearly, the Soviet space program was hamstrung by the fact that during the cold war, magnetic north was in the territory of the west. Without free access to the actual magnetic North Pole (though Lech Walesa was a pretty magnetic Pole), they obviously had a hard time navigating, as their most sophisticated navigational equipment (besides the sextant) was a souvenir compass obtained from an East German high school science fair.
Too bad they don't have the budget to pursue the moon again now that magnetic north will actually be in their own territory. They would have a distinct advantage over Nasa if they could make Nasa pay for access to magnetic north, maybe on a subscription basis or using micropayments.
All this rocket stuff is so confusing!
Yet another massive failure of central planning (Score:4, Interesting)
The Ghost of the Executed Engineer is a great history as told by a Soviet engineer of a number of different massive engineering failures that occurred under central planning. I.E The Building of the white sea canal in which 200,000 people died and the resulting canal was much less usefull than the railroad that was proposed by engineers before the commencement of construction that would have cost less to build in terms of lives and capital.
BTW, the greatest technological failure of all time was a series of dam collapes in China in 1975 that caused the deaths of more than 85,000 people and as many as 200,000 if you count the resulting disease epidemics set off.. Story here [sjsu.edu]. Which is why everyone has been so warry of the Three Gorges Dam project.

Like all the times they beat us in the space race. Satelites. Probes. Rovers. Etc.
Ask the Nazis what they thought of Soviet central planning. It did not seem to matter that the Red Army lost personnel and material in quantities that would have decimated any other form of government. The will to fight came from a very stubborn center. The /entire/ /country/ was doing nothing but producing weapons scientists, weapons factories, and soldiers. After Germany lost their first campaign, it was all over. The Soviets produced effective tanks and planes with single-minded dedication in quantities Germany could never hope to match.
Centralized planning can be very good for a small number of projects that need to be rushed.

Well, not in 1969. I note from your links that the successful ones were 1 in 1966, 2 in 1970, 1 in 1973, 1 in 1976.
I just didn't feel like posting the complete list, which you can see in the original link I provided.
http://www.russianspaceweb.com/spacecraft_planetar y_lunar.html [russianspaceweb.com]
has a comprehensive list.
out of 59 launches from 1958 to 1976, there were apparently 18 successful missions.
1969 was a really bad year.
over all, looks like about half (?) exploded or never left earth orbit, etc. or otherwise had other problems. Since the original post nattered about a mission about the time of the first American Moon landing (1969) quoting the stats from 1969 seemed relevant.

Having built simple and effective rocket engines they tried to bundle them together to make a huge rocket.
That created complexity.
The Americans built more complex gimballed rocket engines, which allowed them to build a simpler overall rocket (Saturn V) with fewer engines.
So the russians created complexity by combining many simple components
Where the americans had a simpler design of more complex components.
I think the moral is that elegance and efficiency of design is important throughout any significant engineering project.
