[edit] Contradictions

The article right now gives contradictory information as to how many of these missiles were deployed. This is not surprising as sources often contradict each other on such matters. That's why when giving any numbers it is always useful to provide the reference from which they were obtained. My numbers were from reference listed below, i.e. The Kremlin's Nuclear Sword. So, where does the information "A single launch pad was operational at Baikonur and from six to eight were in operation at Plesetsk" come from? Balcer 06:05, 16 Jun 2005 (UTC)

I must admit I am not an expert on Russian missiles, but shorely the part in the article which states that the R7 was developed for A-bomb technology, and further states that the warhead has a yield of 2.9MT, this doesn't add up what A-bomb had a yiled this large, either the figures are wrong or the warhead was a H-bomb. —Preceding unsigned comment added by Yakacm (talk • contribs) 09:55, 29 October 2007 (UTC)

Yes, the warhead was thermonuclear, an H-bomb, not an A-bomb. —Preceding unsigned comment added by DonPMitchell (talk • contribs) 18:11, 14 May 2008 (UTC)

[edit] Wrong deployment time?

The article states that the missile was deployed from 1959. However, the article about Sputnik 1 states that it was launched by a R-7, in 1957. Is this deployment time supposed to include satellite launches? If so, the date should be changed.

Fact sequence is:

1. Development of R-7 was initiated in 1954 in OKB-1 of S.P.Korolev
2. First launches in May 1957
3. 04 Oct and 03 Nov 1957 first satellites were launched using R-7.
4. The first body of troops (formation?) of ICBMs has became the "Angara" object ("combat station" photo?) of 4 launchers under the command of colonel M.G.Grigoriev. The deployment of "Angara" was completed in fall 1958.
5. The first in the USSR combat/training launch of R-7 from the "Angara" station was performed in July 1959.

The article states that a nuclear warhead was launched on October 1957, but the only R-7 launch that month was Sputnik-1. Among the many problems with this article. When was the first actual successful launch and detonation of a thermonucelar warhead by R-7? DonPMitchell (talk) 15:03, 3 April 2008 (UTC)

[edit] Picture

Isn't the picture a Vostok?

That is correct. It is indeed a Vostok. Of course the Vostok is derived from the R-7 (as are the Voshod and the Soyuz), so the image ist not wholly incorrect. Still, I would strongly recommend placing a better image on the page.

By the way: The image itself is also incorrectly labeled as “R-7”.

[edit] this article is ridiculous

so many derogarating words and insinuations like failure, not viable etc, the bomber would detroy it or icbm.. dugh..... the person who wrote that is just jelauous of russian achievements..the r-7 did its job just fine, its not failiure its huge success... just be happy it had never been pressed in to the service..

I agree, in particular, section "Operational history" is not neutral by far. I've added {{POV-section}} tag due to this. Cmapm

[edit] Censored article: great shame.

The R-7 is based on the german cluster design by Ing. Goetrupp, yet there isn't a single word on it in the article. Most of the rocket (layout, engine chambers, turbopumps, etc.) was designed by superior german engineers taken POW by the soviets. The russian missile programme was just as nazi-based as the US was with Wernher von Braun! 82.131.210.162 09:29, 4 October 2007 (UTC)

That's not at all true. That is a myth created recently by some German authors. The Russians used Germans to build a replica of the V-2 (which they called the R-1) and then sent them home in the late 1940s. Goetrupp was a radio engineer, he never designed rockets or rocket engines. The R-7's multi-stage design was based on detailed mathematical analysis of sequential and parallel stage designs made in the early 1950s at the Keldysh institute.

[edit] Specifications

I tried to remove some confusing and inaccurate inf. and to introduce inf. on modifications of R-7 rocket. I took specifications for 8K71PS from http://www.friends-partners.org/partners/mwade/lvs/spuk71ps.htm And specifications for 8A91 from http://www.friends-partners.org/partners/mwade/lvs/spuk8a91.htm I also corrected image caption after looking at this picture: Image:GPN-2002-000184.png Cmapm 17:43, 5 October 2007 (UTC)

I would beware of using wade's site as a final authorality on numbers. Some of Korolev's reports are contained in Raushenbakh's biography. Probably the best facts and figures are compiled in the book _Bolshoi Kosmichesky Klub_, recently compiled by Afanasiev. There are huge problems with the data in this wikipedia article, including some conversions to pound units based on British ton defintion (all "tons" are metric, 1000 kg).

[edit] Slight correction

The Stage-0 boosters for the Sputnik (first spec set) are listed as weighing 3.400 g(rams?). —Preceding unsigned comment added by 15.251.169.70 (talk) 00:37, 3 January 2008 (UTC)
