Talk:Soyuz-7 (rocket family)

Merge with Sunkar
A recent article confirms that the Soyuz-5 project will go ahead, but now designates the Feniks project Sunkar with traditional Kerosene/LOX propulsion instead of the Methane/LOX envisioned for the Soyuz-5 architecture described here. I suggest merging the pages, taking the specs from Sunkar, and listing the former Soyuz-5 specs in the History section. — JFG talk 09:51, 17 August 2017 (UTC)


 * I am not sure it is a good idea to merge them as you suggested. The source you mention also states that the only thing in common with the original Soyuz-5 launcher design is the name. Basically they renamed the original Soyuz-5 to Soyuz-7 and the Soyuz-5 name given to the Sunkar launcher. My suggestion would be to rename this article to Soyuz-7 and mention the history of renaming of project, then also rename the Sunkar project to INCLUDE the Soyuz-5 name in it.

Support. Sunkar and Fenix were just preliminary names as Rogozin said. Official name is Soyuz-5. It's all the same. Elk Salmon (talk) 16:40, 5 October 2017 (UTC)
 * Incorrect assumption that this article is about the new Soyuz-5. The name is recycled as I mentioned above, this article is about the first (older) Soyuz-5 methane-fueled rocket which is now called Soyuz-7. The second (newer) Soyuz-5 kerosene-fueled rocket is completely different design . These are 2 different rockets that share the name and the projects. Sunkar/Feniks project encompasses the development and is not the name for a rocket, hence 2 different rockets came from same project. — Preceding unsigned comment added by Hammer5000 (talk • contribs) 11:28, 8 November 2017 (UTC)
 * Haven't been reading this article. Came from Sunkar discussion link. But ok then — rename Soyuz-5 -> Soyuz-7, Sunkar -> Soyuz-5. Though it's in early studies without any actual development plans. Elk Salmon (talk) 15:07, 11 November 2017 (UTC)

By 2019 the Soyuz-7 name seems to be used for a kerosene project, and the methalox rocket is just called RN SPG ('rocket LNG'?). - Rod57 (talk) 17:43, 15 July 2020 (UTC)

2020 information on a methalox Soyuz
says "On the first stage of the new carrier, it is planned to use Voronezh RD-0169, on the second-the same RD-0169, but with a high-altitude nozzle." - Rod57 (talk) 17:37, 15 July 2020 (UTC)

Merge discussion

 * Info: There is a discussion about a merger with Amur (launch vehicle) in the spaceflight portal. --mfb (talk) 02:35, 21 October 2020 (UTC)
 * The Russian-language version of Amur (launch vehicle) was merged to the Russian-language version of this article. – wbm1058 (talk) 23:25, 16 December 2020 (UTC)
 * The Russian-language version of this article appears to be titled Soyuz-7 (launch vehicle). – wbm1058 (talk) 23:42, 16 December 2020 (UTC)

In the sources, it actually lists Soyuz-5, not Amur, and Fenix is a name for Soyuz-5. Fredinno (talk) 07:20, 8 January 2021 (UTC)

I have merged Amur (launch vehicle) in Soyuz-7 (rocket family). Regards. Artvill (talk) 11:36, 5 September 2021 (UTC)
