Merge with Sunkar

A recent article[1] 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)[reply]

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 [2] 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. [3] Elk Salmon (talk) 16:40, 5 October 2017 (UTC)[reply]

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[4]. The second (newer) Soyuz-5 kerosene-fueled rocket is completely different design [5]. 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)[reply]

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)[reply]

By 2019 [6] 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)[reply]

2020 information on a methalox Soyuz

[7] 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)[reply]
