So I have just played the campaign of a certain game, and a mission involves shooting down a Soyuz LV. The problem is that the mission is supposed to take place in 1963, while I was under the impression that Soyuz first flew in 1966. Would it really be the Soyuz LV, or would it have more than likely be the Voskhod LV?
There were small differences between the Soyuz and Voskhod launchers, mostly involving the engines. The Soyuz 3rd stage used an RD-110 engine, same as the current Soyuz-U/FG launchers, whereas Voskhod used the older RD-107 engine. Voskhod could not have launched a Soyuz spacecraft.
The engine on the upper stage was the RD-0108, a Kosberg design bureau engine. The RD-107 was (and is) used on the four boosters which constitute the first stage of Soyuz. The RD-108 is used on the core stage of Soyuz (second stage in Russian terminology). The RD-107 and RD-108 are from Glushko's design bureau.

Opps, the Voshkod 3rd stage engine was RD-0107, and the Soyuz 3rd stage was and is RD-0110.
RD-0108 8D715P was used on the piloted Voskhod launchers; and was also fitted on the first six manufactured Molniya-M third stage.

Soyuz 4/5 question:
Given that the hatch on the Soyuz orbital module seems to be bolted on by technicians on the ground, how did the cosmonauts open the hatch for their EVA? Was the hatch specially modified for the EVA, or was the hatch for all of the early Soyuzes designed for EVAs?

Yep, Voskhod used RD-0108 for the final stage, and Soyuz used and uses RD-0110 for all variants prior to Soyuz-2.
On the KBKhA website it lists just 51 x RD-0107 and 20 x RD-0108; though I'm not sure if that's just the successful flights?
On Vovan’s post on the Novosti Kosmonavtiki forum is an interesting list of differences, between 11A57 Voskhod, 11A511 Soyuz and the 11A511U Soyuz-U. One major difference between Voskhod and Soyuz-U is the adoption of the 11S59 lower 1st and 2nd stages; the 11S59 features a central Blok-A with the control system reduced in height.
Did the Molnija-M ever adopt the 11S59? Timothy Varfolomeyev articles in B.I.S. Spaceflight magazine suggest so… but reading the article again it sounds like it adopted the Soyuz 11A511 core first.
Thanks to Mr. Lissov, failures of RD-0107 engines

Soyuz 4/5 question:
[SNIP]
Shatalov opened the Soyuz-4 orbital module hatch; from inside the descent module.
http://www.novosti-kosmonavtiki.ru/content/numbers/231/36.shtml
[SNIP]
Yes, but I don't believe that the hatch can be opened from the inside anymore, which begs the question as to whether the Soyuz 4/5 hatches were specially designed, or whether Soyuz design has since been changed.
From the 2010 NASA "Worldwide Spacecraft Crew Hatch History" document, NASA/TP–2010–216131. (
http://ston.jsc.nasa.gov/collections/TRS/_techrep/TP-2010-216131.pdf)
The OM also has a docking/transfer hatch and a crew entry/exit hatch that serves as an EVA hatch. Both crew hatches are inward opening and pressure sealed.
So I guess it still can be done, which makes sense if you have some emergency that might be fixable during EVA, quite some time after undocking from ISS, or want to fix a docking mechanism issue by EVA before docking.

Nevertheless, I don't believe that current generation Soyuz have an OM hatch that may be opened by the crew in orbit, it appears to be bolted on.

The outside may well be bolted on, but the hatch is inward opening, so that's no issue. Perhaps someone can provide definitive proof.

In NK n°334 (2010-11), there is a list of all launches of the early warning program, but Cosmos 1940 is not in the list.
Is it a mistake, or is there a point that I didn't understand ?

It would not help much, if you don't have EVA suits on board. AFAIK Soyuz spacecraft do not routinely carry Orlan suits on board.

True, but still having the option to employ Orlan suits on specific flights can prove beneficial.

I was under the impression the Sokol suits could be used for a contingecy short EVA (though I may be having the wrong recollection)

I am considering a possible EVA from inside a Soyuz as part of an ISS contingency.
Although I haven't seen any evidence that the OM hatch can be opened by the crew from inside, and I don't think that an Orlan suit can fit through the hatch; however, I have a dim recollection that the OM has some primitive Orlan servicing systems, which makes little sense.

In 2006, an unidentified Soyuz SA was put on display on the USS Hornet, in Alameda, California.
Now, it seems that this capsule has moved to Chabot Space and Science Center in Oakland.
Someone can confirm this is the same capsule ?
Do you know which spacecraft it is ?
Thanks !

Do you know how to translate "построитель местной вертикали"?
It's a device which finds Earth surface normal vector (by detecting Earth limb in a few directions).
