in fact tested only n-37 + 2xb20 (prototype of yak-9ut) and ns-23 + 2xb20 (in serie), "bible for yak-fans" (i mean, А.Т.Степанец, it's our reality without any big modern reseaches in archives) talking us about only n-37...

other sources and info from old game, mainly, repeat or very, very questionable... or just wrong...

plus, just logic - new weapon (ns-23 and b-20)... and old , heavy ns-37? what for?

Please double check but I don't think the N-37 was available until 1946?

of course, start of serial production in 47, but here question about correctness for prototype of yak-9ut in game...

or n-37, or nothing (n-37 was "ready" and tested in 44-45, so, why not?)...

plus, we must remember what WW2 end in september 1945 (Japan crushed by great USSR-blitzkrieg etc), so, all questions about perfomances, weapons etc must be looked from this position too...


well, some info about n-37 (more, in something like "Пушки для боевых самолетов, Автор: А.Э. Нудельман") - В апреле 1944 г. был изготовлен первый экземпляр пушки Н-37, а в августе 1944 г. были завершены наземные государственные испытания патрона и пушки. Первые летные испытания проводились на Як-9Т и Як-9УТ в марте 1945 г. Пушка была установлена в моторе. В дальнейшем летные испытания проводились на МиГ-9.


some info about first aut'45-tests of yak-9 with vk-107a (it's yak-9u, "эталон 1945г.") with 2xb-20 + b-20 (b-20 can be changed to ns-23, n-37)...

and -

23 марта 1947 г. в НИИ ВВС на контрольные испытания поступил в третий раз самолет Як-9П N01-04, на котором были произведены следующие изменения: ... вместо мотор-пушки ШВАК с боезапасом 120 снарядов предусмотрена возможность установки одной из четырех мотор-пушек: Б-20М, НС-23, Н-37, Н-45 с боезапасом соответственно 115, 75, 28 и 25 снарядов (пушки Н-37 и Н-45 в то время были еще опытными).

and other words about n-37 in yak-9p tests after end of war...

N-45 was another optional armament addition but I also think that was post war as well. I'm not sure about that.

b-20 and n-45 only "what if", of course... and, maybe, mainly for yak-9p vk-107a...

The focus in my mind was definitely on aircraft and armament types that exists during the war and saw use.

agree, but sometimes, "easy" (i mean, historically correct + easy to do for game, by ingame tools too) things may be include, why not?

I didn't realize you were talking about the earlier Yak-9P. Is it based on the early Yak-9U prototype with VK-105PF? Didn't some of these early Yak-9U's make the front line? That may be the type that could be done rather than the P model?

first yak-9p was yak-9 (yak-9 1942 in game) with vk-105pf and second shvak instead UBS (1 shvak with 120-140 rounds + second shvak with 165 rounds), he was tested in spring of 43 and was recommended for production...

and...

about name yak-9p for yak-9p with vk-105pf -

Як-9П (пушечный) с двигателем М-105ПФ...

about name yak-9p for yak-9p with vk-107a -

Як-9П ВК-107А... Буква "П" в обозначении самолета не несет смысловой нагрузки, а является заводским обозначением очередной модификации, подобно Як-9Л (Як-9Б), Як-9К) (Як-9ДД), что часто практиковалось на заводе N153. В ряде случаев присвоение наименований производилась постановлением ГКО.

I understand the interest in the unique armament configuration. What visual external differences existed to fit the second ShVAK? Any pictures? I'm curious if nothing else.

how say to us all sources - little external differences (some differences of gun port for shvak, and maybe without armor glass because it was prototype or because no armor glasses at the moment), similar perfomance (only little unstability on low speed when firing and +10-15 kg of weight to mass)...

well, you can read all this self anytime (1 photo here) - here or here...
