Soviet 57mm Aircraft cannons (N-57/OKB-16-57)

[robotnikman]

Very little info seems to exist on these weapons. If anyone has any additional info this weapon (or weapons, maybe they are different from each other?) that would be great, such as ammunition types used, rate of fire, etc. Below is the info I've compiled so far,


There seems to be a small handful or aircraft equipped with this weapon:
Tu-2RShR - Tu-2 with x1 Ns-57
Alekseyev I-215 - Early jet with 2x Ns-57 57mm guns
F1 MiG-9 - Prototype MiG-9 with x1 57mm N-57

The gun does not seem related to any of the other Soviet 57mm autocannons designs seen on ground based weapons and naval ships.

Pics I've found so far:

MiG-9 with 57mm

Spoiler: Tu-2RShR

There is some (accurate??) information on this weapon on a Russian website, accessible via https://www-airwar-ru.translate.goo...tr_sl=ru&_x_tr_tl=en&_x_tr_hl=en&_x_tr_pto=sc

Thanks! That confirms my suspicions, there were basically 2 different types of 57mm, a shorter one with only HE, and a longer one meant for tankbusting, with balistic characteristics similar to the ZiS-2 apparently.

That looks like a fairly short cartridge, so a cannon with a large HE charge.

Roughly speaking like the 30x113 NATO cartridge, as compared to 30x173.

Yep, though it looks like they are displaying the gun that was used on the TU-2, which apparently used a longer cartridge. Looks like they got the gun and ammo mixed up on the display



The cannon firing the shorter cartridge looks like this
