Hi, I want to ask about the firing accuracy of 2A38M gun. It is twin barrel gun and 2 barrels are very closed so when firing, do the ballistic of projectiles be effected by shock waves from the other side barrel? Thank you.
First of all each twin barrel gun does not fire both barrels at the same time... the firing of one ejects the empty shell and loads a fresh round in the other barrel and then the round is fired to cycle the other barrel...
The accuracy required is not as high as you actually might think.
A rifle is not used for small fast moving targets... for such targets a shotgun is generally used because between the time you fire the shot and when the projectiles impact the target area the target could have sped up, or slowed down, or turned left or right etc etc.
That means it is actually better to have a scatter of projectiles around the point of aim so that if the target performs a manouver after the rounds are fired (when changes to the aim are meaningless) and when the rounds arrive on target.
The main reason they are looking at 57mm shells is because even with a fairly large number of shots fired a small target can still fly through the rounds at range.
Airburst round that explode when they get to the distance to the target on the other hand greatly increase the chance of hits and with small targets being rather more fragile those hits will be more effective than total misses.
Looks like Russias short range SAMs are begining to outrange western mid range missiles the us army will be.... oh wait they have no mid range SAMs nor do they have any close range ones
The US Army has Stingers and Chapparal (ground launched sidewinders) and relies totally on its air force or navy for air support.
Hypersonic missiles with 60km range would be pretty interesting... even just with command guidance that would be interesting but with the new HERMES range of missiles having terminal guidance I would think a few with ARH and another few with ARM guidance and of course the IIR guided ones the Russian ground forces and air defence units will be very potently armed.
I don't see why upgrades to the missiles and systems could not be applied to Army units vehicles and naval forces... especially the latter with the 4 warhead anti drone missiles... they would be useful against a mass attack of subsonic anti ship missiles...
