Ju-88 Guns

[Semir]

Do not have videos at the moment, but I noticed that the Ju88 gunner mounts become incredibly inaccurate even after a short amount of fire. To the point where the gun would shotgun spray in ~20-30 degree cone.

 

I believe Ju88-A4 uses belt-fed MG17, same ones as the 109 and he111 use, and I have never noticed either 109 or he111 having any overheat accuracy issues even with prolonged firing. In the case with Ju88 firing the "full clip" equivalent of he111 will already cause the spread to worsen significantly.

 

 

Curious if anyone else noticed similar issue and if there is a particular reason for this to be a realistic behaviour? (overheating is understandable, but in such a short time? and feels like firing bursts also doesn't help all that much)

 

As a comparison the PE2 gun, which is also belt-fed, does not suffer such accuracy loss from the sustained fire.

Ju88 doesnt have MG17, they use the MG81, which has a much higher fire rate compared to the MG17s.

Thanks for the correction! My question still stands though, as the overheat happens too quickly (for my feels) and has an incredible impact on the accuracy.

The MG81 overheats after around 5-6 seconds, which equals 120-150 rounds. The MG17 overheast after around 8-10 seconds (possible even a bit longer at higher speed, due to the stronger airflow cooling the weapon down) and it has only ~70% the rate of fire of the MG81. The MG15 of the He111 has a 75 round magazine, so it's pretty tough to overheat before you have to reload.

Sorry Matt, but as far as I remember, the Devs gave the MG81 1500 rounds per minute, so shooting 150 rounds lasts 10 secs. And even this seems to me in flight in 4000m altitude with 10-20° belowe zero, way too short. With german MG3 with 1200 rpm you can easily shoot 200 rounds without overheating, on the ground without airstream and much higher temperatures.

Maths Fail.

In 10 Seconds a single gun fires 250 rounds. A Minute has 60 not 100 Seconds.

Not that i even pretended to claim that the current overheating is accurate, but it seems to be accurate anyway.

Oops, yes Klaus, you are right, Math was never my strength.

But there is a difference between a hot barrel and an overeated barrel. You can still shoot with a hot barrel and hit your target. It is only a problem, when you have weapon disorder, as a round could get fired by the heat of the barrel.

In what circumstance would you be engaging in "prolonged firing"?  In RL, if you were doing something other than short 1-2 second bursts you'd be doing it wrong.  Not only is ammo a scarce commodity in the air, something that must be conserved, particularly in a bomber, but prolonged bursts greatly increase the potential for a stoppage which, if it's a bad one, could put the gun completely out of action.

Hi Wulf, completely agreed. For me it was more a theoretical quesiton. I don't do long bursts in the game, either, exept, when the fighter is that near, that it is about now or never, as it does not make sense to keep your ammo, when the only thing you need is your chute. Long bursts is a problem of my AI gunners, as they shoot to soon and to long. Even, when I order my gunners to shoot on short distance, they start shooting on too large distance. And I can not give this order to the gunners of the other aircrafts. So they shoot around them like idiots, never hitting anything, and when we get attacked they are out of ammo.
