Post About Bomb and Rockets...

They seem a bit unrealistic.

Seems TD decreased the Blast Radius of the Bombs and Rockets drasticly, just to something wich they believe to be real or something, while infact even a 2.5KG bomb already has a Blast Radius of 10 Meters... so it might not take out a tank if it drops next to it, but its surely capable of taking out a car or a truck etc. if its with in the blast radius.

Same goes for the Rockets, they pack an explosive warhead with enough power to destroy a car or a truck easly even if you dont hit them directly.
But now it seems you have to hit everything directly to score any damadge at all to an object.

Small Bombs dont have a Self Arming time at all, if you would drop them they should blow up on impact right away, this is especaily anoying with the Bomblets wich you need to trow out over a colum of vehicles from very low altitude but dont do nothing anymore though.

Shouldnt be to hard for TD to program the small bombs and bomblets so they dont have an Arming Delay of 2 seconds.

The Torpedoes... well i dont know, seems the alt/speed restrictions are a bit strickt on some.
Seems to me that any of the Torpedoes should be able to be dropped from the minimum altitude of 30 meters and 205Km/h (or what ever the lowest drop altitude/speed is for the Mk13 and 45-17's)

Arming distance in water for the Torpedos seems a bit much also, as this could be adjusted. Dont think the IJN had a 600 meter arming distance on there torpedoes wen they attacked pearl harbor, also there was a stricke on a harber somewhere in italy or something in WW2 where they Allies managed to Drop Torpedoes inside the Torpedo netting at prety close range to the ships.

I think you're referring to the raid on Taranto, where they used Swordfish biplanes to attack the Italian fleet.

You also mentioned Pearl Harbor, which is a well documented case of using modified torpedoes, so that got me thinking: maybe they used modified torps on the Taranto raid as well?

The way i understood it is that the torpedo restrictions are not only about the warhead surviving the impact with the water. It's probably acceptable knowledge to all of us that if we drop too high or too fast the impact with the water will probably damage the torpedo, that's the obvious part.

However, from reading the 4.10 documentation i get the idea that the combination of speed and altitude at the time of drop factors into another restriction, namely the torpedo's angle of impact to the water.
If it's too shallow, the torpedo is not sufficiently submerged to make optimal speed (maybe the propeller is only half-submerged?), but if it's too steep the torpedo goes too deep and can't self-correct its course, so it ends up missing?

I'm not exactly sure about how it works so maybe someone from TD can explain better, but it makes sense to me if it more or less works that way. After all, these were not modern torpedoes and they were somewhat sensitive in terms of guidance and malfunctions, not to mention duds and premature detonations. Incidentally, this last one would also explain the need for excessive arming distances. I'm not an expert on torpedoes so corrections are more than welcome if anyone can share some references, it just happens to make sense to me from what i've read in combat reports and seen in-game when i used to play silent hunter 3 with some realism mods a few years ago.

As for the Pearl Harbor attack i vaguely remember that in order to drop at the correct angle and still do it after passing the torpedo nets, they added extra stabilizing surfaces to the torpedoes carried so that they would run closer to the surface.

Nothing has been changed about rocket or bomb blast radius, small bombs usually had a safety mechanism or some other altitude restriction. Torpedoes had particular release limits that went both ways, minimum and maximum. The Japanese torpedo works from 200m away.

No AO-10 are more powerful?

I personally like using bomblets from higher altitude (eg. in the Il-2). However, it is difficult while flying aircraft which only carry four AO-10.

@Blackdog: i know about the angle etc. there saying to low ad its gonna skip on the water...
Sure thats true if you for example try to drop a Mk13-Late from 30 meters at 400Km/h, but not if your droping it at 30 meters and 205Km/h.

On the Blast Radius of the Bombs, something was changed because everyone i fly with is complaining about the bobs being less effective.

IL-2 flew at verry low altitude over the battleflield dropping bomblets on the ground targets, at less than 50 meters in altitude, you cant do that anymore now.

Also i think the torps should be set at 200 meters runtime in the water, or maybe even less for japanese torpedoes so you can do the 2 raids mentioned above.

You can as of 4.101.

If you are too slow the angle of the torpedo is too steep -> as bad as too fast!

You can do it now. Minimum drop height with the new bomb fusing is 25 meters. That happens to be less than 50 meters.

Not if your lower and slower than the drop speed, you can also see this with Torpedo bomber footage and pictures on the internet where they are just a few meters of the waves (less than 10) wen droping there torpedoes.

If your flying at the recomended drop hight and are going to slow than the torpedo will nose dive yes, and if your flying to low at the recomended speed than it will skip.
but if your flying low and slow the torp will hit the water correctly.

The problem with pictures is that it's hard to tell what happened just prior to and after the shot was taken.

Regarding the TBD, it's not really possible to tell how high he is. It depends a lot on the height of the camera. If the plane is low, then consider that the torpedo is slung with the nose down rather than perfectly horizontal.

Regarding the G4Ms, it's quite possible their torpedoes did not arm. It's also possible that they are hanging low to avoid flak and will bounce up at the last possible moment to release their torps. One has to ask because there is also a Betty that is close to the appropriate drop height.

The lowest drop-height mentioned that I can find is 23 meters, the vast majority of sources saying 30 meters or so. I can't find anything describing successful wave-height releases. Even if it was even possible by going slower, you would be putting yourself at great risk to enemy fire by doing so.



At 1:00 you can see the torpedo jump out of the water because it was released too low.

Regarding success at Pearl Harbor, of 40 torpedo planes present, only about 15 fish hit ships (which were totally stationary btw).
