Changes to Bomber Survivability Feedback and Discussion

this is a 75mm cannon

You cannot replicate this in-game. Not even close. A hit to the same area results in a yellow wing spar, not even close to the immediate catastrophic failure that was caught on video.

There may be another aspect we’re not considering, theres only like 3 predetermined positions the wing breaks off ingame, close to the root is not one of them, recreate these shots near engine 1, see how that works out. This isnt a bomber fault thats a low detail damage model across all aircraft at that point

  1. already did

  2. Even if that section was unbreakable, IF the wing spar was blacked out we could consider it to be close enough to reality. But in all cases it was turned yellow at worst. The wing section was also not blacked out, it was red at worst. This is clear evidence they are overperforming hugely.

  3. Zero fuel fires the whole time despite the fuel tank having a huge hole blown into it by a 75mm HE shell coming from below, which is pretty much impossible

Well, in a test, the Germans detonated a 50 kg charge at a distance of 12.5 m from the wing of a B-17, and determined that the damage was only enough to make it “unfit for combat” (kampfunfähig), meaning the aircraft still retained its flight capability.

It should be noted that the damage effect is amplified by ground proximity, which reflects the blast wave; in a free-air detonation (where pressure drops off much steeper), the damage at that same distance would be practically negligible. In fact, according to the tests, with a 50 kg charge the threshold distance to make a B-17 ‘incapable of flight’ (flugunfähig) is 10 meters on the ground, but approximately 8 meters in free air. With 2 kg (a charge larger than that of a 10.5 cm Flak shell), the threshold distance is approximately 1.0 meter in free air - meaning that beyond this distance, the blast is no longer lethal.

The destructive power of an unconfined blast wave - that is, one that does not detonate inside an enclosed compartment of the aircraft - is therefore extremely limited. This is probably why Flak didn’t bother with large explosive charges, preferring instead to burst heavy, high-velocity fragments into the center of bomber formations, which gave a far more effective kill radius. A 10.5 cm Flak shell, for instance, was 90% metal body and only 10% explosive filler, in contrast to the 40% explosive filler in aircraft mine shells

Even with the high explosive filler ratio of mine shells, blast wave effects remain surprisingly limited without the proper conditions.

According to the source in the Devblog, for an 18.6 g explosion (20 mm M-geschoss) to tear a 1.0 mm thick aluminum alloy sheet, the explosive must detonate no more than 12 cm away.

How then can it be explained that a hit on the tip of the vertical stabilizer can completely destroy the horizontal stabilizer far below, or that the 3.5 mm thick web of a Lancaster spar can be torn open by a hit located more than 2 m away on the trailing edge?

With this data, it makes complete sense that this Do 17 wing didn’t snap at all, even after 20 hits. Without proper delay fuzes, the blast wave alone will never reach the internal structural members. They are just detonating on the surface, essentially in free air…

In game, yes. IRL, no. M-shells had a fuse delay so that they exploded roughly after 10cm of travel after hitting the aircraft’s skin.

What kind of charge? This does not account for the missile itself flying at a speed much greater than the bomber’s.

20? it was hit HUNDREDS of times

How big are these holes? How do they align with your predictions?

People genuinely forget that I’m talking about War Thunder.

This plane was hit by a Japanese 12cm Type 10 gun, and the shell that struck it carried 2.5 kg of explosive filler. You’re comparing that to a 75mm shell with only 350–400 grams. Look, I’m not saying a 75mm wouldn’t deal damage, but it couldn’t possibly do as much damage as a Type 10.

The minimum you’d expect from this is a huge fuel fire. I have NEVER seen a fuel fire happen in dozens of tests.

Soruce:Google free right?

Furthermore, the area targeted by the aircraft was heavily fortified with anti-aircraft weapons because American takeover of these areas would have meant an early defeat for Japan.

I’m pretty sure you were raging after just 10 hits. “How on earth is it still flying?!”

Yes you’re right it definitely must have been a fuel fire.

No mention of 120mm cannon being used and another user said it was a 75mm

I was the one flying the bomber and recording it. It was hilarious. Definitely not “20 hits”.

By the way, imagine you get hit by a 120mm cannon and you’re going to die in 2 minutes, and later the guy describing your death tells it with this tone of voice and this music. Personally, I’d be sad. Damn.

It had to be 120mm because in Palao Islands they only had either 80mm or 120mm anti-aircraft guns.

Correction: You’re right, there were 75mm guns, not 80mm, but military reports already list them as 75mm or higher caliber. If you’re presenting this image, you should have known that.

Note: In my opinion, this must be a 120mm cannon because expecting such explosive damage from a 75mm cannon would be a bit much; this was definitely a 120mm cannon. Of course, these are just my opinions.

Altitude and distance reduce explosive warhead power.

Video proof says otherwise, along with German documentation.

Ad Hominem and no real counter evidence does a great job at proving your point.

War Thunder does not simulate degradation of materials. Repeated impacts do little but reduce HP of modules.

More Ad Hominem. It’s so believable that ChatGPT made me say direct and not just impact, when it was Grammarly just trying to revise for “clarity”.

In reality, I’ve been fighting it from correcting empty space to just space as well.

You’re showing impact holes from a direct 30mm impact. It has little relevance to the missile claims.

And reduced HP will eventually lead to their failure. But apparently even 3400rds from a modern rotary cannon isn’t enough for a WW2 bomber. Neither is a 75mm cannon.
