The pressure wave is the biggest threat to the spar. If it gets bent enough, the entire spar collapsed. The fragments are kinda whatever, because they won’t end up really deforming the spar’s overall shape. However, in warthunder, because fragments are all that do damage, this sort of behavior is not seen.
The fuze isn’t instant. It can still pen stuff after the fuze is activated.
Not the point. Even if it was 800m/s it’s still far of the 1100m/s it once had.
Still only 11g so it would do some damage but not enough after a single shot. This is no MK108 or ADEN.
Looking at the video, the shell hit you from below, and basically detonated within your wingspar. So the concept of the pressure wave deforming it isn’t as far fetched.
It should be noted the way warthunder does it is so incredibly stupid as to be comical, but it’s no completely implausable
Here is a better look at them
I wish my SUB-I-II did that too…
Quite an ingenious design to be honest. I really like the simplicity and fact that it locks together enough to basically transmit force as the wing bends.
You can see they needed 6 different extrusion profiles to make it, plus that some of them have worn quite a bit over production and corners (and some sides) are rounded off lol.
It fuzes after 10cm. From where you were shot, the round likely penetrated at an angle from below, hit your wing, then detonated on the spar itself.
I think we’re misunderstanding each other here. I understand that the round won’t maintain 1100m/s, I know drag exists. What I’m saying is that plane velocity matters as well as it can greatly impact the net relative velocity of the round.
I’m aware this isn’t a mineshell.
How the hell did they fasten those spars together lmao.
““The pilot in this photo is Lt. Paul Jessop. The photo was taken on February 14, 1944. Wee Willie’s last mission was on 8 April 1945. A direct flak hit and tore off a wing. The pilot of this mission was 1st/Lt. Robert Fuller and he survived along with some of the crew. Wee Willie was the second or third from last lost to the 91st durning [sic] WWII to be downed in action and was credited with 120 missions. Skunkface III was the last 91st B-17 lost, with the Harry V. Camp crew on board. Shot down by ME-262 Jets on 17 April 1945. Only the tail gunner survived.””

The tail is a single asset in the damage model.
The context of the image was not relevant to the point of this discussion.
The image shows spar failure. The flak hit did not" tore off the wing". That isn’t how that works. The explosive force and fragmentation causes damage to the wing structure which causes it to fail. This works the same with any explosive shell.
Ki-67 is not very survivable at all. I’ve spaded it mostly in Sim and any plane with 20mm cannons will almost always destroy you with just a few shots.
Key Aspects of the Damage:
- Initial Penetration: The 20mm HEFI-T round would likely penetrate the outer skin of the wing, which is made of lightweight aluminum. The round would create an entry hole, and depending on the angle and velocity, it could pass through one or more structural elements inside the wing, such as ribs and spars.
- Explosive Damage: Once the round detonates, the explosion would cause an internal shockwave, resulting in shrapnel and structural damage. This could tear through the wing’s fuel tanks, leading to a potential fire if the fuel ignites.
- Incendiary Effect: The incendiary component of the round would ignite upon impact or explosion, potentially setting fuel or other flammable materials inside the wing on fire. This could lead to a catastrophic fire, especially if the fuel tanks were hit.
- Tracer: The tracer component, although primarily used for visual tracking, could also add to the incendiary effect by igniting flammable materials upon impact.
Extent of Damage:
- Entry and Exit Holes: The round would leave an entry hole of about 20mm, but the exit hole could be larger due to the explosion and shrapnel spreading inside the wing.
- Internal Damage: The internal structure of the wing could suffer from broken spars, ribs, and damaged control surfaces, which could severely compromise the wing’s integrity.
- Fuel Tank Rupture: If the round penetrates a fuel tank, it could lead to a fuel leak or even an explosion, significantly increasing the damage.
- Fire Damage: A fire could spread across the wing, damaging electrical systems, hydraulics, and further weakening the structure.
Factors Affecting Wing Detachment:
- Point of Impact:
- If the round hits a critical structural component like the main spar (the primary load-bearing part of the wing), it could severely weaken the wing. However, even in this case, a single 20mm round would likely not generate enough force to completely sever the wing. It would require multiple hits or additional damage to cause the wing to detach.
- Cumulative Damage:
- If the wing has already sustained damage from other sources (e.g., previous hits from anti-aircraft fire, structural fatigue, or stress), the additional damage from a 20mm HEFI-T round could be the tipping point, leading to wing detachment.
- Secondary Effects:
- If the round ignites the fuel in the wing’s tanks, the resulting fire or explosion could weaken the structure further. In extreme cases, if a fuel tank explodes, it could cause significant enough damage to result in wing detachment.
- Flight Conditions:
- The stress on the wing during flight, such as high-speed maneuvers or turbulence, could exacerbate the damage caused by the round. If the wing is already compromised, the additional stress could lead to a catastrophic failure.
Conclusion:
- Unlikely from a Single Hit: It’s unlikely that a single 20mm HEFI-T round would cause the immediate detachment of a B-29’s wing.
- Potential for Severe Damage: However, the round could cause significant structural damage that, when combined with other factors (e.g., existing damage, stress during flight, fire), could lead to a wing breaking off.

Is it impossible? No.
Is it improbable? Yes.
Does WT have bad damage handling on models for bombers? Yes.

You are kind of bringing the pedantry late to the party.
You think a single HE detonating near/inside the spar has enough energy to deform it to the point of instantly losing the wing?
Even if it did that it would deform the whole spar but simply dent it at the point of impact. There’s a reason fighters went for the cockpit in frontal engagements and didn’t shoot the bombers wings to ensure a crash.
It can but rarely matters in ground/air to air combat as the round already have enough pen to pierce armor and KE transfer isn’t modeled.
These are about the only cannons I’d say can reliable take a bomber of that size down but even they have to hit more than one shell.
Ok, actually looking at the replay, you had the most bullshit death imagineable. he was firing APDS, and he didnt even hit your wingspar.you should not have died

The RNG damage in this game truly never fails to amaze me. No fun allowed.

Lol it was a desync kill. The round didn’t even hit you but it registered.
Well mystery solved, it was just game bullshit.
