I talked about that exact issue when I was trying to test .50s on the He-111 in my bug report. I had to use the Bf-110 as a surrogate as it offered direct unrestricted access to the fuel tanks.
Yeah. I wanted to use the Bf 110 in the first place but then ended up with the He 111.
I now tested the Bf 110 and it took around 10 hits to set the fuel on fire. Firing with just one MG at times.
So as expected, the fire chance of guns seems to have been nerfed quite heavily, since there were times where 1-3 .50cal would cause a fire.
You can have it SOMETIMES light up fuel tanks easily. Like on the Bf-109 F-4. But the amount of one shot fires I got pales in comparison to the amount of times like in the video provided where you’re hitting multiple times and you’re not doing much.
Yeah F-4s light up pretty fast using 12.7mm Berezin API-T. Often just one hit is enough from behind.
But maybe it’s due to the round kiling the pilot which lights the AI plane on fire automatically or something.
With Berezin API-T, Bf 110s also seem to take anything from 1-10 to light them on fire. Even though it felt more consistent than with Breda-Safat API-T. So I was thinking the fire chance might be related to the damage inflicted.
Universal belt, F4U-1A (AP-I/AP-I/AP-I/T/I). Made 3 passes: Pass 1 I barely nicked his tail. Pass 2 I didn’t hit any fuel tanks. Pass 3 I hit his engine. Uploaded above is the engine shot causing immediate fire.
- AP-I: M8 Armor-piercing incendiary bullet
- T: M1 Tracer bullet
- I: M1 Incendiary bullet
(notice that although his wing is yellow, i did NOT hit the fuel tank:

)
Regarding 0.50 cals:
In this replay 5 kills with 0.50 cals (universal belt - 3.3 UK Hellcat 2.7 - 3.7 game):
Gaijin Entertainment - Single Sign On
Kill #1 - I-185 - 3 hits and exploded
Kill #2 - P-47 - 2 hits and engine fire - burned down
Kill #3 - MiG 3 - 3 hits and engine fire - burned down
Kill #4 - P-39K - 3 hits and immediate crash
Kill #5 - Il-4 - 2 hits and engine fire - burned down
Between #4 & 5 i caught an ai Il-2 - 3 hits and dead…
Number of individual hits taken from battle summary. 65 ping, 0 PL, CIS server
From my pov no buff needed…
btw
saber hit all of your fuel tanks, yet no fire ever broke out?

IRL It’s mostly due to kerosene and fuel tank placement that stops fires on jets from happening as often.
It’s easier to look at props. Especially when gunning down Mosquitos or Pe-8s. I’ve shot up their entire wings and did damage to the fuel tank and no fire. But if you hit one little engine it’ll go up easier. In reality, due to movement within the aircraft, the sloshing of the fuel should exacerbate many of the issues that can be observed when a fuel tank is struck especially as it enriches the ullage as the aircraft flies around.
Honestly at that point. For props, just use Universal. Most of the damage comes from the m23 incendiary round, so it’d be better if Gaijin just changed the ammunition belt to be accurate.
For Late-war belts, should be: API-T, I, API-T, I, API-T
Mid-war: API, I, API, I, T
Early-War AP, AP, I, I, T.
We’ve had this conversation super far back:
Replays don’t work as evidence besides showing the raw damage to an aircraft because tracers don’t line up with a live match. You need raw footage.
This image would just be as applicable.
I’ve used stealth belts and looked at sensor view for the “Tracer fire” and the rounds go way shorter than what shows up in the live match.
Hits appear to mean more like burst.
Otherwise I would get like 50-100 or more hits per aircraft, using a Spitfire with 8 LMGs.
Probably it counts damage within 0.1s that didn’t destroy any component as hits.
Made a report about incendiary bullets
https://community.gaijin.net/issues/p/warthunder/i/UPY5AVA9rNtR
And then gaijin makes it where it basically does nothing to fuel tanks. You’re going to run into the same issues when people were begging gaijin to add damageable modules to tanks. They add it in in the worst way possible.
Most likely scenario is that nothing gets changed at all.
I mean nothing happened with my report that Incendiary ammo is generally underperforming.
uh but it IS the best belt?
I is AS insendiary as API, but with less pen so no fuel tank pens and pilot headshots through armored chair.
It perplexes me that such a wrong statements gets that many upvotes.
Not sure where he’s got that idea, other than maybe the stat card animation, which for some reason shows API bullets exploding on impact.
well firstly thats strange that API and API-T have different animations xD
But as muc as i know them incendiary rounds dont explode at all, thy have chance to set plane on fire

there are explosive bullets ingame for 50cal, but only for italian, japanese and sweden ones
And German and Soviet
Ah yes. They arent the HE tho, but they`re rather similar. The МДЗ for Berezin and MG13
It’s just a different designation but they work just like other explosive bullets
