Best 37mm?

[Slade]

Guys,

With respect to ACM usage, which prop fighter plane has the best 37mm?

Examples: P-39, Yak9t ...

Thanks,

Slade

 The yak has the NS37 which has a much higher MV than the 37 oldsmobile or as I call it the buick37!

  The 37 MM on the stuka is closer to the NS37 but like the IL2 it fires AP rounds.

Not the P-39, that's for sure.  Well, at least in real life the Oldsmobile 37mm cannon sucked.

Yak-9T's NS-37 beats the P-39 in about every category: Trajectory, rate of fire, damage.

What about the BK-37 vs. the NS-37?

What about the BK-37 vs. the NS-37?

In the context of the original question, usage as an air to air weapon the NS-37 hands down - higher ROF, more ammo per gun and (in the Yak-t) using HE rounds instead of AP.

But that's not a fair comparison, as the BK-3,7 is a AT gun fitted to a dedicated tank buster. Comparing the NS 37/Il-2 combination to the BK-3,7/Ju-87G is that one sided anymore. But in AH, the NS-37 still wins:

While having a somewhat slower muzzle velocity, the trajectory of the NS-37 is still flat enough. The BK has a substantially higher armor penetration under ideal conditions, but the nature of the Hartkern ammunition makes it very sensitive to even small deviations from the ideal angle of impact (90°). And the NS-37 can still dispatch about any tank in the game. Finally, the higher ROF and much higher ammo count of the NS-37 in the IL-2 makes attacking not only tanks, but also small fast moving ground vehicles like the M3 much, much more easy.
Similar to the 40mm of the Hurri D (and most probably even more so), the BK-3,7 of the Ju-87G is much more a specialist's weapon.

Yes, I was primarily thinking of tank-busting.

. The BK has a substantially higher armor penetration under ideal conditions, but the nature of the Hartkern ammunition makes it very sensitive to even small deviations from the ideal angle of impact (90°).

Is this effect seen in-game, or only in real life?

By my perception it's also seen in game, but I have not (yet) tried to test it more objectively

[BnZs]

Does it show you the round deflecting off as in tank v tank warfare, or do you always get the big orange cannon flash regardless of penetration?

In offline testing with the BK 3,7, I've gotten the dreaded light saber effect ricochet from 1000yd shots.

[FLOOB]

The stuka's 37mm ap has much better penetration than the ns37 ap round. I may be wrong but something like twice as much penetration.

Yes, but as pointed out by Lusche a little bit above your post it is very sensitive to deviations from a 90 degree impact angle, more so than the NS37's plain Jane AP rounds.

I've done a bit of tank shooting with it, haven't ever gotten anything but the big orange flash, but several times I've not gotten a kill with just one shot...I dunno.

[Ack-Ack]

The stuka's 37mm ap has much better penetration than the ns37 ap round. I may be wrong but something like twice as much penetration.

Maybe that's due to the Flak 18 37mm cannons on the Ju-87G series using tungsten carbide rounds.

Ive at least smoked most tanks in the game with the NS-37 in the Yak but i dont consider it a very good tank buster. Panzers yes. Lighter GVs yes. Ive killed some T34s with it but consider it a low percentage most of all the T34/85.

The Yak-9T is a murderous base defender tho. If i had to pick one airplane to Shepard a town it would be it. LVTs, M3s, goons, M8s, dont stand a chance and the MGs are great for hosing troops. A low Alt pack of bombers has a big problem with the NS-37s and their HE tips. Porking fighters had also best stay out of their way. I like to fly it about 2 to 3 k and keep it fairly fast, leaving enough air under neath to give it a few evasion moves. It rolls pretty well and retains enough energy to make it fairly agile in its best speed range. I think its under rated.

Comparing the Hurri-D to the Stuka I cant speak much about the guns but the Hurri is the more stable platform.

I'd really have to see hard data to believe the 3,7 had twice the penetration of the NS-37 AP.
