yak 9T/ turret's syndrome

[Cavelife]

In AH, what round does the 9t's cannon fire? Research at the wikipedia level shows an HE and AP type. I dont expect to kill tanks, but tracking and turreting them is loads of fun despite mixed results. Is there an angle/ range formula that always does the job? Also, are those armor thickness charts online anywhere to print?

[Lusche]

In AH, Yak9-T shoots HE only. If ya like to kill tanks with big guns, I recommend the Hurricane D, or Il-2, B-25H. The Yak is not an effective tankbuster.
For armor values, I'd say the quickest thing would just be to go to hangar and write the armor values down. There ain't that many of them, it's probably much faster than looking for any online resources.

[WWhiskey]

The 9t can kill flak from directly above and a panzer from behind. That is all I can remember killing with it in a good while, and even that has been a long time ago

[Yossarian]

It can take LVTs quite well, IIRC.

If used properly, the Yak 9T will take out a Panzer in one pass.  Above and behind into the engine compartment, right behind the turret, the "sweet spot".  Just got to make sure your shots are pretty much in the same spot.  It's a safe bet that it's the same with the Panther.  Don't know if it can be done in 1 pass though as I haven't had the chance to up one against it yet.  M4's and T-34's will require more passes and don't bother against the Tiger.  I, personally, like using the Hurri 2D though if there are quite a few gv's, the IL-2 is your best bet as it holds a lot more ammo and has F3 mode.  I don't use the 25H as often, but it can do quite a bit of damage when used properly but is a pretty big target and not as nimble as the other listed planes.  The P-39 is one plane I have yet to use in a tank busting role, though it's 37mm is the same as the 9T's in that it uses HE rounds.  When it comes to armor, the 39 is better than the 9T and if it's 37mm is at least as good, then it should better in a tank busting role.  Gotta up a P-39 next time there are some gv's running around.

[Karnak]

The P-39's 37mm is complete crap compared to the Yak-9T's 37mm.  Much, much lower muzzle velocity and, IIRC, a lower rate of fire as well. Don't think it packs as much HE either.

[Volron]

Then it will be a pain in da arse to take out a tank with the P-39.  I might give it a go anyway, just for the spork of it.

I have never seen a reference about AP ammo regarding the Yak-9T nor the P-39.

I did find this, From Soviet Air Force Fighter Colours 1941-45:

With little surprise, firing trials revealed that the NS-37 would be devastating - it was capable of penetrating 30mm of face-hardened steel plate at up to a 45 degree angle from 500m, and 45mm of steel plate at 90 degrees. The NIPAV's supply of derelict airframes was also placed into severe jeopardy by the Yak-9-37, every one fired upon by the NS-37 being completely destroyed; even twin-engined bombers like the Il-4 would break up when struck by such a shell.

There being no mention of a differentiation of ammo used in the tests.

I recall Tony Williams posting that the Yak-9T carried HE rounds for air-to-air combat.  It wasn't intended for use against tanks.  The Il-2 carried AP ammo for its NS-37s.

[SmokinLoon]

The HE damage of the US M4 37mm and the Soviet NS37 are exactly the same in Aces High (17.1), the rate of fire does favor the NS37 by a wee bit, but when we're talking less than 32 rounds of so for either the US or Soviet cannon, the rate of fire should be less of an issue and damage and accuracy should be more noted, imo.

The NS37 does have a higher velocity and therefore a bit flatter trajectory, but hardly enough to mention.  Against ground targets, both the P39 and Yak9T do the same damage.

Isn't the M4's muzzle velocity something like 600m/s and the NS37s something like 900m/s?  That seems like it is worth mentioning.

[Lusche]

The M4 (P-39) projectile has ~127KJ kinetic energy at the muzzle, the NS-37 (Yak9-T) ~298KJ

Sure, in terms of trajectory and accuracy/time on target especially for fighter vs fighter duels.  In terms of damage... no.  You're main point in your previous statement was that the US 37mm is "crap" vs the Soviet 37mm.  In terms of damage vs OBJ and vs GV's, due to the HE nature of the warhead, they are in fact identical. 

Put your purse away, there is no need to go granny on me.

In terms of damage: Yes.

Kinetic energy is a factor in this game. The sole exception is when shooting at objects (town buildings, hangars, ack and so on.) Gv's are no objects in this context.

The HE damage of both 37mm's is the same, 1 round vs 1 round.  Please explain to me just how a tread on a tank, or the tire on an M8/M3/M16/251/jeep, or turret on a Ostwind is going to be effected differently by the 2 different 37mm HE rounds.  For that matter the top rear armor of a T34x, Panther, M4x, etc.
