The JU-87 W/37 or the HS-129 would be fine with me.

The thing is. . . it should be relativly easy to add - 2 gun pod options.  I know its a diffeent model - but that too can be changed with relative ease since its bascially the same plane with very minor differences.  I could understand that adding a brand new plane would take a great deal of time, or even adding some new models (like the yak-3, which would be almost like adding a new plane). . .

HiTech? tap tap tap.........is this thing on? We have been requesting or hearing about this popular request for years. Is there a reason it cannot be implemented or is it under consideration or developement? Just to put this issue to rest one way or the other. My 2 cents is do it. Would be another great addition to game.  :cheers:

to wit, the p39.. I cant remember the last time I saw one in the MA..

i guess u have come across me to often.
P-39D 74kills  64deaths all latewar MA
 thats for this month

and the US p-39 37mm did have AP ammo which might make it a tank killer.... but we only have HE here

Is there somebody with the ability to maybe model the guns as an unofficial "hack" for offline mode?  I'd love to see how it flies and shoots.  Not necessarily an accurate model but changes the weight to an appropriate number and changes the guns to shoot a large projectile instead of the bb’s?  It is just a thought.  Again, this would not be for use in any arena. 

We may find out that is totally sucks..... :D

BK 3.7 (Pz.Gr.)AP 860m/s
NS-37 AP-T 880m/s

Both have tungstin cores of different sizes and conical covers.

The NS-37 AP-T is 752g with a long pointed ogive. Over all length of the round is 194mm.
BK 3.7 (Pz.Gr.) is 410g with a short pointed ogive. Over all length of the round is 114.5mm

External ballistics favors the NS-37 at longer distances because its round is heavier, longer, and has a longer ogive(nose) starting from a higher initial velocity. It is more stable which is what you want in an AP round. Penetrates 50mm of armor at 200m. The shorter BK37 AP will have parabolic dispersion problems due to its short nose and short OL.

If you ever look at the Ju87-G1 armerors guide it shows a horrendous dispersion cone of 3m at 400m for each individual BK3.7. The crossing point for the two guns is at 400m which reduces the dispertion for both combined at 400m to 3m. Wider dispersion means the point of the round may not be hitting dead center on it's own axis which will contribute to the targets ability to cause it to not penetrate if its angled to the round.

The armerors diagram shows the Revi line of sight set level to infinity. The BK3.7 is elevated to fire up and cross the Revi line of sight at 375m. With both the NS and BK you get the sense distances were very close to kill anything with armor plate on it?

BK 3.7 Specifications
•   Type: single-barrel automatic cannon
•   Caliber: 37 mm (1.46 in)
•   Cartridge: 37 mm x 263
•   Operation: Short Recoil
•   Length: 3.63 m (11 ft 11 in)
•   Weight: 295 kg (650 lb)
•   Rate of fire: 160 rpm
•   Muzzle velocity: 1,170 to 780 m/s (3,836 to 2,557 ft/s)
•   Projectile weight: APCR 380 g, HE 640 g, AT 685 g

The remaining German guns were all adaptations of ground guns. The first was the 37 mm BK 3,7, a modified version of the FlaK 18 AA gun firing the same 37x263B ammunition. This meant that it was bulky, heavy and slow-firing by comparison with the NS-37, for example. It also remained clip-fed, with a maximum capacity of just 12 rounds. It mainly fired Hartkernmunition ammo, capable of penetrating up to 140 mm / 100 m / 90 degrees although this was halved at a striking angle of 60 degrees.

NS 37 Specifications
•   Type: single-barrel automatic cannon
•   Caliber: 37 mm (1.46 in)
•   Operation: short recoil
•   Length: 2455mm (N-37D)
•   Weight (complete): 103 kg (227 lb)
•   Rate of fire: 400 rpm
•   Muzzle velocity 900 m/s (HE, HEI-T), 880 m/s (AP-T)
•   Projectile weight: 735 g (26 oz)

The NS-37, unusually for the USSR, used a short-recoil mechanism and was belt-fed. It was a particularly slim weapon, with a compact mechanism, suitable for fitting between the banks of a liquid-cooled vee-engine to fire through the hollow propeller hub. The powerful 37x195 ammunition is quoted as penetrating 48mm / 500m / 90 degrees, enough to pose a threat to the side or rear armor of virtually any tank.

Um who's right?
