Only because it didnt need it in the first place.   :aok

The Stuka G is NOT going to be any more of a force than the Hurricane IID.  Mark my word.   ;)  

If its a more stable platform it will ne more of a force. Thats the one thing I liked about the IL2, its more stable on the dive. At least to me.

My method of attack was to dive at a steep angle, not super steep but stepp enough, and come in a bit shallow keeping the tank right on the top of my sight ring/view. As i got closer the tank would line up with my crosshairs. At the point of crosshair alignment I'd be about 300 away giving me at most time for 4 shots at 300 to 200 away. Then I'd pull up sharply, not TO sharply cause I was controlling my speed on the dive. But not to slow either cause I'd immediatly convert "E" back to a steep climb to stay away from the guns of the enemy GV. I never hosed and always aimed for the thin top plate in the tank.

For some reason the Hurri D fights my stick to much, even with variou forms of trim. If the new Stuka has the stability of the IL2, and some of the agility of the Hurri, it will be a good platform. Maybe the best. But guys are going to have to learn to fly it like a flying tank and not a 200 round one either. Theres only a couple of very good Hurri-D sticks in the game. Im betting the Stuka will fair a bit better but your going to have to conserve ammo and be a sharpshooter.

Attacking the top armor may not be the most effective attack profile.  The round performs poorly at strike angles over 20 degrees and loses energy very fast with range.  It will cut through a lot of armor at short range and a flat strike angle but that's not what you typically get when attacking down through the top.  I haven't really ran the numbers but my feel is that you'll probably be better off to go at the rear or sides and try to make your attack angle perpendicular to the armor angle.  Then wait until you're at close range to shoot, hopefully where you have your convergence set.


IDK about everyone else, but when I get back on, I intend to perfect the diving attack.

Dive angles of more than 60° are very difficult to pull of, particularly vs moving targets, particularly as one tends to estimate the actual angle higher than it really is. I'm 'perfecting' this attack for 6 years now and still end up with 45° attacks mostly  :lol

Never said it would be easy, but I'm gonna try.

If I had to take a guess, the biggest problem is going to be judging how far ahead of the tank to initiate my dive. If you don't get that right, the angle on your firing run is going to be shallower than you would like.

From an older thread on the same subject:

The Hurricane's 40 mm Vickers S guns are very much inferior to the Stuka's 37 mm BK 37. The Vickers' has a muzzle velocity of 1,870 ft/s, or little more than the MK 108 spud gun. The BK clocks in at 3,836 ft/s with APCR Tungsten rounds (standard issue on "Gustav the tank killer"). Almost 1000 ft/s more than the .50 cal. For comparison the Il-2's N-37 clocks in at 2,260 ft/s.

Back to platforms. Im interested to see how stable the JU-87G really is going to be in comparison to the IL2 and Hurri-D. My early tests indicate a very stable gun platform, with the Stuka we have now". Remember the 87G was not a light airframe, it was almost as heavy empty as the IL2 and far heavier then the Hurri-D. It had substantial wing area too which is a plus with the IL2. Its power/weight ratio is its archilles heel however. Your going to have to come in fast to have the energy to get verticle again. The Hurri-D is not a horespower giant either but at least it was light compared to the stuka. The 87G is not going to fair well against enemy fighters.

I honestly dont know how Rudel did it. No matter what you think of him personally he was one hell of an airman.

Honestly the M4 37mm on the P-39 should have the highest penetration! It has a higher velocity!

I noticed on the screen shots that there were angle marks on the side screen, it may make judging the angle by eye easier after a few tries.

Since we are now up to 3 dedicated tank attackers with wing cannon designed to penetrate armor. I wonder if it's time for HTC to add in the dropdown menu for their ballistic penetration info for each individual cannon.

Round(AP)(API)(APC)(TungstinCor)(SteelCor)(CartoonCor)---ft\sec or m\sec
Range
Angle
Penetration

The dropdown armor info for the tanks indicates shooting at the rear deck of the tank at 45-60 degree angle will reduce the natural effect of increasing armor thickness by shooting from too shallow of an angle. Or not firing untill inside of 300 yards except at open top turret. WW2 NS-37 tests reccomend 300m and closer. Risky business if you don't keep track of wirbels and the tank's turret direction. I see alot of IL2 and B25H killed that way while on full zoom in 88's.

Since I'm obviously the tank in your analogy I must be wearing body armor. Since the .45ACP is the slowest and fattest bullet (Vickers-S analogue) I'd prefer that... Try to hit the chest plate, please?  :confused:  :uhoh :D
