In most/all of those simulators/games its fairly easy to score 10%+ hit ratios attacking

CFS are useful games for giving a person an experience of the general feel of things and the kinds of problems aerial gunners had to solve. Well, most of them. It's been a while since I used on playing in the bomber role. I don't know how the CFS treat the B-29 computer.

That said, CFS are just games, so they don't provide a reliable measure of the "reality" against which you'd measure some other sim. My sense of the history from too many sources is that a 10% hit rate for a fighter shooting at any target in a CFS (save for those close in their target's 6 o'clock) is probably light years better than the real world hit rate, so the CFS probably got something wrong. But that's a separate discussion IMO.

Erkki,

*chuckle* Do you think such a video will actually effect change in opinions? You're an optimist [:D] It'll get bogged down in what hit rate you got and avoid the issue of the fact that the hit rate of one will be, reliably, larger than the other. Even if you get agreement on that it'll be "Oh, a game's a game, it can't model this properly". Good luck to you though, I think it'd be interesting [:D]


Jaroen,
Hmm, you are welcome to your viewpoint. I think you are seeing insults where they didn't exist and some of the other things you say I contend - that all bombers' guns were hand-aimed ( which I, for example, never said ) - don't correspond with what I said either. With that said you are welcome to your viewpoint. Given the innacuracies in your initial post though I'll leave it to others to engage with you. I don't care to get into giving quotes to support things I never said - the "show me a quote that says Elvis is an alien" situation.

One thing I will say about all of this "oh that's a veiled insult" misinterpretation. Honestly if I think someone's a lying a**hole then I have NEVER had a problem telling them that to their face on the forum. I think that old-timers will be more than happy to testify that I'm happy to give my opinion of someone - for good or ill - directly to their face. I find sneaking around insinuating things to be dishonourable. If I wanted to insult mdiehl I'd have come right out and said it, I wouldn't have bothered with asides and veiled insults. It might be a strange defence but it is the truth ;-). Of course, you are welcome to believe whatever you wish.

KOzakh,

Thanks for the contributions. Very interesting stuff.

As re: the B29 claims vs MiGs. Aye I recognise that 26 MiGs claimed downed was probably 3 or 4 times higher than reality ( at least ) but since I was having difficulty getting statements like "I didn't say FCS was worse than B17 turrets, just less accurate than fire from fighters" getting interpreted as anything other than "I'm saying FCS was useless and the worst thing on the planet" [:D] I didn't really want to open the can of worms of just how inflated those claims were. I'm a bit surprised it was zero but not too surprised it was a single digit number of some sort.


As re: bombers and bombloads.
Well it depends on what you attack and how the game models it.

Vs runways and service areas what matter is whether or not the bomb hits PLUS its damage potential ( effect ). Basically with runway and service damage 1 bomb hit with 1,000 effect creates the same level of damage to the AF as 100 bomb hits with 10 effect each.

HOWEVER vs supply dumps ( and HI, LI, Resources etc ) what matters is ONLY the number of bomb hits. In that situation you are likely to get far more ( up to one hundred times ) supply hits ( or HI or LI etc ) with 100 x 10 effect bombs as 1 x 1,000 effect bomb. Basically a supply dump ( or HI etc ) isn't modelled as something which can be partially damaged. It is either hit and damaged or missed. So against those targets lots of little bombs work better.


As re: flying at night at 100 feet not being realistic. Aye, I agree it is probably over-effective in the game. With that said if you play a no rules kind of game then you have to be willing to accept these sorts of tactics being used against you. In the same way as my opponent doesn't complain when I send sweeps in at 42,000 feet and I don't complain when he sends kamikazes in over the ceiling of my F6F5s rendering them, effectively, uninterceptable I don't complain when he launches these low level night raids. I do plan to return the favour sometime though [:D]


As to mods:
Aye, I've made a mod which has put a lot of focus on toning down ASW over-effectiveness and the excesses of bomber defensive fire ( particularly in box formation ) as well as reducing the excessive effectiveness of bombers which carry a large NUMBER of bombs - simply by modelling those bombloads as sticks of bombs with increased effectiveness but decreased number.... These sticks of bombs thus maintain their effectiveness vs runways and service areas and infantry BUT have much decreased effectiveness vs HI/LI etc ( which I think helps make that aspect of the game more realistic as previously hit rates were far too high from strategic bombing.

If you wish you can drop me a PM with your email address and I'd be happy to email the mod on to you. It isn't a particularly large file.

For those who are interested, here's another interesting link that provides a really general summary of USAAF aerial gunner training. It doesn't go into the details of the trig, but it's got some interesting general statements and a pretty good bibliography.

Erkki,

*chuckle* Do you think such a video will actually effect change in opinions? You're an optimist [:D]

Some people's here? Hell no. This conversation is no more sharing views, its become a pissing fest. Not even when they see that the fighter is far from being limited to maneuvering at the same altitude as the bomber or to flying towards the bomber or at an intercepting path before shooting.

I'll need to do the fighter vs. bomber view comparisons in multiplayer but I have some nice super high speed head-on passes coming in the feared B-17E's blind angles. Theres actually quite a lot of real Luftwaffe anti-bomber footage in the youtube - majority of it is crappy shooting from far 6 (gun cams were mostly in Bf 110s and 410s only), but there are also some very high speed, 11-o-clock high passes where the pilot uses rudder to buy himself a quarter of a second more of shooting time before passing the bomber only meters above, through the cloud of debris. It was pretty "easy" for a fighter to give the bomber gunners a whole new dimension to consider while the bomber itself had to keep flying a very predictable course - straight and level.

BTW, about tracer rounds again. I have mr. mdiehl green-balled for 2 posts that ruined my evening that was very good until, but I saw him refer to tracers again. I wonder if he knows the tracers do not actually have ballistics equal to those of normal AP or ball rounds? They are lighter and burn their mass while they fly so they have less momentum, magnus effect effects them a lot more and they arent as accurate even in ideal testlab conditions nor do they fly the same ballistic path. Again, mdiehl probably hasnt shot tracers, or he'd know it is impossible to estimate distance as the tracers are just a red dots of light, without parallax. Even with parallax the best they help is seeing the vertical error and here come magnus and tracer's different ballistics again - correcting by tracers, even if you make tracers connect, does not guarantee AP/API connection or hits. Its more like shooting with a shotgun than magic lasers, especially as even B-29s's über God's own M2 Browning .50 cals arent recoil, shake/vibration or malfunction free. [;)]

EDIT:

Not going there. If mdiehl has a better tool for visual demonstration than a game or gun cameras (lets see him find a gun cam where the attacking plane is clearly hit and needs to abort its attack run(as presumably bombers per shot round get as many hits as the attacking fighter, per visible target's size at least [:)] ), heehee!

Yes, I knew that.

So did the guys who loaded them in guns during WW2. The deviation in their ballistics from other rounds was not great enough to suggest that tracers could not be used for correcting fire when shooting MGs, however. So I am not sure what you think you are driving at. Yeah, they weren't the same. Did the difference matter? Apparently not, or else one would think they wouldn't still be in use.

Again, mdiehl probably hasnt shot tracers, or he'd know it is impossible to estimate distance as the tracers are just a red dots of light,


You don't use them to estimate distance. In military use, you use them to adjust your fire.

True. But the difference between AP/API was, apparently, not great enough to prevent tracer from being regularly, ideed, routinely used to correct fire both in ground combat and in aerial combat. They're still used that way. So although you are correct to note that the ballistics differed, it's difficult to see why your point mattters. A difference that makes no difference isn't, for applied purposes, a difference that matters.

I can't think of one that is widely available. CFS are fun for letting you have an idea of the things you had to do, but it's still just a game. There's no apriori reason to imagine that the gunnery modeling in a CFS are a good basis against which to index a model in some other simulation.

I can't imagine where you'd get a gun cam that would provide the video you wanted. That'd basically be a bomber's eye camera shot of the attacking fighter. There are darned few examples of such film. Motion picture cameras were not standard equipment on any WW2 bomber that I know of.

Erkki,

Amen to that re: the fighter passes. I spent a couple of nice days on weekends a few months ago while reading about bomber turrets and anti-bomber tactics looking at gun camera footage.

Anyways, I'd be very interested in seeing what you come up with. It might even make me fire IL-2 up again.

mc3744,

No need to explain the need for the post. I think everyone wants to see enlightening discussion which isn't marred by a disagreement which gets out of hand. I can understand and support that. Obviously different people feel differently but I, personally, feel like I wasn't trying to have a fight with mdiehl but actually arguing the issues. I also feel that what my intention was certainly didn't seem to make a difference. Such is life as Ned Kelly would have said [8D]

Why engage with mdiehl? Simple, I believe that most people are trying to have interesting discussions and so I try to go out of my way - on the first occasion I talk with someone - to give them leeway for being enthusiastic, annoyed or just having a bit of a bad day. I'm not some poster boy for being perfect by any stretch of the imagination and I certainly remember a time 3 or 4 years ago where after a couple of posts with mdiehl I'd have called him some sort of unsuitable epithet. I've matured and so I try to remember that other people might be interesting and intelligent but just might be back where I was 3 or 4 years ago ( and I'm certainly not saying I've reached the end of my evolution in terms of maturity and so on and so forth ). Bottom line though I believe in giving people every chance possible before dismissing them as not having anything to contribute. Why is that? Well, I am keenly aware of how various organisations in Europe's past labelled individuals and groups as not having anything worthwhile to contribute as the first step on the road to silencing their voices in public discourse and then, eventually, trying to eradicate them. I lost family in that process and while, obviously, there's a world of difference between the nazis refusing to allow someone to argue against semitism on the grounds that "they have nothing to contribute" and me going "Gees, this mdiehl fellow just isn't worth getting into a discussion with in the future" I do still feel bad for closing myself off to ANY input from anyone.

With that said sometimes you do have to draw a line and say - Really he isn't bringing enough to the table to be worth listening to in the future. This is a pity because he clearly has a lot of knowledge but the other behaviour does, IMO, now outweight the knowledge's worth.

I'm not saying any of the above to attack mdiehl etc. I'm just trying to answer your question and explain why I engaged with him for so long. It takes a lot for me to pull the trigger on green buttoning someone because I think silencing someone's voice is a really terrible thing to do. Sometimes though we need to do such things to protect ourselves. I just want to be sure that I'm not green buttoning for too little reason and so I try to provide lots of opportunity to back down and say, "Oh, I misunderstood you" or find some other way to reach a livable compromise.


GAME STUFF:
Personally I wouldn't find that tactic gamey. In my current game my opponent did it to me a few days ago. We are playing with unlimited altitude and so he is free to send planes at any altitude he wants. He has chosen to send them in at 100 feet at night because that does the best job of preserving his force while destroying mine. IMO that's simply good play.

I DO think the model could do with some tweaking in order to better model the actual real-world likelihood that his bombers would achieve 60 or 70% hit rates with their bombs while flying at night over a darkened enemy airfield. With that said though he's making the best use of the forces he has given the current game engine. I am happy for him to do that. Of course the caveat is that then when I get really sneaky and do something similar back he had better not complain either [:D]

Different people view that situation somewhat differently though and would make a HR to limit night bombing to, for example, no lower than 6,000 feet in order to get the hit rate down to a level they believe is more historically accurate. Each to their own. I play it my way, I fully support their right to draw the line in a different place and play it their way so long as they enjoy that.


Obvert:
Small bombs are more effective because with 10 small bombs vs 2 large ones you are much more likely to hit and so overall you are more likely to cause more damage with 10 x 50 Kg bombs given the current to hit calculations by bombers than with 2 x 250 Kg bombs. If you get lucky and one of the 250 Kg bombs hits then you'll do a lot of damage BUT that depends on luck. If you are looking for some certainty and following the Soviet model in which they believed that x amount of fire on target y could lead to statistically predictable results then you will be happy to settle for more certainty since then you can say: With 2 x 250 Kg bombs 20 bombers MIGHT utterly close the field or they MIGHT leave it almost undamaged. Often they'll leave it damaged but still open. HOWEVER with 200 x 50 Kg bombs it is far more likely that they'll get enough hits to cause at least some damage and it is quite likely they'll do enough to close the field.

So, more bombs means more predictability in the result, fewer outlier results and a greater ability to confidently say - x bombers WILL close the field if I send then in at such and such an altitude.

That's a simplistic example and doesn't account for a lot of stuff but it is enough to get the point across and get people to thinking why the Ki-51 is such a wonderful strategic bomber in China, certainly better than the Ki-21 etc ;-)


|Re: LoBaron and night bombing.
I'm happy with "no rules games" on the basis that "if they do it to me I'll do it back to them twice or three times as hard" [8D]. I also like the way no rules games push me to come up with new tactical solutions to problems because the options are all available, limited only by my imagination, ability and game code.

With that said do I think a night bombing raid at 100 feet results in an unrealistically high number of hits when the DL is high? Absolutely. If you want a historical game I'd suggest limiting night bombing missions to no lower than 10,000 feet for twin-engineds and 15,000 feet for 4-engined bombers.

With that said in my game I've had to face night bombing raids by A6m7 fighter-bombers dive-bombing my airfields at night [8D] so, obviously, we're doing "whatever works" and not "whatever Japan did in real life" [8D]

Just as an example for the part I bolded, during the Cold War the Soviets had a mathematical algorithm to determine the optimum number of Backfire bombers to send on attack missions against USN CVBGs...enough AS-4s carried to ensure destruction of the carrier without 'wasting' ordnance. Very meticulous in their calculations they were. Of course it was all in theory, as WWIII never broke out (thankfully).

CoD, its getting better (slowly). But already passed IL2 in terms of complexity and looks, has a long way to
go to surpass it in content though and will take about half a year still to be called a game and not a "WWII
air combat model simulation with occasional gameplay flavor"...

http://www.youtube.com/watch?v=-dnobzWF ... re=related


Anybody with a halfway decent WWII combat flightsim knows the difference between shooting bombers and playing defensive gunners anyway.

Obviousely a fighter pilot got all the initiative, freedom of target selection, path of approach, choice of breakoff point.
The defenive gunner has to act passively, thats a major disadvantage. Wonder why this hasn´t been mentioned yet.

Does 420 mph airspeed restriction applies to speed of the attacking plane relative to Earth or bomber?

Nemo121

Thanks, i've sent you PM with my email.

As for MiG vs B-29's, a little bit more information from my sources - not to start any flame war, mind you, just to give a more clear point of view from the "opposing side" [:)] I've read quotations from 64 AK records in Central Archive of Ministry of Defence in Russia, that describe in detail which planes (with s/n and pilot names) where damaged or lost in 22-27 of october, 1951. In contrast to damage from fighters (many bullet holes along wings or fuselage), damage that was clearly identified as B-29 gunner hits boils down to 1-2 bullet holes in fuselage or keel; This fits the description from pilot memoirs, so I can assume that reliability of this data is quite high.

As for gunner claims, the pilots address this issue in their memoirs and interviews. Their suggestion is such:
as combat with B-29 took place only above North Korea, the only proof american gunners could have were gun camera shots. And as photo took place the moment the gun fires, it is difficult to estimate whether the target will be hit or not. Besides, as MiG's opened fire from long range, what could be presumed as hit sparks and falling debris would actually be muzzle flashes and falling cartriges.

Kramarenko, for example, presumes that he was claimed in such way at least several times during one battle. He was attacking B-29 and it's gunners shot straight at him. Shells where falling several meters lower, but gun cam photo should have shown a perfectly clear picture of MiG inside crosshairs.

However, they are making this assumption based on characteristics of soviet web cam. Perhaps american cameras worked differently?

The question makes it sound like I may have been unclear.

The FCS on the B-29 had difficulty tracking aircraft that were moving very fast. In excess of 480 mph (groundspeed) and it got really bad above about 500 mph (groundspeed). That is why, during the Korean War, it was incapable of fending off MiG-15s.

Advanced Japanese fighters were incapable of sustained level flight airspeeds in excess of 420 mph, and even then they only obtained these airspeeds in test conditions (there are a bunch of reasons for that involving harder use and maintenance under field conditions, and teething problems that caused high-pressure multiple-bank Japanese radials to perform suboptimally). Their optimum altitude band for that sort of thing did not reach to the operational altitude of B-29s.

"420 mph relative to the bomber" seems to confuse the two issues. Were you asking about the FCS or the Japanese engines? I hope my answer cleared things up a bit.

By the way. For anyone who enjoys watching gun camera footage, you should consider the way that fighters move when attacking bombers. In almost every film I have seen, the attacking fighters are rolling, pitching up or down, or yawing (applying rudder in level flight). Each of these imparts a momentum to the fighter's projectiles that is not along the direction of the bullets' main axis of flight.

Rolling was the most complicated situation. An interceptor attacking a bomber while rolling had to account for the fact that the effect on his projectiles' travel path was different for EACH WING of the interceptor if it had outboard guns. An interceptor while shooting in a right bank (rolling "clockwise" from the perspective of its pilot) imparted a right hand momentum to bullets from guns/cannons on the LEFT wing, and a left hand momentum to bullets from guns/cannons on the RIGHT wing.

Anyone who claims that the interceptor pilot's aiming task was less complex than the aiming task faced by gunners on any defending bomber is objectively and undeniably incorrect.

But mdiehl, it's quite a good question. If a fighter is moving 420mph but coming straight AT the bomber then the angular velocity (might not be the correct term as english is not my native language) is 0. Thus the FCS should have no problem tracking. In fact, the speed of the fighter shouldn't matter much, as the bombers own movement can produce results where the fighter is quite untrackable.

Sure. It just wasn't clear to me which question he was asking.
If a fighter is moving 420mph but coming straight AT the bomber then the angular velocity (might not be the correct term as english is not my native language) is 0. Thus the FCS should have no problem tracking.


OK. So, as Nemo pointed out, there are components to the velocity of a projectile that are not in the direction of the bullet's main axis of flight ... the path it would take if you shot it from a gun and you and your target were stationary. (He's wrong in his assumption that these components don't affect fighters targeting, for reasons I have described above). Both the fighter and the bomber have to account for the "angular velocity" (it is a good enough term for this discussion) not only of their own bullets but also of the target.

The FCS did that very well up to a point, by all accounts. That point seems to have occurred when facing a.c. with airspeeds in excess of 480 mph (airspeed over ground). I suspect that means that the combination of the computational speed of the FCS computer and the user (gunner) inputs was insufficient to deal with *deflection shooting* at jets. In effect the "targeting picture" was changing faster than the FCS could keep up. For enemy a.c. traveling at leas than 480 mph, the computer stayed ahead of the information cycle.

With very low deflection shots, which seems to be the case you just described, the approaching fighter was a much easier target because it was not moving much, laterally, relative to the shooter. I doubt that very many of those Korean MiG-15s, however, were willing to close with a B-29 offering low deflection shots. The Germans certainly avoided attacking much weaker B-17s during WW2 from low deflection situations unless they were sure that the target was already substantially crippled. (The ME 110-410, series, for example, was so vulnerable to B-17 defensive fire that their standard A2A doctrine for attacking B-17s was to stand off out of cannon range and lob rockets at B-17 formations).
In fact, the speed of the fighter shouldn't matter much, as the bombers own movement can produce results where the fighter is quite untrackable.

The bomber's own movement complicates the situation a little, but not to the point where the fighter is even remotely untrackable. Not even if the person shooting at the fighter is a B-17 gunner. On the B-29, however, the FCS took input from the B-29, and from a couple of gyroscopes, that accounted for the B-29s unanticipated lateral motion. And the gunsight used to target the interceptors was itself gyrostabilized, so that it did not seem to "shake" when centered on an approaching fighter, no matter how much the bomber moved.

So, yes, "noisy motion" on the part of the bomber could affect bomber targeting. But on the B-29, the FCS corrected for that noisy motion (and also forward airspeed, lateral motion imparted as the turret traversed, etc) gyroscopically.

I've been reading this bbs for years.  I've seen mdeihl waste hours of his life calmly explaining his arguments.  He's a good man and knows what he's talking about.  His posts are always interesting.  I enjoy reading them.

Terminus, you suck cocks don't you?  I've seen you bashing everyone, even ppl who are new and just asking a question.  On and on w/ ur stupid nonsense.  Ur a dick.  I bet ppl who know you hate you.

Um, hrrm, thanks for the compliments. Don't give a thought to Terminus. Please.

And come on back to the Drivethru. Everyone there wants to say "hello!"
Show me a fellow who rejects statistical analysis a priori and I'll show you a fellow who has no knowledge of statistics.

Didn't we have this conversation already?

Bah I shouldn't have posted that.  I get fed up. 

I'd rather read the prating of a little girl instead of Terminus.  The guy's a bitch.  I'm sick of him.
