The "gold standard" of data used to project abilities in the game should be "Allied reports say they launched an attack on x with y forces, and reported z losses by the Japanese while sustaining q losses" corroborated by "Japanese forces defended x with a forces and lost b while inflicting c losses upon the Allies". When you compare the reports, I'm inclined to believe the q and b numbers, and not the z and c.

Just gimme a $500,000 research grand and I'll report back to ya'll in 3-4 years...[:'(]

Show me a record if IJN losses in the areas hit by B-17's on the dates mentioned, and we can extrapolate from there to it's actual performance. Right now, I can't credit any hits to B-17's because the cases where it that information is available come down to one: the DD Mutsuki, which was stationary.

There was another hit by B-17 on destroyer during Guadalcanal, although not lethal. I'll dig for exact information. I don't think that anyone here tries to say that level bombers are good in anti-shipping role. But should they have to have a chance to hit something from time to time? I think Yes. And it works for both sides. Some of the G4Ms harassing Guadalcanal were in fact using bombs not torpedoes and achieved hits on moving targets. Don't remember the name of the APD sunk, unfortunately.

As WitP works right now it's a number of bombs, experience and altitude. I'm pretty sure if I start using B-29s on 1000 ft naval strikes I will obliterate all the shipping encountered.

I agree. I don't believe that the chances should be nil, but dive bombers only achieved a 20-25% hit rate in the best of situations, LBA should be worse given that they are both less manueverable and generally dropping bombs from higher up. AA intensity, the presence of CAP, weather/clouds at the target, target speed and size, aircraft manueverability and speed, bomibing method (glide/level/dive), pilot skill, and fatigue should all impact the hit probabliities. So far, the overwhelming influence on hit probability seems to be pilot skill and number of bombs - to the point were LBA seems overpowered compared to DB's.

An excerpt from http://www.history.navy.mil/photos/even ... mid-4d.htm :
"Then, somewhat after 0800, fifteen Army B-17s struck, raining down sticks of bombs from high altitude. Much was expected of this kind of attack, but no hits were scored, a result that further war experience would demonstrate was all-too-typical. On the other hand, the "Flying Fortresses" were little damaged by Japanese anti-aircraft fire and fighters. They made several fine photographs of the Japanese carriers maneuvering far below, an indication of the true role of these heavy bombers in contemporary maritime warfare: long-distance reconnaissance by aircraft capable of defending themselves."

Contrast this view with the following combat narrative describing the effects of the B-17's attacking IJN CV's from http://www.ibiblio.org/hyperwar/USN/USN ... ay-10.html :

You will note that
"At 0900 Lt. Col. Sweeney had reported that the B-17 attack was completed and one enemy carrier had been damaged."
"Consequently, it was decided to attack a heavy cruiser. They reported that at least one hit was scored, and the ship was left smoking heavily. A transport was also attacked, with unobserved results. "
"Bombing from 9,600 feet, the B-17's reported that they hit a battleship twice and dropped two more bombs on a damaged carrier."
"The Fortresses reported that they scored a hit on a damaged carrier and on a destroyer and strafed the decks of several ships as they passed. "

Had I been given reports indicating damage to carriers, BB's, and CA's as the report above indicates, I would continue to send them out on attacks against naval forces too.

I agree 100% with you. We have a game here, besides historical accuracy there is always an issue of the game play balance.

The thing is that they were bombing from 10,000 ft. In WitP level bombers flying 10000 ft will rarely hit anything. We bring them down to 1000 ft, so software adjusts probability accordingly, altogether with morale penalty, op penalty, and flack effectiveness.

We decide how to use bombers, WitP just calculates the results. There was a huge tread with testing of level bombing against shipping. Results were statistically refined.

Everything narrowed down to the number of bombs on board. B-29 was an absolute ship-killer. Reducing bomb-hit probability would've made IJN bombers totally impotent, because they already have small number of bombs (i'm talking here not about individual device hit probability, but about formulae calculating individual hits on ship). CHS guys reduced bomb load of allied level bombers. Looks like it works so far.

Be advised that you can only score one hit on an enemy ship with LBA. WitP considers the drop such that no more one bomb will hit the target (reasonable).

Now, how it considers the stick is important (and unknown).

Does it roll for each bomb, until one hits? You'd have several rolls for a hit, but only one hit can be scored.

Or does it roll once for the entire payload? Thus one roll, for a max of one hit.

Dunno what it does.

I think that it is an individual roll for every bomb until one hits. Although only developers can answer for sure.

Back in UV days the code was changed to allow 1 bomb per LB when attacking ships but this does not appear to be the case anymore from what i have observed. I have seen 3 bombers for example, score 4 hits. I have reduced heavy bomber loadout by 50% and seen a drop in hit rates at sea by the B-17's

Well that would certainly be an issue.

While I still maintain that B-17s and 24s were not as inept as some would claim, the arguement remains completely anecdotal for both sides (esp when considering that they wouldn't believe a hit report anyway; the entire "discussion" becomes moot).

However. If what you say is true, that you can score multiple hits with Heavy Bombers (or Mediums for that matter), that would be a serious issue. Not only does it mean that you can get multiple hits, it means that the probability of getting that single hit, is caculated by multiple rolls, instead of one roll for the entire drop.

While I -can- imagine B-17 or B-24 crew attacking a TF at 6000' or 12000', and dropping their stick all at once; I -cannot- imagine those same crews pickling out their bombs one at a time in multiple attacks. That would definately be a problem.

I imagine that most types of a/c would be fitted with 'all or nothing' bomb release mechanisms anyway.

I know that various a/c could drop a partial load, but I doubt that most could. The only examples of partial load drops that I can think of are the Doolittle and Dambusters raids, but I'm sure there were some a/c that did this as a matter of course.

I just doubt that B-17's, etc. had this equipment (for partial drop). I wonder if this ability was one of the modifications for the naval version of the B-24 (I think it's called PB4Y)? Anybody know?

Actually the B-17 could drop bombs in increments and it was done occasionally but it was not the usual practice. A problem with LB's getting too many hits is that the default loadouts represent maximum loadouts and are standardized. In real life, especially early war, the 17's went out with a variety of munitions and quantity levels. in the game its always a standardized load based on max capacity.

Yep. The interviews I've read, said that the B-17s and 24s (and likely most bombers), had a "salvo" switch, that allowed them to drop them all at once or in some weight approate pairing or singles. In the case of 17s and 24s, salvo was the far more common usage.

I was actually talking about a formation of B-17s lining up and pickling out one bomb. Then turning around, and making another run on the target. The turning radius of a B-17 is measured in -miles-. Executing a maneuver like that in formation would be very dangerous. That's to say nothing of the fact that the Flak at the target will be that much more intense.

Well, I thought this was interesting. This is an account of skip-bombing mission by B-17s of the 43rd Bomb Group (taken from a diary). Evidently, they did "pickle them out" one at time (in this case at least), and on this mission made 5 runs on the target. And on this mission, 7 B-17s managed to disable to 2 destroyers (might well have been PGs in game terms, who knows).

Interesting reading tho...

By 24 November 1942, when the 65th Squadron knocked out enemy gun positions at Sanananda Point in support of ground forces, the entire 43rd Group had been committed to combat. On that same day the 63rd Squadron attacked enemy shipping in the Huon Gulf. The dangers involved in those shipping strikes, not to mention the skill and endurance of the aircrews is clearly illustrated in the following account. Just before midnight on 24 November, seven B-17's of the 63rd Squadron --five of which had participated earlier that day in two missions aimed at supply dumps at Sanananda Point-- took off to attack five enemy destroyers reported in the Huon Gulf. After spotting the ships, the planes climbed to 3,500 feet, then dropped to 200 feet to make their first run. At that point antiaircraft fire bursting around the planes penetrated the tail gunner's post of the B-17 piloted by Captain "Ken" McCullar, exploding "about 70 shells and starting quite a fire." Sergeant Reser, the tail gunner, succeeded in smothering the flames with winter flying equipment. McCullar made a second run. That time the radio operator and two other members of the crew were scratched by flying shrapnel. On the third run "the number 1 motor was hit and all controls shot away." The fourth run brought only minor damage to the plane, but as the bomber sought out a target for the fifth time, number 3 engine sputtered and finally "cut out." By now, one destroyer was burning fiercely and another was seriously disabled; so with the bombardier and navigator in the back compartment of the ship "in case the prop flew off or we had to set it down," Captain McCullar fought for sufficient altitude to clear the Owen Stanley Mountains. Fortunately, number 3 engine began to function again, and after two and one half hours, according to the pilot, the crew "found a pass to sneak through, landed o.k. and forgot about it."

I've done a little investigating on the issue of heavy bombers vs ships; specifically IJN destroyers. Checked out the IJN DDs at Combined Fleet.com one by one. Only Mutsuki's Record of Movement specifically mentions 'death by B-17'. There are 5-6 others that specifically cite 'death by B-26/B-25 and a then another 3-4 citing 'death by unspecified Army bomber' and then a dozen or so citing 'death by air attack (NFI)'. THE PART I LIKE BEST IS THE FACT THAT ALMOST ALL OF THEM HAVE SOME KIND OF 'DEATH CERTIFICATE'. Anyway, it occurred to me that neither the IJN "Ban the Bomber (B-17)" types nor the Allied "CAN TO" types mentioned the Battle of the Bismarck Sea.
Checking out several accounts there are claims and then there are claims and the records are confused but it appears that the following occurred:
1) On the first day (3/02/43) the majority of the anti-shipping strikes were carried out by B-17s and B-24s with the light and medium bombers making supporting strikes on local IJA/IJN airfields. Several transports were so disabled that the IJA troops were offloaded onto DDs and transported to Lae thereon that night with the DDs rejoining the main convoy by morning. The next day B-17s/B-24s/Beauforts made the initial strikes. The Beaufort torpedo attack appears to have been completely unsuccessful. Two IJN DDs: Arashio and Tokitsukaze were hit and got hurt bad by the heavies: didn't sink but they were unmanueverable when the B-25s/A-20s made the 3rd strike of the day (skip-bombing); arguably the most successful anti-shipping strike in history. Although the strike was crippling for all the transports and half the escorts there were continued strikes for the remainder of the day and into the next that finished off all the cripples.
Final Score:
IJN: 3 fighters, 2 bombers shot down, many a/c damaged
USAAF/RAAF: 4 DDs, 8 AP/AK sunk

OT: Oh by the way; 2 IJN DDs show cause of death as being running into minefields while manuevering to avoid attack by PT boats.

Actually, i'm quite familiar with the Battle of the Bismark Sea. Launched in fact by "Ken's Men" of the 5th Air Force, including the 43rd Bomb Group. They struck the convoy first, with 17s, logically because of thier range. Initialy strikes by something like 18 heavies, and damged 2 ships. THey were the 1st strikes, so no question that the heavies clobbered the first ships. More air attacks for about 3 - 4 days in March(?) vs. a Japanese convoy of about 8 transports and 6 escorts. A-20s, P-38s, and B-25s. Lots of them. Clobbered the whole thing, and 12,000 IJA went down with it.

But that's just the top of my head...

[;)]

But if I had posted the Bismark Sea, it would be written off as, "Bah. Just another convoy attack. Nobody knows who hit what. Why did it take 150 aircraft to sink just 14 ships." Blah. Blah. Blah.

It was in fact a major victory for the the 5th AF, and essentionally sealed the fate of New Guinea. But in WitP, you see mega-convoys landing 4 Divisions. So a "paltry" 14 ships and 12,000 casualties are nothing.

I also find it amusing that, according the debriefs, skip bombing was considered great for INEXPERINECED crews to be effective vs. shipping. Not the elevated 80 exp like you see in WitP. It was in fact, exactly opposite in real life, than what we see in WitP. But imagine the wailing and gnashing of teeth if you made skip bombing MORE effective, by allowing crews with exp in the 50s to be effective at it. [8|]

If you're interested tho, a very good site (including considerable documentation), is

Sorry to say that, but all the sinking reports and the bismarck sea operation were carried out by low flying planes. The initial rant was about B-17 bomb hits from 15000 ft. or something and so far I've seen no proof that in the whole war there was just one of those hits on a moving ship.

Morning of Aug 19, 1942. Kagero, Hagikaze and Arashi were shelling Tulagi.
While they were thus occuppied, three (!!!) B-17 passed overhead releasing sticks of bombs. Three of these (bombs?) scored direct hits on Hagikaze's stern that killed 33 of her crew and wounded 13. Tanaka ordered her to withdraw from the area under escort of Arashi; Kagero remained to watch the area...

Very nice report but what altitude were those B-17 passing overhead ?
I am not questioning that when level bombers fly low that they can score hits. I'm questioning that when level bombers stay high up (outside the reach of puny IJN AA) that they can score the hits they seem to achieve in the game. There have been lots of misson reports posted so far but most lack altitude descriptions.

As much of a heavy bomber fan-boy as I am, I readily agree that the accuracy of the heavies is over-stated at altitude. What gets my gall up is
a. People insinuating that heavy bombers never hit anything, and should not be allowed to be set for Naval Attack. Utter non-sense. They were used in the anti-shipping role frequently, and hit their targets with a success rate that warrented keeping in that role for 12 years.
b. Those same people whining about heavies, have no problem with the fact the Betties and Nells are completely unhistorically represented. I am more than happy to have an intelligent disucssion with somebody who can be objective about the the situation. I will readily admit that the heavies are are more accurate than historical. But the detractors want to completely eliminate their anti-shipping ability, and at the same time indicate that nothign is wrong witht the portrayal of Japanese LBA in WitP. And when I produce a plethora of historical documentation, and others simply say, "I don't believe it." Oh well. Discussion is over. For those that choose to be ignorant, I won't waste my time.
c. If the accuracy of heavys at alt is to be reduced, I'm all for fit (believe it or not). But if you do that, please improve the portrayal of them a low altitudes. Make skip-bombing accessable to where it is an accurate portrayal of history.

I compeltely understand that there are two schools of thought here.
I. I am of the school that wants a realistic wargame, that harkens back to the card-board counter days. That offers historically accurate protrayals. The game can end up going in any direction, whether it's a compelte reversal of Midway or whatever. But everythign that does occur, should occur within the framework of what was historcially POSSIBLE.
II. Then there are those, that want WitP to play out like "Axis & Allies". Let's romp thru history with our "uber-iffic" KB +3, and blow the crap out the Allies.

I'm not a moderator (on this board) but I have to comment that stating that one is interested in a objective, thoughtful discussion, then turning around and implying that anyone who doesn't agree with your view point is not interested in a historical game is contradictory, not to mention insulting.

Just a thought. Not trying to pick on you F. [;)]
