The 800Kg AP Bomb

[Chris21wen]

Does anybody know what Japanese A/c use it? In my PBEM game I've sunk an allied sub with one but I can't find which A/c dropped it?

[wild_Willie2]

800KG bombs are used by all japanese torpedo carrying AC on port attack missions....

[Q-Ball]

They are also used by Nells/Bettys flying from lvl 2 and lvl 3 airfields on Naval Attack.  I prefer Torps, but it's sort of an interesting trick to keep a lvl 3 AF around if you want to drop 800kg bombs, which can hurt anything including a BB.

But mostly, I have seen them used on Port Attacks. 

[John Lansford]

Too bad the Allies don't have anything comparable; the 1000 lb AP doesn't penetrate any deck armor heavier than a light cruiser's.  I saw them bounce off both a Nachi CA and a Kongo's deck armor without doing much more than scratching the paint.

As a matter of interest where is this info. All I can find is torps for Nells/Betties the same goes for most A/c, just the normal load.

I have NEVER seen torp bombers (Nell, Betty, Kate,...) using 800kg AP bombs on nav attack! If you see this happen then it seems there´s something wrong or it´s a special mod. Those bombers should use 250kg AP bombs on nav attack!!! Only on port attack you should see 800kg AP bombs instead of torps being used.

[John 3rd]

The kates use them at Pearl Harbor.  I have seen them dropped by 2EB in Australia too...
 

[jumper]

800kg bombs replace torpedoes during port attack missions (I think there is only 25% chance that bombers will carry torps). You should have 800kg bombs only if all conditions to carry torpedo are met.
 
For Betty/Nell it means at least lvl4 AF and normal range. For Kate it means lvl2 AF and normal range etc..

[Japan]

Yes the 800 KG Bombs are nasty,(in lbs its 1760 Pounds)  -   And for Ship Killing its a Great Bomb.
In real world, many of the KATES used this bomb instead of Torpedos, as the AP bomb from the VAL had limited effect, However the 800 KG AP bomb did not have limited effect lool
 
So in AE, thay will make the Carrier Operations ect alot more realistic, we can for sure expect the KATES to use the 800KG to larger extent.

Hmmmmm..... I seem to recall that the 800KG bombs used at Pearl were special. They were converted BB shells; made specifically for battleship row targets.

If so, I can't imagine that the Japanese had hundreds or thousands of BB shells just laying around waiting to be converted into aircraft delivered bombs. BB shells are expensive to make; machined to tolerance for the barrel, while a standard AP or GP bomb requires far less quality control during manufacture.

I don't have any facts or figures, but it would seem to me that after Pearl that these would be somewhat restricted in availability and use. Quite willing to be proven wrong here -- but something doesn't ring true when flocks of aircraft are carrying them later in the war.

There are FAR TOO MANY 800kg AP bombs used in stock WITP and I seriously hope NOT to see any more in fact I hope to see far less of them being used (none at all should be used, except at the Pearl Harbour attack). Those bombs were converted BB shells and IIRC only used for the Pearl Harbour attack. What we see in the game is something that never happened and shouldn´t happen. The Kates should use the same bombs as the Vals when on port attack. On naval attack they shouldn´t use the 800kg AP bomb at all as they would hit nothing when employing this bomb against a moving target because they have to drop it from a height where it is doubtly that they would hit a moving target.

Sorry Sir, but when you say "in AE, thay will make the Carrier Operations ect alot more realistic, we can for sure expect the KATES to use the 800KG to larger extent" I wonder in which world you are living? Saying that as a Japanese fanboy.

[Panther Bait]

As far as I know, not all of the Japanese 800 kg bombs were modified BB shells.  The initial ones used at PH were, but there were other versions of the 800 kg bomb designed after that.  However, I'll admit that I have no idea how many of these were actually produced or used IRL.

[Zakhal]

Players should have the ability produce these babies if they wish. I mean they can produce airplanes but not bombs for them? Doesnt make any sense at all. [:D]

TME-1985-5, lists several No.80 bomb types, both AP , and GP(HE), the 800 kg bombs used at pearl were special in the since that they were from a limited production run (modified Shels), but the Japanese built scades of these with configurations that met or exceaded the capabalitys of the ones used at Pearl.
 
 Prety Much All Japanese Carieers also had magizine storage space aloted for the types in this weight range.
 
 Research as shown that (Original Japanese load charts for the atacks) Port atacks in Austrailia, Java,Ceylone, and Pearl all used the 800 kg bomb type, in fact the exception to the rule was Pearl, because only their did the Japanese use torpedos and 800 KG bombs, during a port atacks.

The Kate weapons system and its torps and 800kg bombs were important for the Japanese for a reasion that might be unkonw to some, the Val and its primary weapon the 250 kg bomb Type (s), was not originaly considered by the Japanese as suficient for dealing with Allied CA's or larger war ships, the Japanese felt that the 250 KG bomb would not dispatch such a ship*, and the torps or 800 kg bombs would be nescessary to deal with them. After the Sinking of the Cronwall and Dorsetshire in the IO by Vals they changed their tune somewhat, but this explaines the proment placement of the 800kg Bomb type in IJN operations and Magisines.

....................

Something else to consider is that the 500 kg weight class is totaly absent from stock, and in a pinch Vals could manage to get one aloft, and Judys could as well. Nells droped them on the PoW and Repulse and got penatrations.

In PacWar (and thus I assume also in stock WitP) the 800kg bomb was inserted as an alternate weapon for very experienced groups. Any group 80 experience or greater had a chance to carry them, and the higher your experience was the greater the chance. The US was given the 2000 pounder, and I have seen a few fall in this game, although very rarely. But then I dont often see 90 experience allied air groups.

[Japan]

The 800KG APPIA1 (The Standard 800KG AP) was produced in large quantety, and used by sevral aircrafts. The Bettys who did not have Torpedo mounts, instead used 2x 800 KG AP Bombs.   This is a total Bomb Load of 1600 KG   (3500 Pounds).  ONE of the Torpedo Alternative was the IIHI-2A who had a weight of 1719 KG or (3780 Pounds), I think thay used this on a Aircraft, not fully sure tho...   

I know there was alot of vertions of it, but the Standard (APPIA1) was serialproduced for use on multiple aircrafts, the Kate, Betty, Helen, Peggy, ect. and more types had it.  Evan the Japanese 4E Strategic Bommber (Liz) had mountings for it, evan tho thay produced the Liz in few numbers, and decided not to serial produce it due to the high engine costs. (Something i hope we will be allowed to decide if we also think its to expensive to make..) 

So the Standard 800KG bomb is not so rare... the special vertions of it im sure is nother story. 



ADDITIONALY - CHEMICAL WEAPONS and HIGH EXPLOSIVE , the 550 KG (1200 Pounds) Bomb should be included in AE, this was used in great quantety, evan by the VAL! if Target Range was closer. Additionaly thay had a HE vertion and a CHEMICAL VERTION of the 550 KG Bomb, this two bomb types was both developed and tested in Mansuko, and used aiganst China as well as in Close Air Support Role. The CHEMICAL WEAPON (BOMB) was produced in large quantety, and used hevely in China as well as some in Burma.



Today Japan helps China to clean huge areas in China, to remove the remeinding Chemical Bombs put there by Japan during WW2, to read more about this see here: http://english.hanban.edu.cn/english/2003/Dec/81536.htm

I've had a couple of AKs eat 2000 lb bombs dropped by the B-18 Bolo group on Cagayan vs the AI. They do drop and they pretty much are1 hit = 1 kill on anything smaller than a CA.

[Dili]

I very much doubt that Betty's could get 2x800kg in bomb bay.

lenght:

TYPE 2 NO. 80, MK 5 (AP) Lenght 2,87m

HE, NO. 80 LAND Lenght 2,87m

HE, NO. 80, ORDINARY MODEL 1 2,83m

HE, TYPE 3 NO. 80, MK 31 MODEL 1 2,87m

HE, TYPE 99 NO. 80, MK 5 2,43m

And what about ARMOR-PIERCING, TYPE 2 NO. 150, MK 5 (1,496.88 kg) [:D]

[Japan]

Thay did not get them into any bomb bay as far as i know.

On WW2 By Thems its on Taxi, and the Bombs are sitting on the outside of the Aircraft Bodey.
Each of the 2 Bombs are 813KG - who totaly is a load on 1600 KG.  Load wise its not a problem, the Torpedo it can carry has weight 1700 KG. Im not sure if this is the standard or not tho..


EDIT: Sorry, I think the Torpedo was 1100 KG and not 1700KG.
