US 10 000 LB bomb

"What the pictured bomb stenciled as 10,000 lbs is the question, but it isn't a 4,000 lb one.''

Believe what you want to.

My question is. There are many, many pictures of what you claim is both your 10,000 pound bomb and the 4,000 pounder all over the internet.

If it turns out that what I have known to be the ANM-56, 4,000 pounder and are rather your 10,000 pounder....

I ask the following: Where are all of the photographs of the much utilized, standardized ANM-56?

While you think about that, look at the following image of these people crawling around on 2,000 pounders.

Reminder. The above pictured 2,000 pounders are GP heavy, forged cases, where the ANM-56 is a light case of welded construction.

The 4,000 pound, ANM-56 is more than twice the size of these 2,000 pounder.
 
Here a nice picture of the 4000 lb, a good idea of the size

According to Commando Vault project report (easy to find in internet, e.g. http://preview.tinyurl.com/mmncvj9) "The M121 was approximately 9-1/2 feet long, nearly four feet in diameter, and weighed 10,800 pounds, of which 8,050 pounds comprised the explosive agent, Tritonal". There are probably warhead data, without the tail fin. In metric this is approx. 2,9 m length, 1,2 m diameter, 4900 kg total weight, 3650 kg explosive weight (74,5%).

M56 (AN-M56) LC, 4000 lb (from TM-9-1980): total length 117,3 in (298 cm); body length 94,9 in (241 cm); diameter 34,3 in (87 cm); total weight 4368,8 lb (1982 kg); explosive (tritonal) weight 3526,3 lb (1600 kg).

For comparing, American Tallboys data (from "Very heavy conventional aerial bombs", article by John Godwin, years ago found in internet).

Bomb, GP, 12,000-lb, M109 (T10) - Tallboy M, or simply Tallboy equivalent. Total length 252 in (640 cm); body length 124 in (315 cm); diameter 38 in (97 cm); total weight 12622 lb (5725 kg); explosive (tritonal) weight 5500 lb (2495 kg).

Bomb, GP, 22,000-lb, M110 (T14) - Tallboy L, or Grand Slam equivalent. Total length 305 in (775 cm); body length 150 in (381 cm); diameter 46 in (117 cm); total weight 23037 lb (10450 kg); explosive (tritonal) weight 9600 lb (4355 kg).

Bomb, GP, 42,000-lb, T12 - Cloudmaker. Total length 322 in (818 cm); body length 200 in (508 cm); diameter 54 in (137 cm); total weight 43600 lb (19780 kg); explosive (tritonal) weight 17600 lb (7980 kg).
 
For those who are interested in the geographical location of the AN-M56, 4000 pound bomb.

As of right now, this ONLY APPLIES to BING MAPS * * BIRD'S EYE VIEW * *.

The AN-M56, 4,000 pound bomb is located in Oshkosh, Wisconsin, USA.

It is and/or was located within Wittman Regional Airport.

There is a closed runway #4 that runs south/west to north east.

On the south/west corner of runway #4 there is a white roofed "L" shaped building that the ANM-56, 4,000 pound bomb as well as smaller casings can be seen.

If anyone can find the ANM-56, 4,000 pound bomb's current location, do tell.

Here is a bit more homework.

Note. The woman is slightly behind her casing, where the man is slightly ahead of the casing.

Notice that the on the vintage casing, " 4000 " can be seen.

More nails in the coffin.

Notice points "A" and "B".

Had I noticed, I could have lined up the fins in the recent and vintage images almost perfectly.

just got an email from the place who has the bomb, their ,measurements meet up with the 4000 lb'er - man enough to admit when I am wrong - thanls for the info. But still looking for M 121 spec's and pictures - sorry for the rambling on
 
Seriously, you contacted them?

Good man. Thanks.

Now someone needs to get on them about replacing the weight on that casing before history repeats itself.
 
they ahven;t returned my email telling them the bomb is labeled wrong yet, in their email they said it was dropped from a B 24
 
I have verified that the Consolidated B-24 ''Liberator'' did in fact have the ability to carry two 4,000 pound ANM-56s. One bomb under each inboard wing on a special mount.
