    There were 1000 lbs, 1600 lbs (if I remember well) and 2000 lbs used the Americans.

    not just those..........

    RAF bomber command used 4 main types of bomb during WWII, these were the GP (general purpose) bomb in the early years, but was not very effective and so gave way to the MC (medium capacity) bomb, HC (high capacity) and Incendiary, which some would not class as a bomb but the RAF classed as a "Fire Bomb"...........

    The GP bombs were baisically the same as WWI bombs but bigger, they saw very little success despite extensive use, they came in 40lb, 250lb, 500lb, 1000lb, 1900lb and 4000lb, the latter two seeing very little use. None of the bombs had any better charge-to-weight ratio of 34%.

    The Incendiaries were filled with Thermite pellets or a mixture of phosphorus and rubberised Benzol. At the start of the war the incendiaries made up about 6% of an average bomb load however when their effect was started to be realised they were used increasingly more and during the war this rised to anywhare up to 66% of a payload! They existed in 4lbs, 30lb and 250lbs.

    These were then joined by the MC range, which replaced the old GP range. The MC range came in 3 sizes, 500lb, 1000lb and 4000lb and all had a charge-to-weight ratio of 50%, these were the most widely used bombs in bomber command, in particular the 1,000lb as 256,500 were dropped from 1943 to '45

    Then came the HC bombs. These came in 6 sizes i believe, 500lb, 1000lb, 2000lb, 4000lb, 8000lb and 12,000lbs. The 8,000lb and 12,000lb were essentailly 2 or 3 4,000lb bombs bolted together. The 12,000 HC bomb IS NOT the tallboy, it is a different bomb. These bombs had a charge-to-weight ratio of 70%! the most powerful of these bombs were filled with Minol.

    Also used by Bomber Command were a range of Specailist bombs, but the only ones used as standard was the Tallboy so i shall only speak of this one. She was, along with her big sister the Grandslam, classed as a "earthquake" bomb, very streamlined so that during the fall she exeeds the speed of sound and penitrates deep into the ground, when she detonates causing an "earthquake" effect. Over 800 were dropped operationally.

    Also at one point during 1944 RAF Bomber command had to use American 500lb and 1,000lb bombs due to a shortage of their own, however these were not liked as their square tails meant not many could be carried (all British bombs had circular tails and our bombers were designed with circular tails in mind).

    i hope this's helped, sorry i can't help with American bombs, there's a lot i couldn't be bothered to type so if you've got any more questions just ask, and remember i've only covered the major bombs, a lot of other, very important bombs i haven't mentioned because they are not standard.

    USN/USMC ordnance deliveries were, for carrier-based and land-based aircraft, bomb type / number of bombs / tonnage / % of total tonnage (not including 1944 land-based results which are not available):

    500 lb. GP / 91,776 / 22,944 / 29.7%
    100 lb. GP / 294,380 / 14,719 / 19.1%
    250 lb. GP / 100,776 / 12,597 / 16.3%
    1000 lb. GP / 18,100 / 9,050 / 11.7%
    2000 lb. GP / 4,907 / 4,907 / 6.4%
    500 lb. SAP / 11,384 / 2,846 / 3.7%
    250 lb. Napalm / 15,864 / 1,983 / 2.6%
    1000 lb. SAP / 3,632 / 1816 / 2.4%
    2000 lb. Torpedoes / 1,605 / 1,605 / 2.1%
    260 lb. Fragmentation / 10,472 / 1,309 / 1.7%
    250 lb. Depth Bombs / 8,296 / 1,037 / 1.3%
    250 lb. Other Incendiary / 9,690 / 969 / 1.3%
    200 lb. Mines / 5,260 / 526 / 0.7%
    500 lb. AP / 1,772 / 443 / 0.6%
    Unknown / n/a / 397 / 0.5%
    TOTAL / 577,914 / 77,148 / 100.0%

    USN/USMC rocket expenditures were 555,670 for 1944 and 1945.

    Oh, not without a lot of digging . . . and I try to stick to Naval Aviation when I can.

    Seriously, I just had some guys in today putting in new wall-to-wall carpeting and all my resources are stacked in the garage . . . behind the furniture. I suspect it will be several days before I can get to them.

    Sorry.

    This info is great! Thank you all for posting it.

    One thing that I would like to say that I do believe that the Russians used a 5000 kilogram bomb when overloading the PE-8 for short haul missions (Unless I am mistaken, of course) and I also believe that 1600 lbs bombs were indeed used by the USN and USAAF, although I'm entirely sure what was the frequency of their use or other specification of how much explosive they had relative to their overall weight. If I find any more information, I'll post it here.

    Thanks once again for the info about the German bombs, I've been wondering about them for quite a while now.

    For the German bombs, for the most part the number in the designation of the bomb denots the weight. For instance the SB2500 is a 2500kg bomb or 5511,5 lb bomb. I also believe that is the heaviest bomb used by the Germans.

    Salim -

    Interesting that you indicated that the Americans used 1,600 pound bombs. That's what I was trying to confirm.

    Does anyone else have any information on bombs betseen 1,000 and 2,000 pounds?

    the only British bomb between those weights was the 1,900GP bomb, which saw very limited used due to fusing problems and the fact it kinda sucked :lol:

    You should check this link out.

    http://home.att.net/~jbaugher2/b25_17.html

    It mentions 1600 pound armor-piercing bombs in the third paragraph, as well as later on in the article.

    I also believe that the SBD dive bomber could also carry a bomb that big, but I'm not sure just how frequently they did it.
