    Default bomb load abbreviations

    Hi,

    in a ORB entry concerning a raid on 11./12.6.1943 the following is written about the bomb load:

    Load 1x4000 lb. H.C. 30x4 lb. 'X' inc. 48x30 lb. inc.

    Can anybody tell me what the 'X' stands for?

    And another one:

    2/1000lb. G.P. (A/C K.M.P.L. and N Long Delay, remainder G.P. TD.o.o25) 7 S.B.C. (90x4lbs)

    What does in this case "A/C K.M.P.L." "N Long Delay" and "G.P. TD.o.o25" mean?

    Thanks for your help.

    Best wishes.

    Marcel

    Hi Marcel. Just guessing here but might it simply mean the the squadron's aircraft with the code letter 'K', 'M', 'P', 'L' and 'N' were to be loaded with that particular bomb load or type of bombs (long-delay fused)? Ian

    Hi Ian,

    ok, that seems to be correct, because all these aircraft with this codes participated in this raid, thanks.

    So the question is left, what "G.P. TD.o.o25" and the 'X' meant.

    General Purpose ....???

    GP is normally General Purpose. TD I suspect is time delay but I'm not sure what o.o25 is. A guess would be 25 seconds or .025 of a minute, the first .o. being the hours or even whole minutes.

    I think it's 0.025 seconds (time delay before detonation). GP is General Purpose.
    ps That was only a guess, so I'm happy to go along with Finn (below) if he knows better!

    Hi Marcel

    This must be the answer of the abbreviations in your ORB.

    H.C = High Capacity Bombs (of thin-walled, "boiler plate" construction)

    Inc. = (I.B.) Incendiary Bombs

    X = A Tetryl explosive charge is indicated by the letter X

    S.B.C = Small Bomb Container

    TD.0.025 = Time Delay 25 sec.

    ----------------

    Hi ianh

    The source is reliable and published in USA in 1946 under the title "British Explosive Ordnance".

    Kind regards
