    Johnny Walker Bomb

    Who has technical information about the (500 lb.) Johnny Walker Bomb.

    I have the info from the book "Bombs Gone, the development and use of British air-dropped weapons from 1912 to the present day". By W/C John A. MacBean and Maj. Arthur S. Hogben.

    These underwater "walking" bombs/mines has been used against the German Battleship Tirpitz on 15 september 1944.

    Antoon,

    I have quite a bit of info on the JW bomb, I just can't find it at the moment! Attached is a photo of one. Where was your photograph taken?

    Regards

    JW Bomb

    You will know from Arthur's book that MD1 produced the JW Bomb (in two marks). MD1 was headed up by a Royal Engineer officer Millis Jefferis (MJ). Attached is one of his sketches for the operation of the Oscilating Mine known as Johny Walker.

    Plumbing rather than ordnance!

    Very good Photo and sketch guys.

    My photo is taken in the Armed Forces Museum (Forsvarsmuseet) at Oslo, Norway.
    Parts of these bomb have been found by Norwegian EOD on the mountain slopes of the Kåfjord.

    Some info says that the ordnance that was used was named “400lb. JW Mk II Mine”. Is this correct, because other sources say 500 lb. And what was the official name?

    Antoon,

    The full description in the handbook is;

    "Bomb, H.E., Aircraft, J.W., 400lb. Mk.I"
    or short "J.W. Bomb"

    Although it weighed in at about 400lb the filling was 90lb Torpex.

    Do you know if there is a fuze with the specimen that has been recovered?

    Regards

    Tim.G.

    Thanks for the info.

    I do not know if they have recovered the fuze.

    What is the title of the Handbook you mentioned?


    Greetings - Antoon
