    daisy cutters

    I remember from Vietnam the air force would put pipes extensions on the front of some 250-500- and 750 lb bombs, it had a the forward fuse on it, which would be a zero delay fuse. The idea was for the bomb to go off above the ground, much cheaper than doing the same thing with a radar ranging fuse. We called them daisy cutters.

    On some drawings of a Stuka I notice some bombs that look similiar, in German it's labeled " dienartstab" . Translation please.
    Looks like we copied another German weapons idea.

    Very interesting, I'd seen them before but never really thought what they were for. Thanks Eric!

    Presumably this was to give an airburst effect against soft targets?

    Hi,
    My German is pretty good but Dienartstab doesn't ring a bell. The word stab in this means rod or pipe and looking at this threat would make sense. I guess the German word Dienartstab would suggest the type of fuse.

    Cheers,
    Sander

    That sounds similar to the little british invention called the proximity fuse, which was useful for both ground and aerial targets.

    Did some reading and asking around. The rod(fuze) is named after a German Stuka pilot Oscar Dinort and is indeed a proximity fuze. He had some part in the development of aerial bombs in the 1930's The German code for this type of ammunition was SD 50 through SD 500 Tel. for telescopic.

    The name Dinort or Dienart was I'm sure the same person.

    These types of fuzes....then being wooden rods, were used as early as WW1.

    Not as such, the proximity fuse, or VT as it was known in the US, was essentially a radar fuse that detonated when closer than a given distance to any object providing a radar return. The 'daisy-cutter' is an entirely mechanical device which would make abomb explode a distance above the ground equal to the length of the device. As I say, I presume this was done to create an airburst effect against troops and soft vehicles, significantly increasing the lethal radius of the weapon - otherwise much of the blast would have been absorbed by the ground.

    You're absolutley right!
    In a way this would be a mechanical near surface burst... as you say for soft skin vehicels and infantry in the open. In the article I read it was mentioned that the Luftwaffe experimented with almost 2 meter long rods. These bombs had to be carried horizontal due this rod and were not used in the, for example, He 111 as it had vertical storage racks.

    I have heard of a daisy cutter extension being up to 6 ft long, but the longest I ever saw was about 3 feet.
    The biggest advantage of them was a daisy cutter got some of the same effect as a Vt fuse at a fraction of the cost.

    back to the Ju 87 pic I posted this was an anti-personnel use and to balst off MT's and the trucks carrying the triple flak so dangerous to low flying LW ground attack crates. the bomb/rods were ugly effective used till wars end along with the single,e bomb carrier and the multi bomb-lets-butterflys

    I'm famaliar with the USA bombs from the Vietnam era and WW2, they had fuses in the front and rear. The German bombs appear to have no forward fuse. And for some aircraft they couldn't have a forward fuse because they hung nose up in the bomb racks, by a lug on the nose. Do they have a inertia fuse in the rear or center ? Hoe were they safetied?

    About the denomination, the word "art" is inside "Dien art stab", art means "type". "Dien" could be an abbreviation (no clue of what word). Another posibility is that Dienart be a last name of someone who designed the fuse.
    Edit: after post this I`ve just seen that another member has explained the meaning (I made it once again!).

    It is indeed a "dinort stabe" called after the infentor Oskar Dinort how was a pilot how also flow stukas.
    There where 3 oficial types, the din st 70 for 50 and 70 kg bombs and had a lenght of 600mm, the din st 250 for 250 kg bombs with a lenght of 410mm and the din st 500 for 500 kg bombs and lenght of 410mm.

    The rod extension, presumable the Daisy Cutter, was pretty common in a lot of air forces around WW2. It was an antipersonel, Anti-vehicle (including airplanes on the ground) weapon. Very useful if you were using them on Airfields and Soft Targets, it blew shrapnel all over the place. I think, but am not certain, that the 20th Air Force used them on the end of Para Frags. Nasty little bit of equipment if they did.

    I think the Daisy Cutter of Vietnam may suffer from confusing nomenclatures. There was one that was used to clear LZs in the jungle. But I think that was a FAE (fuel air explosives). Idea was you dropped on in the jungle and it detonated a few feet off the ground and blew a hole big enough to drop helicopters into. There was also a 2000lb Anti-Personel bomb with extensions called a Daisy Cutter. I guess it was a somewhat generic description.

    Lastly, the VT fuse was never called a Daisy Cutter that I've ever heard of, even though the results were somewhat similar. If it was, the name was probably slang.
