It was cylindrical, and the plan was to use curva linea to separate the mechanism end from the charge. Curva Linia is basically a shaped charge which would cut the end off of the mine which is the firing mechanism leaving the charge intact to be disposed of later.
I know there's loads of good science behind this, but that doesn't half sound optimistic!SpeckledJim said:

why did they bother painting bombs in ww2 sinse there was no chance of rust etc before use
If they were carbon steel (likely) they'd rust up overnight if outside. If it was a few weeks or months before you needed to drop them on someone they could be rusty enough to cause problems with the dropping mechanism.I think.
Weren't women the main part of the workforce assembling UK munitions? That's probably why Germany has so many UXBs.

Things like this are being constantly recovered from the mud being dredged from Portsmouth Harbour in preparation for the arrival of HMS QE. Depending on its location in the sludge, the city suffers from varying degrees of closure and evacuation until the thing is towed away and destroyed. They do seem to be very optimistic about the various bombs' ability to cause anything other than a headache for a few crabs.

Why do the fuses that get used in 13 amp plugs not show any visual signs when they blow? You can look at a blade fuse and see if it has blown, so why not plug fuses?
At a guess, something to do with containing the energy of the arc. An earth fault on a 230v appliance could give a fault current over 600 amps. A glass or plastic fuse body would just pop. You can buy glass-bodied fuses but they tend to have a much lower continuous rated current.Balmoral said:
the unexploded bomb itself still doesn't blow up, it just gets blown up.
That's not quite the case I don't think, the point of the bomb disposal team's "controlled explosion" as I understand it is to separate the detonator from the charge in order to incapacitate the bomb, not to destroy the bomb completely.48k said:

With some, bombs you can freeze the battery and remove the fuse to render it safe. All this of course is WWII stuff, obviously more technical these days I would think.
So to reiterate if you read my earlier post, the bomb/mine can explode during the disposal chappies trying to separate the mechanism from the charge.
Although they may have been buried since the war, all have the potential to explode.
Weren't a lot of german munitions found to be sabotaged by ze resistance during manufacture?
We often used to suck up UXBs when I worked on my little dredger, and although it had been subject to a bloody good hiding having rattled up a big steel tube, through an impeller and down a grading chute, I never once thought to myself, I think I'll go and pick that shell up & lob it overboard.....even crabs & angry flatfish made me think twice...

POW's were used in German factories, one thing they did to help us was to make some connecting rods were too short, so when the bomb was dropped and something turned to arm it, it didn't.We often used to suck up UXBs when I worked on my little dredger, and although it had been subject to a bloody good hiding having rattled up a big steel tube, through an impeller and down a grading chute, I never once thought to myself, I think I'll go and pick that shell up & lob it overboard.....even crabs & angry flatfish made me think twice...
Good idea, but when the bomb disposal squad were disarming them, they had no idea some weren't armed in the first place.
You mentioned a dredger. Pal of mine was called out to a shell lodged in a dredger, he determined it to be a dummy so started to burn it out. Only it was a live shell. At least it was quick.
Anyway what's the brass thing I posted, someone must know.

Reading that about your mate made me physically flinch. Condolences. Good idea, but when the bomb disposal squad were disarming them, they had no idea some weren't armed in the first place.

Bomb disposal guys = nails.
