WWII 11.5lb British practice bomb

I was visiting a much younger collector on my last Canadian stop. He has a piece he’d like to identify. So here is RimPin and his practice bomb.


11 1/2 lb practice bomb, standard British pattern for 1940s up to early '70s.
Should be fitted with a brass striker in the nose that would have initiated the No.28 Detonator Burster, fitted in the middle section.The heavy nose section should be able to be unscrewed from the tail.
In use the tail was filled with Titainium Tetrachloride as a smoke producing agent.





U.S.N.B.D. stands for United States Navy Bomb Disposal (school). Does it still exist?

NAVY EOD now I believe.


Excellent information guys!!! Thank you all for these details! I truly appreciate the effort!


Hi All,
I have the same 11.5lb practice bomb. It was brought home by my father after he got out of the RCAF post second world war. It’s banged up (used as a gate closing weight for many years). I would love to get it restored. Dad always told us it was deactivated but obviously I have no way of proving this. Anyone have any ideas on either of these issues?

I show three Practice bombs 11 1/2 lb. WW2 white painted usually by McH&K or two P’s back to front? and a later blue painted one by Stokes. The tail changed in the 1990’s? as shown and was called a 5kg Practice Bomb. These are all Australian made it seems.
Was the yellow painted bomb just some repaint? Ron.
