Hi,
These are the remains of a Japanese Navy 250kg incendiary bomb, Type 2, No.25, Mark 3, Model 1, which was recovered by EOD personnel. The nose fuze has been identified as a Japanese A-3(a) navy mechanical impact nose fuze. This type of bomb is usually dropped from 20,000 feet and explodes between 150 - 200 feet above the ground. However, this bomb exploded on impact with the ground after the Navy D-2(a) clockwork delay aerial burst, tail fuze, failed to operate correctly. The bomb travelled a metre into the earth with the majority of the incendiaries burning in the ground. The surrounding area was littered with burnt and unburnt incendiaries. All the rusty looking pieces were recovered from the hole. No tail fin was found. All unburnt incendiaries were destroyed by EOD. I have found a website explaining the occurrence of one of these bombs failing to explode in New Guinea in 1943. I have added the web link for those who may be interested in having a look. Also attached are pictures of the Japanese bomb and the different types of Japanese A-3 nose and D-2 tail fuzes from the OPNAV 30 3M Handbook of Japanese Explosive Ordnance.
Cheers,
