well it's part of an artillery projectile, you would have to post accurate measurements of the length and diameter, as well as some shots of both ends to really id it. It looks to not have a fuse on the tip so it should be safe to move around.
yep looks like a WW2 era artiilary shell warhead seems there is no nose (fuse) upon it * so it should be unarmed and thus safe to move however please note ***** the WW2 era japanese had a bad habit of booby trapping stuff - so I'd think twice about moving and if I still wanted to move it I'd look at it very very very carefully before even thinking of touching it
I don't think it is an artillery projectile, because those don't have a threaded iron body. (I do see threading on it, not simple ridges/rings.) It could be the explosive head of a rocket or bazooka-round. Or it might not be a military item.
Precise measurements are needed.
Also, we need to see more photos -- particularly, close-up views of its base, and the front, to see if it has a fuzehole, which would be threaded.

I was wondering about those threads as well, rocket makes sense, I couldn't find any mortar rounds to match, I'll look a bit more when I get a chance.
Very good research, Mike! The photo shows the large iron threading visible through the cracked outer casing of the rocket's fuel-section, below the explosive head. Unscrew the fuze in the nose, and that 2.75" rocket warhead would be a very close match to the Guam mystery-object. Not quite an exact match, but very close. The slight difference could be due to the Guam specimen presumably being from 1944, and the Cuddleback Lake Air Force Range specimen being from some decades later.
Perhaps the Guam finder can supply exact measurements and other photos which will confirm (or cancel) the ID.
it might be the warhead (minus the fuse part which it used the same fuse as a mortor round ) to a japanese WW2 era type 4 * 70 mm (2.7559 inches) japanese anti tank rocket gun (similar somewhat to a us bazooka )
or a 60 mm (2.36 inches) american bozooka type warhead minus the fuse
If it turns out to be a Bazooka round, and once some measurements are established, the following Wikipedia link has some interesting information and various specs that could prove helpful.
Together for comparison. I missed seeing ffuries "threads" the first time around ... and its lookin' good in the neighborhood. But exactly "What Is It?" ... again.
As I said way back in post #4 in this discussion, the Guam object is either a rocket's explosive head, or a bazooka's, because artillery projectiles don't have a threaded body. I've now done some research, which indicates it is indeed a rocket's warhead. Check the diagrams of rocket warheads at the following website, which show they have threading at the top of the rebated section on the warhead's rear, just like the Guam object. The warhead's rear area is rebated and threaded so it can be screwed into the rocket's tubular main body, which contains the fuel and rocket-motor.
