H.E. Projectile, with disintegrating band, 105mm



German Designation: Not known

Employment: 10cm Flak 38
                       10cm Flak 37

Dimensions
Total weight (projectile): 23.1 pounds
Weight of bursting charge: 1.1 pounds

Type of Bursting Charge: TNT
No tracer


Fuze: Nose percussion fuze AZ 23v

Markings: Painted yellow

Packaging: One in a wooden crate.


 Remarks: At the shoulder of the projectile is a detachable guide band.  This band is trisected by cuts almost completely through the band and the complete band, which is a push fit on the shoulder, it is held in position by three ball bearings.  These are seated in cavities spaced equally round the periphery of the shoulder of the shell and project into cylindrical drillings through each segment of the guide band.  The drillings are threaded towards the outer circumference and the ball bearings after insertion are finally located by screws which seat the outer surface of the bearings.  After insertion of the balls and the positioning of the three screws, therefore, the guide band is firmly attached to the shell body, but should trisection of the guide band be completed, each segment, together with its retaining ball, would therefore be free to fall away from the shell body.

The rotating band holder is located at the base of the shell, which is keyed to receive it.  The holder itself is in three detached segments held in position only by the soft iron driving band.  Movement is prevented by three cylindrical pieces fitting into cavities located in the shell body and the driving band holder.  There are also three cylindrical pins between the segments.

It is believed that after leaving the gun the guide band and the rotating band holder are each split into three separate segments which, together with the ball bearings, pins and cylindrical pieces retaining them, are flung off.  The remaining projectile is then of much better aero-dynamic shape than is possible with a conventional projectile.

  1. Hi, we are making a film about WW2 equipment technologies and would love to be able to use some of the images from your pages on British Explosive Ordnance. Can you please let me know if you can provide hi res copies of the images (we can pay an access fee) or let me know the source of the images? We are on a timeline and need to get this done this week if possible. Thank you. Mattie mattie (at) apographproductions.com
