Rifled H.E. Projectile, 280mm



German Designation: Not Known

Employment: Not Known

Remarks: Slightly streamlined base.  Ballistic cap threaded to body of projectile.

Projectile has rifled design which takes the form of 12 longitudinal inclined splines (inclination 5 degrees, approximately).  These are approximately 60mm apart and are probably intended to engage in the rifling of the gun.

The splines do not appear to be machined from the main projectile body but are constructed separately on strips of steel which are then fitted into grooves cut in the projectile body.  These grooves are under-cut to produce secure attachment.  To the rear is a copper or bimetallic driving band, the probable function of which is to act as a gas seal.

H.E. Projectile with Disintegrating Rotating Bands (Sabot Type), 150mm



German Designation: Not Known

Employment: Not Known

Dimensions
Overall length (projectile): 25.6 inches
Diameter of bourrelet: 5.84 inches
Diameter of base: 6.01 inches
Total weight (projectile): 63.14 pounds
Weight of bursting charge: 7.48 pounds

No tracer


Fuze: Nose percussion fuzes AZ 23v

Markings: "R9" stencilled in body


 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.
