Rifled H.E. Projectile, 280mm

German Designation: Not Known

Employment: Not Known

Dimensions

Overall length (projectile): 49.4 inches (approx.)
Distance from base to band: 5.079 inches
Width of bimetallic rotating band: 0.787 inches
Length of splines: 18.897 inches
Weight of bursting charge: 66 pounds

Total weight (projectile): 551 pounds

Small tracer present

Fuze: Nose - Hbgr. Z. 35k; Base - Bd. Z. 35K

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.

Next Time: 50mm to 80mm Mortar Rounds
