Abstract

There is provided an ammunition unit, preferably for training purposes, intended to be fired from a gun barrel at supersonic speed. The ammunition unit comprises an intermediate body part (1) to which is connected a substantially cylindrical spike (2) as well as a finned tail section (3). The length (L1) and design of the spike and the design and connection of the tail section to the intermediate part are such that the ammunition unit, up to a predetermined firing distance, has substantially the same ballistic properties as the equivalent normal live ammunition but which has a significantly reduced maximal firing range as compared with such normal live ammunition. This is because a dead air stream zone is obtained around the spike at supersonic speeds, but at sub-sonic speeds the air stream follows the spike surface and results in a substantial braking force. The length L1 of the spike is 1.6-2.0 the diameter D of the body a truncated conical part 1a of the body has a length of 1-3% of the total length of the unit and a conical angle between 10 DEG and 20 DEG .
