Abstract

A projectile has a main body having a smooth end region, an intermediate sleeve over the smooth end region, a guide mechanism sleeve and guide fins. In one embodiment, the intermediate sleeve has an internal surface and an external thread, the intermediate sleeve being soldered at the internal surface to the smooth end region of the main body. The guide mechanism sleeve has an internal thread screwed with the internal thread onto the external thread of the intermediate sleeve at a tail region of the projectile. The guide fins are fixed to the guide mechanism sleeve. In a second embodiment, the projectile includes a longitudinally extending main body having an end region conically tapered toward a front end of the projectile, and a conically tapered intermediate sleeve having longitudinally extending slots, regions of the intermediate sleeve between the slots being radially elastic. The intermediate sleeve is fitted over the tapered end region of the main body so as to clamp the tapered end region. The guide mechanism sleeve which fixes the guide fins at a tail region of the projectile, has a conically tapered inner wall region lying frictionally locked against an outer surface of t…
