Leitwerkes are resin-treated, pressed paper, aerodynamic tails utilized with the BM 1000 mines except when the SH 8 and 9 are used in which case the LS 3 parachute is depended on to maintain ballistic stability. They consist of a truncated cone fitted with four radial fins enclosed in a shroud ring secured to the domes of the mines by rivets. These tails break off upon impact.
