In an ammunition unit in the form of a shell (1), projectile or the like which is fin-stabilized, an extendable fin is utilized which is intended to be retracted during firing in a barrel or the like and to be extended as soon as the shell or the like has left the barrel. The extendable fin is intended to increase the stability of the ammunition unit in the ballistic trajectory. The extendable fin consists of two fin parts (4′and 4″) supported separately in relation to each other and which in their extended positions are joined together and form the fin.


In a fin stabilized ammunition unit including a projectile for firing into a trajectory, an improved stabilizing apparatus comprising: a projectile housing having a fin carrying longitudinal groove; first and second longitudinally extending planar fin parts, disposed within said groove, which have abutting ends, each mounted for rotation in a common plane containing a longitudinal axis of the projectile on separate pivot points adjacent said abutting ends in said groove, remaining free ends of said fin parts extending in opposite directions from said piv...
