Abstract

The present invention relates to a fin-stabilized missile (1) of the type which is intended to be fired at high acceleration towards a defined target along its trajectory and which can be guided in the trajectory and which, for stabilizing it in the trajectory, is provided with stabilizing fins (3, 32) arranged at its rear end, and control elements (6, 7) which are arranged at its front end and are intended to guide the latter, and whose rear part, in which the fins are secured, consists of a body part (4, 31) which can rotate freely relative to the main part (1, 29) of the missile about a bearing (14, 36) arranged concentric to the longitudinal axis (L) of the missile (1). According to the invention, said bearing (14, 36) is arranged near the dividing plane between the missile (1) and the body part (4, 31) and has a short length in the longitudinal direction of the missile, this having been made possible by the fact that it has been given a large diameter compared with its length and it has been designed with special load-bearing contact surfaces (20, 21, 27, 28) which limit the stresses during ramming and firing and during the flight of the missile (1) through the air. The freely rotatable body part (4, 31) for the fins (32) can then in turn be axially displaced from a launch position located inside the missile to a flight position where the fins (32) are pushed out behind the rear plane of the missile, where they can rotate freely.
