Abstract
The present invention relates to an artillery missile (1) intended for firing on a ballistic trajectory, with gliding characteristics which can be put into effect, after it has reached the summit of this trajectory, to increase the maximum range of the missile. In order to obtain these gliding characteristics, the missile is provided with extendable aerodynamic bearing surfaces divided into firstly canard fins (5-8), which are retracted in the front part of the missile body and can be extended after the summit of trajectory, secondly main bearing surfaces (9, 10) made of resilient material, which, likewise during launching, are curved in against and around the central part (3) of the missile body in shallow recesses adapted thereto in the outer casing of the missile and which, after the summit of trajectory and being extended, form the wings (9, 10) of the missile, and thirdly stem fins, which, durign at least launching, are covered i the retracted position by a protective cover (14) in the rear part (4) of the missile.
