A missile to be fired from a barrel contains a tail, a tail sleeve attached to the tail, a stop element fixed to the tail sleeve, and a movable structural part disposed at the tail. Fin assembly wings are provided and are to be released from a subcaliber launch position to an overcaliber functional position by the movable structural part moving toward the stop element through a given distance. A pressure area is disposed between the tail end surface and the movable structural part. A propellant gas enters the pressure area during the firing of the missile, for moving the movable structural part away from the tail end surface against the stop element after firing. Bearing shafts are supported by the tail sleeve, the fin assembly wings are configured as a wrap around tail fin assembly held about the bearing shafts.

What is claimed is: 1. A missile to be fired from a barrel, comprising: a tail having a tail end surface; a tail sleeve attached to said tail; a stop element fixed to said tail sleeve; a movable structural part disposed at said tail; fin assembly wings to be released from a subcaliber launch posit
What is claimed is: 1. A missile to be fired from a barrel, comprising: a tail having a tail end surface; a tail sleeve attached to said tail; a stop element fixed to said tail sleeve; a movable structural part disposed at said tail; fin assembly wings to be released from a subcaliber launch position to an overcaliber functional position by said movable structural part moving toward said stop element through a given distance, said fin assembly wings having cutouts formed therein; a pressure area disposed between said tail end surface and said movable structural part, a propellant gas entering said pressure area during firing of the missile, for moving said movable structural part away from said tail end surface and against said stop element after firing; bearing shafts supported by said tail sleeve, said fin assembly wings configured as a wrap around tail fin assembly held about said bearing shafts; and said movable structural part being a locking pot having a base with a propellant gas inlet formed therein, said pressure area disposed in front of said base through which said propellant gas inlet passes, said movable structural part further having a pot casing with holding pins extending into said cutouts in said fin assembly wings. 2. The missile according to claim 1, wherein said tail sleeve has elongated holes formed therein through which said holding pins extend. 3. The missile according to claim 1, wherein said tail sleeve has axially oriented longitudinal cutouts formed therein, and in each of said cutouts of sail tail sleeve one of said bearing shafts is provided for an associated one of said fin assembly wings. 4. The missile according to claim 1, wherein: said tail has a cylindrical surface; and said pot casing is disposed between said tail sleeve and said cylindrical surface of said tail. 5. The missile according to claim 1, wherein said holding pins each have a pin which projects radially away from said pot casing and, at a distal end of said pin, said holding pins each have a holding member, which is oriented axially forwards, for engaging said fin assembly wings. 6. The missile according to claim 5, wherein each of said cutouts (32) of said fin assembly wings has a longitudinal extent which is slightly greater than an axial longitudinal extent of a holding member which is provided on a respective one of said holding pins. 7. The missile according to claim 5, wherein each of said fin assembly wings has an attachment disposed on a distal, axially oriented longitudinal edge of said fin assembly wings, with an axial size of said attachment being slightly smaller than said axial longitudinal extent of said holding member of an associated one of said holding pins. 8. The missile according to claim 1, wherein said pot casing has shearing sections; and further comprising shear pins each having a weak point and each projecting radially inwards from a respective one of said fin assembly wings and can be sheared off by a respective one of said shearing sections on said pot casing. 9. The missile according to claim 8, wherein said pot casing has projections projecting radially and form said shearing sections. 10. The missile according to claim 1, wherein said stop element which defines a release position for said locking pot is provided at said tail behind said locking pot and is at an axially defined distance from a rear tail end surface of the missile. 11. The missile according to claim 10, wherein said stop element is formed by a ring attached to a rear end of said tail sleeve, said ring having an internal diameter being less than an external diameter of said tail sleeve. 12. The missile according to claim 11, wherein said tail sleeve has elongated holes formed therein through which said holding pins extend. 13. The missile according to claim 11, wherein said tail sleeve has axially oriented longitudinal cutouts formed therein, in each of said cutouts of said tail sleeve one of said bearing elements is disposed for an associated one of said fin assembly wings. 14. The missile according to claim 11, wherein said pot casing of said locking pot is disposed between an inner surface of said tail sleeve and a cylindrical surface of said tail.
