Tail assembly for a guided and fin-stabilized projectile

A tail assembly for a guided projectile, said tail assembly comprising:

• a fixed part (12) to be connected to a back of a main body of a projectile, and defining a longitudinal axis;
• and
• a movable part equipped with a plurality of stabilizing fins and mounted to a back of the fixed part being freely rotatable about said longitudinal axis;
• wherein said movable part is axially movable relative to said fixed part between:
• an abutment condition, wherein said fixed part and said movable part are in axial abutment with each other, and
• a spaced-apart condition, wherein said fixed part and said movable part are axially spaced apart, thus defining a perimetral gap in between;
• and
• wherein the tail assembly comprises an elastic group tending to retain said movable part in said spaced-apart condition.
