Method and arrangement for extending the range of fire of a fin-stabilized artillery missile. The fin-stabilized artillery missile (1), which is fired in a ballistic trajectory, has fins (3-6), which have been given a sawtooth-shaped leading wing edge (7) that has been found to give the missile (1) an extended range of fire and improved manoeuvrability.

1. A method of firing a fin-stabilized artillery missile from a gun, comprising:providing a fin-stabilized artillery missile comprising a shell body and a plurality of fins arranged around a periphery of the shell body, wherein the fins have sawtooth-shaped leading edges; and firing the shell, where
1. A method of firing a fin-stabilized artillery missile from a gun, comprising:providing a fin-stabilized artillery missile comprising a shell body and a plurality of fins arranged around a periphery of the shell body, wherein the fins have sawtooth-shaped leading edges; and firing the shell, wherein the fins deploy from their positions around the periphery of the shell body upon firing, wherein each fin has at least two teeth along its sawtooth-shape leading edge, and wherein the fins comprise a plurality of triangularly-shaped subsidiary areas which extend forward in a direction of flight of the missile, the subsidiary areas being separated by triangular recesses. 2. The method of claim 1, comprising:correcting a course of the missile using the fins. 3. The method of claim 1, further comprising concealing the plurality of fins before firing the fin-stabilized artillery missile from the gun, and uncovering the plurality of fins after firing the fin-stabilized artillery missile from the gun.4. The method of claim 3, wherein the fins comprise a resilient material and, before firing the fin-stabilized artillery missile from the gun, the fins are rolled around the shell body.5. The method of claim 2, wherein the shell body includes a band tack arranged around a circumference of the shell body.6. The method of claim 2, wherein the subsidiary areas extend forward between about one sixth to one third of a width of a fin.7. The method of claim 4, wherein the subsidiary areas extend between forward about one sixth to one third of a width of a fin.8. A fin-stabilized artillery missile, comprising:a shell body; and a plurality of fins arranged around a periphery of the shell body, wherein the fins have sawtooth-shaped leading edges, and wherein the fins are deployable from their positions around the periphery of the shell body upon firing of the missile wherein each fin has at least two teeth along its sawtooth-shaped leading edge, wherein the fins comprise a plurality of triangularly-shaped subsidiary areas which extend forward in a direction of flight of the missile, the subsidiary areas being separated by triangular recesses. 9. The missile of claim 8, wherein the fins comprise a resilient material and are rolled around the shell body.10. The missile of claim 8, wherein the shell body includes a band track arranged around a circumference of the shell body.11. The missile of claim 8, wherein the leading edges are knife edges.12. The missile of claim 8, wherein the subsidiary areas extend forward between about one sixth to one third of a width of a fin.13. The missile of claim 9, wherein:the shell body has a band track arranged around a periphery of the shell body; the leading edges are knife edges; and the subsidiary areas extend forward between about one sixth to one third of a width of a fin. 14. A fin-stabilized artillery missile, comprising:a shell body having a band track arranged around a periphery of the shell body; a plurality of fins arranged around a different periphery of the shell body, wherein the fins have sawtooth-shaped leading edges; and the fins being rolled around the shell body when the missile is in an unfired condition, wherein each fin has at least two teeth along its sawtooth-shaped leading edge comprising a plurality of triangularly-shaped subsidiary areas which extend forward in a direction of flight of the missile, the subsidiary areas being separated by triangular recesses, and wherein the fins are deployable from their positions around the periphery of the shell body upon firing of the missile.
