Steerable projectile
First Claim
1. A steerable projectile comprising a body portion and a nose portion, the nose portion and the body portion being substantially coaxially arranged along a co-axis and rotatable relative to one another about said co-axis, the nose portion further comprising an asymmetric formation operable to enable said projectile to be subjected to off-axis drag during flight, wherein said asymmetric formation comprises one or more active surfaces, each active surface extending in a direction that is substantially radial with respect to said co-axis, the active surfaces not extending beyond the radial extent of said body portion, and each active surface being defined so as to cause the imparting of a drag component on said projectile wherein the drag component is perpendicular to the trajectory of said projectile.

Abstract
A steerable projectile (30) comprises a body portion (32) and a nose portion (34). The nose portion and body portion are substantially coaxially arranged and rotatable relative to one another about their co-axis. The nose portion further comprises an asymmetric formation (36) operable to enable the projectile to be subjected to off-axis drag during flight.
