A projectile (10) reconfigures in flight from a launch configuration, in which the center of gravity is aft of the center of pressure, to a flight configuration, in which the center of gravity is forward of the center of pressure. The projectile includes a forward portion (12) and an aft portion (14), and the reconfiguration involves movement of at least part of one of the portions relative to the other portion. The projectile may have an overall substantially conical shape when in the launch configuration. The forward portion may include a substantially conical nose (20), and a cylindrical central body (22) attached to the nose. In the launch configuration, at least part of the central body may be located within a hollow (26) in a base (24) of the aft portion. The base may be slidable relative to the central body. |
