(under subclass 3.1) Apparatus wherein the missile is rotated about its longitudinal axis during the flight of said missile for maintaining stability by means on the missile which reacts with the atmosphere (e.g., fin, etc.) or a fluid reaction jet issuing from said missile.
(1) Note. This definition excludes a "missile" where the sole means to rotate it is the coaction between pregrooved rifling band and a rifled barrel and the engraved grooves on the band are disclosed for the purpose of reacting with the atmosphere to aid in the rotation of the missile, such a missile is classified in Class 102, Ammunition and Explosive Devices, along with conventional rifling bands which may inherently perform the same function.
