  • USPC 244/3.1 Missile stabilization or trajectory control: Parent class USPC 244. Subject matter including means which operates inherently to compensate for undesired changes in attitude or which operates to affect the trajectory or course of an unmanned aerial missile. The term "missile" used here includes: (a): (1) a device explosively propelled through and from the barrel of a gun or (2) a device carrying an explosive which when actuated either (a) detonates to destroy or damage the carrying device, or (b) burns or combusts within the carrying device to (1) release the products of combustion to the atmosphere, or (2) generate a gas to eject an object or substance from the carrying device, or (3) generate heat within the carrying device which damage or partly damages the carrying device; (b) a device having a payload and an attached reaction motor for propelling payload through the earth’s atmosphere. (Reaction motors eject a motive fluid.) This definition excludes aircraft which are sustained by air. For such subject matter see USPC 244/4+. Missiles for manned flight don't go here but in USPC 244/75.1 to USPC 244/99.9. This definition excludes explosive devices designed to be dropped from the air or watercraft on an objective below, known as "drop bombs"; these are classified in USPC 102/382+. This definition excludes missiles having a payload for display or amusement (e.g., fireworks or toy novelties) with a reaction motor driven by the products of combustion. Pyrotechnic rockets are classified in USPC 102/347+. This definition excludes pyrotechnic devices (firework creating flash, noise or smoke) having vanes, wings, parachutes, balloons, or propellers; for these, see USPC 102/335+ and USPC 102/367+. This definition excludes a rocket having a toy, amusement or display (nonpyrotechnic) payload with a reaction motor driven by other than products of combustion; these are classified in USPC 446/56.
