Abstract
A technique for launching a missile that avoids some of the costs and disadvantages for doing so in the prior art. In particular, the illustrative embodiment of the present invention uses an electromagnetic catapult to throw the missile clear of the launch platform—with sufficient velocity to attain aerodynamic flight—before the missile's engine is ignited.

1-38. (canceled)
An apparatus comprising:
- a sled;
- a first coil that is concentric around an axis and that is substantially immovable with respect to the sled;
- and
- a second coil that is concentric around the axis and whose inner diameter is greater than the outer diameter of the first coil, wherein the second coil and the first coil are not electrically connected;
- wherein the flow of a first electric current in the first coil and the flow of a second electric current in the second coil mutually induce the sled to move along the axis.

An apparatus comprising:
- a sled having a rest position on an axis;
- a first coil that is concentric around the axis and that is substantially immovable with respect to the sled;
- a second coil that is concentric around the axis and whose inner diameter is greater than the outer diameter of the first coil, wherein the second coil and the first coil are not electrically connected;
- and
- a tube having a first end and a second end, wherein the tube is concentric around the axis, and wherein the inner diameter of the tube is greater than the outer diameter of the first coil;
- wherein the rest position is at the first end of the tube, and wherein the tube contains the sled when the sled is at the rest position;
- and
- wherein the flow of a first electric current in the first coil and the flow of a second electric current in the second coil mutually induce the sled to move from the rest position toward the second end of the tube.
