Abstract: The present invention enables the passive initiation of a deployment sequence for a countermeasure payload. The invention comprises an initiator coil that is positioned inside an electromagnetic countermeasure launcher. When the electromagnetic countermeasure launcher electromagnetically generates propulsive force to propel a payload to its deployment position, inductive coupling between one or more propulsion coils of the launcher and the initiator coil induces current to flow in the initiator coil, which thereby initiates the deployment sequence.

Abstract: A restraint for immobilizing a projectile with respect to its launch system is disclosed. When electromagnetic force is applied to the restraint, the restraint releases the projectile, thereby enabling its launch.

Abstract: A system for launching a countermeasure device is disclosed. In the illustrative embodiment, the system uses an electromagnetic catapult to throw a countermeasure payload, wherein the azimuth, elevation, and propulsive force of the electromagnetic catapult are controllable.

Abstract: A system for launching a plurality of projectiles from a single launch tube is disclosed. In the illustrative embodiment, the system uses an electromagnetic catapult to sequentially throw a first projectile and a second projectile. The first projectile is thrown while the second projectile is temporarily restrained within the launch tube.

Abstract: An electromagnetic missile launcher is disclosed that provides greater flexibility for use with a variety of missile types and also provides potentially higher performance and efficiency as compared to prior-art electromagnetic missile launchers.

Abstract: A multiple missile launcher has a plurality of canister holding chambers. Each canister includes a standard connector for connection by a standard cable to a missile launch sequencer. Each canister is loaded with four missiles. The cable has more than enough signal paths to couple launch and safe signals to a single missile, but not sufficient to independently control four missiles. A missile selection signal generator generates selection signals which are sent over a selected one of four separate signal paths of the cable to directly (without intervening active elements) actuate a relay associated with the selected one of the missiles. The four relays are part of a multiplexer which couples the signal set for launch and safe to the selected one of the missiles.
