sentences:  Just prior to release, the aircraft activates the Release Consent discrete and sends the weapon an arming command using the MIL-STD-1553 interface.The SMS will verify that the weapon release conditions have all been fulfilled, and it will activate the signals (not part of the MIL-STD-1760 interface) that cause the weapon to be released.In the case of a bomb, this is typically done by energizing an electro-explosive device that simultaneously opens the hooks that hold the bomb on the aircraft during carriage, and also operate a plunger that pushes the bomb away from the aircraft (at high speeds there is a tendency for the weapon to remain in close proximity to the aircraft after the bomb hooks open).
