  • Missile safe and arm system
    Patent number: 4620483
    Abstract: A missile safe and arm system incorporates an electrically triggered explosive train that extends from the missile body to an extendable probe and back to the missile body. When the probe is in its retracted position, the explosive train, and electrical triggering circuit is interrupted and detonator firing leads are shorted and the missile is in a safe condition. Upon launching and upon the extension of the extendable probe, the explosive train and its electrical triggering circuit become aligned, the detonator shorting lead is removed, and the missile is thus armed.
