What are the AGM 114 series safety features?

Back 57

Arming only after successful BIT, missile/launcher separation and fuze data received and safe separation signals received in correct sequence

Front 58

Describe the action of the warhead before impact in the AGM 114 series

Back 58

Arming sequence begins as missile is launched

28V passed to missile from aircraft immediately prior to launch. Controller CCA initiates a BIT of the ESAF device

After a successful BIT and when 15V of power is applied ESAF device checks for missile/launcher separation to occur

ESAF device monitors the longitudinal acceleration to determine if the safe arm distance has been reached

During missile/launcher separation and the attainment of the safe arm distance the ESAF device receives fuze data message from guidance section general purpose processor

This message is used to determine the detonation delay time between the precursor and main warheads

When the ESAF safe arm distance has been reached the arming process continues

ESAF device waits for a firing signal from impact sensor

When ESAF is armed the firing capacitors in the WFM and Main Module begin to charge

This sequence is complete before the motor is all burnt
