The SAM-ALWT is an Electro Mechanical Safety and Arming Mechanism designed for underwater torpedo applications. It incorporates multiple safety interlocks to ensure the warhead remains inert during handling, storage, transportation, and launch. SAM-ALWT is a single-shot device that detonates the warhead upon receiving a trigger signal from the Autonomous Onboard Controller (AOBC). It operates in conjunction with the Electronic Control Unit (ECU) to arm and initiate the ADM explosive train. The system features dual-redundant acceleration sensing and is engineered for reliable operation in harsh underwater environments.

The SAM-ALWT is an Electro Mechanical Safety and Arming Mechanism designed for underwater torpedo applications. It incorporates multiple safety interlocks to ensure the warhead remains inert during handling, storage, transportation, and launch. SAM-ALWT is a single-shot device that detonates the warhead upon receiving a trigger signal from the Autonomous Onboard Controller (AOBC). It operates in conjunction with the Electronic Control Unit (ECU) to arm and initiate the ADM explosive train. The system features dual-redundant acceleration sensing and is engineered for reliable operation in harsh underwater environments.
- Safe Condition:SAM remains unarmed, ensuring complete safety during handling, transport, and storage.
- ECU-Based Arming:The SAM arms upon receiving the designated firing pulses from the Electronic Control Unit (ECU).
- Dual-Redundant Sensing:Arming is supported by both electrical and mechanical acceleration sensing, enhancing system reliability.
- Isolated Inputs:Eight digital isolated inputs provide operational flexibility and secure signal interfacing.
- Rotor Mechanism:The Arming and Detonation Mechanism (ADM) includes a rotor-based safety interlock for arming and unarming control.
Fuze Safety:
The SAM-ALWT ensures that the firing train remains inactive until all arming conditions are met. Even in the event of a premature trigger or inadvertent primer ignition, the system does not transmit a firing pulse, thus maintaining warhead safety under all non-launch conditions.
Distant Arming:
Arming occurs only after launch confirmation, detected through acceleration and mechanical forces. This prevents any possibility of premature warhead activation while still in the torpedo tube or during logistics handling.
FUZE ACTION:
The SAM-ALWT functions by sensing acceleration and electrical signals. It activates the ADM explosive train when the correct conditions are fulfilled, ensuring controlled and reliable warhead detonation. The mechanism is designed for precise underwater performance.
