Description
The torpedo uses a CIACIO-S seeker, consisting of an acoustic homing head containing the transducer assembly, transmitter, and related Beamforming circuits, and a frame housing all the remaining electronic components. The homing head is capable of active, passive, or mixed modes for closing onto its target. It can also discriminate between decoys and real targets in the presence of heavy reverberations especially emitted pulses and signal processing.
The latest version is the A244-S mod.3 torpedo.
The A244/s are developed and manufactured by the Italian WASS (Whitehead Alenia Sistemi Subacquei) firm.
