The A244-s is an Italian lightweight, fire-and-forget torpedo employed for anti-submarine warfare. It can be launched from surface vessels or aircraft and locates the target using an acoustic seeker.

This section needs expansion. You can help by adding to it. (January 2015)

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, manufactured by Leonardo.^[1]
