The British
Surface Ship Torpedo Defence (SSTD) system entered into service with the British Royal Navy
in 2004. The system is produced by Ultra Electronics
and is known as S2170 by the Royal Navy
and as Sea Sentor in the export market.
The system consists of
The system is a foot-print compatible replacement for the AN/SLQ-25 Nixie
system previously installed on British warships.
The passive acoustic towed array is specifically designed to detect torpedoes (unlike traditional ASW sonars) and has additional in-built non-acoustic as well as acoustic intercept sensors. Through advanced AI processing it is able to generically identify torpedoes as well as classify specific weapon types and modes and undertake threat evaluation and posturing analysis. The system provides tactical advice dependent upon the specific threat weapon, mode and posture to maximise vessel survivability, which typically involves vessel manoeuvres and also includes the deployment of countermeasures. The countermeasures - both towed and expendable variants - lure the threat away from the vessel in a soft-kill manner.
Ultra Electronics also produces a hard-kill variant known as the TRAPR DCL
system currently under development for the US Navy.

DCL Technology Demonstrator programme
The US DCL demonstrator program is aimed at proving that an active torpedo detection system is able to resolve a salvo of torpedoes with sufficient time and accuracy that an anti-torpedo torpedo may be fired back to hit and destroy the threat.The DCL systems consist of an active source emitter...
