Atlas Elektronik has released details of successful sea trials of SeaSpider anti-torpedo-torpedo (ATT) for torpedo defence studies in the Baltic Sea.

The trials were conducted in cooperation with the German Bundeswehr Technical Center for ships and naval weapons, maritime technology and research (WTD 71) on a WTD 71 multipurpose vessel.

During the trials, the company tested the full ‘sensor to shooter’ functional chain of a hardkill surface ship torpedo defence system with torpedo detection, classification and localisation (TDCL) sonar and the third-generation SeaSpider prototype with its above water launcher.

SeaSpider targeted both an Mk37 torpedo-derived AUV and DM2A3 torpedoes at the WTD71 test range.

“Atlas Elektronik appreciates the cooperation with the German Bundeswehr Technical Center for ships and naval weapons.”

These threats were detected and localised with passive and active TDCL. Atlas used the attendant data to cue the SeaSpider launch.

According to Atlas, SeaSpider acquired the torpedoes and homed in into the closest point of approach (CPA).

A successful ‘intercept’ was verified using acoustic and optical means. The information about the trials has been released after a full evaluation of the trial results last year.

In a statement, Atlas said: “Atlas Elektronik appreciates the cooperation with the German Bundeswehr Technical Center for ships and naval weapons, maritime technology and research (WTD 71) in the ongoing torpedo defence studies.”

The company noted that it is undertaking serial product development of the SeaSpider ATT and the Atlas Elektronik surface ship torpedo defence suite.

SeaSpider is designed to protect ships, submarines and sailors against torpedo attack and is capable of operating in both deep and shallow water.

It is part of Atlas Elektronik’s wider solution to provide torpedo defence to the full functional chain ‘from sensor to shooter’.
