Background: As part of the Greater Prussian Anti-Submarine Warfare Roadmap, the necessity arose to create a series of sonar decoys, capable of deceiving enemy active and passive sonars, as well as being used in peacetime exercises for submarine and ASW warfare training. As part of the solution, the Greater Prussian Crown has announced the tender for Doppleganger-533 - an active/passive sonar decoy, capable of being launched from a standard 533 or 660 millimeter torpedo tube.
After multiple designs were considered, Allanean Arms, Eiritin Maritime Shipyards, Rythar Industries, and the Serene Power Company all advanced to the initial stage of tender. However, only the Rythar Industries and Allanean Arms designs moved on to the direct testing stage, as Eiritin Maritime Shipyards failed to provide assurances that it possessed the facilities to produce the decoys in the necessary quantities, and the Serene Power Company design failing to meet some of the initial tender characteristics.
After maritime testing was completed under the aegis of the Greater Prussian Navy, the resulting weapon system was accepted for early service both for the Greater Prussian Navy and the Free Kingdom Navy, and initial production runs of 1,000 decoys were ordered for each entity as the Doppleganger-533
The decoy may be used either in training submarine and ASW vessel crews, or as part of submarine or antisubmarine warfare, to deceive enemy sonars and other forms of reconnaissance.
Technology:The Doppleganger-533 has the form factor common to 533-millimeter torpedoes, and can be launched from standard 533 millimeter launchers. As its principal mode of operation, it has an active acoustic field generator that is intended to imitate the acoustic signature of a submarine (thus, intended to deceive passive sonars and hydrophones that may be listening for such signs). The acoustic field generator is to be programmed upon launch to imitate the acoustic signature of a given submarine model (most common models may be plausibly imitated).
In addition, if the Doppleganger-533 receives a ‘ping’ from a common model of active sonar, it will broadcast back a ‘ping’ imitating the sounds it had just received, with the attempt to imitate a full-sized sonar target.
Finally, at the operator’s preference, the Doppleganger-533 can be programmed to rise close to the surface and unfold an imitation antenna/periscope, broadcasting radio signals intended to imitate those of a submarine as well as to be detected by aircraft radar.
Tactics: The Doppleganger-533 may be used defensively (to decoy the attacks of enemy submarines) or offensively (to decoy enemy ASW patrols with long-range launches).
Moreover, it is also plausible to use the Doppleganger-533 in reconnaissance missions, where it is to be launched at an extended range to provoke a response from enemy submarines or anti-submarine patrols or to distract from the operations of one’s actual submarines or other vessels.
