Background: The Drekavac Seafloor Active Sonar Array has been developed as part of the Greater Prussian Anti-Submarine Warfare Initiative, as part of the objective, set down by His Imperial Majesty, Alexander Kirillovich Blaken-Kazansky, to evolve a full range of anti-submarine warfare sensors and munitions for use by alliance members. Eiritin Maritime Shipyards, a lead submarine developer, had submitted bids in several of the tenders that resulted from the Initiative. One of the most important elements was the creation of the Drekavac Seafloor Active Sonar.
Technology: The Drekavac makes use of the transducer and reception components already used in a standard Greater Prussian directional command activated sonobuoy, indeed making use of the same sonobuoy body, enabling the use of shared production facilities and ease of handling in storage. However, unlike sonobuoys, the Drekavac was intended for a different use - a long-term seafloor mount.
In this context, the Drekavac no longer required a battery or a radio frequency communication system - instead, it would receive power and send back data over a seafloor cable network. The resulting space savings have been used better reinforce the housing tube, as now the Drekavac was expected to spend years on the seafloor rather than a mere 8 hours of operation time (of course, it was not expected to be outputting active sonar pulses the entire time - the pulses themselves are milliseconds long, and the continuous operation time is no more than 10 hours).
The Drekavac had been fitted with a mounting tripod intended to secure it to the seafloor as well as a stabilizer weight, ensuring a stable and optimal anchoring. Bolt anchors are also present for additional stability where possible.
Because the outputs of the Drekavac are fully digitized, the system can be integrated entirely into an existing or new national shore defense or anti-submarine defense network.
Tactics: The limited range and the requirement for seafloor mounting make it implausible to use Drekavac in the open ocean. A small number of these seafloor mounts can be used to secure entrance to a harbor or a body of water, and a larger number may be used to secure national waters against enemy invasion, if deployed in key locations on the continental shelf.
The Drekavac is best used in coordination with a full national array of antisubmarine warfare measures, e.g., magnetic anomaly detection aircraft, passive sonar, air-launched sonobuoys, and patrolling ASW ships. We recommend carrying out an environmental impact study before deploying any fixed sonar installations.
Operator’s Station at the operator’s station, the data from the Drekavac sensors is output in a format of both raw imagery that can be exported to a format of the operator’s choice, and as targeting data compatible with use in the Bastion II C3I system.
