An engineer from St. Petersburg has developed and patented a submarine equipped with an external unmanned combat module. The sealed complex operates autonomously, creating decoys and enhancing the submarine's combat characteristics.

According to the utility model description, the module is attached to the submarine's hull and can be detached when necessary.

The design provides for the use of a frame or combined hull. Before deployment, the module is in a compact state, and before operation, it takes on the necessary shape by filling with high-pressure gas. This solution allows for reduced dimensions during transportation and simplifies placement on the submarine.

The developer proposes using the module in several scenarios. It can simulate acoustic and external signs of a submarine, distracting enemy forces, act as a decoy, perform reconnaissance functions, and carry various means of destruction. With appropriate equipment, the module can be used as an autonomous weapon or as a covertly installed naval mine.

The patent also describes the possibility of equipping the system with means for detecting underwater, surface, ground, and air objects. It is assumed that the equipment will be able to operate according to pre-set algorithms or using artificial intelligence technologies. Hydroacoustic communication, cable connection, or radio channel are provided for module control.

The patent author believes that the proposed design will significantly expand the arsenal of technical solutions for modern submarines, while maintaining a relatively low cost of manufacturing detachable modules due to the absence of a complex pressure hull and life support systems.
