Protecting war ships from torpedo attack is considered as the most challenging task in Anti-Submarine Warfare. Torpedo Defence System (TDS) is an essential fitment on modern high value platforms. Timely detection and identification of a torpedo attack is the primary function of a TDS. Localisation and countermeasures against the weapon are the next stage in torpedo defence. Detection of modern torpedoes with long endurance can only be achieved using an underwater sensor suit with wide frequency coverage. Tactical use of multiple counter measures is essential for evading an attacking torpedo with intelligent homing mechanism. Individual sensors and counter measures are no longer considered as a solution; they are rather considered as components of a large network of systems to protect the platform from torpedo attack. A System of Systems (SOS) architecture with multiple sensors, processing techniques, countermeasures and tactics are presented in this paper for achieving fail-safe torpedo defence capability.

“…The typical approach is to go by the functional design wherein focus is placed on the operational and functional requirements as desired by the user and methods are devised to achieve the functions from the inputs fed into the system. Ways of presenting the system outputs to meet stated objectives and performance parameters are also designed keeping in mind the physical configuration, space availability and other form and fit requirements 4 .…”

Requirement study and analysis forms a key component in conceptual design of new products and systems. For complex systems like defence equipment, concept design is very important and should primarily satisfy all user requirements. The paper brings out a new generative model for concept design of defence systems using principles of systems engineering. A structured model and methodology is presented starting from capturing the user requirements, developing multiple solutions, short listing the candidate solutions and finally selecting one or two feasible designs. The model and process is illustrated with the help of a case study on the development of a torpedo defence system for naval ships.

Simulation Testing of Maritime Cyber‐Physical Systems: Application of Model‐View‐ViewModel

From the perspective of the system of systems development, system-level functional testing is required for designing subsystems. This study utilizes modeling and simulation techniques to analyze the operational behaviors of the subsystems and confirm data communication between them. The targeted system in the study is a naval combat system (NCS), which is a typical type of defense cyber-physical system (CPS). Three types of models were designed for the simulation testing of the NCS: a combat-management model for simulating the overall computational activities, physical models to confirm the intrasubsystem behaviors, and data integration models to test the intersubsystem communications. These models are realized with the Model-View-ViewModel design pattern, which strongly facilitates graphical user interfaces being decoupled from model logic and data. We consider underwater combat scenarios as an application. Six significant physical subsystems within the NCS are simulated and tested: a ship-steering system, an inertial navigation system, a global navigation satellite system, a periscope, sonar systems, and a plotting board. We expect that the proposed work will play a principal role when analyzing the behaviors and communications of defense CPSs and providing an environment for functional testing as a digital twin.
