Submarine Open Systems Lifecycle, Risk & Technology Refresh Training by Tonex
Submarine electronic subsystems operate across long service lives while processors, software dependencies, and suppliers change much faster. This course examines lifecycle engineering for modular systems, with emphasis on obsolescence, risk prioritization, interface stability, qualification impacts, and carefully staged technology insertion. Participants evaluate alternatives for replacing computing components while preserving mission interfaces and supportability. Management attention focuses on developing useful refresh roadmaps, maintaining integrated baselines, and using evidence to distinguish manageable component changes from modifications that require broader requalification.
Cybersecurity exposure changes as components age and vendor support ends. Lifecycle planning strengthens cybersecurity by scheduling supported updates, assessing inherited vulnerabilities, and controlling the risks of replacement equipment and software.
The practical training approach includes exercises, real-world case studies, and examples of processes and documentation used in submarine acquisition and open architecture projects, including obsolescence registers, refresh roadmaps, lifecycle risk matrices, engineering change notices, and qualification impact assessments.
