Building a Broadcast Simulator

Nathan built the first version of a broadcast simulator in React, then converted it to SvelteKit to improve performance and wrapped it in ElectronJS as a standalone executable. This allowed the application to run on older laptops within a closed-loop network. The simulator reproduced representative submarine message broadcasts used to train personnel in the processes that support delivery of mission-critical operational messages. The project joined domain expertise with application design and showed that software could preserve specialized knowledge, provide repeatable practice, and make training more accessible within constrained environments.

During Nathan’s second tour at SUBREADRON 36, personnel needed a practical way to rehearse the processes used to handle representative submarine message broadcasts within a closed-loop training environment.

The training capability had to provide realistic, repeatable practice while operating offline on older laptops and within constrained network conditions. A resource-heavy or externally dependent application would not meet the environment’s needs.

Nathan built the initial simulator in React, then migrated it to SvelteKit to improve performance and packaged it with ElectronJS as a standalone executable. He combined communications-domain knowledge with application design to reproduce representative training workflows without depending on external connectivity.

Effective training software must fit the environment in which learning occurs. Combining domain expertise with thoughtful platform choices can turn specialized operational knowledge into repeatable practice without requiring ideal hardware or connectivity.
