The Navy’s Undersea Warfare Decision Support System (USW-DSS) uses data from an ever growing number of sensors, accessible through an equally growing number of Application Programming Interfaces (APIs). Due to the lack of standardization among these sensors and APIs, as the system has continued to grow, the challenge of collecting and using these data has become increasingly prevalent. Previous work at Michigan Tech, in collaboration with engineers at ARiA (Applied Research in Acoustics LLC), introduced a GraphQL Mesh federated API gateway. The gateway would enable the combination of diverse API sources into a predefined hierarchical structure. This report follows the continued implementation of this gateway, focusing on its structure, the implementation of its Graphical User Interface to facilitate development utilizing the gateway, and the challenges faced along the way. Ultimately, we successfully implemented the GraphQL Mesh federated API gateway, though we note that there still exists room for future work.
