NEWPORT, R.I. – U.S. Navy undersea warfare experts needed automated test tools to help speed data and signal processing aboard modern ballistic-missile and fast-attack submarines. They found their solution from Systems Engineering Associates Corp. (SEA CORP) in Middletown, R.I.

Officials of the Naval Undersea Warfare Center Division in Newport, R.I., announced a $26.6 million five-year contract to SEA Corp. on Friday to develop the Extensible Markup Language Test Data Analysis Tool (XTDAS) to help verify and report data from submarine messaging, sonar, and launchers.

The XTDAS suite of automated test tools provides an automated method for collecting combat and weapon system message data, sonar data, and launcher data, and then analyzing and displaying the collected data in a format for data verification and reporting purposes, Navy officials say.

XTDAS also provides real-time automated data validation during laboratory, dockside, and at-sea testing, and helps integrate submarine non-propulsion electronics, weapon systems, and applications.

SEA Corp. will adapt XTDAS technology to collect and analyze submarine electronics and other combat and weapon system data for payload integration and testing that involves hardware and software, data collection, analysis, and data reduction.

SEA Corp. will use the XTDAS to provide subsystem integration and perform system, payload, as well as test for weapons compatibility, cyber security, software and hardware systems engineering, and submarine combat system electronics.

SEA Corp. also will adapt the XTDAS technology to support planning and preparation for the future Columbia-class ballistic missile submarine, which eventually will replace the Navy's Ohio-class missile boats.

On this contract SEA Corp. will do the work in Middletown and Newport, R.I.; Port Canaveral, Fla.; Andros Island, Bahamas; other contractor labs and facilities; and aboard submarines and test ranges, and should be finished by June 2025.
