NEWPORT, R.I. – U.S. Navy undersea warfare experts needed test and measurement tools for U.S. Navy submarine electronics, sensors, navigation, and communications systems. They found a solution from System Engineering Associates Corp. (SEACORP) LLC in Middletown, R.I.

Officials of the Naval Undersea Warfare Center in Newport, R.I., announced a $29.5 million contract to SEACORP on Wednesday for the Extensible Markup Language (XML) Test Data Analysis Tool (XTDAS) project.

Under these awards, SEACORP will continue developing the XML XTDAS automated test-tool technology, which automates the collection of combat and weapon system message data, sonar data, and launcher data, and then analyzes and displays the data in a verifiable reporting format.

XML XTDAS provides real-time automated data validation during testing, and helps integrate disparate submarine subsystems, weapons, and applications. It involves submarine non-propulsion electronics; weapons systems; sonar; combat control; external communications; imaging; electronic warfare (EW); navigation; and testing.

Submarine testing

XML XTDAS will help direct the conduct of system performance, certification, calibration, and developmental testing for the future Columbia-class ballistic missile submarine and the Virginia-class (SSN 774) fast-attack submarine.

SEACORP will develop, upgrade, and adapt XTDAS to collect and analyze submarine non-propulsion electronics and other combat and weapon system data for payload integration and test and evaluation. XTDAS development includes hardware and software for integration, data collection, analysis, and data reduction.

In 2020 SEACORP won a $26.6 million five-year contract to develop the XML XTDAS submarine system test and measurement tools to help verify and report data from submarine messaging, sonar, and launchers.

Submarine testing can involve weapons systems, submarine warfare federated tactical systems certification, weapons compatibility, sensor accuracy, cyber security, and array calibration. The XML XTDAS will help the Navy make the most of submarine advanced data processing with automated test tools for test data analysis.

The Navy will develop and maintain different XTDAS hardware and software variants for each new generation of on-board computers aboard each class of U.S. submarine systems hardware and software.

The Navy will use the XTDAS tool for developmental and operational test planning for all U.S. submarines. SEACORP will use XTDAS to provide subsystem test, evaluation, integration, system engineering, technical, and XTDAS support services.

XTDAS will help the Navy test submarine system-level electronics, payloads, weapons compatibility, cyber security, software and hardware, systems integration, and certification during new construction and at test sites.

Planning for Columbia submarine

SEACORP also will adapt XTDAS for planning and preparation for Columbia Class test programs; provide XTDAS installation and removal; support testing; establish and manage the XTDAS test database; maintain XTDAS configuration management; and maintain and store XTDAS equipment.

On this contract, SEACORP will do the work in Middletown and Newport, R.I.; Port Canaveral, Fla.; and Andros Town, Bahamas.
