Key Highlights

  • SeaShield will analyze undersea warfare test data, including sensor outputs and telemetry, to evaluate system performance in operational environments.
  • The contract supports modeling and simulation tools to replicate undersea conditions and compare expected versus observed system behavior.
  • The five-year contract includes an option to extend through November 2031, increasing the total value to nearly $30 million.

NORFOLK, Va. - The Naval Supply Systems Command Fleet Logistics Center Norfolk in Norfolk, Va., has awarded SeaShield Technologies LLC in Suffolk, Va., a $27,041,424 firm-fixed-price, indefinite-delivery/indefinite-quantity contract to provide analytical operational test and evaluation support for the Navy’s Undersea Warfare Division 40.

Under the contract, SeaShield will support the Operational Test and Evaluation Force by analyzing performance data generated during undersea warfare test events. Work will be executed through task orders, with performance locations varying across U.S. ranges and overseas sites depending on test requirements.

The effort centers on analyzing undersea warfare test data, including sensor outputs, system performance logs, and operational test telemetry generated during evaluation events. The company will provide analytical support used to assess the effectiveness of undersea warfare capabilities in operational environments, including systems involving crewed and uncrewed undersea platforms.

Test scope

The scope includes support for test data evaluation and performance assessment workflows tied to undersea sensing, weapons testing, and uncrewed system experimentation. Rather than developing hardware, the contractor will focus on post-mission analysis, data reduction, and evaluation reporting used to inform Navy test and certification decisions.

SeaShield will also support modeling and simulation-based analysis, including tools used to replicate undersea operating conditions and compare expected versus observed system performance. These environments are typically used to evaluate system behavior under variable oceanographic and operational conditions and to support structured test reporting.

The contract includes a five-year ordering period beginning in May 2026 and continuing through May 2031. A six-month option period under Federal Acquisition Regulation 52.217-8, if exercised, would extend ordering through November 2031 and increase the total estimated value to $29,921,764.

Fiscal 2025 Navy research, development, test, and evaluation funds in the amount of $2,500 will be obligated at award and will expire in September 2026. Subsequent task orders will be funded with applicable fiscal year RDT&E appropriations, depending on issuance timing and program requirements.

Undersea modeling 

SeaShield will also support modeling and simulation-based analysis, including tools used to replicate undersea operating conditions and compare expected versus observed system performance. These environments are typically used to evaluate system behavior under variable oceanographic and operational conditions and to support structured test reporting.

Because the work supports operational test and evaluation activities, SeaShield will operate within secure Navy data environments, processing controlled test information used to assess system performance and mission effectiveness.

The contract includes a five-year ordering period from May 2026 through May 2031. A six-month option period under Federal Acquisition Regulation 52.217-8, if exercised, would extend ordering through November 2031 and increase the total estimated value to $29,921,764.
