Operational Capability/Readiness Effectiveness Assessments

For over 30 years, PURVIS played a key role in all facets of the effectiveness measuring exercise programs for Anti-Submarine Warfare (ASW) and Mine Warfare (MIW)

Assuring Warfare Readiness

The military has long recognized the value in providing early feedback and evaluation of effectiveness and suitability of a system to

  1. identify defects, gaps, and areas of risk,
  2. establish additional training requirements, and
  3. assess the reliability of the operations and warfighting capability.

These assessments include the collection and analysis of system performance, environmental, and geographic data in tactically relevant environments, performance of scenarios to assess ship warfare readiness and effectiveness, and recommended solutions for identified warfighting gaps.

PURVIS has performed Operational Capability Assessments for over 30 years, evaluating operational effectiveness and operational suitability. The focus of these assessments is on significant trends noted in development efforts, programmatic voids, risk areas, adequacy of requirements, and the ability of the program to support adequate operational testing.

Our expertise includes:

Planning & Design

  • Planning, executing, observing and reconstructing complex at-sea readiness effectiveness measuring exercises.
  • Preparation of post-exercise technical reports that formed the basis for warfighting tactics, techniques, procedures and system acquisition decisions.
  • Successful translation of lessons learned adapted from the Ship Anti-Submarine Warfare Readiness Effectiveness Measuring (SHAREM) process into the Mine Readiness Effectiveness Measuring (MIREM) exercises from 1997-2008, and the Surface Warfare REM or SURFREM pilot exercise in the fall of 2010.
  • Designed large-scale at sea trials for the Naval Warfare Development Command’s to test and evaluate new warfighting concepts via the Fleet Experimentation (FLEX) Program.

Improvements & Modernization

  • Process improvements in exercise reconstruction and analysis that afford tactical commanders rapid feedback of exercise results.
  • A quantum improvement in Anti-Ship Torpedo Defense tactics that directly affect class specific ship survivability.
  • Modernization of the existing REM database to match industry standards as well as extending the applicability of the database to all candidate SURFREM warfare areas, and subsequently interfacing that data to a variety of computational, analytic and visualization tools.


  • Execute Joint and NATO Concept and Capability development and Experimentation.
  • Develop/review Experimentation Design Documents and Data Analysis/Collection Plans to ensure that experiments/exercises properly support and attain stated objectives.
  • Draft/update Tactics, Techniques, and Procedures (TTP) Publications for operators and tacticians.
  • Testing of advanced prototype systems and promising technologies under the Navy’s Undersea Warfare Employment of Emerging Technology (USWEET) program.
