This publication is the latest in a series of The IMEMO Sea Powers’ Rankings annual reports. Current issue contains results based on statistical data as of the 1st of January 2025. This assessment rests on a system of indexes, developed by Primakov National Research Institute of World Economy and International Relations (IMEMO) for evaluation of the overall maritime potential of nations. The Index of Maritime Might (IMM) is atop this system. The report includes the rankings of the top-100 countries according to their involvement in a variety of maritime activities (military, economic, science etc.). This issue contains an updated version (2.0) of these indexes.

The terms country, power, state and nation as used in this publication do not imply any judgment of the authors or of IMEMO concerning the legal status of any territory or the endorsement or acceptance of particular boundaries. These terms are used for research purposes only, as maritime statistical data for a range of geographically self-contained economic areas are maintained on a separate and independent basis.
