Aiming at the special equipment support environment, complex task requirements, and insufficient scientificity of existing evaluation methods of the China Coast Guard (CCG), this study takes a directly affiliated bureau of the CCG as the research object to construct a targeted equipment support capability evaluation system. The Analytic Hierarchy Process (AHP) is adopted to determine index weights, and the fuzzy comprehensive evaluation method is integrated to establish an evaluation model. Empirical evaluation is conducted through field investigations, questionnaires, and statistical data collection. The results show that the comprehensive score of the bureau’s equipment support capability is 3.32 points, reaching a “general” level. Among the five criterion layers, support resource allocation and support personnel quality perform relatively well, while support technology level and support management mechanism need further optimization. This evaluation system is scientific and feasible, providing theoretical support and practical reference for the refined management and systematic improvement of the CCG’s equipment support capability, which is in line with the construction requirements of the modern military equipment management system.
