Ukraine Logistics Lockdown Campaign Quadruples Destruction of Russian Supply Routes With Middle-Strike Drones Disrupting Crimea Corridor

Analysis
Ukraine's drone campaign has imposed bridge-severance-equivalent denial through distributed attrition rather than a direct structural strike; civilian fuel bans and cancelled ferry services confirm effects the previous cycle assessed as emerging. A Kerch Strait Bridge closure exceeding 24 hours is unlikely before August 31, 2026. Ukraine's demonstrated ability to choke throughput through air defense suppression and fuel depot targeting removes the operational incentive to contest the crossing's concentrated defenses. Russia may partially offset attrition by accelerating railway diversion through Rostov and hardening convoy operations, restoring throughput faster than the current trajectory implies. High confidence rests on convergence across civilian rationing orders, commander-reported throughput data, and ISW damage assessments from independent channels, though those figures lack independent verification. NATO planners should calibrate toward drone production sustainment over bridge-closure contingency planning while distributed attrition remains the operative vector.
