Global Security and Defense Developments - 17 March 2026

Executive Summary

The United States has escalated its air campaign against Iran through sustained high-tempo operations, with more than 6,000 combat sorties conducted since the start of Operation Epic Fury. Forward-deployed B-1B bombers from RAF Fairford are actively participating in strike missions, while additional assets including F-35A fighters and E-2D Advanced Hawkeye aircraft are being deployed to strengthen air superiority and airborne early warning capabilities. The shift toward E-2D platforms reflects operational gaps identified in legacy AWACS systems against low-signature drone threats. At the same time, logistical airlift operations and adjusted aerial refueling routes highlight ongoing efforts to maintain operational continuity despite risks in Iraqi airspace. The operational focus remains on degrading Iran’s air defense and strike capabilities. U.S. forces are conducting SEAD and DEAD missions targeting radar and early warning systems along Iran’s southern coastline, particularly around the Strait of Hormuz, while also striking anti-ship missile deployments. Israeli operations complement this effort through continued deep strikes against missile storage facilities and sustained pressure on Hezbollah-linked targets in Lebanon. Iran, in response, has adapted its approach by reducing salvo sizes and shifting toward more precise ballistic missile usage, alongside persistent low-intensity drone attacks aimed at stressing U.S. air defense systems. The maritime domain is becoming increasingly contested, with the Strait of Hormuz remaining a critical pressure point. U.S. mine countermeasure operations have intensified amid assessments that Iran maintains ready mine-laying capabilities and pre-positioned stockpiles. While large-scale mining activity has not been confirmed, incidents involving suspected limpet mines or unmanned surface systems, along with attempted UAV attacks on commercial vessels, indicate a sustained hybrid maritime threat. Shipping patterns are already affected, with rerouting of tankers, increased transit times, and rising insurance costs contributing to reduced commercial activity.
