Green Flag (exercise) is a recurring large-scale air combat training exercise conducted principally by the United States Air Force and allied air forces to replicate high-intensity conflict conditions and joint force integration. The event emphasizes realistic contested environments, integration with ground and maritime units, electronic warfare, and multi-domain command and control to prepare participants for expeditionary operations and coalition warfare. Green Flag draws participants from a wide range of NATO, Five Eyes, and partner nations and regularly interfaces with major commands, numbered air forces, and service components across the Department of Defense.
Green Flag originated to address lessons from Operation Desert Storm, Operation Enduring Freedom, and Operation Iraqi Freedom by creating a managed, high-fidelity training environment that simulates contested airspaces and integrated air operations. The exercise serves to validate concepts developed by Air Combat Command, United States Central Command, and United States Northern Command while supporting readiness frameworks used by U.S. Strategic Command, NATO Allied Command Transformation, and partner organizations. Planners coordinate with institutions such as Air Force Doctrine Center, Joint Staff, Air University, and Nellis Air Force Base-based entities to align Green Flag events with joint capability development and operational testing programs. The purpose includes stress-testing tactics promulgated by U.S. Navy Warfare Development Command, Marine Corps Warfighting Lab, and coalition equivalents from Royal Air Force, Royal Australian Air Force, and other allied services.
Participating formations include units from United States Air Force, U.S. Army, United States Navy, United States Marine Corps, and allied air arms such as Royal Air Force, Royal Canadian Air Force, Royal Australian Air Force, French Air and Space Force, German Air Force, Italian Air Force, and Spanish Air Force. Coalition participants range from NATO members like Poland and Turkey to partners including Japan, Republic of Korea, Israel, and United Arab Emirates when deconflicted with regional authorities such as U.S. Central Command and host nations. Training also integrates elements from Air National Guard, Air Force Reserve Command, Military Sealift Command, Strategic Airlift Capability, and multinational units associated with European Air Transport Command and Allied Rapid Reaction Corps.
Green Flag incorporates live-fly missions, simulated sorties, electronic warfare scenarios, and combined arms coordination among units representing strike, air superiority, suppression of enemy air defenses, intelligence, surveillance, reconnaissance, and aerial refueling. Components include deployments of fighters such as Lockheed Martin F-22 Raptor, Lockheed Martin F-35 Lightning II, Boeing F-15E Strike Eagle, Boeing F/A-18E/F Super Hornet, and unmanned systems like General Atomics MQ-9 Reaper. Support elements include Boeing KC-135 Stratotanker, Boeing KC-46 Pegasus, airborne warning systems like Northrop Grumman E-3 Sentry, electronic attack platforms such as Boeing EA-18G Growler, and surface-to-air systems emulated by opposing force units. Command and control integration leverages networks tied to Joint All-Domain Command and Control, Link 16, Advanced Battle Management System, and allied interoperability standards promulgated by NATO Standardization Office.
Green Flag events occur multiple times per year at locations including Nellis Air Force Base, Eielson Air Force Base, Davis-Monthan Air Force Base, Joint Base Elmendorf-Richardson, and test ranges such as Nevada Test and Training Range, White Sands Missile Range, and Utah Test and Training Range. Iterations have expanded to European and Pacific theaters in coordination with United States European Command and United States Indo-Pacific Command planning cycles. Timelines are synchronized with major exercises like Red Flag, Maple Flag, Talisman Sabre, RIMPAC, and Trident Juncture to provide complementary training opportunities and multinational interoperability assessments.
Training objectives emphasize suppression of enemy air defenses, integrated air interdiction, close air support coordination with U.S. Army, maritime strike integration with United States Navy, and coalition command relationships under Combined Joint Task Force constructs. Tactics practiced include standoff engagements, low-observable mission profiles, electronic warfare employment, cyber-electromagnetic activities linked to U.S. Cyber Command scenarios, and contested logistics. Techniques under evaluation include distributed operations, agile combat employment, and cross-domain fires coordination informed by doctrine from Office of the Secretary of Defense, Joint Chiefs of Staff, and service warfighting laboratories. Metrics for success align with readiness reporting used by Combatant Commands and force generation models associated with Air Force Global Strike Command and allied readiness frameworks.
Notable iterations have validated integration of fifth-generation fighters into large-force employment, improved coalition routing for tanker support, and refined suppression of enemy air defense tactics based on lessons from Operation Inherent Resolve and NATO collective defense exercises. Outcomes include doctrinal updates adopted by Air Combat Command and allied air arms, procurement decisions affecting platforms like F-35, KC-46, and electronic warfare suites, and enhanced interoperability agreements among NATO members formalized at meetings of the NATO Defense Planning Committee and NATO Military Committee.
Criticism has focused on environmental impacts at training ranges, noise concerns raised by communities near Nellis Air Force Base and Davis-Monthan Air Force Base, and the fiscal cost of large-scale exercises debated in hearings of United States Congress defense committees. Other controversies include export-control tensions when integrating partner systems, airspace deconfliction with civil aviation authorities represented by Federal Aviation Administration, and geopolitical sensitivities when exercises involve nations with complex regional relationships overseen by U.S. Department of State and allied diplomatic channels.
