A U.S. Marine Corps F-35B Lightning II aircraft with Marine Fighter Attack Squadron (VMFA) 214, Marine Aircraft Group 13, 3rd Marine Aircraft Wing, taxis the runway during suppression of enemy air defense training in support of Exercise Steel Knight 23.2 at Marine Corps Air Station Yuma, Arizona, Dec. 7, 2023. SEAD training increases the ability of fifth-generation fighter pilots to enter the fight first, strike targets deep within an enemy air defense system, and enable follow on strikes by supporting weapons platforms. Steel Knight 23.2 is a three-phase exercise designed to train I Marine Expeditionary Force in the planning, deployment and command and control of a joint force against a peer or near-peer adversary combat force and enhance existing live-fire and maneuver capabilities of the Marine Air-Ground Task Force.
