Twentynine Palms Strategic Expeditionary Landing Field

Twentynine Palms Strategic Expeditionary Landing Field (ICAO: KNXP) is a military airfield located within Marine Corps Air Ground Combat Center (MCAGCC) Twentynine Palms, the largest Marine Corps base in the world by area. It serves as a tactical training and support airfield for the combat center, facilitating rotary-wing and fixed-wing operations in support of large-scale Marine Corps exercises. The airfield is not open to civilian commercial traffic and has no scheduled passenger service. It supports military transport, training, and expeditionary operations in the high desert environment of San Bernardino County, California. Its remote location and vast surrounding training ranges make it well-suited for realistic combat simulation exercises. Twentynine Palms hosts major joint and combined arms exercises such as Enhanced Mojave Viper and Integrated Training Exercise (ITX), which draw military units from across the United States and allied nations. The airfield plays a logistical and tactical role in these large-scale training events.
