Along with Walker Army Air Field near Victoria, Great Bend Army Air Field near Great Bend and Smoky Hill Army Air Field near Salina, the initial cadre of the 58th Bombardment Wing was formed. The 58th Bomb Wing was the first B-29 combat wing of World War II and engaged in the first long-range strategic bombardment of the Japanese Home Islands beginning in March 1944 from bases in India.
