Two radomes providing strategic and theater missile warning for the United States and its international allies are photographed amid the autumn landscape on Oct. 19, 2021, on Buckley Space Force Base, Colo. Space Delta 4, the missile warning delta, contributes heavily to missile defense, space domain awareness, battlespace awareness and technical intelligence missions in support of Combatant Commanders. More than one thousand Guardians, Airmen, civilians, contractors, and allied mission partners execute the missile warning mission around the clock. (U.S. Space Force photo by Senior Airman Joshua T.
