ICBM test contributes to continued deterrence
Missileers with the 321st Missile Squadron run through the test sequence document during the Simulated Electronic Launch-Minuteman test inside the launch control center at a missile alert facility in the 90th Missile Wing's missile complex, Neb., April 11, 2017. The missileers worked heavily in conjunction with missile maintainers to conduct a test of Minuteman III weapon system components. A SELM test proves the ICBM weapon system's effectiveness in a safe and secure manner. (U.S. Air Force photo by Staff Sgt. Christopher Ruano)
