Airman 1st Class Kyle Jacob, an aerospace propulsion Airman assigned the 509th Maintenance Squadron, poses for a portrait on July 9, 2019, at Whiteman Air Force Base, Missouri. Jacob and other members of the jet propulsion flight work daily to ensure the fleet of B-2 Spirits at Whiteman AFB have the engines needed to accomplish the mission, with plenty to spare, giving Whiteman the highest readiness rate across the active-duty Air Force.
