B-2 Avionics
Airmen 1st Class James Lott and Michael Maluk, 509th Maintenance Squadron avionics back shop team members, remove and replace the back shell on a cannon plug at Whiteman Air Force Base, Mo., July 25, 2013. Stress over time, as well as normal wear, can cause back shells to break, requiring removal and replacing. (U.S. Air Force photo by Airman 1st Class Keenan Berry/Released)
