The 39th and final B-52G Stratofortress, tail number 58-0224, right, accountable under the New START Treaty (Strategic Arms Reduction Treaty) with Russia, lies in the 309th Aerospace Maintenance and Regeneration Group boneyard at Davis-Monthan Air Force Base in Tucson, Ariz. on Thursday, May 21, 2015.

The tails are angled at 30 degrees so Russian satellites can view compliance. Tail number 58-0224, nicknamed “Sweet Tracy”, flew combat missions over North Vietnam in Operation Linebacker II, which began Dec. 18, 1972 and lasted 11 nights.
