Boeing Co. plans to shutter operations in Wichita, Kansas, where it has built airplanes since 1929, by the end of 2013 as military projects dry up amid U.S. spending constraints.

Job reductions at the plant that employs (BA) more than 2,160 workers will begin in the third quarter of 2012, Boeing said in a statement today. Work on the aerial-refueling tankers the Pentagon ordered in February will be done at the planemaker’s wide-body jet factory in Washington state instead, and some existing work will be moved to Texas and Oklahoma.
