The 
incremental shutdown of F-22 production hit another milestone last week as workers at Lockheed Martin’s aircraft plant at Fort Worth, Tex., completed the final F-22 fuselage mid-section. They marked the occasion with a special send-off, draping the mid-section in the Texas flag before sealing it in its shipping container for the journey to Lockheed’s F-22 final assembly facility in Marietta, Ga. Fort Worth workers constructed a total of 195 mid-sections for F-22 development and production aircraft, reported the Fort Worth Star Telegram. With the mid-section production run complete as of May 12, the workers began dismantling the line. The Air Force’s final F-22—the last of 187 production airframes ordered—is due to roll off the Marietta assembly line this summer. Its delivery to the Air Force is scheduled for February 2012.
As Air Force leaders consider concepts of operations for Collaborative Combat Aircraft, sustainment in the field—and easing that support by using standard parts and limiting variants—should be a key consideration, according to a new study from AFA's Mitchell Institute of Aerospace Studies.
