Boeing Defense and a machinists union have reached a tentative deal to end a five-week-long strike in the St. Louis area, union officials said on Sept. 10.
Workers at Boeing’s St. Louis facilities produce F-15 and F/A-18 fighter jets, the T-7A Red Hawk trainer, and various advanced weapons systems for the US military.
