Air Force considers Selfridge to host international F-35 training center View Comments Washington — The Air Force is expected to decide soon on where to establish an international F-35 training center, and Selfridge Air National Guard Base in Harrison Township is among five candidates under consideration. Under the plan, the Air Force would house up to 36 F-35s at the base while the service trains international student pilots and support personnel from Singapore, Poland, Finland and Switzerland, said Phillip Ulmer, spokesman for the 127th Wing at Selfridge. Those nations would be purchasing the aircraft from the U.S. military. Other bases in the running to host the foreign military sales training center include Buckley Air Force Base in Colorado; Fort Smith Regional Airport in Arkansas; Hulman Field in Indiana; and Joint Base San Antonio-Lackland in Texas.
