"818" previously served with the Royal Jordanian AF as "937" (US FY # 75-0621). Between 1979 and 1989, Singapore purchased 35 new single seat F-5E and 9 new dual-seat F-5F Tiger II in five batches. In addition, seven F-5E's were obtained 2nd hand from Jordan in 1994, bringing the total number of F-5's operated by the RSAF to 51. SQN 149 "Shikra" based at Paya Lebar stopped flying the F-5's in early 2010, just to start transitioning to the newly delivered McDonnell Douglas / Boeing F-15SG Strike Eagle on April 5, 2010.
