Having already operated twenty F-5's of various versions since the mid 1970's, the Royal Malaysian AF in 1980 became the launch customer for the rare RF-5E Tigereye, of which two were added to the TUDM (Tentera Udara Diraja Malaysia) fleet in 1983. Assigned to SQN 12 "Scorpions" at Butterworth, they were serialled M29-19 (US FY # 80-0333) and M29-20 (80-0334). Before getting the M29-xx serials, Malaysia's F-5's carried FM-22xx codes. Also in the early 1980's, two F-5E and a single F-5F were ordered as attrition replacements, bringing the total number of F-5's operated by the RMAF to 25.
