South Korea readies KF-21 operational rollout as F-5 retirements target end-2027; Malaysia MRCA race starts toward 2029–30 repla
South Korea’s Air Force is preparing for KF-21 deployment while planning to retire its aging F-5 fleet by the end of 2027—though cost overruns could delay timelines. Separately, Malaysia is expected to assess a new MRCA program in 2029 or 2030 to replace its F/A-18D Hornets and Su-30MKM, setting up a competitive field including KF-21, Su-57E, Rafale and Gripen.
