The analysis that half of the aircraft are capable of effectively engaging the enemy isn't really a dig against aircraft readiness rate but rather aircraft capability. The F-16s, all upgraded to V standard, are no doubt very potent and form half of the ROCAF fleet but the rest consist of F-CK-1, Mirage-2000, and F-5. F-5 are obviously obsolete. Mirage-2000 operated by Taiwan, due to supplier issues with France, has not been modernized properly and has no EW capability to speak of. The AAMs acquired for the Mirages are also past their expiration date and ROCAF pilots try to remedy the situation by carrying a full load whenever they scramble for intercept, their logic being that at least a few of them are still operational. F-CK-1 does have EW capability and can carry domestic weapons, but they are very small and their engines barely produce enough power to keep the avionics operational. A ROCAF pilot commented during a podcast that the EW pods can drain the power very quickly and are not very practical. Even though I enjoy dunking on PLAAF's and PLANAF's legacy flankers, all of them are, in fact, capable of carrying effective EW payloads. The Su-27SK, as a matter of fact, can even the odds against the J-10A and J-11B somewhat by using EW. The R-77/R-73, even though outdated, are still functional missiles. This makes the legacy flankers competitive fighter aircraft against anything that isn't a F-16V in the ROCAF arsenal.
