There has been mention of RMAF F-16s, only it appears their small but diverse fleet of combat aircraft includes Sukhoi Su-30s, F/A-18Ds and some Mig-29s. As recently as last year a sum of US$100 million was allocated to improving the Su-30s combat readiness from 65-70percent to 80percent or more.
Such data suggests the RMAF takes its role as providing aerial defence and airspace dominance of Malaysian airspace and territory seriously.
From my experience of Malaysia and the RMAF, so long as it happens between 0930 and 1630 hrs Monday to Friday.
