Press release said Embraer will modernize nine AF-1 single-seaters and three AF-1A two-seaters with new “navigation, weapons, power, tactical communications and sensor systems, plus computers and multimode state-of-the art radar.”
Brazil actually still operates their Skyhawks from their carrier. They also allow Argentina to occasionally operate aboard, using their own A-4AR Fightinghawk upgraded Skyhawks. One can’t help but come to the conclusion that these upgrades by Embraer are strongly influenced by the A-4AR.
12 planes is a pretty small fleet, but it is better than any other navy in the region, so they’ve got that going for them. Of course, the effectiveness of an upgraded aircraft is also directly tied to the weapons they carry. It will be interesting to see what the AF-1s carry in the future.
