Israel has neglected its trainers for a while, I think that their Fouga Magisters were retired as primary trainers only a few years ago, and that they still use the A-4 Skyhawk as an advanced trainer, so it comes as no surprise that the IAF has done some test flights in the supersonic T-50 trainer.
They are also looking at the BAE Hawk and the (also supersonic, but barely) Aermacchi M-346, which ironically started as a Russian design.
Still, it’s $25 million a pop for the T-50….Great googly moogly.
