Also in the article..."The F-5 has no beyond-visual-range [BVR] capability," the source said. "In today's environment, it is nothing but a target. The modern Chinese fighters could track and kill an F-5 before it is aware of the threat."
F-5 with an improved radar maybe BVR. The nose cone limits the size of the dish though.
More importantly with its small size, it can carry 2 Amraam and cold launch? This will spring a very nasty trap.
We have advanced F-16 C/D no need to upgrade.
The APG-80 aesa radars for the F-16s sure look tempting....
Our F-5S r AMRAAM capable
More specifically our F-5S' radars are AMRAAM compatible. Whether the aircraft are capable a not requires a bit more than radar.
