The increased frequency of PLAAF/PLANAF probing flights (which frequently consist of various Y-8-based reconnaissance aircraft and H-6 bombers rather than Su-27-based fighters) around Taiwan have gotten some local enthusiasts thinking of a cheap-to-operate, maybe high-endurance stalker aircraft to monitor the large reconnaissance or bomber planes and by extension save airframe hours of F-CK-1s and F-16s for those flown with actual fighters.
Which reminds me of the HU-25C Guardian (incidentally, ROCAF would likely have quite a few surplus APG-66V(3) lying around upon the conclusion of the F-16V project)...... although I surmise that the platform has to be able to keep up with the cruise speed and service ceiling of the H-6K.
The Embraer Phenom 100 is mentioned in one of those discussions in comparison against the Textron Scorpion...... although so far I like the Phenom 300 better. The H-6K can outrun all three at top speed, but the Phenom 300 at least has a higher cruise speed, and the available internal space can be converted into more internal fuel. Having said that, neither version of the Phenom appears to have room in the nose for a radar.
Comments and suggestions would be appreciated.
