And EOTS tested on Kizilelma PT-5:

Note the afterburner take-off
I have this feeling the "
S1" became PT-5 in the end...
EDIT: according to Defence Turkey Magazine, they flight tested the EOTS twice last week:
"The system, which was tested in two separate flight tests carried out at AKINCI Flight Training and Test Center in Çorlu last week, showed superior performance. In the tests,
stable image production at different altitude and speed regimes, long-range tracking stability on moving targets and high accuracy operation of laser targeting functions were successfully confirmed. It was observed that the system provides uninterrupted data exchange with Kızılelma's integrated mission computer and maintains its performance even in harsh environmental conditions. Test results also showed that all technical criteria that paved the way for the serial integration process were met."
