Thanks, it became clearer. But what happened to the L-15 (LIFT) and L-15B? And what kind of varinat - L-15 WRZY?
That's actually a good and still open question. AFAIK the LIFT is still on offer for export as the L-15B, then there is also a carrier-capable variant called JL-10J rumoured since some time and the L-15WRZY is a dedicated test plane for drone development.
