The military version of the Z-37T, armed with bombs and rockets, was almost forgotten. Its development in 1985 was apparently suggested by East Germany, but not proceeded with and the prototype soon became a regular Z-37T cropduster as OK-PJD. It ended up at Kaposvar, Hungary as a spares source. Restored in its original colours, it was unveiled on 24 June 2017 at the Kunovice museum.
