Manufactured around 1977, 30145 entered service as a J-20 (Yugoslav Air Force designation of the P-2). The specific history of it is currently unknown but the J-20 was phased out of operational service in 1989. This one ended up in the storage area of the Muzej Vazduhoplovstva Beograd where it was first noted in Aug-2003. It is carrying Serbian Air Force markings, but it is assumed that these markings were painted in the museum as the Serbian AF only exists from 2006.
