KRI Amurang 581, a class of three LCUs (Dore, Amurang & Banten) produced by Korneuburg shipyard, Austria in 1968. This is the second time I saw a clear photo of the ship from this class. Nice find
Soko Galeb never inducted to Air Force service. It was bought as chaser airplane for N-250 programme and owned by IPTN.
The aircraft is not airworthy anymore because of the structural maintenance was pending and never carried out. It should be put into museum next to N-250.
