An An-2 of the Korean People's Army Air Force apparently employed for nocturnal penetration of South Korean airspace (agent transportation) in 1984. Note overall black finish with black background to national markings.
An An-2V used by the air element of the Polish Navy, the Morskie Lotnictwo Wojskowe, for coastal patrol tasks in the Baltic. Several civil and military floatplane versions of the An-2 have been developed.
The An-3 is essentially a turboprop conversion of the An-2 embodying modernised systems, and An-2s are reportedly being converted to An-3 standard at a plant in Kiev, some fuselage components being produced in Poland by WSK-PZL Mielec.
