A Sikorsky HH-60P Pave Hawk (01619) of the 6 Search & Rescue Group / 233 Combat Search & Rescue Squadron of the RoKAF of the Republic of Korea Air Force. Seen at Seongnam AB (RKSM, also known as K-16 and Seoul AB) During the 2011 SADE.
The ROKAF have begun using some of their Blackhawks in the CSAR role (note the badge on the engine cowling).
I really like this dark blue scheme that the Koreans use on their Blackhawks too.
