This O-1C has BuNo 151776 and was delivered to the USN on 31 October 1963. The USN, however, never used this Bird Dog as it was immediately struck of charge the next day to be handed over to South Korea. This took place later in November 1963. For that reason it also received a USAF serial (63-12741), which was never carried on the aircraft. The South Korean Navy operated the aircraft under serial 51776. Since 2015, it is preserved at the gate of Pohang NAS as part of the 6th Air Wing collection.
