KRI Untung Surapati (372) is a Kapitan Pattimura-class corvette currently operated by the Indonesian Navy.
The Parchim-class corvette was developed for the East German Navy in the late 1970s, and built by the Wolgast Peene-Werft.
In case of an all-out NATO-Warsaw Pact war in Europe their prime targets would have been the small U-206 coastal submarines of the West German navy.
To make production more economical, the Soviet Union agreed to purchase another 12 ships from Wolgaster Peenewerft built between 1986 and 1990, thereby effectively subsidising the East German shipbuilding industry.
[2][3] Following the end of the Cold War and the reunification of Germany, Ribnitz was sold to the Indonesian Navy in 1993, alongside 15 other Kapitan Pattimura-class corvettes and 23 other vessels in a US$12.7 million deal.
