KRI Pati Unus (384)

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, Ludwigslust was sold to the Indonesian Navy in 1995, alongside 15 other Kapitan Patimura-class corvettes and 23 other vessels in a US$12.7 million deal.

[3][4] On the 13 May 2016, the ship was partially sunk after her port side struck a shipwreck in shallow waters off Belawan, North Sumatra, Malacca Strait.
