Specifications

The Parchim-class corvette was developed for the East German Navy in the late 1970s, and built by the Wolgast Peene-Werft. The ships were designed for coastal anti-submarine warfare. 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. The first ship, Wismar (now the Indonesian KRI Sutanto), was launched on 9 April 1981 in Rostock, and subsequently another 15 ships were built until 1986. 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.

The ships of the Soviet Navy were named Parchim II by NATO. Though useful as a coastal ASW platform, the Soviet production of the similar but far more powerful Grishaclass made this purchase even more illogical for the Soviet Navy. After German re-unification the former East German ships were sold to the TNI-AL (Indonesian Navy) in 1993. The Indonesian Navy extensively refurbished their Parchims, to the point where the refurbishing exceeded the cost of purchase. They are still in service, both in the Indonesian Navy and in the Russian Baltic Fleet.

Indonesian Parchims have completed a major refit to fulfill Indonesian Navy needs. [1] The one twin 57 mm gun AK-725 and one twin 30 mm gun AK-230 were retained except for KRI Sultan Thaha Syaifuddin where the 30mm AK-230 replaced by Chinese made Type 730 CIWS. The RBU-6000 also retained as a major armament. Two SA-N-5 SAM removed and replaced by two Vektor G12 20mm gun. [1] [2] Four 400mm Russian-made torpedo launcher was out of service because there is no Russian made torpedo in Indonesian Navy inventory so this Russian made torpedo launcher replaced by two western made triple torpedo launcher but only for two ships.

Service history

Perleberg was commissioned on 19 September 1981. [3] [4] Following the end of the Cold War and the reunification of Germany, Perleberg was sold to the Indonesian Navy in 1994, alongside 15 other Kapitan Patimura-class corvettes and 23 other vessels in a US$12.7 million deal. She was renamed Wiratno and was commissioned on 19 September 1994, following modifications. [4] [5]

Libyan Navy Military unit

Libyan Navy is the branch of the Libyan military responsible for naval warfare. Established in November 1962, Libyan Navy has been headed by Admiral Mansour Bader, Chief of Staff of the Libyan Naval Force. Before the Libyan Civil War it was a fairly typical small navy with a few missile frigates, corvettes and patrol boats to defend the coastline, but with a very limited self-defence capability. The Navy has always been the smallest of Libya's services and has always been dependent on foreign sources for equipment, spare parts, and training. Most of the Gaddafi era fleet was destroyed in 2011. Since the start of the ongoing internal conflict, the Libyan Navy is aligned with the Government of National Accord (GNA), led by the Presidential Council in Tripoli, apart from coastal patrol vessels under the control of the Libyan National Army.
