Teluk Gilimanuk-class landing ship

The Teluk Gilimanuk class is a class of medium landing ship (LSM) that currently being operated by Indonesian Navy. They were originally built in East Germany for the Volksmarine as the Hoyerswerda class (NATO reporting name: Frosch I and II classes). These ships were acquired by Indonesian Navy in the 1990s.

Design
Teluk Gilimanuk or Hoyerswerda class consisted of two variants, the Project 108 (Frosch I) regular medium landing ship and Project 109 (Frosch II) combat support ship.

Project 108 (Frosch I) has a length of 98 m, a beam of 11.1 m, with a draught of 2.8 m and their displacement is 1,950 LT at full load. The ships is powered by two diesel engines, with total power output of 5,000 hp-metric distributed in two shafts.

Project 109 (Frosch II) has a length of 90.7 m, a beam of 11.1 m, with a draught of 2.8 m and their displacement is 1,700 LT at full load. The ships is powered by two diesel engines, with total power output of 4,408 hp-metric distributed in two shafts.

Both variants have a speed of 18 kn

They both have a complement of 46 personnel.

The Project 108 has a cargo capacity of 600 LT, while the Project 109 has a cargo capacity of 650 LT. They are equipped with a 5-ton crane amidships.

The ships were initially armed with two АК-725 twin 57 mm guns, complemented by two AK-230 twin barrel 30 mm guns for Project 108, and two 2М-3 twin 25 mm autocannons for Project 109. Some ships of Project 108 were also equipped with two 40-tube 122 mm rocket launchers. Both variants were also equipped with Muff Cob fire control radar. In Indonesian service, the Project 108 ships were rearmed with one single Bofors 40 mm L/60 gun, one twin V-11 37 mm L/63 guns, and two twin 2М-3 25 mm autocannons, while the Project 109 were rearmed with two twin V-11 37 mm L/63 guns and two twin 2M-3 25 mm autocannons.

Development
Twelve former German Democratic Republic fast medium landing ships (531 to 542) of the Project 108 (Frosch I) class were built by VEB Peenewerft, Wolgast, to an East German design, between 1976 and 1979. This class was named after the East German town of Hoyerswerda.

Logistic support ships of the Project 109 (Frosch II) class were built by the same shipyard as a development of the Frosch I landing ships. Originally commissioned in the Volksmarine on between October 1979 and February 1980.

Transfer
The Hoyerswerda class ships, and two support ships of the Project 109 (Frosch II) class, were officially transferred to Indonesian Navy, a on 25 August 1993. Refitted in German yards prior to transfer, where all armament was removed, to be replaced later by Indonesia after delivery.

The Hoyerswerda class ships were a valuable addition to the Indonesian Navy's landing forces in view of the block obsolescence of their, then current, LST Mark 3 landing ships, obtained from the United States. The LST Mark 3's were designed in 1943, and built before 1946. They were powered by steam engines.

After transfer to Indonesia, the two logistic support ships of the Project 109 (Frosch II) class were fitted with 37 mm guns, and with rocket launchers mounted forward of the bridge. They were commissioned 25 April 1995.

The Teluk Gilimanuk-class ships were bought on 3 September 1992 based on President Instruction No. 3/1992 that was issued by late President Soeharto. The procurement also included 16 Parchim-class corvette and 9 Kondor-class vessels worth a total cost of $482 million.

Operational history
Originally fourteen Teluk Gilimanuk-class LSMs were commissioned by the Indonesian Navy. All were built by VEB Peenewerft.

As of 2022 eleven ships are in active service, two were lost in accidents and one ship was retired.
