Teluk Langsa-class tank landing ship

The Teluk Langsa-class tank landing ship was a class of tank landing ships which were operated by the United States Navy during World War II but were later transferred and sold to the Indonesian Navy in the 1960s and 1970s.

Design
The ships were all differently built on subclasses which were the LST-1-class tank landing ship and LST-542-class tank landing ship. Additionally, KRI Teluk Amboina was a copy of the LST-542 variant built by Sasebo Heavy Industries after World War II. There are ten ships in this class. KRI Jaya Wijaya was the half sister to these ships as she was converted to an Achelous-class repair ship.

Vessels of the class have a length of 328 ft, a beam of 50 ft, and a draft from 2 ft to 14 ft. Their displacement is 4,080 LT at full load. The ships are powered by two diesel engines with two shafts. The Teluk Langsa class has a speed of 12 kn.

The Teluk Langsa class has a capacity of 163 troops, 1900 LT of cargo, and two LCVPs on davits. The ships have a complement of 104 personnel, including 7 officers.

In 1980, it was stated that Teluk Amboina received an upgrade in weaponry, namely the installation of six Bofors 40/60 MK3 guns. As a landing ship, Teluk Amboina is equipped with four units of LCVP (Landing Craft, Vehicle, Personnel) and 20 medium tanks.

Fate
On 18 March 2011, Teluk Bayur was decommissioned and then sunk as target on 20 April. Teluk Langsa, Teluk Kau, Teluk Tomini and Teluk Saleh were simultaneously decommissioned on 3 May 2012 and scrapped in the same month.
