The L 9531 class landing craft, also known as Type LCPR (Landing Craft Personnel Regional), [1] was a class of seven landing craft that were built by Rijkswerf Willemsoord for the Royal Netherlands Navy (RNLN). [2] During their service in the RNLN they were permanently stationed in Dutch New Guinea.

Design and construction

The L 9531 class landing craft were built between 1955 and 1956 at Rijkswerf Willemsoord in Den Helder, Netherlands. [1] [2] [5] They had a standard displacement of 55 tons and a complement of six. [2] When it came to measurements, the L 9531 class landing craft had a length of 25.25 meters, a beam of 4.50 meters and a draught of 1 meter. [1] Furthermore, they were equipped with two Kromhout 8 cylinder four-stroke diesel engines that could produce 200 shaft horsepower. [4] [2] [1] This could drive the two shafts to maximum speed of 10 knots. [2] As armament the craft had two 12.7 mm machine guns and two 7.62 mm machine guns. [4]

Service history

The L 9531 class landing craft entered into service of the Royal Netherlands Navy in 1955 and were permanently stationed in Dutch New Guinea. [3] [2]

Between 1955 and 1956 L 9531 was temporarily made available for hydrographic survey and research activities around Dutch New Guinea. [6]

In March 1962 it was reported that a L 9531 class landing craft was attacked near Gag Island by B-25 Mitchells of the Indonesian Air Force. [1] That same year the seven landing craft were taken out of service. [7] The following year, on 13 February 1963, they were decommissioned and transferred to the United Nations Security Force. [4]
