History

In 2019, Indonesia's military development policy entered its third phase within the Minimum Essential Force (MEF) Policy framework. One of the MEF requirements for the Indonesian Navy includes the provision of hospital auxiliary ships.^[2][3]

Before the Sudirohusodo-class, the Indonesian Navy already used two hospital ships; KRI dr. Soeharso (990) in active service since 2003; and KRI Semarang (594) in active service since 2019. However, both ships were initially designed and built as the Landing Platform Dock (LPD), where KRI dr. Soeharso was re-designated to became a multi-purpose hospital ship in 2007;^[4] while KRI Semarang was assigned to be an auxiliary hospital ships for temporary, due to her main function and purposes being supposed to be the addition of Landing Platform Dock for the Indonesian Navy.^[5] Therefore the Indonesian Navy needed another ships that were designed and built from the start specifically for hospital ship purposes, that are mobile and can be moved anytime to the disaster affected areas to carry out disaster emergency response, and for other humanitarian activities.^[6][7]

The first steel cutting of the lead ship in the class was carried out on 9 July 2019 at PT PAL shipyard in Surabaya.^[8] As per June 2024, all ships in the class has been repainted white by PAL in accordance with the IV Geneva Convention and The San Remo Manual on International Law Applicable to Armed Conflicts at Sea.^{[9][10][11][12]}

Design

The Sudirohusodo-class uses the same general hull design as that of the Indonesian Navy's Makassar-class landing platform docks. It has a length of 124 metres, beam of 21.8 metres, and displacement of around 7,290 tonnes. A pair of 5,420kW main engines could propel the hospital ship to a speed of 18 knots. With cruising speed 12 knots it can reach range of 10,000 nautical miles or a maximum endurance of 30 days, ensuring sustained sea-based medical support for deployed Indonesian forces as well as civilians in need. Like the Makassar-class which is based, the ship is also designed to have a flight deck for two helicopters and a hangar for one helicopter to support the air transportation or air medical evacuation purposes.^[13][14]

Modifications to allow the ship to perform the floating hospital role include the removal of all armament, also the removal of well deck with its stern gate/ramp to accommodate the medical infrastructure and facilities inside the ship, in order to increase the capacity and capabilities related to her role as hospital auxiliary ship.^[15]

Due to the nature of big ship requires time for docking and undocking, the ship is also designed with evacuation-at-sea infrastructure on the port and starboard to accommodate the davit system with its evacuation-at-sea equipments; such as ambulance boats, LCVP and RHIB; speeding up the evacuation-at-sea process from and to the hospital ship.^[13][14]
