The Tarlac-class is a ship class of landing platform docks, based on the Indonesian Navy Makassar-class, that will be commissioned under the Philippine Navy. Two ships were ordered and constructed by the Indonesian state-owned shipbuilder PT PAL (Persero).[3] The lead ship was launched on 17 January 2016[4] as BRP Tarlac (LD-601).[5] The class was initially called the "Strategic Sealift Vessel" before the class was formally named.

Construction of the first unit already started in January 2015 and is expected to be delivered by July 2016, while the second unit will start a few months after and will be delivered by the 2nd or 3rd quarter of 2017.[6] These ships would be the first of its kind to be operated by the Philippine Navy, and are meant to be used for amphibious operations and transport duties in support of the Armed Forces of the Philippines, but will double as a support platform for Humanitarian and Disaster Relief (HADR) and Search & Rescue (SAR) operations.

Design

The design is closely based on the Makassar class of Landing Platform Dock used by the Indonesian Navy, which in turn were actually based on a low-cost LPD design from Korean shipbuilder Daewoo Shipbuilding and Marine Engineering / Daesun Shipyard.

Communication Equipment

The communication equipment is supplied by the Portuguese company EID Naval Communications specifically the ICCS5 communications control system, and Harris RF Communications VLF-HF and V/UHF radios.[7]

Propulsion

The ships have a Combined Diesel and Diesel (CODAD) layout and will be using similar engines as those used by their Indonesian counterparts, the MAN 9L28/32A medium speed engines. Combined power from the two engines will produce 7,830 bhp transferred to two controllable pitch propellers.[8][2]

Armaments

PT PAL confirmed that the SSVs will be designed to support one 76 mm gun on the foredeck as the main armament. Two stern-facing 25 mm guns will also be fitted, one each on the port and starboard sides.[9]

The weapons systems will be installed separately by the Philippine Navy after delivery.

Flight Support

Originally the ships were designed with a hangar and helicopter landing deck for two medium-sized helicopter, with the specifications emphasizing the US-made Sikorsky Black Hawk helicopter as basis. But changes in the Philippine Navy's requirement later on changed the design to have a hangar for two medium helicopters.

Construction

SSV-1 officially started its construction on January 22, 2015 where a 1st steel cutting ceremony was held in PT PAL's facility in Surabaya, Indonesia.[10] It has entered keel laying works as of June 5, 2015, and was launched as BRP Tarlac (LD-601) on January 18, 2016. Further works and testing will be made until the ship is delivered to the Philippine Navy by May 2016.[11][12]

The second ship, SSV-2, has undertaken its first steel cutting ceremonies also on June 5, 2015 in PT PAL's Surabaya shipyard.[12] It's keel laying ceremonies was held together with the launching of the lead ship on January 18, 2016, and was given a hull number LD-602. It is expected that the ship will be delivered to the Philippine Navy by May 2017.[11]
