Multipurpose Assault Craft. The Multi-Purpose Assault Craft (MPAC) is a type of fast attack assault craft developed for the Philippine Navy. Originally designed to transport troops at a high speed and then land them on the beach, they have since expanded their roles to include interdiction, surface warfare, and search and rescue.

A total of 42 boats are planned to be built by the Navy of which 12 have been completed as of September 2019. The Mk 3 version of the MPAC are the first boats in the history of the Philippine Navy to be officially armed with missiles.

Design 
The MPAC's hull is made out of aluminum alloy and is powered by water jet engines. It has a range of , a maximum speed of 40–47 knots, and carries a crew of 5–7 plus 8–16 fully equipped soldiers.

The Mk 1 and Mk 2 can deploy an assault ramp at their bow while in later versions this feature was removed.

Construction 
In 2009, the Philippine Navy ordered the first batch of three ships from Taiwanese company Lung Teh Shipbuilding Co. Ltd. These first three ships were commissioned into service during the Philippine Navy's 111th Anniversary on May 22, 2009. These boats are designated the Mk 1 version.

In 2011, an additional three MPACs were built that were slightly bigger than the previous three ships.  These ships this time were built by the Filipino company Propmech Corp. Designated as Mk 2.  The first of these second batch of MPACs was commissioned into service during the Philippine Navy's 114th Anniversary on May 22, 2012. The next two ships were commissioned on August 6, 2012.

In 2016, Propmech was again contracted to build another three ships for US$1.86 million (PHP 90 million) each and delivery was set for April 2017. The ships, designated as Mk 3 versions,  arrived without their armaments and were commissioned into service on May 22, 2017 as part of the Philippine Navy's Third Boat Attack Division of the Philippine Fleet's Littoral Combat Force. The armaments for the Mk 3 were initially set to be delivered by December 2017, but were only actually delivered in May 2018.

In September 2017, the Department of National Defense (DND) released a tender to procure an additional three MPAC vessels based on the Mk 3 platform which will be fourth batch. The budget is set at US$1.77 million (PHP 90 million) each for the hulls only, but these will be armed similarly as the Mk 3 version.

In May 2018, the DND revealed that they are studying a plan to arm the Mk 1 and Mk 2 versions of the MPAC with the same Spike ER missiles that are used on the Mk 3 version. However this plan was changed by February 2020 as the Philippine Navy announced that the Mk 1 and Mk 2 versions will instead be armed only with the Mini Typhoon remote weapon station. At the 2018 Kaohsiung International Maritime and Defence exhibition, it was revealed that the 4th batch would be the same design as the prior Mk. III version of the third batch.

The bidding for these boats underwent Post-Qualification (PQ) in July 2018 while construction started in November 2018. These were then delivered in August 2019 and commissioned into service the following month in September 2019.

This fourth batch has also been designated as part of the Mk 3 version and are scheduled to be armed with Spike-ER missiles by the last quarter of 2020.
