 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.
