She is the sole Mulgae-class landing craft in Philippine Navy service.

The class was based on the LCU-1610 design from American shipbuilder Tacoma Boatbuilding Company.

The retired landing craft was among those committed by the South Korean Government for transfer to the Philippines in 2014, together with 16 rubber boats and 200 computers.

A tender was opened in 2018 for the repair of "LCU ROK 78",[4] but underwent several failures until a winning shipbuilder was awarded to start the works.

The newly repaired landing craft was handed-over to the Philippine Navy in 2021 and was commissioned on 6 December 2021 as the BRP Mamanwa (LC-294).
