In 2016, the
Armed Forces of the Philippines Northern Luzon Command pushed for the establishment of a Marine detachment on Mavulis Island to affirm Philippines'
sovereignty over the northernmost point of the archipelago. The Marine detachment was opened in 2018, with a fisherman's shelter completed in 2019 and turned over to the local municipality for maintenance and operation. In May 2021, the
Department of Defense of the Philippines announced the electrification of the island through a solar power station, with a back-up diesel generator. This was done through the help of the One
Meralco Foundation. The DND also announced the commissioning of a
desalination plant to provide potable water to personnel assigned to the island. In October 2023, the
Armed Forces of the Philippines inaugurated a new
naval detachment as headquarters for military troops on the Island. "This island underscores the strategic importance of this detachment. It serves as our watchful sentinel in the northernmost beaches of our maritime borders, ensuring the security and sovereignty of our homeland," Fernyl G. Buca,
AFP Northern Luzon Command said. In 2024, there had been plans of upgrading several civilian ports in the Batanes Island chain, including Mavulis Island, to accommodate the unloading of more cargo from Manila and as preparation for possible contingencies that may arise should Filipino workers in Taiwan would repatriate in the event of a
China-Taiwan conflict. Mavulis Island itself has been one of many frequent locations for the joint US-Philippines military training exercises called
Balikatan held annually. ==Gallery==
