Future JMSDF vessels

• The 30DX frigate is a future multi-mission frigate set to replace the Asagiri-class destroyer and Abukuma-class destroyer escort. A total of eight ships are planned to be built, with each pair to begin construction each year (starting in 2018).
• The 33DD destroyer or DDR Destroyer Revolution is a future destroyer warship in development. Procurement will begin in the FY 2021 budget and the lead ship will be launched in 2024.
• In 2014, Japanese Defense Minister Itsunori Onodera expressed the intention of buying one amphibious assault ship from the United States to provide more amphibious capabilities than the current Osumi class landing ships. The Wasp-class amphibious assault ship is most likely candidate for acquisition.
