Akatsuki (PLH-34) is a Reimei-class patrol vessel currently operated by the Japanese Coast Guard.

Design[edit]

Reimei-class carries two 40 mm autocanon and two JM61 20 mm machine guns, as does the Akitsushima.^[2] Gun mounts of 40 mm autocanons are changed to Mk4, which is lighter than the Mk3 mounted on the Akitsushima.^[2] Both are capable of being remotely controlled with optical directors.^[3]

Aviation facilities are also similar to that of Akitsushima, capable of carrying two EC225LP Super Puma helicopters: however, only one helicopter is normally carried on this vessel.^[2]

Construction and career[edit]

Akatsuki was laid down on 16 February 2018 and launched on 10 April 2020 by Mitsubishi, Nagasaki. She was commissioned on 16 February 2021.^[4][5]
