The Ariake-class, JDS Yūgure (DD-184), 1960 (ゆうぐれ, namesake: Twilight), formerly USS Richard P. Leary (DD-664), was a Fletcher-class destroyer of the US Navy. She was loaned to Japan in 1959 along with a sister ship (JDS Ariake (DD-183), formerly USS Heywood L. Edwards (DD-663)), and underwent modifications to serve as a training and experimental vessel. The Yūgure participated in mine warfare until 1974, when she was decommissioned and returned to the US Navy. She was scrapped in 1976 together with her sister.

She was introduced during Update "Ixwa Strike" as a reward for the Future Technology event. Yūgure is a stripped-down Fletcher (DD-445) that sacrifices one 5-inch gun, torpedoes, and 20 mm cannons for additional 40 mm twin mounts. This gives her a reduced battle rating and allows her to face less powerful opponents more often. The remaining 5-inch guns have a high fire rate and damage output that can destroy older destroyers easily, and the 40 mm cannons can deal with small patrol boats effectively.
