Yubetsu (DE-228)

The West Japanese destroyer escort RJS Yubetsu (DE-228) in port on July 30th, 2004.

The Yubari-class destroyer escort of the Republic of Japan Navy (RoJN) is the successor of the Ishikari-class destroyer escort. Yubari was named after the experimental light cruiser of the 1920s-30s, which served in (and was lost during) World War II.

This class was the extended version of its predecessor, RJS Ishikari (DE-226). The displacement was slightly increased, and some improvements were introduced.

All two ships of this class were deployed at the Kagoshima District Force. Originally it was planned to build six of this class (1985 Mid-Term Defense Buildup Program). However it was decided that even this class was too small to continue in production, so it was succeeded by the Abukuma-class with an entirely new design.
