Under this definition, the light frigate is the smallest combatant intended to operate within a wartime task group. Its role depends on support from other forces and excludes isolated picket duty or an independent battle. One employment is in home waters alongside land-based operations; another is within a group whose larger ships supply capabilities the frigate lacks. Mogami adds the hull numbers needed to fill out that group. Asagiri and Abukuma provide the older escort roles used to explain its replacement mission, which leaves the principal combatant's duties to larger ships.
