 More modern fire control equipment was fitted and the Oerlikon guns were replaced by single Bofors 40 mm anti-aircraft guns, with a twin Bofors 40 mm mount replacing the quadruple pom-pom.Between 1957 and 1959, the ship was refitted as a Type 16 frigate, which resulted in a completely revised armament being fitted.A twin 4 inch gun was mounted forward with a close-in anti-aircraft armament of five Bofors 40 mm guns (one twin and three singles).
