Malta-based submarines could evade daytime air attack by submerging, but Force K's surface ships had to remain exposed. The Arethusa class offset some of that risk through strong subdivision, useful anti-aircraft armament, and a destroyer-like silhouette that could complicate identification. During George VI's visit to Malta, an Arethusa-class cruiser carried him while four destroyers had orders to ensure the cruiser reached safety whatever happened. The arrangement shows how much confidence the Royal Navy placed in the type's survivability. Economical high-speed performance also suited the fast sorties required from Malta.

Why Arethusa cruisers suited exposed Malta operations
Unlike submarines, Force K's surface ships could not hide from daylight air attack, making the Arethusas' anti-aircraft armament, resilience, and economical speed especially valuable.
