Force K's planned interception combined radio information with Ark Royal's aircraft and Renown's speed and guns. A surface raider returning from the South Atlantic to the North Atlantic would face both air attack and surface interception. With luck, radio signals would indicate where to look. Once the raider was found, Swordfish would attack, probably slowing it and possibly sinking it. Renown was expected to finish off a ship that survived the air attack.

How Force K planned to intercept a returning raider
Radio signals could guide Force K's search for a raider returning north, with Swordfish attacks intended to slow or sink it before Renown closed in.
