The conversion fits Reginald Henderson and Stanley Goodall's vision for a Royal Navy able to protect global trade and maintain a worldwide presence. The ships would fill the gap between a destroyer and a cruiser for escort work, armed-merchant-cruiser support, and secondary presence missions. They would likely receive ASDIC or hydrophones plus limited anti-submarine gear. Their purpose would be to support destroyers and sloops rather than lead independent submarine hunts.
