Type 41 and Type 61 frigates as high-threat escorts

Were the Type 41 Leopard and Type 61 Salisbury classes intended as replacements for Second World War convoy escorts?

They were effectively more capable convoy escorts, intended for demanding and higher-threat routes rather than basic escort work.

The Type 41 and Type 61 designs were convoy escorts with extra capability for difficult environments such as Arctic routes. Their weapons suited higher-threat escort duties. Their design also led toward later Royal Navy frigate thinking. They were therefore a poor match for the least demanding trade-protection work, even though convoy escort remained part of their purpose.
