A Commonwealth cruiser for the GIUK gap

What might a joint British, Australian, and Canadian cruiser for the GIUK gap look like?

Probably an evolved Type 82 with a stern helicopter deck and facilities for several helicopters, though its classification would vary by navy.

The answer treats the ship as an enlarged, updated Type 82 rather than an entirely new concept. A stern aviation arrangement supporting roughly three helicopters would strengthen anti-submarine work in the GIUK gap. British, Canadian, and Australian participation would give the design a shared Commonwealth basis. Whether it was called a cruiser or destroyer would depend as much on national classification habits as on the design itself.
