Where the Grimsby class fitted into interwar escort thinking

Where did the Grimsby class fit into Royal Navy sloop and anti-submarine thinking?

It was a long-range Indian Ocean and Far Eastern ASW sloop designed for heavy depth-charge work and construction in Australian, and potentially Indian, yards.

The Black Swan, Egret, Hunt, corvette, and frigate line grew from interwar sloop experimentation. The Grimsby class was a long-range ASW design for the Indian Ocean and Far East, carrying heavy depth-charge stowage as well as useful guns. It was deliberately suitable for construction at Cockatoo Island in Australia, with hopes that Indian yards might follow. Beginning with sloops gave overseas yards experience building to warship rather than merchant standards. Dispersed construction and repair capacity would reduce dependence on British yards vulnerable to bombing.
