Question

Which would be better for Atlantic escort work, a Flower-class corvette or a Tacoma-class frigate?

Short answer

Tacoma was the better mature escort, but Flowers were the realistic 1939 design that could be built quickly with the yards and technology already available.

Notes

A Tacoma-class frigate offers more speed, endurance, seakeeping, and room for sensors and weapons than a Flower. That comparison ignores when each design and its supporting technology became available. Britain needed escorts immediately in 1939 and could distribute the Flower's commercial machinery and hull standard across many yards. Tacoma is preferable once it exists, while the later superior ship cannot replace the emergency vessel that kept convoys moving earlier.
