The Kingfisher class and HMS Basset provide concrete examples of prewar preparation. Both were specified soon after the 10-year rule ended, even though government limits prevented a large escort-building program. Their small hulls and weapon fits let the Royal Navy test how sloops and trawlers could perform anti-submarine and convoy duties. Basset and the Kingfishers then supplied practical design ancestry for trawlers and escorts procured during the Second World War. The ships therefore functioned as working experiments rather than isolated peacetime curiosities.
