How Flowers gained weapons, sensors, and endurance during the war

Flower-class equipment expanded as the Battle of the Atlantic demanded more from each escort. The ships carried radar and ASDIC, while depth-charge capacity and handling arrangements grew beyond the original fit. Official load figures were only a baseline because crews used spare deck space for additional charges and acquired extra light anti-aircraft weapons whenever captains and admirals were willing to overlook the changes. Chiefs also adjusted machinery they knew intimately, extracting more from a commercial-standard plant. This adaptability increased the Flowers' usefulness, though their weaker subdivision and tighter weapon capacity still imposed a human cost compared with Black Swan-class sloops.
