Would an early US Navy 3-inch/50 be a suitable replacement for the Flower class's 4-inch gun?
Short answerIt would fit the role, but production priorities would probably send new 3-inch guns to destroyers while Flowers retained stored 4-inch guns.
NotesThe 3-inch/50 was technically suitable for a Flower-class corvette, although suitability did not guarantee allocation. The emergency escorts were designed to use equipment already available in stores and to be completed cheaply and quickly. Newly manufactured dual-purpose guns would be more valuable on destroyers and other modern ships designed to exploit them.
