Judge a sloop by its mission, not first-rate status

Warships did not all need to be optimized for the maximum imaginable threat. The relevant design question was the mission profile: whether a ship had to lead a battle, screen a fleet, secure a task group, or maintain routine presence. Acacia-class armament centered on 12-pounders and 3-pounders, while later batches often carried 4-inch or 4.7-inch guns and the anti-submarine designs added depth-charge throwers. The exact fit varied, but it was adequate for mines, submarines, escort support, and many lower-threat duties. These sloops supported stronger units without consuming the money, crew, and machinery required by a first-rate combatant.
