HMCS Haida's twin four-inch mountings reflected two wartime pressures. The fleet needed more high-angle anti-aircraft fire across its ships. Builders also had to use weapons available soon enough to get new hulls into service rather than wait indefinitely for the ideal fit. The mountings belonged to the period before 40 mm Bofors weapons became widely available. Immediate fleet need and production flow could shape a warship's realized armament.
