use led the army to design a single gun mounting in two marks, both with an underground engine room to provide electrical and hydraulic power for traverse, elevation, fuze setting, ramming and other tasks. Fitted with the standard army Machine Fuze Setter No 10, these guns had a rate of fire of 10 rds/min and a maximum height of 50,000 ft, with an effective height of 36,000 ft. Mark 1A was a mild steel turret for anti-aircraft use only, Mk 1B was an armoured turret for anti aircraft and coast defence use. The gun was designated Mk 2.

By the end of 1943 only 16 of the new guns had been installed, far below projections. By the end of the war 164 guns had been produced. The high-explosive shells were fuzed with the standard army No 208 mechanical time fuze, used with 3.7 and 4.5-inch anti-aircraft guns. The guns remained in service

A 270-knot (500 km/h; 310 mph) target crossing the line of sight at right angles, at 2,000 yd (1,800 m) range, will move across the line of sight at 4.5 degrees per second. This simple fact of geometry appears to contradict the assertion that a 10-degree-per-second traverse rate

In early 1942 the Governor of Gibraltar sought 5.25-in guns for dual anti-aircraft/coast defence role. None was forthcoming. However, later that year Anti-Aircraft Command in UK acquired three twin-gun turrets from the Admiralty, which were installed around London in permanent positions. Trials and

Unlike its French and Italian contemporaries of similar size the QF 5.25-inch gun was designed as dual-purpose equipment capable of engaging both aircraft and surface targets. Combining the secondary and heavy anti-aircraft armament allowed a significant weight savings for the

Sired, Enemy Engaged, p23, states: "The Italians did not press home their attacks very hard and I thought they had a lot to put up with, as each (10 × 5.25 in gun) cruiser could fire 100 rounds of 5.25" HE shell per minute..." Ronald Sired was a gunnery petty officer on board
