The three-inch AA guns were modified accordingly. 613: 803:, the 3.7 was considered for use explicitly as an anti-tank weapon due to the shortage of suitable anti-tank guns. Sighting arrangements were improved for the anti-tank role, but the weapon was far from ideal. Its size and weight - two tons heavier than the German Flak 8.8 cm - made it tactically unsuitable for use in forward areas. The mounting and recuperating gear were also not designed to handle the strain of prolonged firing at low elevations. 1113: 879: 1056: 949: 1147: 1073: 848: 989: 1002: 963: 1042: 1015: 444:
anti-aircraft units were to engage targets up to 24,000 feet (7,300 m). Mechanical, as opposed to igniferous, time fuses were required because the speed of powder burning varied with height so fuse length was not a simple function of time of flight. Automated fire ensured a constant rate of fire that made it easier to predict where each shell should be individually aimed.

in the later stages of the war, under-employed 3.7 units were called upon to supplement the field artillery in both the North West Europe and Italian theatres, where the accuracy and effectiveness of the 3.7 with mechanical Fuse 207 at ranges up to 20,000 yards (18,000 m) and all-round traverse

of a new design shell giving reduced air resistance and hence better ballistic performance, and causing far less barrel wear. The maximum ceiling for the gun was about 15,240 m (50,000 ft). It was mounted on the Mounting Mk IIA and therefore deployed in static emplacements only. In service

Like the Mk IV this was based on the 4.5 inch barrel design lined down to 3.7 inches, and using the 4.5 inch size cartridge. However, Colonel Probert changed the barrel to have gradual rifling: the rifling groove depth decreased to zero over the last five calibres of the barrel before

produced a mock-up and proceeded to develop prototypes of the weapon, which was selected over a competitor by the state Design Department and passed acceptance tests in 1936. The weight specification was exceeded, the muzzle velocity not achieved and the mechanical time fuse, No. 206, was still some

Two assumptions underpinned the British approach to HAA fire. First, aimed fire was the primary method and this was enabled by predicting gun data from visually tracking the target with continuous height and range input. Second, that the target would maintain a steady course, speed and height. Heavy

However, the war had shown the possibilities and potential for air attack and lessons had been learned. The British had used AA guns in most theatres in daylight, as well as against night attacks at home. They had also formed an AA Experimental Section during the war and accumulated much data that

The gun's effective ceiling varied depending on the predictor and fuse. The Mk VI ordnance significantly increased the potential effective ceiling. The British definition of effective ceiling at the start of World War II was "that height at which a directly approaching target at 400 mph can be

Initially, there were HE and shrapnel shells, both fitted with a time fuse. Fuse No.199 was igniferous (i.e. powder-burning) with a maximum running time of 30 seconds. Fuses No. 106 and 107 were mechanical time fuses; both proved unsatisfactory. Fuse No. 208, with a maximum running time of 43

The other used a travelling platform (Mounting Mk II) with detachable wheels for guns to be used in static positions but which could be re-positioned. The mounting had a pedestal that was fixed to a solidly constructed, preferably concrete, platform on the ground. In 1944, it was found that a

In 1928, the general characteristics for a new HAA gun were agreed, a bore of 3.7 inches (94 mm) firing 25 lb (11 kg) shells with a ceiling of 28,000 feet (8,500 m). Financial stringency led to no action being taken until the 1930s, when the specification was enhanced to a

Being a high-velocity gun, with a single charge and firing substantial quantities of ammunition, meant that barrel life could be short and by the end of 1940 there was a barrel shortage. Some of the substantial numbers of spare barrels required were produced in Canada.

The gun was produced in two versions, one mobile and another fixed. The fixed mounting allowed more powerful ammunition, Mk. VI, which gave vastly increased performance. Six variants of the two designs were introduced. The gun was also used as the basis for the

as the most commonly used type. Shortly before the end of the war, a new QF 3.6 inch gun was accepted for service but the end of the war meant it did not enter production. After the war, all anti-aircraft guns except the three-inch gun were scrapped.

As of 1949, erosive cordite propellant was not used with Mk 6 guns, but instead 17 lb and 2-6 oz of different single-base nitrocellulose propellant (as opposed to slightly over 7 lb 1 oz of cordite or around 8.5-9 lbs of single-base for Marks 1-3 guns).
