From Wikipedia: "High Angle Control System (HACS) was a British anti-aircraft fire-control system employed by the Royal Navy from 1931 onwards and used widely during World War II. HACS calculated the necessary deflection required to place an explosive shell in the location of a target flying at a known height, bearing and speed.
"Demonstrating the RN's rapid strides in naval AA gunnery, in May 1941, HMS Prince of Wales went to sea with HACS IVGB, with full radar ranging systems, and no less than 9 AA associated fire control radars: four Radar Type 285, one on each High Angle Director Tower (HADT) and four Radar Type 282, one on each Mk IV QF 2 pdr "pom pom" director, and a long range Radar Type 281 Warning Air (WA) radar which also had precision ranging panels for aerial and surface targets. This placed HMS Prince of Wales in the forefront of naval HA AA fire control systems at that time. In August and September 1941, HMS Prince of Wales demonstrated excellent long range radar directed AA fire during Operation Halberd. However, although the shortcomings of HACS are often blamed for the loss of Force Z, the failure of the anti-aircraft gunnery on intercepting the Japanese bombers were due to bizarre circumstances. The HACS was originally designed on Atlantic conditions on mind, not the tropics, and by December 1941, Prince of Wales's AA FC radars had become unserviceable due to the extreme heat and humidity in Malayan waters and her 2 pdr ammunition had deteriorated badly as well."
