1942 The squadron became operational in April 1942, by this time having 68 New Zealand flying personnel. The squadron moved to
Thorney Island in the south of England from where it carried out anti-submarine patrols into the Atlantic and as far as the
Bay of Biscay. Shortly after it began these flights, one of its aircraft were attacked by
Focke-Wulf Fw 190 fighters, the first engagement with the
Luftwaffe for the squadron. The Hampden that was attacked was able to safely return but with two of its crew wounded. Its rear gunner was awarded the squadron's first
Distinguished Flying Cross for having likely shot down one of the Fw 190s. In July, No. 489 Squadron returned to Scotland, based at
RAF Skitten, where its primary task was patrolling the Norwegian coast and attacking shipping. It also provided aerial cover for vessels making their way to the naval base at
Scapa Flow, escorted convoys to the Russian Arctic and also carried out anti-submarine patrols. On 17 September, the
Karpfanger, a ship of 5,000 tons, was torpedoed by
Flying Officer A. J. Mottram, the first ship to be sunk by the squadron.
1943 At the start of 1943, the squadron moved to the
RAF station at
Wick, located on the north-east coast of Scotland. By this time, it was being led by Wing Commander V. Darling. It continued with its anti-shipping work along the Norwegian coast, making 18 attacks on vessels by the middle of the year. One notable success, which occurred while working with the Australian
No. 455 Squadron, was the sinking of the
Ahrensburg near
Stavanger in late January. A 7,000-ton merchant ship was sunk in early April and at the end of the month, another was so badly damaged it was run aground. Its anti-shipping work was dangerous; heavy flak fire often damaged, if not destroyed, the attacking aircraft and German fighters were easily a match for the obsolete Hampdens. Over the summer months there was increased emphasis on anti-submarine patrols and search and rescue missions. In August, Wing Commander John Dinsdale, a New Zealander, took over command of the squadron. On 16 September it flew its last major operation with the Hampdens when a flight of four aircraft attacked a five-vessel convoy it sighted while patrolling along the Norwegian coast. They were able to sink a merchant ship. Soon afterwards, it was taken off operations having accounted for sinking 36,000 tons of shipping by this stage of the year. The squadron returned to Leuchars to begin converting to the
Bristol Beaufighter, a process which took several weeks. As the Beaufighter only required two aircrew, a pilot and navigator, the wireless operators and air gunners were surplus to requirements. In addition, several of its navigators were posted to other units while the pilots learnt to operate the Beaufighter.
1944 The squadron returned to operations in January 1944 and returned to its anti-shipping duties, targeting merchant vessels, loaded with supplies for the German war effort and often accompanied by
flak ships, steaming along the Norwegian coast. On the squadron's first sortie with the Beaufighter, it attacked a convoy of ships near the southern coast of Norway. A merchantman of around 12,000 tons was sunk before a group of
Messerschmitt Bf 109 fighters saw off the attackers. Another ship, spotted earlier in the sortie, was strafed and badly damaged. From March 1944 No. 489 Squadron formed part of the
Anzac Strike Wing, along with No. 455 Squadron, and shortly afterwards moved south to a base at
Langham, in
Norfolk. The wing operated in support of the Allied preparations for the upcoming
invasion of Normandy. It often flew operations to France and the
Low Countries, targeting merchant ships and looking for movement along shipping lanes. During these operations, a portion of the attacking Beaufighters were equipped with cannon instead of torpedoes, their role being to target the anti-aircraft defences of the shipping being attacked. They also sought out
E-boats and
R-boats, which were German
armed motor launches. On
D-Day itself and immediately afterwards, the Anzac Strike Wing was tasked with seeking out and destroying E- and R-boats, which could threaten the vessels of the Allied invasion fleet. Flying as far as Holland through to
Dieppe, around 34 motor launches were attacked by the squadron and many of these were sunk. A major sortie was conducted on 15 June, when the squadron fulfilled an anti-flak role while several other squadrons attacked a E-boat depot ship and a 8,000-ton supply ship with torpedoes. This saw both ships sunk and as many as ten escort vessels destroyed with no losses among the attacking aircraft. Two weeks later saw more major success for the squadron, with two cargo ships destroyed off the
Frisian Islands. The threat posed by German surface vessels in the
English Channel had considerably reduced and No. 489 Squadron was soon able to return to its previous anti-shipping role along the Norwegian coast. By October, No. 489 Squadron, now led by Wing Commander L. A. Robertson, was operating from
RAF Dallachy in Scotland. It was uncomfortable for the personnel of the squadron due to the inclement weather in the area and the relatively crude facilities. The aircraft flew day and night, and when they reached the Norwegian coast, often had to fly deep into the
fjords to seek out German shipping. The high losses experienced by the Germans resulted in more shipping moving at night and sheltering in the fjords during the day.
1945 and disbandment No. 489 Squadron's anti-shipping work along Norway's coast continued into 1945, and for the final months of the war it was led by Wing Commander D. Hammond. The squadron continued to operate as part of the Anzac Strike Wing, which now included a British squadron as well as the Australian unit. Major sorties during the year included one on 9 February to
Førde Fjord, in which a
Narvik-class destroyer was attacked and damaged by 30 Beaufighters. Later in the month, one of the squadron's crews sighted and sunk the
Alsterstum, a 2,500-ton freighter carrying a load of mines. Another crew torpedoed a 3,000-ton cargo ship the following month. The last operational mission for the squadron, involving a pair of Beaufighters, was flown on 21 May. By this time, it had carried out about 1,250 sorties in the previous five months. In June, with the war in Europe now at an end, it moved to
RAF Banff, in
Banffshire, and began to re-equip with the
de Havilland Mosquito with a view to moving to the Pacific. However, before the conversion to Mosquitoes was completed, the
Empire of Japan collapsed and the war ended. The squadron was subsequently disbanded on 1 August.
Operational summary During the course of its service during the Second World War, No. 489 Squadron flew 2,380 sorties and 9,773 hours on operations. A total of 33 New Zealanders were killed while serving with the squadron. Awards made to its personnel as a result of their service with the squadron included two
Distinguished Service Orders, 19
Distinguished Flying Crosses with one
bar, a
Conspicuous Gallantry Medal and a
Distinguished Flying Medal. ==Commanding officers==
