No. 13 Squadron RAAF

No. 13 (City of Darwin) Squadron is a Royal Australian Air Force (RAAF) squadron. The squadron saw combat during World War II as a bomber and maritime patrol squadron and is currently active as a mixed regular and reserve RAAF unit located in Darwin, fulfilling both operational support and training duties.

History
No. 13 Squadron was formed from elements of No. 12 Squadron at RAAF Base Darwin on 1 June 1940. Its first commanding officer was Wing Commander John Balmer. The squadron initially operated Avro Ansons, serving in the general reconnaissance role and flew maritime surveillance patrols over the seas to the north of Australia and survey flights over northern Australia. The squadron was re-equipped with Lockheed Hudson light bombers, suffering its first loss in September when one aircraft was destroyed on take-off. In early 1941, the squadron was tasked with locating a German commerce raider and a U-boat, before joining the search for survivors from HMAS Sydney following its battle with the German auxiliary cruiser Kormoran. In May 1941, the squadron began flying familiarisation flights over the Netherlands East Indies in preparation to deploy to the NEI following the outbreak of war with Japan.

On 7 December, following the start of the Pacific War, No. 13 Squadron deployed two flights of Hudson light bombers to Ambon, where they were based at Laha Airfield. Three days later, the squadron's commander, Wing Commander Joshua McDonald, was killed in an accident; Squadron Leader John Ryland took over and shortly afterwards the squadron deployed a third flight to Namlea Airfield on Buru Island. At the end of the month, the third flight moved to Babo in Dutch New Guinea. Flying in the face of heavy resistance, and lacking fighter support, the squadron's aircraft conducted operations throughout the eastern islands of the NEI, during which several aircraft were lost. Others were also destroyed on the ground as Japanese aircraft attacked Laha. The surviving aircraft from these flights returned to Darwin in February 1942, as Ambon faced invasion.

No. 13 Squadron was severely affected by the Japanese air raids on Darwin on 19 February 1942, with the squadron's headquarters, stores and spares being destroyed. Its aircraft were undamaged, having been moved inland to Daly Waters the previous week, or over Timor on task. In March, No. 13 Squadron moved to Hughes airfield. As a result of the squadron's heavy losses during the defence of the NEI and the raids on Darwin, No. 13 Squadron generally only had one or two aircraft operational on most days in early 1942. Nevertheless, the squadron continued to fly operational attack and reconnaissance missions over the NEI, including an anti-shipping raid around Beco, in Timor, on 10 August 1942, which sunk one Japanese transport and damaged another in a mast-height attack that was launched in response from intelligence information provided by Australian commandos deployed on the island as part of Sparrow Force. No. 13 Squadron was later awarded the United States Presidential Unit Citation for its operations over Timor during August and September 1942. No. 13 is one of only two RAAF squadrons to have received this honour; the other unit was No. 2 Squadron which received the award for its performance in the Vietnam War.

The squadron continued to conduct operations against the Japanese until 4 April 1943 when it handed its Hudson aircraft over to No. 2 Squadron and was withdrawn to RAAF Base Fairbairn to rest and re-equip. At Fairbairn the Squadron took delivery of Bristol Beaufort and Lockheed Ventura aircraft and conducted anti-submarine and shipping patrols along the Australian east coast. The Beauforts were handed over to No. 2 Squadron in August. The future Australian Prime Minister Gough Whitlam joined the squadron as a navigator during 1943.

No. 13 Squadron moved to Cooktown in late May 1944 before moving again to Gove in August from where it mainly carried out anti-submarine and escort patrols, though it also mounted a small number of bombing raids against the eastern islands of the NEI. In late June 1945 the squadron moved to Morotai in the NEI and, soon after the end of the war, to Labuan in British North Borneo. From Labuan the squadron operated in the transport role and ferried ex-prisoners of war and other personnel back to Australia before being disbanded on 11 January 1946. Casualties during the war amounted to 87 personnel killed.

No. 13 Squadron was re-formed as a non-flying Active Reserve squadron located at RAAF Base Darwin on 1 July 1989; later that month it was conferred with the title "No. 13 (City of Darwin) Squadron". On 31 May 1990 the squadron was officially presented the Presidential Unit Citation it had been awarded in 1942. On 1 July 2010 changes to the structure of the Combat Support Group resulted in the combat support and fixed base services functions of No. 321 Expeditionary Combat Support Squadron (321 ECSS) being integrated with No. 13 Squadron at RAAF Darwin and 321 ECSS being disbanded.
