No. 9 Operational Group was a major Royal Australian Air Force (RAAF) formation providing fighter, ground-attack and anti-shipping support to the Allies in the South West Pacific theatre during World War II. Established in September 1942, it acted as a mobile striking force independent of the RAAF's static area commands. As the war in the Pacific progressed, No. 9 Operational Group itself developed into an area command called Northern Command, covering New Guinea.

No. 9 Operational Group (No. 9 OG) was formed in New Guinea in September 1942, consisting of seven RAAF squadrons attached to the USAAF's Fifth Air Force.[1][2] Four of the squadrons were based at Milne Bay and three at Port Moresby.[3] On its establishment it was the RAAF’s "premier fighting unit" in the South West Pacific Area (SWPA).[4] Its first commander was Group Captain Bill Garing.[5]

Administratively, No. 9 OG initially came under the control of RAAF No. 71 Wing, covering the units in Milne Bay, and No. 73 Wing, those in Port Moresby.[3]

In March the group provided the RAAF's contribution to the Battle of the Bismarck Sea, "the decisive aerial engagement" in the SWPA according to General Douglas MacArthur, resulting in twelve Japanese ships being sunk.[5] Between July and October 1943, No. 9 OG was expanded to include a works wing and a radio location wing, its complement of operational squadrons totalling nine, plus a torpedo bomber detachment. Its aircraft carried out operations against enemy bases, shipping and lines of communication along the coast of New Britain.[3][6] In October–November the group launched a number of major assaults on Rabaul, bombing and strafing ground and naval targets.[7]

Although Hewitt was performing an "excellent job" according to Fifth Air Force commander Major General Frank Lukis, who had commanded North-Eastern Area in 1942.[4][8]

In December 1943, No. 9 OG's Kittyhawks took part in a series of attacks culminating in the Battle of Arawe.[9] As the Pacific conflict gradually shifted further north, however, operational tasking lessened and No. 9 OG became colloquially known in the RAAF as the "Non-Ops Group".[10] It assumed the duties of a garrison force in New Guinea and was renamed Northern Command on 11 April 1944, to better reflect its new function. Its mobile strike role was taken over by No. 10 Operational Group (later renamed the Australian First Tactical Air Force), which had been formed on 13 November 1943.[2][11]

Order of battle

Upon its establishment in September 1942, No. 9 OG consisted of the following units:

In February 1943 the squadrons at Milne Bay became part of No. 71 Wing, while those at Port Moresby formed No. 73 Wing, both wing headquarters reporting to No. 9 OG.[3]
