relocating to Amberley. Also on 17 November, Wing Commander Linda Corbould took command of the unit, becoming the first woman to lead an RAAF flying squadron. Corbould was responsible for delivering the first Globemaster from the United States to Australia on 4 December. No. 36 Squadron achieved initial operating capability with the C-17 on 11 September 2007, following eight months' work-up training. In June 2008, it received the Gloucester Cup as the RAAF's most proficient flying squadron of 2007 "for achieving all training objectives, supporting air lift activities globally and nationally and fulfilling short-notice, high priority tasks, despite the squadron's expertise being in its infancy". Corbould completed her posting as commanding officer on 8 December 2008, the day the squadron marked the second anniversary of C-17 operations by conducting the RAAF's first flight with an all-female aircrew. Since re-equipping with the Globemaster, No. 36 Squadron has continued to support Coalition forces in Afghanistan, as well as humanitarian operations worldwide. In 2011, it took part in relief efforts following the floods in Queensland, the Christchurch earthquake, and the Tōhoku earthquake and tsunami in Japan. The Queensland floods necessitated the evacuation of two C-17s to Richmond, when Amberley was threatened by rising waters; of the other two Globemasters, one was in the Middle East and the other was undergoing maintenance at Amberley and could not be flown but was moved onto high ground and escaped damage. The deployment to Japan involved all three of the squadron's available C-17s, the fourth still being serviced at Amberley. On 11 May 2012, a C-17 flew an Australian Army M1 Abrams tank from RAAF Base Darwin to Shoalwater Bay for a training exercise; it was the first time an RAAF Globemaster had airlifted an Abrams, which at 61 tonnes was among the largest single items the 70-tonne-capacity aircraft could carry. In November that year the squadron took delivery of its sixth Globemaster. It was again awarded the Gloucester Cup in March 2013, for its proficiency the previous year. In September 2014, RAAF C-17s were used to airlift arms and munitions to forces in Kurdish-controlled northern Iraq following an offensive by ISIL militants. On 10 April 2015, Prime Minister Tony Abbott announced the purchase of two more C-17s, which would bring No. 36 Squadron's complement to eight aircraft. Concurrent with delivery of the new C-17s by year's end, No. 36 Squadron's facilities were to be improved, obviating
