On 10 September 1944, No. 1 PRU was re-designated as "No. 87 Squadron" at Coomalie Creek Airfield in the Northern Territory. The new squadron was initially equipped with two Wirraways and a Mosquito and was tasked with providing photo reconnaissance support for Allied operations in South East Asia and the Netherlands East Indies. Operating from Coomalie Creek the squadron primarily conducted reconnaissance flights over the eastern islands of the Netherlands East Indies, with occasional missions over Java and other parts of South East Asia. As more Mosquitoes were received the number of missions flown increased. A detachment from the squadron was briefly based on the Cocos Islands in June 1945 where it unsuccessfully attempted to photograph targets in Singapore, being hampered by bad weather and the loss of an aircraft.
