 To prepare aircrew for their rotation through No. 2 Squadron in Vietnam , No. 1 OCU students participated in exercises such as Combat Skyspot in August 1968 , which utilised radar controlled by No. 30 Squadron , and Strait Kris in September – October 1969 , in conjunction with the Australian Army . The unit lost two more aircrew when a Canberra M.21 on a training flight crashed near Amberley on 23 March 1970 . From 21 March to 25 April 1971 , four of the unit 's aircraft flew 10 @,@ 000 miles around Australia to conduct seven flying displays as part of the RAAF 's Golden Jubilee celebrations . Having completed thirty @-@ six conversion courses in its twelve years of operation , No. 1 OCU was disbanded on 9 June 1971 , following the withdrawal of No. 2 Squadron from Vietnam . Unit staff were transferred to No. 2 Squadron , which continued to operate the Canberra and carry out its own operational conversion until disbanding in June 1982 . Ten of No. 1 OCU 's fifteen Canberras were put into storage and the remainder , including surviving Mk.21 trainers , were taken on by No. 2 Squadron . When the F @-@ 111C eventually entered service with No. 82 Wing in 1973 , No. 6 Squadron again took responsibility for conversion training , while No. 1 Squadron acted as the lead strike unit .
