Hi
A recent work done.
Australian Canberra used in Viet Nam war
"...A84-247 was allotted to 2 Squadron RAAF for service in Vietnam in July 1967, and flew its first operational sortie on 14 July. It continued in operational use until 11 June 1968 when it returned to Australia for servicing followed by a brief posting to 1 Operational Conversion Unit (OCU) at Amberley Queensland. In July 1969 the aircraft returned to 2 Squadron and carried out its next operational flight on 19 July 1969. It remained with the Squadron until February 1971, undertaking its last bombing operation on 6 February 1971. This aircraft was used for both medium and low level bombing operations, and is known to have completed at least 680 operational flights in Vietnam. ..."
