Two 737 Boeing Business Jet (BBJ) special purpose aircraft are operated by the Royal Australian Air Force's No 34 Squadron, based at Defence Establishment Fairbairn in Canberra.
The BBJ combines the fuselage of the Boeing 737-700 aircraft with a strengthened aft section, and the centre-section, wing and landing gear of the 737-800 aircraft. Winglets are standard, affording 5 to 7 per cent reduction in cruise drag, resulting in 4 to 5 per cent increase in range. The BBJs joined the RAAF in 2002.
No. 34 Squadron operates and crews the special purpose VIP fleet of BBJs and Challengers.
