The Australian version of the English Electric Canberra bomber—designatedB.20 and based on the British-built B.2—now equips two R.A.A.F. bomber squadrons. Production of the aircraft is undertaken for the Defence Department's Division of Aircraft Production inGovernment aircraft factories, although there is a considerable amount of sub-contracting to private industry—notably for the production of pressings and wing spars. The AustralianCanberra has Commonwealth-built Avons and Australian radio, instrumentation and other operational equipment installed. The first of an initial order for 48 aircraft flew in May 1953, but additional contracts for laterversions of the Canberra (for which designations Mk 21-24 inclusive have been reserved) will keep the type in production until 1957. Output is at present geared to the R.A.A.F.'s peace-time requirement for approximately 20 Canberras a year. de Havilland Vampire. Early next year the Vampire T.33 trainer will be adopted by theR.A.A.F. as its standard advanced trainer. Unlike the single-seat Australian Vampires, the Trainers are powered by imported Goblins, as employed in all British-built versions. Produc-tion of the T.33 (the Australian designation of the Vampire T.ll) is likely to continue for the next two or three years—about 100 will ultimately be built. D.A.P. Jindivik. Designed to a Ministry of Supply specification, the Jindivik I pilotless jettarget aircraft made its first flight in August 1952, powered by an Armstrong Siddeley Adder turbojet. A later design powered with a 1640 lb s.t. Viper engine and designated Mk 2,underwent its first trials in December 1953. Aerodynamically based upon the Mk 1, the Jindivik 2 has a larger intake to accommodate the increased mass flow, and changes have beenmade to the wing thickness and to the rear fuselage lines. Constructed from the lower alloy grades of aluminium, the Jindivik is engineered to avoid the use of forgings, extrusions andmachined fittings. The fuselage is built in four main sections—front fuselage, equipment bay canopy, centre fuselage and rear fuselage. Centre G.A. drawing, Vampire. Below, Jindivik.
