Airbus manufactured the A340 in four fuselage lengths.
The initial variant, A340-300, which entered service in 1993, measured 59.39 metres (194.8 ft). The shorter −200 was developed next, and the A340-600 was a 15.91 meters (52.2 ft) stretch of the −200. The -600 was developed alongside the shorter A340-500, which would become the longest-ranged commercial airliner until the arrival of the Boeing 777-200LR. The two initial models were powered by the CFM56-5C, rated at 151 kilo newtons (34,000 lbf), while Rolls-Royce held exclusive power plant rights to the extended-ranged and heavier −500 and −600 models, through the 267 kilo newton (60,000 lbf) Rolls-Royce Trent 500. Initial A340 versions share the fuselage and wing of the A330 while the −500/-600 models are longer and have larger wings.

Launch customers Lufthansa and Air France placed the A340 into service in March 1993. As of September 2011, 379 orders had been placed (not including private operators), of which 375 were delivered. The most common type were the A340-300 model, with 218 aircraft delivered. Lufthansa is the biggest operator of the A340, having acquired 59 aircraft. The A340 is used on long-haul, trans-oceanic routes due to its immunity from ETOPS; however, with reliability in engines improving, airlines are progressively phasing out the type in favour of more economical twin jets such as the Boeing 777. Airbus announced on 10 November 2011 that the A340 programme had been terminated due to lack of new orders.
