In April 1956, the first production Alouette II was completed, making it the first production turbine-powered helicopter in the world. Upon completion, several of the initial production models were dispatched for a series of evaluation flights in the Alps. On 13 June 1958, a single SE 3130, again flown by Boulet, re-took the altitude record, reaching a height of 10,984 m (36,027 ft). In 1975, production of the Alouette II ended after more than 1,300 had been built; in 1969, a new high-altitude variant, the Aérospatiale SA 315B Lama had been developed to replace it in this niche capacity. A slightly larger and more powerful helicopter in the form of the Aérospatiale Alouette III has also entered production, which had negatively impacted upon the demand for the older II model.
