It was decided to increase Ariane's performance margin by 100 kg over the guaranteed figure (1500 kg). The nozzles of the first-stage Viking engines were modified and, by reducing the ullage spaces, the masses of propellants carried in the first and second stages were increased by 5 t and 1 t, respectively. When the results of the engine tests were known and the stages were weighed, it proved possible to increase the guaranteed performance to 1700 kg, the difference between this and the calculated performance still being 100 kg.
