The firm's parent company EADS now states that it must sell 420 A380s to break even, and this figure is up from a previous estimate of 270 aircraft.
So far, Airbus has sold 159 A380s and the first plane is now due in October 2007, which is two years behind schedule and the aircraft firm's biggest customer, Emirates, recently claimed it was considering its options because of the delays.
But in a presentation to analysts and investors, EADS chief financial officer Andreas Sperl pointed out that the aircraft maker were still expecting to sell more than 750 of its new planes over the life of the project.
The problems Airbus has been having with its A380 superjumbos have caused the firm to examine how it runs its businesses and earlier this month, they warned of "painful" job losses as a result of the problems with the A380.
The result of this was that France and Germany, the biggest shareholders in Airbus-owner EADS, then called for the redundancies to be fairly shared.
