MONTREAL--Bombardier Aerospace says it has received two orders worth about US$800 million for 13 Global business jets from two undisclosed customers.

One firm order is for four Global 6000 and four long-range Global 8000 aircraft, valued at US$500 million based on 2012 list prices. The second is for four Global 6000 and one Global 8000 aircraft.

Bombardier (TSX:BBD.B) business aircraft president Steve Ridolfi said sales momentum for its new Global 8000 aircraft is strong while the entire line of large jets offers great range, cabin volume and a vision flight deck.

The backlog for its Global line of planes is 35 months.

The Global 8000 is slated to enter into service in 2017. Bombardier said the delivery schedule for the 13 aircraft is confidential.

The new Global 7000 and 8000 planes under development are forecasted to generate US$1.5 billion to US$2 billion in annual revenues.
