Dassault delivered 55 Falcon jets last year, the company said on Tuesday, down from 66 in 2014. New orders halved to 45 planes and a further 20 were cancelled by NetJets, the leasing firm owned by Berkshire Hathaway.

"The economic environment especially in emerging countries strongly impacted our prospects and customers," Dassault said in a statement.

Deliveries of Dassault's Rafale fighter jet also fell to eight planes in 2015 - five to France and three to Egypt - from the 11 French deliveries recorded in 2014. But the company took 48 new Rafale orders in the course of the year, 24 each from Egypt and Qatar.
