Sukhoi said Tuesday that it would sell 12 of its Superjets to privately owned Orient Thai Airlines with an option for 12 more.

It did not give details on price, but on Monday the company announced a 30-plane deal with Indonesian group Kartika for $951 million. Sukhoi chief executive Mikhail Pogosyan told reporters at the Farnborough Airshow that the company had a firm backlog of 131 domestic and international orders for the Superjet 100 and that 70 percent of testing was complete.

He reiterated an earlier target to make first deliveries to customers by the end of 2010. The project has been hit by a string of delays since the plane's maiden flight in 2008.

Sukhoi said the order with Orient Thai Airlines, which has 15 planes, would be delivered from 2011 to 2014.
