Sukhoi director general Mikhail Pogosyan said in an interview at Farnborough that experience and bench testing allows his company to deliver the PAK-FA to customers in 2015.
Countering Western skeptics, Pogosyan said Sukhoi has delivered four aircraft – the Su-30MKI, the Su-34, the Su-35 and the T-50 – over the past 10 years.
