A second Sukhoi Su-30SM advanced multirole fighter successfully carried out its maiden test flight on Monday, the manufacturer said.

The first Su-30SM made its first flight on September 21 as part of a comprehensive testing program for the aircraft that has been upgraded for the Russian Air Force.

“The second fighter jet has joined the flight tests,” the Irkut corporation said. “The flight continued for an hour and 40 minutes and went smoothly.”

The Su-30SM is a two-seat version of the earlier Su-27UB and the MKI model supplied to India, and is capable of air-to-air and air-to-ground missions with a wide variety of precision-guided munitions.

The aircraft features thrust-vectoring engines to enhance maneuverability and meets the Russian Air Force's specific requirements.

Russia's Defense Ministry signed a contract with Irkut in March for the delivery of 30 Su-30SM multirole fighter aircraft by 2015.
