Russia’s Sukhoi aircraft company is carrying out state acceptance trials of its Su-35 advanced fighter jet at the Russian Air Force’s flight test center, the company said on Wednesday.

The aircraft has already undertaken more than 650 flights as part of the trials. The Air Force will accept another six Su-35s before the end of the year.

“The technical characteristics of the aircraft and its military capabilities are in general in line with the requirements,” the company said.

The Su-35, powered by two 117S engines with thrust vectoring, combines high maneuverability and the capability to effectively engage several air targets simultaneously using both guided and unguided missiles and weapon systems.

The aircraft has been touted as "4++ generation using fifth-generation technology."

Russian Air Force Commander Maj. Gen. Viktor Bondarev said on Monday that the serial production of Su-35 could begin as early as in 2013.

Russian Air Force is planning to receive 50 Su-35s by 2015, according to various reports.
