Russia's new stealth fighter jet made its public debut Tuesday, according to state-run news source RIA Novosti.

The Sukhoi T-50, developed collaboratively by Russia and India, appeared at the MAKS 2011 air show in Zhukovsky, outside Moscow.

Gen. Alexander Zelin, head of the Russian air force, told RIA Novosti he expects the T-50 prototype to be ready in 2013, with "mass-produced aircraft" arriving in 2014 or 2015.

The aircraft is expected to become a staple of airborne defense for both Russia and India, Mikhail Pogosyan, head of Russia's United Aircraft Corp., told RIA Novosti.

"The T-50 will be the newest main plane both for the Russian and the Indian air force," Pogosyan said.

The article from the state-run media source says the Sukhoi T-50 cost the two governments about $6 billion to develop, with India shouldering about 35% of the cost. It is intended to match the U.S. F-22 raptor.
