MOSCOW, October 14 (RIA Novosti) – A Russian military delegation about to visit Brazil will offer joint development of a fifth-generation combat aircraft “of the type” of its own most newest fighter to Brazilian defense officials, a member of the delegation told RIA Novosti Monday.

The proposal appears to be in support of an unsolicited offer by Russia’s combat aircraft maker Sukhoi of its Su-35 fighter, that has been struck off Brazil’s shortlist for its air force’s F-X2 tender for the purchase of 36 fighter jets worth $4 billion. Russia is still hoping to sell the Su-35s or similar aircraft to Brazil outside the framework of that tender, sweetening the deal with the new proposal.

“During the talks in Brazil, we are ready to offer our partners deliveries of ready-for-sale advanced aircraft like the Su-35, but also joint development of a next-generation [combat] aircraft of the T-50 type,” the delegation source said.

The T-50 or PAK-FA, which will make up the core of Russia's future fighter fleet, is a multirole warplane featuring "stealth" technology," super-maneuverability, super-cruise capability, and advanced avionics including an active electronically scanned array radar, according to its designer Sukhoi.
