Sweden's Saab has edged out French and US rivals to win a multi-billion-dollar contract to supply Brazil's air force with 36 new fighter jets, Defence Minister Celso Amorim says.
Saab's Gripen NG was in competition with the Rafale made by France's Dassault company and US aviation giant Boeing's F/A-18 fighter for the long-deferred FX-2 air force replacement program.
"After analysing all the facts, President Dilma Rousseff directed me to inform that the winner of the contract for the acquisition of the 36 fighter jets for the Brazilian Air Force is the Swedish Gripen NG," Amorim told a press conference.
He put the actual value of the contract, earlier estimated at $US5 billion ($A5.66 billion), at $US4.5 billion as Saab offered the cheapest price.
The announcement came after more than 10 years of discussions and repeated delays due to budgetary constraints.
It came as a surprise, as experts were forecasting a Dassault-Boeing duel.
Amorim said the Gripen, a state-of-the-art, multi-role fighter, got the nod based on performance, assurances of technology transfer and overall costs.
The Gripen, which was favoured by the air force brass, is capable of performing an extensive range of air-to-air, air-to-surface and reconnaissance missions.
It can carry up to 6.5 tons of armament and equipment.
Munitions include various missiles, laser-guided bombs, and a single 27 mm Mauser BK-27 cannon.
The Gripen is in use in the air forces of Britain, South Africa, the Czech Republic, Thailand and Hungary.
Rousseff had postponed a decision on the FX-2 replacement contract in early 2011 for budgetary reasons but air force chiefs made it clear that it was an urgent matter.
The air force said the new fighter aircraft were needed to maintain an adequate air defence as it is to retire its 12 Mirage jets in late December.
Brazil bought the refurbished Mirage 2000 C/Bs from France in 2005 for $US80 million to fly for five years.
A key requirement for the sale was technology transfers so that the planes can be assembled in this country and give a boost to the domestic defence industry.
Amorim said negotiations with Saab would take 10-12 months, with the signing of the contract expected at the end of next year and delivery of the first aircraft 48 months later.
