Brazil considers the Boeing F-18 the best jet among three participants vying to supply fighter aircraft to the Brazilian Air Force.

Brazilian President Dilma Rousseff said the country would, however, seek improved terms from Boeing as the nation wanted the transfer of proprietary technology to help develop its own defence industry as part of the deal.

The country proposed the purchase of at least 36 fighter jets to modernise its air force in a deal worth at least $4bn, excluding maintenance deals and possible additional purchases.

Boeing is willing to provide technological know-how and assistance in the areas of transport, satellites and weapons systems as part of the deal, while the technology transfer guarantee issue would be decided by the two governments, Reuters reports, quoting Boeing spokeswoman Marcia Costley.

Dassault Aviation exports chief Eric Trappier said the company was ready to transfer all of its available technologies to Brazil if it won the contract.

Brazil is likely to make a decision on the contract by the end of the year.

The other two finalists are France’s Dassault Rafale and Sweden’s Saab Gripen.
