A South Korean company is close to clinching a deal to sell three submarines to Indonesia.

Daewoo Shipbuilding and Marine Engineering (DSME), which builds submarines, said the South Korean company is the only bidder in negotiations with the Indonesian government to export submarines to the Southeast Asian nation. Indonesia broke off negotiations with France, which had been competing with South Korea for the bid.

A company official said that it has beaten out other countries, including France, Germany, and Russia, to win exclusive rights for the project. The official said it is likely that the company could be named the preferred bidder and sign the contract in November.

Worth a total of one-point-one billion dollars, or one-point-two-trillion won, the project calls for the building of three 14-hundred-ton submarines. A Defense Acquisition Program Administration official said that if the deal is sealed, it would be the largest-ever single export contract in the history of the nation’s defense industry.
