South Korea voted against Boeing's F-15 Silent Eagle in its 8.3 trillion won ($7.7 billion) tender for 60 fighter jets, the country's arms procurement agency said on Tuesday, saying it will restart the project.

"DAPA...will swiftly pursue the program again in order to minimize the vacuum in combat capabilities," South Korea's Defense Acquisition Program Administration (DAPA) said in a statement.

Boeing's F-15 had been the only bid out of three that was under-budget and eligible to win the country's largest-ever defense import deal under South Korean law.
