The European Commission said the fund would provide a total of 500 million euros (USD 563 million) in EU money in 2019 and 2020 to help buy and develop military equipment. This would double to 1 billion euros annually from 2020.
The Commission says it expects the money to generate about five times that amount for developing defense capabilities, once member countries make their contributions.
The money would only be granted if a minimum of three companies were taking part from a minimum of two EU member countries.
The executive Commission is also offering grants for defense research. EU countries spend around seven times less on defense research and development than the United States. U.S. President Donald Trump has demanded that NATO's European allies and Canada start spending 2 per cent of gross domestic product on military budgets.

Twenty-two EU countries are also members of the world's biggest military alliance.
"Two per cent of GDP spent separately provides less security than if part of the money is used jointly. As important as the amount of money, is how to use it,"
Commission Vice-President Jyrki Katainen told reporters. Alongside its budget plans, the Commission also launched debate on what direction EU defense cooperation should take once Britain leaves in 2019.
