U.S. President Donald Trump on Monday said he was ordering the creation of a sixth branch of the military to focus on space, a move critics said could harm the Air Force.

“It is not enough to merely have an American presence in space. We must have American dominance in space,” Trump said before a meeting of his National Space Council.

“We are going to have the Air Force and we’re going to have the ‘Space Force.’ Separate but equal. It is going to be something,” he said later.

The United States is a member of the 1967 Outer Space Treaty, which bars the stationing of weapons of mass destruction in space and only allows for the use of the moon and other celestial bodies for peaceful purposes.

The idea has faced criticism from senior military officials.

The move would require the budgetary approval of the U.S. Congress, which has been divided on the idea.
