The House Defense Appropriations Subcommittee has signaled that it will entertain, but constrain, President Donald Trump’s plans to create a new military service that focuses exclusively on space.

The House’s version of the fiscal 2020 defense spending bill would provide $15 million for Space Force operations and maintenance, almost $57.5 million lower than the administration’s $72.5 million request, according to the committee report released Monday.

The funding is buried within the massive $690.2 billion bill, but shows the Democratic-controlled House’s caution in proceeding with Trump’s much-touted desire to establish Space Force, which requires congressional authorization.

The funding cut in the House bill, which the Appropriations Committee will mark up Tuesday, could portend a battle when the House Armed Services Committee considers the fiscal 2020 defense authorization bill next month.
