The legislation, crafted by House and Senate negotiators from both parties, tracks the funding levels for Pentagon procurement, operation and maintenance, and research and development programs authorised by the annual defence policy bill that former President Barack Obama signed into law in December.
The full House is scheduled to meet next week to consider the defence spending bill for the 2017 fiscal year. Once the bill clears the House, the legislation moves to the Senate for a vote.
Trump is expected to deliver to Congress in the next few weeks a supplement to the 2017 spending bill that would boost the total by as much as USD 30 billion. For the 2018 budget year, which begins October 1, Trump is seeking a USD 54 billion increase in the Pentagon's budget.
The Pentagon and other federal agencies are currently running under a stopgap spending bill that expires April 28. Congress approved the temporary measure to avoid a government shutdown late last year.

The defence authorisation bill signed by Obama totalled USD 611 billion, while the appropriations package is roughly USD 33 billion less because the defence spending bill doesn't include money for military construction and nuclear weapons research. Those programs are included in separate appropriations legislation.
Senior US military commanders have pleaded with lawmakers to avoid the frequent use of stopgap spending bills, which are known in Washington-speak as continuing resolutions. Under these short-term agreements, the Pentagon's budget is set at the previous year's level and the military services are barred from starting new programs.
