The process of passing the various bills authorizing and approprating funds for the sea services takes several months. Congress must hold hearings, write drafts, hold debate, vote, and then reconcile differences between the House and Senate versions of the same bill. If these bills are not passed and signed by the President by the end of the fiscal year on September 30th, then Congress must pass a temporary funding bill, called a Continuing Resolution, at the funding levels of the previous fiscal year to keep the government operating.
The House version (HR 2810) of the National Defense Authorization Act for FY2018 passed the chamber in July 2017. The Senate version (S 1519) has passed the Armed Services Committee but still must receive a floor vote with the full Senate.
The Department of Homeland Security Authorization Act passed the House of Representatives on July 20, 2017. The bill includes authorized spending levels for the Coast Guard. The Senate has received the passed House bill which has been referred to the Senate Homeland Security Committee.
Fiscal Year 2017 will end on September 30, 2017 and it is likely that Congress will not have passed all the authorization and appropriations bills before then, and will have to resort to using another Continuing Resolutions. Congress also has several important votes in September that add more to the congressional calendar.
