USN can't go some places with USCG icebreakers, so...

The Homeland Security funding bill that includes the $5 billion requested by President Trump for his proposed border wall would scrap a program to expand the U.S. icebreaker presence in the Arctic. The Senate version of the funding bill and an earlier version passed by the House Appropriations Committee both include $750 million for the program, but the current House version of the funding bill does not include money for the icebreaker program. Some lawmakers have blasted the funding being stripped out of the House bill, which includes the full amount requested by Trump for his border wall. The $750 million would restart the construction program and get the first new icebreaker in the Arctic operational.
