Final answer:
The Executive Branch is responsible for the Navy wanting money to repair its warships.
Step-by-step explanation:
The branch of government responsible for the Navy wanting money to repair its warships is the Executive Branch.
The President, who is the head of the Executive Branch, is responsible for proposing the budget, which includes funding for the Navy.
The President's budget request is then reviewed by Congress, specifically the House of Representatives and the Senate, who have the power to allocate funds to the Navy for the repair of warships.
