Final answer:
Congress approves Navy funds through the budgetary process, which includes hearings, debates, and setting ceilings for each item in the budget.
Step-by-step explanation:
Congress approves Navy funds through the budgetary process. The President submits his budget proposal to Congress by February 1st of each year.
Congress then holds hearings, debates, and sets ceilings for each item in the budget. During the process, the House and Senate Appropriations Committees determine the specific appropriations, including funding for the Navy.
