2 aircraft carriers built and 2 on order?

Wikipedia says the Gerald Ford cost about $15b including about $3b reusable R&D. But let's say $15b.

Assuming it takes 8 years to build, that's about $2b per annum. This is probably overstated since policy wonks say an additional $2b per annum would rebuild the fleet to 15 carriers in 25 years, but let's go with $2b per annum to buy a carrier.

With a federal budget of over $4T for 2019, the $2b is .0005 or 0.05% of the budget. So for every $100 of budget, you're paying a nickel towards the carrier.

Straining at gnats etc? Not convinced that focusing on the nickel is the best way to balance the books.

You could say the same about Trump's request for $5b towards a wall: that's 0.001 or 0.1% of budget, so about a dime out of every $100. And still they argue over it.

For comparison, you would need to cut a check for more than 3,000 aircraft carriers to match the Medicare spending deficit.
