Answer:
United Kingdom
Step-by-step explanation:
It's obviously United Kingdom.
Take a look at the map of Europe and locate the other countries. None of Switzerland, Czech Republic nor Austria has access to the ocean.
A navy is a branch of the army that operates on the water. If you don't have access to the ocean, you have no need for a navy because you don't need to defend yourself on the water because your enemies can't attack you this way.
