The Polish Navy as a prewar sea-denial force

What objectives justified funding the Polish Navy before the Second World War when Poland's main threats were on land?

It offered sea and access denial in the Baltic, guarded against amphibious threats, and supported Poland's regional allies.

The land threat from Germany and the Soviet Union did not eliminate Poland's maritime problem. Soviet experience with amphibious operations meant an enemy might bypass fixed land defenses by moving along the Baltic coast. A modest navy could complicate that option, support regional allies, and add another defensive layer against Germany. Its realistic purpose was sea and access denial rather than an attempt to command the Baltic.
