What are the takeaways from Ukraine’s fight in the Black Sea?

Defense News – Ukraine has shown surprising naval capability in the Black Sea, helping to protect its shores and shipping while keeping its predator’s fleet at bay. This achievement is remarkable because Ukraine is virtually bereft of warships. It has succeeded through the skillful use of emerging technologies, such as explosive-laden uncrewed surface vessels, and of older ones, such as land-based missiles and naval mines.
