How did new naval technology impact world war 1

Answer is stated below.

Explanation:

The naval power was conclusive in the first world war. The Royal Navy of Britain was mightiest and the German competition for supremacy over the Atlantic was one of the causes for the war. But the most important role was played by the Merchant ships which supply foods and weapons and protection of these ships was vital to win the war. Due to blockades of these ships half a million population of the central power perished during the war.

Naval power played a decisive role in the final outcome of WWI. The course of the war on the sea didn't follow the plans layed out by either German or British planners, but naval power was fundamental. German submarines posed a grave threat to allied commercial ships. And the British blockade to damage Germany's economy turned out to be a key factor in the defeat of Central Powers. Most naval operations took place in the North Sea and in the Atlantic Ocean between Britain and Germany.
