What was the purpose of the war ships during ww1?

During World War I, warships played a crucial role in naval warfare, ensuring control of the seas and protecting maritime trade routes. They were used for blockades to restrict enemy supplies, engaging in battles against rival fleets, and supporting ground forces through naval bombardments. Submarines, particularly the German U-boats, introduced new tactics that targeted merchant and military ships, significantly impacting naval strategies and the overall war effort. Additionally, warships facilitated troop transport and contributed to the projection of naval power on a global scale.
