What were primary reasons for the expansion of the U.S. Navy during imperialism?

The expansion of the U.S. Navy during the period of imperialism was primarily driven by the need to protect U.S. interests overseas. As the United States began to acquire territories and seek influence in different parts of the world, particularly in areas like the Caribbean and the Pacific, it became increasingly important to have a strong naval presence. This fleet not only secured American shipping routes but also ensured that American interests in foreign markets and territories could be defended against potential threats from other imperial powers.

The U.S. recognized that a powerful navy was essential for safeguarding trade routes, territorial claims, and American citizens abroad. Events such as the Spanish-American War highlighted this need, where naval power played a crucial role in achieving victory and subsequently expanding American influence. Thus, the expansion of the Navy was integral in supporting and sustaining the United States' ambitions on the global stage during the late 19th and early 20th centuries.
