What were some of the advances in naval technology made under Theodore Roosevelt's leadership?

The correct choice highlights several significant advancements in naval technology that occurred during Theodore Roosevelt's leadership, particularly in the early 20th century. Roosevelt was a strong proponent of a modern naval fleet, envisioning the United States as a formidable global maritime power.

Under his influence, the focus on developing submarines marked a transformative approach to naval warfare. Submarines introduced stealth and surprise capabilities that changed traditional naval strategies. Meanwhile, destroyers were also developed during this era, designed to protect larger vessels and serve as fast attack ships, which complemented the fleets' capabilities.

Additionally, the emphasis on flight experiments reflects the growing importance of aviation in naval operations. Roosevelt’s administration recognized the potential of aircraft in warfare, leading to innovations in naval aviation, including experiments with catapults and seaplanes, which would later become essential in naval battles.

These three components – submarines, destroyers, and flight experiments – exemplify the era's significant technological advancements and underscore Roosevelt's role in modernizing the Navy to ensure that it could compete internationally and project American power globally.
