How has submarines changed over time?

Answer 1

Submarines have evolved significantly since their inception in the 17th century, transitioning from simple, hand-powered vessels to advanced, nuclear-powered machines capable of long-duration missions. Early submarines were primarily used for reconnaissance and limited attacks, while modern submarines are equipped with sophisticated technologies, including stealth capabilities, advanced sonar systems, and missile launch systems. The development of nuclear propulsion has drastically increased their operational range and endurance, allowing them to remain submerged for extended periods without surfacing. Additionally, advancements in automation and materials have enhanced their safety, efficiency, and combat effectiveness.
