Review Questions

• How did submarine warfare change naval combat strategies during World War I?
  • Submarine warfare revolutionized naval combat during World War I by introducing a new level of stealth and surprise in attacks. The use of U-boats allowed for targeting enemy merchant vessels without engaging in conventional ship-to-ship battles. This tactic disrupted supply lines and forced nations to adapt their naval strategies, leading to the implementation of convoy systems for protection against submarine threats.
• Evaluate the impact of unrestricted submarine warfare on international relations during the early 20th century.
  • Unrestricted submarine warfare significantly strained international relations, particularly between Germany and neutral countries like the United States. By attacking civilian and neutral ships without warning, it violated established norms of maritime conduct. This aggressive stance ultimately contributed to rising tensions that led to the U.S. entering World War I, illustrating how submarine tactics influenced broader geopolitical dynamics.
• Discuss how technological advancements in submarine warfare during World War II affected military strategies and outcomes.
  • Technological advancements in submarine warfare during World War II led to more sophisticated design and operational strategies, such as improved sonar capabilities and advanced torpedoes. These innovations allowed submarines to execute stealthy attacks on enemy supply lines effectively, especially in the Battle of the Atlantic. Consequently, nations had to adapt their military strategies, increasing investments in anti-submarine measures like depth charges and escort vessels to counteract this formidable threat.
